# garrytan/gbrain > A personal and company memory layer for AI agents: stores facts with sources, supports corrections and sharing across agents, and adds semantic search, answer synthesis, and a knowledge graph. Runs as a local daemon with background enrichment and memory consolidation. - Magnitude: 2.0 out of 10 — Steady - Stars: 30,617 total · +1 star measured 2026-10-07, 11:05–12:46 UTC, ≈ 8 by evening - Star trust: star growth looks organic - Category: AI agents · Language: TypeScript · License: MIT · Created: 2026-04-05 · Last push: 2026-10-07 - GitHub: https://github.com/garrytan/gbrain · Page: https://gitnova.dev/en/r/garrytan/gbrain ## Useful for - Attach GBrain to an existing agent (Claude Code, Codex) to persist memory across sessions - Expose your knowledge base over MCP via Tailscale to query it from any device - Ask about a person or company and get a synthesized answer with source citations ## Why it’s here - Star-counter measurements on 2026-10-07 (UTC), 11:05–12:46: 30616 → 30617 stars (+1). This is the change over that interval. - Estimated end-of-day forecast: about +8 stars, using observed gains and the previous day. - GitHub Trending TypeScript today: #7, +40 stars. - About 6 forks a day — people are taking the code. ## Star trust Star growth looks organic. Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer. ## Numbers - Forks: 4,595 - Issues and pull requests: 6,243 - Watchers: 140 - Average over the last week: 28 per day - Usual pace: 36 per day - Stars in the last hour (measured): 5 - Latest release: v0.60.102.0 (2026-10-07) ## Stars per day, last 30 days (oldest → newest, today is partial) 2026-09-08 … 2026-10-07: 45, 36, 32, 34, 25, 36, 39, 44, 52, 48, 52, 42, 33, 35, 38, 38, 32, 27, 24, 39, 32, 26, 27, 28, 30, 20, 47, 27, 32, 1 ## Spotted in now - GitHub Trending TypeScript today: #7, +40 stars ## Similar by description 1. **mem0ai/mem0** — 3.1 · Steady · AI agents · Python · +67 stars measured 2026-10-07, 00:22–12:41 UTC, ≈ 118 by evening A long-term memory layer for AI agents and apps: stores user preferences, session state and facts so assistants keep context across conversations.

Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast. Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
