Organize, version, and serve project context to any LLM — from Claude Code to Cursor to ChatGPT.
Every AI coding tool starts each session with amnesia. Your architecture decisions, naming conventions, and deployment quirks — none of it carries over. You re-explain the same context with the same tools every single day.
The common workarounds are CLAUDE.md files, .cursorrules, AGENTS.md — each tool with its own configuration format. You end up duplicating knowledge across multiple places. They drift apart. Your Claude Code config says one thing; your Cursor rules say another.
Recuerd0 is a dedicated knowledge base for managing the context your AI tools consume. You curate project knowledge once and serve it to every tool via REST API.
How it works
Workspaces group knowledge by project or domain. Backend conventions in one workspace, frontend patterns in another, org-wide standards in a shared workspace.
Memories are versioned markdown documents with titles, tags, and full history. When conventions evolve, you create a new version — like Git for context. Branch from any version, track how decisions changed, and never lose the rationale.
Access is through a REST API with Bearer token authentication. Any tool that can make an HTTP request reads from the same source. There’s also a CLI for terminal workflows and a Claude Code plugin for tighter integration.
Search uses the database’s full-text search with millisecond performance. No embeddings, no vector database, no RAG pipeline. The agent decides what to search for and how to refine the search. The index updates on every write, is deterministic, and requires zero infrastructure beyond the database.
Architecture decisions
Human-curated, not auto-captured. Automatic knowledge capture sounds appealing, but it produces noisy results — context-specific fixes that don’t generalize, contradictory items as conventions evolve. The human decides what’s worth persisting. The team reviews and evolves it.
Tool-agnostic by design. We built an API, not a plugin for one tool. Your knowledge base survives any tool change. Claude Code, Cursor, ChatGPT, Windsurf, custom scripts, CI/CD pipelines — same context, same source.
Small and focused. Recuerd0 is designed for a small set of focused memories per workspace philosophy, not thousands of files. The constraint forces curation. When the workspace is focused, the right answer is obvious without sophisticated search algorithms.
Pricing
Recuerd0 SaaS is $15/month for up to 10 users. Managed hosting, automatic backups, updates, and email support. Create an account and start in minutes at recuerd0.ai.
Teams of 6 or more can contact us for custom plans.
Self-hosted is available under the OSASSY license — the same model 37signals uses for Fizzy. It’s essentially MIT with one addition: you can’t take the code and offer it as a competing hosted service. Deploy on your server, modify the code, use it internally — free forever.
The self-hosted version is not available at launch, but it will be available pretty soon.
Get started
The API documentation covers every endpoint. The CLI reference has installation and commands. The agent workflows guide shows how to integrate with Claude Code, Cursor, and other tools.
Context engineering has become a core developer skill. It deserves a dedicated tool.
