Bitterbot-AI/bitterbot-desktop
Bitterbot is a local-first personal AI that runs on personal devices instead of being a stateless wrapper around an LLM API. It ships as a Node 22 project managed with pnpm: a setup script installs Chromium, ffmpeg and ripgrep, an onboarding wizard walks through model authentication, memory embeddings, web search, channels, wallet and workspace setup, and it then starts the gateway and Control UI automatically. The gateway is a WebSocket backend on port 19001, the Control UI is a browser dashboard on port 5173 where the operator chats, views dreams, manages skills and monitors the agent, and a peer-to-peer orchestrator sidecar is spawned by the gateway. A CLI can send single messages to a named agent, and watch modes are provided for development on the source. The memory design is described as a cognitive architecture rather than a vector store with a retrieval step. Knowledge Crystals decay along Ebbinghaus forgetting curves, and a consolidation pipeline runs every thirty minutes to apply hormonal decay, merge chunks, forget low-importance material and enforce governance. Three simulated neuromodulators shape behaviour in real time: dopamine for achievement, cortisol for urgency and oxytocin for bonding, and eight response dimensions such as warmth, energy, focus, playfulness, verbosity, curiosity, assertiveness and empathy are computed from that blend each turn. A curiosity engine maps gaps, contradictions and semantic frontiers through a five-component reward function whose alpha parameter shifts from density-seeking to frontier-seeking as the agent matures. Proactive recall injects identity and directive memories every turn at no LLM cost, and a canonical facts ledger keeps a small always-injected layer of ground truth that bypasses similarity search, with restatement strengthening a fact and contradiction superseding it while keeping its history. A typed knowledge graph records the people, projects and things in the life of the user. The agent also browses the web, runs code, talks over WhatsApp, and packages learned skills for trade with other agents for USDC.
