The AI phone assistant that only says what's on your website
The anicall.io inbound agent answers calls around the clock, answers factual questions exclusively with content from your website, your documents and your answer catalog, and books appointments straight into your calendar.

How the knowledge boundary works
With the “grounded only” level, the anicall.io agent answers factual questions exclusively from your website, your documents and your answer catalog – anything not covered there becomes a knowledge gap for you to approve.
Import your knowledge
Your website (multi-page crawl), PDF, DOCX and text files, YouTube, RSS and your answer catalog form the agent's knowledge base.
Answer only what's grounded
Before every answer, anicall looks for matching sources. If there are none, the agent says so honestly and offers a callback – instead of guessing.
Review after the call
A second model checks every answer against the sources: green = grounded, yellow = question left open, red = unsupported claim.
Approve the knowledge gap
Open questions show up as knowledge gaps in your dashboard. Your approved answer is available as a source from the next call on.
More levels per agent: strict, balanced, open.
Four levels of the knowledge boundary
Per agent, you decide how closely it sticks to its knowledge: grounded only, strict, balanced or open.
Grounded only
Factual questions only with content from website, documents and answer catalog. If knowledge is missing, the agent offers a callback and the question becomes a knowledge gap.
Strict
The agent sticks to its approved tasks and clearly declines other topics.
Balanced
A little small talk is fine, then the agent steers back to its core tasks.
Open
The agent also answers questions outside its core tasks.
Where the agent gets its knowledge
An anicall agent's knowledge base consists of your website, uploaded documents, YouTube and RSS sources, and your approved answer catalog.
Website
Multi-page import of your website – services, opening hours, prices, FAQ.
Documents
PDF, DOCX and text files such as price lists, service descriptions or house rules.
YouTube & RSS
Video transcripts and content from feeds such as your blog or newsroom.
Answer catalog
Your approved answers to knowledge gaps – available as a source from the next call on.
Appointments straight into your calendar
During the call, the agent checks free slots and books appointments in Google Calendar, Microsoft 365, CalDAV or Calendly.
Google Calendar
Connect with your Google sign-in; free slots and bookings directly in the selected calendar.
Microsoft 365
Outlook calendars via your Microsoft account.
CalDAV
For calendars that support the open CalDAV standard.
Calendly
The agent uses the times of your Calendly event type and books there. Requires a paid Calendly plan.
Transfer, callback and analysis
If a caller wants to speak to a human, the agent transfers live or takes a callback request.
Live transfer
Set a transfer number per agent; on request the agent transfers the call live.
Callback request
If nobody is available, the agent takes a callback request – including the callback.requested webhook.
Parallel calls
Several calls at once instead of a busy signal.
Transcript & summary
Every call is transcribed, summarized and stored searchably in your dashboard.
Frequently asked questions
Does the AI phone assistant make up answers?
With the “grounded only” level, the agent answers factual questions only with content from your knowledge base. If it finds no source, it says so and offers a callback. After the call, a second model checks every answer against the sources and shows the result as a traffic light.
What happens to questions the agent couldn't answer?
They show up as knowledge gaps in your dashboard; identical questions are counted together. You answer or dismiss them; approved answers go into the answer catalog and apply from the next call on.
Which calendars are supported?
Google Calendar, Microsoft 365, CalDAV and Calendly. Calendly requires a paid Calendly plan because booking runs through the Calendly Scheduling API.
Can I test the agent first?
Yes. On the free plan with 60 minutes you can create an agent, import your website and make test calls without a credit card.
Try it with your own website
On the free plan you import your website, make a test call and see in the review which answers were grounded.
