No cloud, no servers, no sync unless you ask for it.\n\n**ENCRYPTED ALWAYS** - AES-256-GCM. Keys never leave your device. 24-word recovery phrase, like a crypto wallet.\n\n**ZERO-KNOWLEDGE SYNC** - Need multi-device? Opt-in sync encrypts everything client-side. We only see ciphertext. Like Signal, but for AI memory.\n\n**OPEN SOURCE** - Don't trust us. Verify. Audit the code. Self-host if you want. Fork if we disappear.\n\nWorks with Claude Desktop, Claude Code, Cursor, and any MCP-compatible client.\n\n## Quick Start\n\n```bash\nnpx engram-core init\n```\n\nRestart your AI client. It remembers you now.\n\n\u003cp align=\"center\"\u003e\n  \u003cimg src=\"assets/demo.gif\" alt=\"Engram Demo\" width=\"100%\"\u003e\n\u003c/p\u003e\n\n## Features\n\n| Feature | Description |\n|---------|-------------|\n| **Local by Default** | Your data stays on your device.

No custom cryptography.\n\n| Layer | Algorithm |\n|-------|-----------|\n| At Rest | AES-256-GCM |\n| Key Derivation | PBKDF2-SHA256 (600k iterations) |\n| Search Index | HMAC-SHA256 (blind indexing) |\n| Recovery | BIP39 Mnemonic (24 words) |\n\n## Why Not Cloud Memory?\n\n|                     | Engram | Cloud Memory |\n|---------------------|:------:|:------------:|\n| Where's your data?  | Your device (default) | Their servers |\n| Who holds the keys? | You | They do |\n| Can they read it?   | No | Yes |\n| Can you verify?     | Yes (open source) | No |\n| Cross-app           | Any MCP client | Locked to one app |\n\n## Philosophy\n\nThe AI industry solved intelligence. It forgot about sovereignty.\n\n- Memory is infrastructure, not a feature\n- Encryption is a right, not a premium tier\n- If you can't export it, you don't own it\n\n## Claude Code Agent Teams Integration\n\nEngram integrates with Claude Code Agent Teams through lifecycle hooks. When teams complete tasks or wind down, Engram can automatically consolidate team memories into structured summaries.\n\n**How it works:**\n- Agents save memories tagged with `team:\u003cname\u003e` during work\n- Hooks trigger `engram consolidate` at key moments (task completion, teammate idle)\n- Consolidation categorizes memories into findings, decisions, hypotheses, blockers, and action items\n- Summaries are saved as searchable `team-summary` memories for future sessions\n\n**Configuration** (`.claude/settings.json`):\n\n```json\n{\n  \"hooks\": {\n    \"TaskCompleted\": [\n      \"engram consolidate\"\n    ],\n    \"TeammateIdle\": [\n      \"engram consolidate\"\n    ]\n  }\n}\n```\n\nYou can also run `engram consolidate` manually to generate team summaries on demand.\n\n---\n\n\u003cp align=\"center\"\u003e\n\u003cstrong\u003eYour AI should remember you.
