What is Knowl Cloud?
Knowl Cloud is a knowledge management system that runs as an MCP server to give AI agents persistent, verifiable memory across sessions. Knowl stores facts with reasoning, evidence, and provenance locally in your repository, automatically tracking when information changes and retiring stale facts so they never silently break your agents.

Knowl Cloud pros

- Built-in history and freshness tracking; superseded facts are preserved with full lineage rather than deleted or overwritten
Knowl Cloud cons

Frequently asked questions about Knowl Cloud
How do I integrate Knowl with my AI development tools?
Knowl runs as an MCP server, so any tool that speaks MCP works with no adapter. It also has direct integrations with Claude Code, Cursor, GitHub Copilot, OpenHands, and 10+ other IDEs via `knowl init` commands.
Will my knowledge be uploaded to the cloud?
No. Knowl runs in your repository and keeps knowledge there by default. Your code, embeddings, and session history are never uploaded unless you explicitly choose to publish.
What happens when facts become outdated?
Knowl records what each fact replaced and what replaced it. Superseded knowledge is never deleted—the full history remains readable, and there is no delete verb in the product.
How is Knowl different from using a CLAUDE.md file?
Unlike static markdown files, Knowl automatically tracks when information changes, shows evidence and provenance for claims, and prevents stale information from breaking your agents mid-task.
