What Epicenter does
Epicenter offers an open, portable alternative to ChatGPT's memory feature. It is an ecosystem of open-source, local-first apps that share a single memory, storing notes, transcripts, and chat histories as plain text and SQLite in one folder you control, rather than locking that data inside a single proprietary product.
Key capabilities
- A shared memory stored as plain text and SQLite that multiple tools can read and write
- Open and portable data you can grep, open in tools like Obsidian, and host wherever you choose
- Local-first, open-source apps; Whispering is the first app built on the shared memory
- A model-agnostic approach so you can choose your own AI models
Who it's for
Epicenter targets users who want to own their AI memory and data and use it across applications instead of being tied to one platform's siloed memory. The project was founded in 2025 and is based in San Francisco.
