Trainy is made for you to learn how to build AI products, without being fired in real life.
It seems like every company in the world wants to use AI (for whatever reason). At the same time, 95% of their workforce has no clue how to do it. Plus, AI jobs are the hottest right now but talent is scarce. So basically, everyone needs to up-skill.
I'm not an ML engineer so struggled to learn how to build an AI product. Took me months and a bunch of mistakes. So I decided to try to fix it.
Trainy is a simulator to replicate the experience of building an AI product from within a large company. You interact with agents representing CEOs, CTOs, Compliance, etc who have their own expertise, way of looking at things and even personalities. If you screw up the CEO will actually fire you.
The full simulator is still being built but on this link you can experience a few scenarios. Would love to hear what you think feels off about the interaction.

Open-source alternative to Navattic for creating interactive product demos.
Turns product testing into a Reddit-like sandbox: spawn opinionated AI personas, run threaded chats and collect 'insights' before you go public. The UI hints at practical workflows (Input / Personas / Chat / Insights and 'real data input now supported'), but the product's usefulness will hinge on persona fidelity, dataset provenance, and how it handles bias and edge cases.
Replaces expensive lab equipment with exam-accurate simulation, logging precision and calculations.
Clever use of Claude Artifacts to gamify social anxiety practice.
