The support workspace built for shipping products, not managing tickets

A grounded support widget, a shared inbox built for founders, and flexible guidance rules. Everything you need to keep customers happy without buying a heavyweight tool you don't need.

Start with a 7-day trial. Paid plans start at $29/month.

Source-backed replies, zero hallucinations

The AI only answers using the knowledge you provide. It cites source URLs inline, so customers see exactly where the information came from.

A calm inbox for complex cases

When a conversation requires human judgment, the AI seamlessly hands it off. Review drafts, write private notes, and reply in a click.

Custom guidance & guardrails

Tell the AI how to behave on pricing exceptions, billing disputes, and security queries. You dictate when to answer and when to escalate.

Granular gap analysis & analytics

Track where the AI succeeded and see exactly where knowledge gaps remain. Improve your agent continuously based on real user queries.

From raw docs to live AI support in four simple steps

No high-priced consultants, no complex routing trees, and no six-month implementation plans. Just complete, simple control over how AI represents your product.

1

Sync your docs in 1 click

Connect your website URL, help center, or PDFs. The AI instantly trains on your actual product knowledge—no manual data entry required.

2

Set custom escalation rules

Define exactly how the agent handles pricing exceptions, refunds, and security. Tell it what to answer, and what to pass directly to a human.

3

Embed the widget in minutes

Paste a single script tag into your site or app. The widget goes live immediately, answering repetitive customer questions 24/7.

4

Review handoffs & improve

Every conversation the AI cannot resolve lands in your inbox with source citations. Review them daily to close knowledge gaps in one click.

Every complex case lands in one calm inbox

No constant notifications interrupting your work. Every AI handoff, refund request, and billing exception collects in a single, focused dashboard. Review it once a day, approve source-backed drafts in one tap, and get back to shipping.
