# AI chat

> Workspace-aware AI with explicit context.

ThinkEx AI chat is scoped to a workspace. It can reason about selected workspace context, inspect workspace items through tool calls, search the web when configured, and run private Python code in a Cloudflare Sandbox.

## Context Is Explicit

The intended workflow is to select the item, document passage, PDF region, or source material you want the AI to use, then ask your question. That keeps the model grounded in visible workspace context instead of relying on opaque retrieval.

## Tools

The AI tool surface is intentionally named and bounded:

<AccordionGroup>
  <Accordion title="Workspace tools">
    Search, read, create, and update workspace content through workspace access checks and `WorkspaceKernel` commands.
  </Accordion>

  <Accordion title="Web tools">
    Search the public web, read rendered pages as Markdown, and extract links through policy-checked public HTTP(S) URLs. For interactive sites, the AI can open a task-scoped Browser Run session that appears in the chat.
  </Accordion>

  <Accordion title="Interactive browser">
    Watch the active browser from the chat, expand its Live View, or take control when the AI asks for login, MFA, CAPTCHA, private input, or confirmation of a consequential action. Select **Done** or **Failed** to hand the same session back to the AI. The unrecorded session remains available briefly after the response so you can inspect it, then expires after inactivity; select **Stop** to discard it immediately.
  </Accordion>

  <Accordion title="Research tools">
    Discover and deepen research sources when the workspace task needs external literature or source discovery.
  </Accordion>

  <Accordion title="Compute">
    Run private Python code for calculations, tables, charts, and data analysis in a per-thread Cloudflare Sandbox.
  </Accordion>

  <Accordion title="Time">
    Use explicit time helpers when responses need concrete dates or current timestamps.
  </Accordion>
</AccordionGroup>

## Threads

Each chat thread belongs to a workspace and a user. Multiple threads can exist in one workspace so separate lines of inquiry do not need to share one transcript.

## Optional Services

AI behavior depends on configured services. For local development, missing optional secrets do not stop the app from booting, but the feature that needs that secret will fail or stay disabled when invoked. See [environment](/configuration/environment).
