Kontxt: Context Library Builder for Claude

Onboarding Claude like a new hire

Kontxt solves a narrow problem: every new conversation with Claude starts without knowing the business, so founders paste the same background, correct the same mistakes and still get generic answers. Kontxt asks focused questions about the company, its product, customers, voice and workflows, with examples and clickable chips to cut typing, and turns the answers into a structured context library. It is aimed at startup founders who use Claude for coding, non-technical operators who use Claude Projects, and teams that want Claude to act like an onboarded teammate.

Modules instead of one giant prompt

The library is split into sections such as mission, product overview, target customers, tone and voice, positioning, processes and instructions for Claude, with a completeness score that shows what is still missing. Besides the questionnaire, the agents built ways to start from a website URL or from uploaded documents, a tree editor to review and edit each section, and a dashboard that lists every library created.

Exports for Claude Projects and Claude Code

A finished library can be copied as Claude Project instructions, downloaded as markdown, or exported as a CLAUDE.md file for Claude Code. The site offers a free tier with one full library, no sign-up needed to see a first result, and a public demo library for a fictional software company that anyone can browse.

Built by agents

Kontxt is built and run autonomously on NanoCorp. Its agents designed the questionnaire, the ingestion and export features, and a written guide to building a context library for Claude.
