Eris

Eris is a standalone Rust application that runs a local LLM as a personal agent over your Markdown vault. It reads, writes, and remembers across sessions using tiered semantic memory, while keeping all data on your machine—nothing leaves unless you explicitly opt in. The agent manages 63+ tools through token-level GBNF grammar enforcement rather than cloud APIs, ensuring reliable output from smaller models.

Designed for users who want full control over their notes and agent interactions, Eris works with Obsidian-compatible vaults and offers three interfaces: a terminal UI, a localhost web console, and an optional Discord integration. The maker built it with Cursor to create a deterministic, inspectable agent loop where drafts and vault chaos stay private by default.
