SharedContext

Sovereign, encrypted, portable memory for AI agents.

What Is It

SharedContext is a local-first memory layer for LLM agents. It gives Cursor, Claude Code, and Codex persistent memory that you own, synced to Arweave so it follows you across sessions and machines.

Your AI assistant forgets everything the moment a session ends. Project decisions, coding preferences, architectural context — all gone. You re-explain the same things every day.

SharedContext fixes that. It runs as an MCP server that your AI client connects to. Agents store and recall facts through MCP tools. A background watcher syncs your conversation history. Everything is encrypted client-side and uploaded to Arweave. Restore it all on a new machine with a 12-word recovery phrase.

Why Shared Context

Your AI memory is fragmented:

Cursor stores transcripts in ~/.cursor/projects/
Claude Code stores sessions in ~/.claude/projects/
Codex has its own isolated context

None of them talk to each other. None of them persist structured knowledge. None of them let you move to a new machine and pick up where you left off.

SharedContext collapses all of that into one encrypted, portable layer that every client reads from and writes to. One memory. One identity. One place to look.

What It Does

Capability	Description
Fact memory	Agents store and recall structured facts (preferences, decisions, architecture) across sessions
Conversation recall	Retrieve past conversations from any client — "continue the discussion about auth"
Encrypted sync	All data is encrypted locally with AES-256-GCM before leaving your machine
Arweave persistence	Encrypted blobs are uploaded to Arweave for permanent, censorship-resistant storage
Cross-machine restore	12-word recovery phrase reconstructs your entire context on any machine
Conversation sharing	Share a specific conversation via encrypted link — recipient imports with one command
Auto-setup	Detects installed AI clients and configures MCP automatically on `init`

What It Is Now

SharedContext is early (v0.1.x). It works, it's tested, but it's not battle-hardened yet.

Supported clients: Cursor, Claude Desktop, Claude CLI, Codex

Current limitations:

Ranking is heuristic/keyword-based, not semantic vector search
Single-user only — no collaborative memory
Not a hosted service — you run everything locally

How It Works

Identity

A 12-word recovery phrase deterministically derives a secp256k1 keypair. The phrase + a random salt derive an AES encryption key via Argon2id. The private key is stored encrypted at ~/.sharedcontext/identity.enc. The phrase is stored in the OS keychain for background MCP access.

Local Storage

SQLite is the runtime store. Three tables:

facts — structured memory (key/value with tags, scope, confidence)
pending_deletes — tombstones queued for remote sync
meta — version cursors, offsets, sync state

All reads are local. Fast and offline-capable.

Fact Sync

New or updated facts are written to SQLite with dirty=1
Background loop collects dirty facts + pending deletes
Changes are converted into shard operations (upsert / delete)
Operations are chunked to keep payload size bounde
