EIDARA is open-source, local-first context engineering for AI agent memory.
One compiled markdown brain that Claude, GPT, and DeepSeek all read and write — through MCP.
Governed by a constitution, maintained by an autonomous curator. Yours forever. No cloud, no lock-in.
Every AI session starts from scratch. You explain the same project twice. You repeat decisions you made three conversations ago. You waste tokens keeping context alive in threads that should have ended hours ago.
Your AI is powerful. But without memory, you're doing the remembering for it.
Your AI saves knowledge to local files. A script organizes them. Next session, any AI reads everything.
Your AI writes what matters —
decisions, context, preferences —
one topic per file.
A local script validates,
cleans, and organizes
everything automatically.
Any AI opens one file
and instantly knows
your full context.
Save once. Available everywhere.
No terminal commands. No file management. Two phrases are all you need.
→ To recall context
"Check EIDARA for context on project X."
Seconds later, the AI knows everything —
even if it's never seen this project before.
→ To save something new
"Save this decision to EIDARA."
The AI writes it. Next session —
on any platform — it's there.
Claude, GPT, DeepSeek, Gemini — any model that reads text. Switch between them mid-project. Your context follows. No lock-in, no integrations to configure.
Your files stay on your computer. No cloud account, no API keys, no telemetry, no data leaving your machine. Just markdown files and a Python script.
A compiler validates every entry, removes duplicates, fixes formatting errors, and creates a verified snapshot. You never manually clean up your memory.
When an AI spots an error — outdated info, wrong format, broken reference — it fixes it automatically. The system gets better with every interaction.
52 real-world scenarios across 4 AI models — remembering project decisions,
recalling preferences, handling updates, resolving conflicts. No cherry-picking.
Check the ones that apply.
Download EIDARA. Give the INSTALL file to your AI. It handles everything —
personalization, setup, first compile. You don't type a single terminal command.
