What it does

Built for technical documentation

Biel combines answers for readers with a question log for the people who maintain the docs.

i.

Understands technical content

Biel indexes OpenAPI specs, code blocks, configuration examples, and error messages alongside the rest of your documentation.

ii.

Answers the question users ask

A reader may ask “Why am I getting a 401?” even when the relevant page is called “Authentication lifecycle.” Biel finds the connection and links back to the source.

iii.

Turns gaps into a writing backlog

See the questions Biel could not answer, group them by topic, and use the demand to decide what to document next.

Who it’s for

For teams that own the docs experience

Biel is designed for the people responsible for documentation quality and adoption: technical writers, docs engineers, DevRel teams, and support teams.

It is not a lead-generation chatbot or a replacement for a site without substantial documentation.

  • iCustomers rely on your docs to adopt and use the product.
  • iiSupport answers questions that the docs already cover.
  • iiiYour guides, API reference, and knowledge base live in different places.
  • ivA wrong technical answer can cost a reader hours.
  • vYou want a self-serve product, not a custom RAG project.
