Apply the same policy to every answer.
Connect approved sources, define which users and applications can retrieve from them, and preserve that boundary across assistants, workflows, and internal apps.
AI Knowledge Base
Ground AI in the sources your company already trusts.
Katara turns approved sources into controlled, traceable knowledge so people and AI agents answer from the right context with the right permissions.
For technical teams, it is a governed retrieval layer. For business, security, and compliance teams, it is a private, reviewable source of truth for AI.
01 // One governed knowledge layer
Connect sources once. Keep context and access together.
Make AI use the right knowledge.
Teams get answers from approved, reviewable material—not the nearest file or an ownerless knowledge collection.
02 // How it works
A Brain turns approved sources into a living, governed wiki.
A Brain is a specialized knowledge agent that maintains a reference wiki from your organization’s filtered corpus. Every refresh creates a traceable revision; audience, publication, scheduling, export, and lifecycle stay under explicit control.
01Approved sourcesDocuments, repositories, and systems inside the defined scope.
02Governed BrainGenerates and maintains a versioned wiki with audience and approval controls.
03Traceable answerAccess is checked and every answer pins its own snapshot.
01 / Organize
Create a Brain for each knowledge domain.
Organize knowledge by team or domain from one view. See each Brain’s name, kind, your role, and last update before opening its workspace.
02 / Sources
Bring each Brain’s original sources together.
Upload and search files within the Brain, with uploader attribution where reported. Upload acceptance, indexing, wiki inclusion, and export freshness are separate states; refreshing the list does not prove every file is searchable.
03 / Review
Read generated knowledge as a versioned wiki.
The local wiki organizes pages and tags for human navigation while each view exposes the commit behind it. The result stays easy to read without losing the exact snapshot under review.
04 / Control
Manage access, scheduling, and lifecycle.
See the Brain’s identity, kind, and owner alongside sharing, refresh scheduling, and GitHub export. Settings keep these actions explicit, with advanced and lifecycle controls separated.
05 / Share the Brain
Share the Brain with people and groups.
Grant viewer or editor access to organization members and groups. Whole-Brain grants cover its sources and knowledge; direct and inherited grants are additive, so removing one may leave other access in place.
06 / Share a source
Keep document access distinct from Brain access.
Review the Brain owner, inherited access, and additional viewers for an individual source. Document access does not grant Brain access, and removing a direct grant may leave inherited access in place.
07 / Answer
Connect Q&A agents to fixed evidence.
A Q&A agent can bind to a Brain combining original sources and committed wiki. The saved binding is fixed; Katara checks availability and access for every answer, with no automatic fallback and independently enforced agent and Brain permissions.
03 // Why teams use it
Better answers without ungoverned knowledge sprawl.
Restrict generation and retrieval to material inside the defined scope.
Keep audience and permissions attached to the Brain and each agent.
Identify the exact snapshot behind a page or answer.
Control approval, refresh, export, and lifecycle from one place.
