18,234+ people using Keen

AI coding assistants use outdated documentation. That's why they suggest code that doesn't work.

Keen connects these tools to current, accurate framework docs. It's compatible with Cursor, Cline, Windsurf, and any assistant supporting MCP.

When your AI has access to the latest documentation, you get working code instead of deprecated methods and hallucinated functions.

Without Keen

Outdated code examples based on old training data
Hallucinated APIs that don't actually exist
Missing knowledge about new features
Security issues from deprecated methods

Frequently Asked Questions

What is MCP and how does Keen work with it?

MCP (Model Context Protocol) allows AI assistants to access external tools and information. Keen connects to your AI coding assistants through MCP, feeding them real-time documentation data.

Which AI assistants are compatible with Keen?

Keen works with any AI assistant that supports MCP, including Claude, Windsurf, Cursor, Cline, and others.

Do I need to change my prompts or workflow to use Keen?

No. Keen works silently in the background, automatically enhancing your AI's knowledge without requiring any changes to how you work.

How up-to-date is the documentation?

Our system continuously monitors and parses official documentation sources, ensuring you always have access to the most current information available.

Is there a limit to how many AI assistants I can use with my API key?

No. Your Basic plan API key can be used with as many AI assistants as you need, as long as you stay within your monthly API request limit.

What happens if I exceed my API request limit?

If you approach your limit, we'll notify you by email. You can choose to upgrade to the Enterprise plan for unlimited requests or wait for your limit to reset the following month.
