 - `host.plans:read` allows reading estimated execution plans for DBX's own connections (see [Estimated Execution Plans](#estimated-execution-plans)). It is read-only: it never grants SQL execution, writes, DDL, or actual plans, and it is the only plan scope that exists.
 - `host.storage` gives the workbench UI a persistent key-value store scoped to this plugin (see [Persistent UI State](#persistent-ui-state)). Values never leave the plugin's own data directory.
+- `host.ai` lets the plugin open a conversation with a data snapshot in the built-in DBX AI panel, using its model selector, history, follow-up messages, cancellation and export. Older DBX builds reject the unknown permission at install time, so plugins that must install everywhere should treat `host.ai` as optional.
 - `host.network:https://host[:port]` declares a browser-accessible HTTPS origin added to CSP `connect-src`; at most eight origins are allowed, with no paths, wildcards, or tokens. The service's CORS rules still apply. This permission is not a native Sidecar network firewall.

 Keys are strings up to 256 characters; values are capped at 256 KiB serialized and the whole store at 1 MiB — this is UI state, not a data sink. Entries live in the plugin's own `plugin-data/<id>` directory, isolated per plugin, and survive upgrades and uninstall. Bulk data, caches, and anything the sidecar produces belong in the sidecar's data directory instead (see [Native Sidecars and RPC](#native-sidecars-and-rpc)). On the web host the same API is backed by the browser profile, so identical code works in both hosts.
 
+### Analyse plugin data in DBX AI
+
+Declare `"permissions": ["host.ai"]` in the manifest, then call this from the plugin's analysis action:
+
+```js
+await dbxPlugin.ai.openConversation({
+  title: "Watchlist analysis",
+  prompt: "Compare the supplied quotes and explain risks and missing data.",
+  context: { snapshotId: "watchlist-1", quotes, source, dataTimestamp },
+  send: true,
+});
+```
+
+`title` allows 200 characters and `prompt` allows 32000. `context` must be a plain JSON object and is limited to 2 MiB. The host binds the installed plugin identity and copies the snapshot. Quote refreshes or database tab changes do not replace conversation data. The snapshot is stored as conversation data for history restoration and export. Include source, data timestamp, delays and missing fields; AI does not fetch market data itself.
+
+This method opens the built-in conversation and returns no model response or AI configuration to the plugin. The initial implementation uses text-only Ask through DBX's HTTP providers and Ollama, without database tools or CLI Agents. If no model is configured, the prompt remains an editable draft so the user can select a model and continue.

 - **Secret persistence:** plugin secrets are removed from connection JSON and stored through DBX's secret-store path. Ordinary cloud-sync snapshots always contain redacted placeholders. Secrets enter sync data only inside the encrypted payload when the user has configured a sync passphrase; without one, plugin secrets remain local and are not synchronized.
