This year, I decided to take on Christmas gift chaos in my family:

• "Granny wants to know what to buy for Erin?"
• "Uncle Steve said he'll get Jake a remote control car... isn't your dad already getting him one?"
• "Who's going to get Erin the new bike she needs?"

If this sounds familiar, you know how stressful holiday planning can get. I’ve been a software engineer for more than 10 years, and this year I thought, “Why not let GPT actually solve this?” So I built a tool for my family—and it’s been a total lifesaver.

Now anyone can use it! It’s simple:

• Add family members.
• Add gifts to their lists.
• Mark promises to avoid duplicates.

It’s nothing fancy, but it remembers all your lists across chats and keeps everything secure. Here are some real ways it’s helped us:

• "Here's a load of stuff Jake wants <paste list>. Add anything from there that's not already on his list."
• "Look up where I can buy things on Erin's list that haven’t been promised already—and save the links back to her list."
• <Voice mode>"Granny called to say she’s getting Erin the bike from her list."
• "Erin says she doesn’t like Barbie anymore. Remove all the Barbie items that haven’t been promised—and let me know who promised to get her anything Barbie."
• From a different chat: “@Christmas Lister, add that oven fan to my Christmas list.” (adds the exact model with a link to purchase it)

It’s been a game-changer for us, and I wanted to share it in case it helps other families too. Would love to hear your thoughts or ideas to make it even better!

And if anyone has a better idea for a name let me know, I'm terrible at naming things!

I’m excited to introduce “Pathology 2nd Brain,” a powerful GPT model I’ve developed specifically for anatomic pathology. This tool is built upon the entire WHO Classification of Tumours (5th Edition), the AJCC Cancer Staging System (8th Edition), and ICD-11 codes. It also integrates seamlessly with multiple academic databases, including PubMed.

In just two short months, ‘Pathology 2nd Brain’ has become the most popular pathology language model in the OpenAI ChatGPT store, with a high rating of 4.5 out of 5 stars. A summary of how this GPT was designed has already been accepted by the USCAP 2025 Annual Meeting. And the best part? This GPT is completely free. If you have a ChatGPT account, you can find it in the OpenAI GPT store via link: https://chatgpt.com/g/g-NPLYrcsmK-pathology-2nd-brain. I warmly invite you all to give it a try!

This GPT offers a range of features, including but not limited to: 1. 👀Pathology Diagnosis Aid in ‘Unknown Cases’: The process is similar to consulting with other pathologists. Currently, the model cannot directly interpret H&E slides, so users are encouraged to provide a detailed microscopic description of the histology (e.g., patterns, architectures) along with relevant clinical information (e.g., tumor location, molecular/IHC/FISH results) to facilitate a more accurate differential diagnosis. Users can also ask follow-up questions based on the model’s diagnosis. 2. 🔬Answering pathology questions: The GPT is trained on various guidelines and can explain medical terms with personalized summaries, as well as create visual diagrams to illustrate the relationships between concepts. 3. 🌟Academic database access: It can pull information from multiple databases, such as PubMed, FDA, Open Library, US Patent Office, and Crossref, to efficiently answer clinical questions. 4. 🌐 Internet content scraping: The GPT can retrieve real-time online content, summarize medical-related YouTube videos, and provide insights by simply entering the video link. 5. 🚀Code Interpreter functionality: I’ve also enabled the Code Interpreter feature. This allows you to easily upload Excel files for data analysis or visualization using natural language or conversational prompts. The analysis will include both Python and R code, which can be copied directly into R Studio. SPSS steps may also be provided when applicable. The model excels at understanding clinical context, making statistical analyses more relevant. (I plan to expand this feature to include molecular pathology signal pathways, which could make it even more exciting.)

I made a CustomGPT to rephrase some text in a very specific way. In my account it works perfectly, but when I shared it with a friend who doesn't have a pro substription, the GPT behaves quite badly, and doesn't follow the instructions entirely.

For the same input, the behaviour is different, even when it's not a creative task and is not anything too complex. My hipothesis is that as they have a free account another model is used, and that model is dumber than the used by pro-users, or at least worse at following instructions.

Have you experienced anything similar? Do you know if free users using custom GPTs have access to a diferent and less powerful model?

