Answers your customers can trust — because they stay current
A voice agent is only as good as what it knows. Callender treats knowledge as a living system, not a PDF you uploaded last quarter.
Second-level sync
Change a price, a policy or an opening hour, and every channel — phone, email, chat — answers with the new version within seconds.
Learns from every interaction
Recurring questions, new phrasings and edge cases from real calls flow back into the knowledge base, so coverage grows on its own.
Structured + unstructured
Feed it documents, FAQs, spreadsheets, web pages or database records. Callender organises them into one coherent, queryable body of knowledge.
Human-in-the-loop corrections
Spot a wrong answer? Correct it once — the fix applies everywhere instantly, and the audit trail shows who changed what.
The price-change test
The classic failure: you update a price, and your bot quotes the old one for a week. Here's the same moment on Callender:
The service price changes in your source document — a spreadsheet, your admin panel, wherever it lives.
The knowledge base picks up the change, re-indexes the affected entries, and versions the old answer for the audit log.
The very next call gets the updated answer, in every language. No re-training, no redeploy, no ticket to anyone.
Frequently asked questions
What can I feed into the knowledge base?
Documents, FAQs, spreadsheets, web pages, and records from any connected data source. Content is deduplicated and organised automatically.
How fast do updates take effect?
Typically within seconds of the source changing. Every update is versioned, so you can always see what was answered when — and roll back.
Does it respect access control?
Fully. Knowledge inherits the same paragraph-level permission system — an answer is only used with callers and staff who are entitled to it.
