Product 03AI + Trading · Own product

Crypto Trader

Autonomous crypto trading powered by hybrid AI

Fullstack platform for autonomous BTC and ETH trading on Binance with one clear rule: backtest-calibrated plays decide and the LLM can only veto. Eight AI agents with their own roles (market, risk, blockchain, orchestration), each on a model picked by score from the OpenRouter catalog. Multi-user, with sandbox, testnet and live modes, OCO orders and a real-time dashboard.

Video Maker

An AI video producer that works with your own footage

Video editing and post-production studio for social media (Reels and TikTok in 9:16, YouTube in 16:9). Tell the AI producer what you want, drop in your clips and photos, and it builds the script, cuts, animated captions, voice-over and music; you confirm every step. The engine runs entirely on your Mac: a declarative TypeScript pipeline on Remotion, FFmpeg, Whisper and Piper, packaged as an Electron desktop app. Only the conversation with the producer leaves the machine, to Claude or OpenRouter models.