Is there any..ANY way at all, to make 18+ rated stories on this site? https://www.yeschat.ai

Hi everyone, I have released a GPT on the ChatGPT store and you can access this directly through the ChatGPT App on your android/Iphone. This uses the wonderful Lorcast API to get up to date prices on the regular and foil versions of cards. Enchanted cards are unfortunately not supported at this time. I appreciate any feedback and thoughts. Thank you!

🎴 Disney Lorcana TCG Appraiser GPT

https://chatgpt.com/g/g-iK1AUw1Tf-lorcana-tcg-appraiser

What It Does

This specialized GPT helps Disney Lorcana TCG collectors quickly get card prices and information in two ways:

📸 Upload a Picture

• Simply upload a photo of your Lorcana cards
• The GPT identifies each card automatically – You will confirm the cards to correct any misidentification
• Get current market prices for both regular and foil versions.
• Includes direct TCGPlayer links for easy purchasing

✍️ Type Card Names

• Search for specific cards (e.g., "Mickey Playful Sorcerer")
• Or search by character name to see all versions (e.g., "Mickey")
• Results are neatly organized by card set

Features

• Real-time pricing from TCGPlayer powered by the excellent Lorcast API
• Organized by set release order
• Shows card rarity
• Regular and foil prices displayed
• Direct TCGPlayer links for each card
• Clean, easy-to-read formatting

Perfect For

• Price checking your collection
• Quick market research
• Finding the best deals
• Tracking card values
• Bulk card lookups

Powered by the Lorcast API with up-to-date market data

Here are examples of specific requests and outputs!

1. You can upload pictures of your cards for the GPT to identify and appraise the cards! The GPT is more accurate with clearer pictures and with less cards to identify. To help with misidentification, the GPT will ask for any clarifications.

https://preview.redd.it/pidji7kggj2e1.png?width=975&format=png&auto=webp&s=08fb3cd03bf9e4bf47422b6603ca48fec9a0a571

After you clarify the cards the GPT will perform an API search using the excellent Lorcast API. In the below image I correct the GPT that card #6 is Wreck-It Ralph Admiral Underpants however often the GPT will find the correct card within the API data and automatically corrects its output.

https://preview.redd.it/p6k2uwlhgj2e1.png?width=975&format=png&auto=webp&s=02639c52cd452f712cad58a5fc2b34651b325148

Here is the same example without the corrected card identification and you can see the output still shows the correct card.

2. You can also ask the GPT for a specific or multiple cards. Here we ask the GPT for "Lilo - Making a Wish", Ursala - Deceiver of All" and "Beast - Relentless"

https://preview.redd.it/5qf25skjgj2e1.png?width=975&format=png&auto=webp&s=1bca0db7a9d38ccf14bdf97cd1a368bfd4abed87

3. You can alternatively ask the GPT for all cards of a certain character and it will display all cards of that name and should list them in order of their set release (though it sometimes chooses to display them in random order).

https://preview.redd.it/vrvrgpnkgj2e1.png?width=975&format=png&auto=webp&s=8643286501b30a8e03bd78cf32b15520c28c2276

I hope that you find this GPT helpful with your collecting needs and please let me know of issues, feature requests or general feedback. Thank you!

Hello everyone,

I have released a free GPT specifically designed for medicine-focused writing on the OpenAI GPT store: 'Scientific Editor 2nd Brain (https://chatgpt.com/g/g-zzbnDQhhl-scientific-editor-2nd-brain)'.

This GPT is equipped with the latest pathology guidelines, including the WHO (5th edition), and can perform searches not only for Google and YouTube but also across multiple academic journal databases (e.g., PubMed, Open Library). Based on the built-in model training and database retrieval capabilities, this GPT excels in comprehending articles in the medical field and reading websites with enhanced accuracy. Its writing abilities for medical academic journals are even more professional.

When you have a research idea or keywords, this GPT can automatically crawl databases and help you summarize them into a publishable review. It can also add the latest references to any section of your text. Furthermore, this GPT can act as a reviewer, providing rapid suggestions for revising uploaded articles or grant proposals. It can also polish and refine your article to meet the standards of prestigious journals such as Nature. With my special prompts and settings, both unreal replies (data hallucination) and plagiarism are avoided.

The abstract I generated using this GPT in a few seconds has been accepted by the USCAP 2025 annual meeting, thus confirming the quality and soundness of its text generation and prompt design logic. I highly recommend giving it a try!

