Eidetic Works Pro ships persistent memory for AI coding agents at $29/mo
Nucleus OS launched Eidetic Works Pro, a paid tier adding managed cross-session memory sync for AI coding agents like Claude Code and Cursor, priced at $29/$99/$299 per month for 1, 3, and 10 seats respectively.
Score breakdown
The release introduces a user-owned, local-first memory layer that persists AI agent context across sessions and tools, directly addressing the session-reset limitation that causes repeated re-explanation of architectural decisions in tools like Claude Code and Cursor.
- 01Pro tier is priced at $29/mo (1 seat), $99/mo (3 seats), and $299/mo (10 seats)
- 02`nucleus_ask` is the MCP tool agents use to query the shared engram store across sessions and machines
- 03Engrams are stored locally in SQLite and synced to the user's own Cloudflare R2 bucket — Nucleus OS holds no user data
Nucleus OS has shipped the Pro billing tier for Eidetic Works, targeting developers who run AI coding tools like Claude Code, Cursor, or Windsurf daily and lose architectural context when sessions reset. The post frames this as the "context-drift problem" — not a model failure, but a structural gap where each new session starts cold. The solution is `nucleus_ask`, an MCP primitive that agents call to query a shared engram store, pulling structured context that persists across sessions, tools, and machines. The underlying engram data lives in SQLite on the user's local machine; Pro adds managed sync to a Cloudflare R2 bucket using the user's own API keys, meaning Nucleus OS holds none of the data. A customer dashboard provides sync health, engram counts, and last-seen surfaces. A "60-second restore" feature is also included, allowing a full engram history to be recovered on a new machine with a single command.
The post explicitly targets small teams where members use different AI tools — for example, one person on Claude Code and another on Cursor — who need shared context.
The three tiers are: Pro at $29/mo for a single seat (managed sync, `nucleus_ask` recall, dashboard, email support), Pro+ at $99/mo for 3 seats with a team-shared engram store, and Team at $299/mo for 10 seats with priority support. The post explicitly targets small teams where members use different AI tools — for example, one person on Claude Code and another on Cursor — who need shared context. The underlying package, `nucleus-mcp 1.13.2`, is live on PyPI and includes `nucleus_ask`, `recall_activity`, and `recent_engrams`. The engram format is open SQLite and exportable as NDJSON at any time via `GET /export`. The post describes the local-first, user-owned-data design as a non-negotiable constraint rather than a marketing differentiator.
