Knowledge base builder for AI voice and chat agents
A business’s information is scattered across its website, brochures, rate cards and the notes in your head. KB Builder brings it into a knowledge base your agent answers from, with every fee, timing and rule kept with the service it belongs to. Anything missing comes back to you as a question, before a caller asks it.
Start free, no card. Works with Vapi, Retell, ElevenLabs or any platform that takes a document.
Built for every industry,
with what its callers ask
The real work
Before an agent can answer, someone has to pull it all together, and keep it together every time the business changes something. That someone is usually you.
Why knowledge bases break
A person reads a page from the top and keeps it all in mind. An agent is handed a few pieces of your document, with nothing around them, and has to answer from those alone. A knowledge base written for people breaks there.
The usual ways to build a knowledge base all write for the person:
Written for people browsing the site
Where it breaks
Written for a person to read through
Where it breaks
Written the way you'd explain it to a colleague
Where it breaks
Written for how your agent reads
What you get
Why we built it
We built a voice agent for a resort and tested it with live calls. Twice, a caller asked the price of a day package and the agent answered with another product’s price: a villa’s once, a cottage’s the next time. The model was fine. The knowledge base had a price in one place and the name of what it belonged to in another.
So we built the file differently, tested it on live calls, and then built KB Builder to write that file for any business. Here is the builder’s own run on that resort’s website.
How it works
The business's website, its brochures, rate cards and policy documents, and notes you type in. The builder reads all of it and finds everything the business sells.
You get a short list of what callers will ask that none of it answers, most important first. Answer what you know; skip the rest.
A Markdown file, ready for Vapi, Retell, ElevenLabs, Chatbase or any platform that takes a document. No setup on their side.
## IUI (one treatment cycle) at Sunrise Fertility Centre: price and what it includes
IUI: one treatment cycle, ₹12,000 per cycle, including the procedure and one follow-up scan. Whether the IUI price includes medicines has not been confirmed.
## IVF (one treatment cycle) at Sunrise Fertility Centre: price and what it includes
IVF: one treatment cycle, ₹1,20,000 per cycle, including egg retrieval, lab work and one embryo transfer.
A few lines of a file. The clinic is made up; the format is the real one.
Even when retrieval hands your agent one chunk on its own, the price still says which treatment it is for.
If the website doesn't say, the file says it hasn't been confirmed. Your agent offers to find out instead of guessing.
Every section is titled with the product and what it covers, so search inside your platform finds the right one.
Industries
Each industry has its own knowledge model: the questions callers of that kind of business ask. The builder checks the website against it and tells you what’s missing.
Room and package prices by day, check-in times, meals included, child and pet rules, cancellation.
Treatment prices and what they include, doctors, consultation fees, timings, insurance and EMI.
Unit types and prices, sizes, possession dates, amenities, site visits, loans and approvals.
Fees by grade or course, admission dates, eligibility, timings, transport and hostel.
The general model: what you sell and its price, hours, location, booking, payment and policies.
Questions
If you build voice or chat agents for businesses, you have probably said one of these.
It happened to us too, twice, on our own test calls: a caller asked the price of a day package and heard a villa's price, and later a cottage's. The cause was the knowledge base, not the model. A price sat in a chunk without the name of the product it belonged to. KB Builder writes every price and timing into a sentence that names its product, so even a chunk on its own can't be read the wrong way.
Because the platform copies the pages as they are and cuts them into chunks. Websites put prices in tables, cards and footnotes, far from the product name. And a copy can't tell you what the website never says, which is exactly what callers ask about next.
Most patches fill a gap a caller found for you. The builder finds those gaps before you go live: it works from the list of questions callers of that kind of business ask, and shows you which ones the business's website, documents and notes don't answer, most important first.
Yes. KB Builder is built for every industry. It knows what callers of clinics, real estate firms, schools, resorts and other businesses ask, checks the business's information against it, and tells you what's missing.
Any platform with a knowledge base. It is a Markdown file: Vapi, Retell AI, ElevenLabs and Botpress take it as it is; Bland AI, Synthflow and Voiceflow take it pasted as text; Bolna takes it saved as a PDF. Our platform guides show the steps for each, from each platform's own documentation.
Your first build is free, with no card, and shows you everything found and everything missing. Downloading the file needs a paid plan, from ₹1,499 or $19 a month for 3 client knowledge bases.