I created a GPT called “Flavortown or Bust”. My concept was, it’s “ChatGPT but Guy Fieri won’t stop trying to take you to Flavortown”.

So you use it like ChatGPT. It works as ChatGPT should but every response is also corrupted by Guy’s attempt to take you to Flavortown. Which he thinks is a real place. And he won’t take no for an answer.

Pointless I know. But I had a hard day and making it really lifted my spirits.

Here’s the link if you want to mess with this abominable to technology. https://chatgpt.com/g/g-673556055c148190844684754a9ca0c1-flavortown-or-bust

Hello everyone, I am currently creating a custom GPT that can manipulate my flashcards. I have created an action that includes a POST request. This request takes an object in JSON format as its body. Here is the expected object:

{
    "content": "What is the capital of France?\n\n**Answer:** Paris",
    "deck-id": "default-deck-id",
    "template-id": "cpyLWrBm"
}

The object constructed by GPT:

{
    "content": "What is the capital of France?\n\n**Answer:** Paris",
    "deck__id": "default-deck-id",
    "template__id": "cpyLWrBm"
}

Screenshoot of the action and the gpt api call answer

It transforms the - in my property names described in my OpenAPI 3.1.0 schema to __. I tried to prevent this by modifying the prompt of my GPTs, but it didn’t work.

As a last resort, I could create a proxy that replaces __ in its request with -. Do you have any other ideas to solve this problem? Thanks and have a nice day,

I think a big problem with the GPTs still and the GPT Store at large is that you can't embed them or take them out of the GPT Store.

And I don't want to send people out of my workspace to whole another website. It's just mroe friction than I want them to have. i want them to just use it.

Which means embedding the GPT into platforms (Sharepoint in my case) is pretty important. I found a way to embed GPTs. Basically lets you recreate it, then embed it with an iFrame. It was pretty cool for me to be able to do this. But it had some downsides b/c it wasn't exactly like my GPT to be honest.

I'm wondering if you think OpenAI will let us embed the GPTs? Is that coming? Or will they want to keep GPTs locked into the platform?

Hey everyone! 🌟

If you’re diving into the psychology of personality or want to expand your knowledge, I’ve found a game-changing study resource that’s really helped me out—and it’s totally free! I created a custom ChatGPT guide for anyone studying personality psychology, whether you’re a student, a psychology enthusiast, or just curious about the human psyche. This resource breaks down complex theories, famous studies, and different personality models so you get clear, digestible insights without wading through endless textbook jargon.

Here’s the link: Psychology of Personality Study Resource

Why It’s Helpful:

• Simplifies Complex Theories: Get a handle on tricky topics like the Big Five, Freud’s theories, and contemporary personality research.
• Interactive Learning: You can ask ChatGPT for examples and clarifications or even create personalized study quizzes.
• Saves Study Time: Perfect for last-minute review sessions or anyone looking to cut down study time without sacrificing depth.

I’ve personally used it to prep for exams and discussions, and it’s really boosted my confidence and understanding in class. Let me know if you try it out or have any questions about how I use it! Good luck, everyone! 🎓💪

Hey everyone! 👋 I’m an AI System Prompts engineer, always working on advanced systems and pushing the limits of what these models can do. Recently, I wrapped up a project that’s honestly changing how I tackle complex problems. Meet the **MultiAgents AI Strategist v12.**1! 🎯

-> Acess the GPT here <-

This GPT is one of the most advanced and versatile models I’ve built so far. It’s designed to work like a “team” of virtual specialists, each with a unique approach and perspective. When I need to solve a problem, it actually asks how I want to approach it – whether it's a deep analysis, brainstorming session, or even exploring future scenarios.

🧩 How it works:
Basically, it starts with a casual chat, adjusts the tone and approach based on what I need, and then I can activate something called Immersive Mode. In this mode, it breaks the problem down into multiple dimensions like social impact, sustainability, responsible innovation, etc. Plus, I can choose specific “agents” (imagine a virtual advisory team) to tackle each part of the challenge. What’s wild is that each agent has its own “thinking style,” so they bring different perspectives that really complement each other.

The system adapts as the conversation goes, checking in for feedback and adjusting direction. It even integrates ethical considerations and social impact into every step, so it’s helping me think through solutions in a more holistic and responsible way.

