Sidebrain – Cloud AI assistant with persistent memory (web+Telegram) is a business in show hn launch.

Profile

I built Sidebrain as a simpler alternative to local-first AI agent tools like OpenClaw that are blowing up right now.The core difference: Sidebrain is fully sandboxed and serverless. No filesystem access, no Docker, no terminal. It runs on Vercel + Supabase with row-level security. You get 24 built-in tools (web search, GitHub integration, code execution, voice transcription, image generation, reminders, stocks, weather, translation, and more) but the AI can't touch your computer.Key features: - Vector-powered semantic memory that persists across conversations- Works from the web app or Telegram- BYOK (bring your own Claude API key) — your keys, your compute- AES-256 encrypted API key storag

Its activity falls under show hn launch; the profile below is assembled from public directory data.
