Project Overview

denkr.ai was built by me in my free time as a personal project. The starting point was my fascination with OpenClaw (by Peter) and a simple question: how can this kind of assistant experience become usable not only for technical people, but also for my mom, family, and friends with no technical background.

I wanted to build something that does not feel like a standard chatbot, but like a reliable companion inside the phone: controlled personality, long-term memory, notebooks, skills, tool routing, web search, YouTube search/transcription, session management, and compaction for long-running conversations. It also includes an MCP direction, API/tool-connection possibilities, and multiple LLM providers so behavior can stay useful and stable across different tasks.

Since ChatGPT became public, I have tested almost every major AI chat product. Because of that, my bar for denkr was high: it had to feel more personal, more consistent, and more human than a typical prompt-response interface. Even now, using it daily still surprises me, and that is exactly the product quality I was aiming for.

This is also important: denkr.ai is not a startup pitch and not a monetization project. I built it alone in my free time, it is free to use, and I plan to keep it free. I made it for myself, my family, my friends, and anyone who wants to use it. My 1–2 year goal is to run a strong open-source model directly on the phone and move toward a truly 100% private local agent experience.
