Knowledge base

Answers from your docs, not guesses.

Upload PDFs, slides, spreadsheets and web pages, then connect them to your agent with a knowledge sub-agent. It searches your library before it answers, in chat and in voice.

How it works

From upload to grounded answers

  1. 01

    Add your sources

    Upload PDF, Word, PowerPoint, Excel, CSV or Markdown files, import a web page by URL, or write a page yourself.

  2. 02

    Organise by topic

    Keep billing, shipping and product content in separate knowledge bases, each made of articles.

  3. 03

    Connect a sub-agent

    Create a sub-agent with the knowledge base tool, pick which knowledge base it reads, and add it to your agent.

  4. 04

    Improve from gaps

    After each conversation, questions the agent couldn't answer from your docs are listed as knowledge gaps.

Capabilities

Built for support that stays on-policy

A knowledge base is only useful if the agent reaches for it before it improvises.

Files, pages and your own writing

Bring help-centre pages, handbooks, price lists and product sheets into one searchable library.

Connected through a sub-agent

The main agent hands questions to a knowledge sub-agent, so it stays focused on the conversation.

Search by meaning

Questions match on meaning, not exact words, so “can I send it back?” finds your returns policy.

Chat and voice

The same sub-agent and library serve website chat and browser voice calls, so you maintain content once.

Edit in place

Fix a paragraph in the built-in editor and save. Only the sections you changed are re-indexed.

Private to your organisation

Each organisation's knowledge lives in its own database, never mixed with anyone else's.

In practice

When a knowledge base pays off

These are the moments teams stop relying on answers buried in Slack threads.

Deflect repeat FAQs

Shipping times, return windows, plan limits — answered from your docs every time.

Onboard without a human

New buyers get setup steps from your guides instead of waiting on email.

Keep policy consistent

Every answer comes from the same rules your team already approved.

Close the content loop

Knowledge gaps from conversation intelligence tell you what to write next.

How it connects

Your agent reads your docs through a sub-agent.

A knowledge base isn't attached to the agent directly. You give a sub-agent the knowledge base tool, point it at one knowledge base, and add that sub-agent to your agent. The main agent stays focused on the conversation and calls the sub-agent whenever it needs facts.

  1. Main agent

    Talks to the visitor in website chat or browser voice and decides when it needs facts.

  2. Knowledge sub-agent

    Has the knowledge base tool, searches your library and hands back what it found.

  3. Knowledge base

    Your articles, split into short sections and indexed by meaning.

One library per job

Each knowledge sub-agent reads one knowledge base. Give your support agent the help-centre library and your sales agent the pricing and product library.

Same path in chat and voice

Website chat and browser voice both call the same sub-agent, so an answer on a call matches the answer in chat.

Supported sources

What you can add

Everything is split into short sections of about 1,000 characters and indexed by meaning, so the agent retrieves just the passage it needs.

Upload files

Text-based files are converted in your browser and split into sections.

  • PDF
  • DOC
  • DOCX
  • ODT
  • RTF
  • EPUB
  • PPT
  • PPTX
  • XLSX
  • CSV
  • TXT
  • MD

Import a web page

Paste a URL. Embage strips navigation, headers and footers and keeps the page text. One page per import.

Write it yourself

Add a page in the built-in Markdown editor for answers that don't live in a document yet.

Scanned, image-only PDFs and password-protected files can't be read. Export them as text first.

Limits

Knowledge base limits by plan

An article is one source, like a PDF or a web page. A page is one short section of it. Every lookup by the sub-agent counts as one search.

FAQ

Questions

How does the knowledge base connect to my agent?

Through a sub-agent. Create a sub-agent, give it the knowledge base tool, choose which knowledge base it searches, and add it to your main agent. When a visitor asks something your docs cover, the main agent calls the sub-agent and answers from what it returns.

What can I upload?

PDF, Word (.doc, .docx, .odt, .rtf), EPUB, PowerPoint (.ppt, .pptx), Excel (.xlsx), CSV, text and Markdown files, plus web pages by URL. Files need real text: scanned, image-only PDFs and password-protected files can't be read.

Can I train a chatbot on my website?

Yes. Paste a page URL and Embage imports its text, leaving out navigation, headers and footers. Each import brings in one page, so start with the pages customers ask about most: pricing, shipping, returns and FAQs.

Is this retrieval-augmented generation (RAG)?

Yes. Embage splits your content into short sections, turns them into embeddings and retrieves the closest matches before the model answers. You get RAG without setting up a vector database or writing code.

What happens when my docs don't cover a question?

The agent works from the closest matches in your library. After the conversation, questions it couldn't answer from your knowledge base are listed as knowledge gaps, so you know what to add.

Do chat and voice share the same knowledge?

Yes. Website chat and browser voice call the same sub-agents, so one library serves both. Telegram agents don't search the knowledge base yet.

How do updates reach live conversations?

Edit a page and save — new searches use the change right away, with no agent to redeploy. Imported web pages don't refresh on their own, so re-import a URL when that page changes.

Can different agents use different libraries?

Yes. Each knowledge sub-agent is set to one knowledge base, so your support agent and your sales agent can read different sources.

How much content can I add?

It depends on your plan: Free includes 1 knowledge base, 10 articles, 50 pages and 200 searches a month; Starter 3, 30, 100 and 1,000; Pro 20, 500, 5,000 and 1,500. Enterprise is scoped with you.
