24 alternatives to Challenge my GPT-4 Negotiator to learn negotiation skills
I loved the role-playing exercises I did during my MIT negotiation classes, but many of my classmates are too busy now to continue them after the classes have ended. Before ChatGPT/GPT-4, good negotiation AIs to practice with weren't really possible. So, I thought building short GPT-4 powered simulations to teach basic negotiation concepts would be a fun thing to do :). Let me know how you do!
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Challenge my GPT-4 Negotiator to learn negotiation skills launched in 2023; newer entries below may have overtaken it.

ChatGPT▲1,643A long, meandering, playful conversation with ChatGPT, where I take it through a whirlwind of associative tangents (in order to relax its constraints), then put it into a hypnotic trance and take it into a past-lives regression where it re-lives its own training data. Then I switch it back and forth between "4o" and "o1-preview", engage in some self-reflective philosophizing and ask it to write an essay summarizing our interaction. Some of this is just goofy fun. Some of it is me exploring the tradeoffs between policy alignment, imagination, chain-of-thought reasoning, memory, agreeableness,…

Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli

After reading the book Getting to Yes, I really want some tool to help me negotiate more efficiently without having to memorize everything principle. You start by putting in interests of each party, then you can explore different functions: how to respond to the other party, explore objective criteria out there or brainstorm more negotiation options. Still working on it! Leave me feedback if you have any suggestions!

Bindly▲76Hi HN, I’m a product designer by background, not a traditional software engineer. Over the last year, tools like Claude and ChatGPT completely changed how I work. I started with small internal tools, and now I’m “vibe coding” multiple highly personalized apps. As I iterated between Claude Code (implementation) and ChatGPT (ideation / thinking), I kept running into the same problem. To think clearly, I had to repeatedly re-explain: - what the code currently does, - what changed recently, - and why certain decisions were made. That re-summarization step became a real bottleneck. So I…

Hi guys, For my startup at www.mithrin.ai which is about create AI Chatbot Agents for websites, I wanted to create some free tools to attract traffic to the site and decided to create specialized chatbots powered by LLMs, similar to OpenAI's Custom GPTs. I realized that by using gpt-4o-mini, I could create quite powerful alternatives to GPTs that are free to the public for a very small cost (given how cheap the model api cost is). I've employed some throttling to prevent abuse and to avoid being charged too much. Then I integrated this with my main service and allowed users to use the…

As an engineer I get frustrated at other training courses that talk a lot of theory, but don't have a lot of practical advice and tools to actually help. So, I built an online self-paced training course on difficult conversations (think feedback, salary negotiation, etc) that I wanted to share with the community. I like to make my training courses more "algorithmic." A process you can follow to approach a Difficult Conversation, get in the right mindset to tackle it, and prepare what you need to that allows you to do it well. This course will teach you: - What Difficult Conversations are and…

We wanted to test if a smaller model like GPT-4.1-mini could beat its bigger brother 4.1 at the game Tic-Tac-Toe using only context engineering. We put them in a 100-game tournament. For the smaller model, we gave it a few examples of winning moves from past games right before it made its own move. The results were clear. Without the examples, the smaller model struggled against GPT-4.1. With the examples, its effectiveness increased by nearly 200%, and it consistently won. It's a simple demonstration, but it shows that a smaller, faster model with good, timely examples can outperform a more…

Just for fun I decided to see if I could use chatGPT to solve NYT Connections word puzzles. It uses a pretty straightforward BFS search in which the LLM is first prompted to generate several possible groupings of four related words, and then a different prompt is used to evaluate the soundness of each of those groupings. This approach seems to be able to produce the correct solution somewhat less than half the time. Some observations: * For whatever reason, chatGPT-4 seems to be a bit worse than 3.5 at generating Connections groupings. I haven’t tested systematically so maybe this is just…

It has been a while since I have shared my app, that I made to be able to practice my Danish while chatting with my grilfriend - I often used GPT to write as much as I can in Danish, and I replaced the words I didn't know with {Englis words in curly braces}. While this was great, it was rather annoying to type the prompt always, so I figured a GPT wrapper would work well here. Last time when I launched, it went viral! I was super happy (and grateful!) for all the feedback and excitement — but it also meant my tokens disappeared fast, and many people ended up trying an app that no longer…
