I've been hesitant to go down the rabbit hole, maybe I will now after seeing so many fantastic use cases that fit within my genre of doing business.

GPT is just making my side project extremely exciting and faster to execute. I have created quiz using GPT automation script and have got 20k+ monthly quiz attempts.

I love using GPTs. I have made several for different use cases, such as competitive analysis and user research. Way more powerful than the out of the box ChatGPT experience.

I made a bot that uses Product, Analytical, and Execution Sense along with a large knowledgebase to create PRDs, do competitive analysis, create Roadmaps with Epics & Stories, and act as an expert product colleague and mentor.

It surpassed the capabilities of Open AI's GPTs, so I have a web app instead. In private beta at https://pimm.ai

Thanks for mentioning my 'PM Product Sense interview prep' custom GPT! It's interesting to see how many conversations it has every day.

I use ChatGPT a lot as my personal assistant.

I feel it needs a lot of help and direction, but once you provide that, ChatGPT is able to do the core 60-70% of the work leaving the final polishing to you.

I work well with my assistant ChatGPT, and - all considered - it's quite a cheap employee!

Thanks for sharing!

What kind of help and direction do you find it needs most? Any tips you can share with folks?

In the Custom Instructions I am very specific about what type of tone, diction, format, I want it to use when producing responses. This works somehow well, however I find that often I'll have to remind it what format I want.

Also, I play around a lot with prompts. I created a personal bank of prompts I save in Obsidian and I use them every time I'm going through a specific exercise and I need a particular "voice" (I learned a lot from Nicholas Cole and Dickie Bush on these things).

Ultimately, as with all technologies, the more you practice the more you'll find out about it.

Hi Lenny - I built a GPT I trained based on a great deal of custom content I developed over the years at Amazon, Google, Meta, and startups. I'd be interested in your take: https://chatgpt.com/g/g-Q8CX1ZC8P-product-partner

Thank you for this! 🙌🏻

I've been looking to find people who are getting the best out of LLMs and what interesting conversations are they having.

here's how I use GPT proudly:

- On decision making (zooming out): To avoid cognitive biases while decision making built this https://chatgpt.com/g/g-jgzCM96eF-beawareofyourbiasesgpt (the idea is to know your blindspots and get the outside-in view

- PRDs edge cases: GPT solves me the programming mindset, does red teamming and edge cases that needs to be solved for a feature/product

- (Chain prompting and clarity in writing is prerequisite) One hack I always use is, I'll ask it to create tables and ask it to assign confidence % it has in terms of prioritisation/prediction

For eg. "Find me most unsexy and most inefficient industries where potential of AI disruption is high, creating high profit pools

Present in a table; Industry, why inefficient, AI disruption potential, how can AI disrupt, gross margins, your confidence %"

Love these examples, it is tempting me to build my own custom GPT. I accelerate strategic projects with Human-Centered Strategy and other tools, so a Chatbot would help those that I work with. I'm just not sure whether I want to invest time building in ChatGPT. I've read that Claude Opus (the free version) is generating better results than the paid version of ChatGPT. I tested Claude for the last 2 days and think it is excellent in writing in a more human-like manner, with better more "thoughtful" answers. Any thoughts Lenny or others on which AI is a better bet for custom GPTs?

I do hear Claude is smarter than GPT-4, but that's just until GPT-5 comes out. It'll keep going back and forth. I think the most important thing here is to get comfortable at using these tools, not necessarily be using the top tool at any one time.