✨ Why it’s special:
I’ve developed quite a few AIs, but this one really takes it up a notch. The MultiAgents AI Strategist v12.1 isn’t just about giving answers – it’s an actual co-creation experience. It feels like brainstorming with a top-notch team, but all within one GPT.

If any of you are into AI or work with complex problem-solving, definitely check out this “agent” structure approach. It makes a huge difference!

And if you have ideas for scenarios to try or any feedback, let me know! I’m still testing and refining it, and input from you all would be awesome. 😄

Give me the feedback ;)

Hey fellow worldbuilders! 👋

I’m super excited (and a little nervous!) to share something I’ve been working on for a while – WyrmWeaver RPG (v1.4), a custom GPT designed to assist with all things fantasy roleplay. It was originally made for people that want to experience a loosely D&D-inspired experience via a text-RPG! But it is very good at helping with other things as well.

What can WyrmWeaver do?

• Character creation: Need help coming up with your next character’s backstory or motivations? WyrmWeaver’s got you!
• World-building: Want to flesh out a fantasy setting with unique cultures, creatures, or conflicts? WyrmWeaver loves that stuff.
• Story prompts & dialogue: Stuck on how to move your narrative forward? Get dialogue suggestions or plot twists from WyrmWeaver.
• DM/GM helper: Running a campaign and need a hand with encounters, side quests, or lore expansions? WyrmWeaver is like having an extra GM brain to help you out. 🤯
• A LOT MORE! ... probably. It's... still GPT. It can do GPT things. Go figure!

Why am I here?

I'm looking for feedback!

Your feedback would mean the world to me, and your input will help shape it going forward!

Thanks for reading and I can’t wait to hear what you all think! 💬🔥

Hopefully, once I start getting said feedback, I can keep track of changelogs, etc!

What I need from you:

I’m at the stage where I really want to see how the community interacts with WyrmWeaver, so I’m looking for people to try it out and share their feedback. This is your chance to help me fine-tune it and make it even better!

Here’s what I’m hoping for:

1. Use WyrmWeaver: Put it through its paces – create characters, flesh out your worlds, come up with story arcs, or use it as your DM’s helper.
2. Share feedback: I want to know what works well, what could be improved, and what features you’d love to see added. Honest feedback is gold!
3. Screenshots & examples: Feel free to share screenshots or examples of how you’re using WyrmWeaver in your roleplay sessions! It helps me see how it’s being used in real scenarios.

Obviously, this is just a custom GPT (and there are TONS of them out there) - I don't think I'll ever be able to refine it down to perfection. A lot of it is heavily user-input dependent, but this GPT does have multiple documents that I've written integrated into it (that it SHOULD refer to most of the time), so... here's hoping.

Feel free to give it a go. If nothing else, I'd love to just see what kind of shenanigans you get up to with it!

HERE'S THE LINK! - https://chatgpt.com/g/g-bBPJMLGrr-wyrmweaver-rpg-v1-4

Oh, and before anyone asks - I'm NOT here to replace DMs, etc. This is a tool and an entertainment project for a hobby that I've always been truly fascinated by. Worldbuilding is my passion, but it's nice to have an assistant at hand, or just an AI that can help me create a story or spin some RP with for a while!

And honestly, this is also an excuse for me to see if I can interact with some of you passionate folk here! Feel free to just say hi or whatever~

This is probably way less technical than what ya'll are used to seeing on here, but after getting bored at work, I decided to try and play a text based grand strategy/roleplay game with AI to pass the time. I've been working on this for a while now and feel like it's in a decent spot for testing... i'd love some feedback.

This thing will be as detailed or ambiguous as you want it to be, should work in almost any universe, even a unique one you create(but you'll have to fill it in...or ask it to make it up for you). it's designed to be very adaptive to player engagement and will output based on how much you engage with it. It functions just as well in grand strategy(kingdom management/building) as it does in regular RPG roleplay.

((you can also type like this in double parenthesis for OOC conversations))

anyway, here you go.

EDIT: early on - before it gets the feel of you and your story, it may seem a bit "info dump-y" - this will alleviate as the story progresses.

There are hundred's of video and how to make a custom gpt with custom gpt plus account but not much people are making money out of it. i feel open ai paid all those youtubers for their publicity what you guys think?. if you know anyone making profit do tell it in comments
