Developer documentation
For docs your engineers actually read
API references, SDK guides, OpenAPI specs, configuration reference. Users ask “how do I authenticate,” “why am I getting a 401,” “how do I paginate” and get answers in code, with sources.

What it does
Less of a chatbot, more of a docs assistant
Generic chat widgets answer with whatever the model has memorized. Ask AI is grounded in your documentation and only your documentation, so users get answers that match what you’ve actually written.
i.
Source-linked, every time
Every answer cites the pages it pulled from. Users can click through to verify, dig deeper, or share the link. No black-box answers, no untraceable claims.
ii.
Knows when it doesn't know
If your docs don't cover a question, the bot says so and offers handoff to your support team or ticket form. Better than confidently wrong.
iii.
Reads code as code
Code blocks, config snippets, error messages, and API references are parsed as structured content. Answers come back with working examples, not paraphrases of the docs.
iv.
Speaks your users' languages
Reads English docs, answers in Spanish, French, Japanese, Portuguese, German, and 30+ more. Your users ask the way they think; Biel maps it to your content.
v.
Customizable down to the button
Your colors, your fonts, your tone of voice. Configure how the assistant introduces itself, what it can and can't say, and which pages it should prioritize.
vi.
Stays in sync with your docs
Re-index on a schedule, on every push, or via webhook. Whenever your documentation updates, the assistant updates with it. No stale answers, no manual reload.

</biel-button>Use cases
Four places teams put Ask AI
The widget drops into your docs site. Native Slack and Discord apps put the same engine into your team’s chat. Same install, same answers, wherever your users actually are.
Help center
For self-serve customer support
Replace the long FAQ page nobody reads. Users ask in plain language, get the right answer the first time, and only escalate to a human ticket when the docs genuinely don't cover it.
Slack & Discord native apps
Where your team already talks
One-click install. Mention the bot in any channel and it answers from your indexed docs, with sources cited. Replaces the constant pinging of whoever happens to know the answer that day.
Internal knowledge base
For onboarding and team lookup
Wire Biel up to your Confluence, Notion, or Google Drive. New hires learn the deploy pipeline. GTM finds the latest pricing. Without anyone repeating themselves on a Tuesday afternoon.
“Easy to set up, yet the positive effects are felt immediately.”

Questions teams ask before signing up
How long does the install actually take?
For most teams, under 15 minutes from signup to live widget. Add your docs URL, wait for indexing (5 to 10 minutes for typical docs sites), copy the snippet onto your site, ship.
What happens when Biel doesn't know the answer?
It says so explicitly and offers a handoff: a contact form, a support email, or escalation to a human agent. Configurable per project. Better than a confidently wrong answer that erodes trust.
Can I control what the assistant says about my product?
Yes. Custom system prompts let you set tone of voice, define what's in scope, and add safety rails. You can also boost specific docs (the official guide over the community thread) and exclude pages entirely.
Does the widget look like every other chatbot?
Only if you want it to. Customize colors, button shape, position, header text, placeholder copy, dark or light theme. White-label options available on higher plans.
Where is data stored?
EU data centers. GDPR compliant. Conversations are never used to train AI models. You own your data and can export or delete at any time.
Does it work with private docs behind a login?
Yes. Setup depends on how your authentication works (SSO, basic auth, custom headers, IP allowlist). Book a demo and we'll walk through the options for your stack.
