ChatGPT's memory feature in an open, portable format
Epicenter is an ecosystem of open-source, local-first apps that share a memory. We store all your work—notes, transcripts, chat histories—in a single folder of plain text and SQLite. Every tool we build shares this memory: your text editor, personal assistant, etc.. It's open, tweakable, and yours. Grep it, open it in Obsidian, host it wherever you like. The choice is yours. Our vision is to build a personal workspace where you own your data, choose your own AI models, and replace siloed apps with open, interoperable alternatives. All while preserving authenticity and being free and open source. ❤️
Epicenter positions itself as an open-source, local-first ecosystem that uses plain text and SQLite to share a single memory across multiple apps. It emphasizes data ownership, no cloud lock-in, and the ability to run tools locally with a unified memory model.
Everything in Epicenter revolves around a single folder of plain text files and SQLite databases that constitutes one shared memory. Users can record transcripts (e.g., meetings) with Whispering, edit them in Obsidian, and query with AI, all without exporting or copying. The platform supports local-first architecture, open-source components, and compatibility with existing tools (VS Code, grep, Git, Obsidian). Users can choose models, host their own services, and run AI locally, with tools designed to interact directly with the same memory across apps.
Who it’s for: Knowledge workers, developers, and power users who want a local-first, open-source, text/SQLite-based workspace to manage notes, transcripts, and AI workflows without cloud lock-in.
Active development with GitHub repository; community engagement via Discord; multiple apps and tools in active development; MIT-licensed open-source project; mentions of ongoing tooling and local-model support.
At 18, I taught myself to code while studying ethics, politics, and economics at Yale. Since then, I’ve averaged ~10k commits/year and worked at three YC startups. I wrote my 65-page senior thesis on open-source governance and digital platforms. I care deeply about data ownership, open-source, and interdisciplinary thinking. https://github.com/braden-w/ I build tools to help automate the boring parts of my writing. Hopefully, something good comes from it!
A shared workspace for everything you think, write, and build.
Epicenter launches an open-source, local-first suite of tools, centered on a single memory stored in a folder, including a text editor, CRM, personal assistant, and more. It aims to keep tools interconnected to support interdisciplinary work and preserve data ownership, with epicenter.sh as the first product—a local-first assistant built around plain-text data.
A shared context layer for you, your team, and your agents.
The notebook that thinks with you.
