—

Generated code through AI and couldn't figure out why it doesn't work?

—

Scared to update your framework because the AI assistant hasn't "heard" about the new version?

—

Spent hours debugging, only to find out AI made up a non‑existent API?

—

Feels like your AI assistant doesn't know about the new features in the latest framework version?

—

Sound familiar?
Then keep reading — we'll explain why this happens.

You're not alone. Research shows that up to half of the code generated by AI assistants contains errors or outdated fragments. Why does this happen? Because AI models are trained on limited and outdating data, and don't know about updates after their "knowledge cutoff date."

They continue to confidently suggest code even if it's already outdated, because they don't have direct access to fresh documentation, are trained on old library versions, and will never tell you "I don't know" – they'd rather make up an answer.

As a result: the assistant can confidently give you outdated or incorrect code, and you'll only realize it when you hit an error.

So what do you do?

Keen is a tool for developers that connects to your AI assistant and automatically finds the freshest information from official documentation with every request.

When you ask it to generate code, Keen pulls up current data for the needed libraries and frameworks – resulting in the assistant suggesting solutions based on the latest standards and without annoying errors. Current syntax, new functions, proper methods – everything is immediately accounted for in your code.

Keen integrates with AI assistants through an open protocol MCP and works in popular development environments (Cursor, VS Code+Cline, Windsurf, etc.).

You don't need to change your usual process: set up Keen once, and it will work invisibly in the background while you chat with your assistant as usual. The assistant will start giving more accurate answers without any additional effort on your part.

How it works

Just three steps — nothing complicated:

Write your request. Ask your AI assistant to generate code as you usually do — for example, ask it to create a React component or write an SQL query.

Keen finds fresh docs. At the same moment, Keen automatically pulls up current information from documentation (official manuals, latest API versions) for the corresponding libraries. Everything happens in seconds in the background.

Get working code. Your AI assistant will return ready-to-use code that accounts for the latest updates and best practices. No outdated calls, no hours of googling errors — the code works right from the start.

How your experience will change
