Colyap – AI friend you can call and text

Transform questions into visual, branching knowledge maps that show the bigger picture.

Build update: testing whether visual AI maps are actually clearer than chat This week I finished a public beta of BranchAI, a web app that turns a complex question into a visual tree instead of a single long AI conversation. The hypothesis is simple: people lose useful context once a chat has several follow-ups. Keeping those follow-ups visible as branches should make research and complicated topics easier to revisit. What is working now: - Generate a starting map from a question - Op

I built an AI powered language learning app (without creepy AI characters) Called it Speaka. I’m an expat in Germany and have had my fair share of struggling with the language specially being put on the spot and having to speak. So I have built a web app speaka.app to help. Free to try and use daily. Useful Functions: - Real life scenarios - Custom scenarios tailored to your level - Using the best AI speaking models for flow and tone - Feeback and improvements -
