Knowstory

Knowstory is an AI search bar built for developer documentation. Instead of typing keywords and hoping they match a heading, you ask a question in plain language and the assistant reads the context and returns the relevant page. It supports documentation sets including Next.js, Vite, Django, Vercel, and Terraform, with more added over time, and it is delivered as a Chrome extension so it sits inside the docs site you are already reading. The service is free to use with no registration or payment.

The problem it targets is real: documentation search is usually keyword based, and a keyword only works if you already know the name of the thing you are looking for. When you know what you want to achieve but not what it is called, keyword search fails and a plain-language question succeeds. Keeping the tool inside the browser means you do not have to leave the page to get the answer.

- Ask a question in natural language about a framework

- Get the relevant documentation page instead of a keyword list

- Work across several supported doc sets from one extension

- Avoid leaving the page to run a general web search

- Onboard onto an unfamiliar library faster

- Developers moving between multiple frameworks

- Teams onboarding onto unfamiliar documentation

- New hires reading a large docs site for the first time

- Anyone frustrated by guessing the right doc keywords

Coverage is limited to the documentation sets the tool supports, so an obscure library will not be searchable and you will still fall back to a general search. Answer quality depends on how clearly you phrase the question, and a vague prompt can return a plausible but wrong page. Because it is a free upstream tool, availability and the list of supported docs can change. Treat results as a pointer to the page you should read, not as a replacement for reading it, and verify version-specific details against your own project.
