Epicenter

Epicenter is a set of local first, open source applications that share one store of data on the user's own machine. That store is a single folder of plain text files and SQLite databases, so a meeting recorded in one tool can be edited in a general notes app such as Obsidian and then queried with an AI model, without exports or copying between products. Deleting an application leaves the underlying files intact. Two tools are available today. Whispering is a fast, minimal transcription app that works with local or cloud models, requires no subscription and writes plain text output. A second tool runs a local coding agent instance with secure tunneling, so a developer can talk to their codebase from any device while the compute stays on their own hardware. Underneath both sits a workspace library installed from npm that defines typed tables and key value stores backed by the same folder. The stack is built with Rust and Svelte, and the project describes its architecture as local first, using conflict free replicated data types. Everything is free and open source, and the site publishes no pricing page or paid tier. Users bring their own API keys for OpenAI, Anthropic or a local model, so running costs are whatever those providers charge directly. The code can be audited, forked and self hosted. The suite is small at this stage. More tools are listed as coming soon behind an early access form, which means a buyer today is choosing a transcription app, a codebase query tool and the shared workspace foundation rather than a broad product line.
