GalaxyBrain is a local-first information operating system that combines a structured editor, a database, and a simple programming language into a single no-account tool. Pages aren't static documents — they contain live variables and formulas that auto-update, with all data stored as structured JSON on your filesystem. Think Notion meets a spreadsheet runtime, but entirely local and offline by default. The developer-facing hook is its built-in MCP (Model Context Protocol) tool, which makes GalaxyBrain directly addressable by AI coding assistants like Claude Code. An agent can read, write, and query your GalaxyBrain workspace the same way it would a filesystem or database — making it a compelling personal knowledge base substrate for AI-augmented workflows. The local JSON storage means no vendor lock-in and full data portability. GalaxyBrain launched quietly on Product Hunt today with 86 upvotes. Its "no account required" positioning and local-first architecture are resonating with privacy-conscious developers who've grown wary of SaaS tools that vacuum up personal data for AI training. The built-in MCP support in particular sets it apart from comparable tools like Obsidian or Notion.

omi is an open-source AI platform from BasedHardware that runs continuously on your desktop and mobile devices, capturing screen activity, audio from meetings, and conversations in real time. It synthesizes everything into a persistent memory graph — you can later ask it what was decided in a meeting last Tuesday, what was on-screen during a debug session, or what a colleague said during a standup call. The platform spans macOS, iOS, Android, and even open-hardware wearable devices. The new v0.11.333 release (shipped April 18) adds significantly improved background processing, better MCP integration for feeding memories into coding agents, and a faster ChromaDB-backed retrieval layer. It claimed 824 new GitHub stars in a single day, the highest star velocity on GitHub trending this week. With 300,000+ active users and 10,000+ total stars, omi has quietly become the most widely deployed "always-on" memory layer for AI workflows. Its open hardware companion (a small wearable device) positions it beyond software into ambient computing.
Reviewer scorecard
“The MCP integration is the killer feature — I can use Claude Code to query and update my personal knowledge base without any manual copy-paste. Local-first JSON storage means I own my data and can version-control it. This is the personal knowledge tool I've been looking for.”
“MCP integration is the killer feature here — being able to feed real-time meeting context directly into your Claude Code session without copy-pasting is something I've wanted for two years. The 824 stars in one day tells you this resonated with real developers immediately.”
“Local-first tools live or die by their sync story. Right now GalaxyBrain appears to be single-machine — no mention of cross-device sync, collaboration, or mobile access. For a solo dev that's fine, but the moment you need to access your notes from your phone, this breaks down.”
“Continuously capturing your screen and all audio is a massive privacy surface. Most workplaces explicitly prohibit recording meetings without consent, and storing that data locally doesn't make the capture part legal. Proceed with caution and check your employment contract.”
“MCP is quietly becoming the standard interface between AI agents and personal information stores. A tool that natively supports it as a first-class feature — while keeping data local — represents the right architecture for an AI-augmented future where you remain in control.”
“This is what a true second brain looks like — not a note-taking app, but a persistent ambient layer that captures life as it happens. The open-hardware wearables angle is early but points to a world where your AI context travels with your body, not just your laptop.”
“Live variables and formulas in a writing tool are genuinely novel for non-technical creatives managing complex projects. Being able to have a word count goal that updates automatically, or reference a character list that stays consistent across documents, is compelling.”
“For content creators who reference past work, client calls, and visual research constantly, having an AI that already has all that context without being explicitly fed it is genuinely transformative. Auto-generating meeting summaries and action items alone saves hours per week.”
