A knowledge base is a set of documents a Persona can read when it answers. Open one from Library: click Knowledge bases, then click the knowledge base. Its page opens on Overview.

Add documents

Click Add files, check the list on Documents, then Start Ingestion.

Search indexed text

Use Search to find the passages a chat would cite.

Suggest prompts

Add prompts that appear on home when a chat targets this knowledge base.

Manage the base

Rename it, rebuild its knowledge graph, change the embedding model, or delete it.

​
Open a knowledge base

1

Open Library

Click Library in the left sidebar.
2

Open Knowledge bases

Click Knowledge bases. Each row shows the name and how many documents it holds.
3

Open one

Click a knowledge base. The breadcrumb shows Library, Knowledge bases, then its name. The page opens on Overview.
Overview shows service status, the newest documents, and suggested prompts. Use Documents, Search, and Suggested Prompts in the tab bar. Open More when you need Data Studio or Settings.

​
Add and ingest documents

1

Choose files

Click Add files and pick one or more files. They wait on Documents so you can check them.
2

Start ingestion

Click Start Ingestion to index them, or Cancel to drop the staged files.
3

Wait for indexing

Each document joins the list once indexing finishes. A Persona that reads this knowledge base can then use those documents when it answers.
Supported types include .txt, .md, .html, .htm, .csv, .docx, .pdf, .json, .xml, .log, and .rst. Legacy .doc files are not supported. The header shows how many documents you have out of 2,000.

​
Create a knowledge base

You create a knowledge base from a Persona, not from Library.
1

Create one while you make a Persona

Click Personas, then New persona. On the frame that asks what it needs for the job, add the files it should read. See Create a Persona.
2

Or add documents on an existing Persona

Open the Persona, click Knowledge base, then Add document. The first time, webAI makes a knowledge base named after the Persona and attaches it. See Manage documents.
3

Open it in Library

That knowledge base then appears under Library → Knowledge bases, where you can add more files and use Search, Suggested Prompts, Settings, and the other tabs on this page.
Click Search. Type a query and run the search. Results show the file name, chunk number, match score, and a short preview. Click a result to open the citation preview. Search finds indexed passages in this knowledge base. To ask a Persona that uses these documents in a full chat, open that Persona or chat with it from Home.

​
Suggested prompts

Click Suggested Prompts, or click Manage under Suggested Prompts on Overview.
1

Add a prompt

Click Add prompt. Enter a Question. Optionally add an Expected answer to spot-check retrieval.
2

Save as you type

Edits save as you type. You can hold up to 32 prompts.
Prompts appear on home when a chat targets this knowledge base. You can also Import from JSON if you already have a list of questions.

​
Rebuild the knowledge graph

After at least one document is ingested, open the options menu on the knowledge base and choose Build knowledge graph or Rebuild knowledge graph. A rebuild discards the current themes, entities, and summaries, then builds them again from the documents. Whole-collection answers are unavailable until the rebuild finishes. Confirm Rebuild when asked. If a build is already running, the menu offers Restart knowledge graph build.

​
Settings

Open Settings from the tab bar or More. Before the first ingestion, choose Ingestion Mode:
  • Text-only: Extract and embed text. Recommended for most documents.
  • Multimodal: Extract page images, tables, and figures from PDF and DOCX files.
You can also set chunking options before the first ingestion. After documents are ingested, those settings are locked and show as read-only values for this knowledge base.

​
Data Studio

Open Data Studio from the tab bar or More. Collection Statistics shows Points, Vectors, Indexed, Status, and Segments. Click Refresh to update them. Chunks lists indexed passages with their file names so you can page through what was stored.

​
Rename, change the model, or delete

Open the options menu on the knowledge base.
  • Rename opens Edit Knowledge Base. Change the name, description, or icon, then click Save.
  • Click the embedding model pill on the knowledge base header when you need a different model. Confirm Drop vectors and reingest if you continue. Personas set up for the old model will no longer match this knowledge base.
  • Delete opens Delete Knowledge Base. Confirm Delete to remove the documents, embeddings, and associated data. Any active ingestions are cancelled.
A Persona’s Knowledge base tab is the quickest way to give that Persona documents. Open the Persona, click Knowledge base, then Add document. The first time, webAI makes a knowledge base named after the Persona and attaches it. That knowledge base then appears in Library. See Manage documents.

​
