Grounded by design

Uncertainty is not disguised as an answer.

Deyo is designed to rely on registered knowledge. Questions that require an account check, an external action, or missing evidence can be declined or handed to a person.

Fixed safety instructions

Evidence-first behavior and prompt-injection defenses cannot be overridden by users.

Workspace isolation

Sources, conversations, and usage are separated by workspace.

Request and answer limits

Allowed origins, rate limits, and daily AI-answer limits protect the widget.

Real human handoff

Handoff copy changes only when the conversation actually reaches the Inbox state.

Pricing

Verify quality before you scale.

Start without a card. Upgrade only when your team needs more conversations, sources, or model choice.

Questions before you start

Can Free hand conversations to a person?+

Yes. Inbox, human handoff, and configured Slack or email notifications are available. Conversation and knowledge limits vary by plan.

Which files can Deyo learn from?+

Deyo currently accepts PDF, Markdown, TXT, JSON, JSONL, and CSV. Image-only scanned PDFs need OCR before upload.

What happens when Deyo does not know?+

It should not invent an answer. It can explain that it lacks evidence and keep the same conversation for a teammate.

Does Deyo perform refunds or account changes?+

No. Deyo can explain registered policies, but actions that change a customer's account belong with an authorized teammate.
