    About Epicenter

    Epicenter: A Database for Your Mind

    Epicenter is a database for your mind built on plain text and SQLite, creating a shared context across all your applications. It allows your transcripts to inform your notes and your notes to guide your AI, with everything connected through a single folder. The platform is 100% open source and local-first by default, ensuring you own your data.

    Core Philosophy

    • Own your data: Everything lives as files on your disk. You can delete the app and keep your work.
    • Use any model: Works with OpenAI, Anthropic, and local LLMs. It's your choice and your API key.
    • Preserve authenticity: Provides a direct connection to your tools and models with no middleman.
    • Free and open source: The code can be audited, forked, and modified.
    • Blazing fast: Built with Rust, Svelte 5, and optimized for performance.
    • Built on tomorrow's stack: Utilizes CRDTs, local-first architecture, and modern web technologies.
    • Local-first by default: Your transcripts, notes, and ideas do not leave your machine unless you choose for them to.

    Tools

    • Whispering: A fast, minimal transcription tool that works with local and cloud models. It features model choice, no subscriptions, and plain text output.
    • epicenter.sh: Allows you to talk to your codebase from anywhere using your own hardware. It includes a local OpenCode instance, secure tunneling, and the ability to query from any device.

    Ecosystem & Integrations

    Epicenter's workspace, based on plain text and SQLite, is compatible with tools you already use. This allows for infinite workflows with zero lock-in. It plays nicely with:

    • Obsidian: Edit notes in your knowledge management tool.
    • grep & ripgrep: Search your entire workspace with fast Unix tools.
    • Git: Version control your ideas, notes, and transcriptions.
    • VS Code: Open any file in your preferred code editor.
    • Claude & OpenCode: Supercharge your workflow with AI that understands your context.

    Getting Started

    Epicenter is built as an alternative to apps that fragment thinking across multiple cloud services. It is designed for people who read deeply, write to think, and build to understand. Every tool is open source, your data stays in plain files you control, and you can choose your own models, host your own services, or run everything locally.
