What's New in v0.19.21

v0.19.21 brings Ask AI to plan review and annotate mode. The same inline AI chat that was available in code review now works when reviewing plans, annotating markdown files, annotating URLs, and annotating HTML documents.

Ask AI in Plan Review and Annotate Mode

Select any text in a plan or annotated document, open the comment popover, and click "Ask AI" to ask a question about the selected content. The response streams into a side panel that persists alongside the annotation panel. You can switch between annotations and AI chat using the sidebar tabs, and both stay independent of each other. AI chat messages are never included in approval or denial feedback.

The feature uses the same provider-agnostic backend that powers code review AI. Any provider you have installed (Claude, Codex, Pi, OpenCode) works automatically. If you have multiple providers, the system picks a default based on which agent runtime you're using (Claude Code defaults to Claude, Codex defaults to Codex, and so on) and you can override it from the AI settings bar at the top of the chat panel.

A one-time announcement dialog appears the first time Ask AI is available in plan review, then dismisses permanently via cookie. Users with no AI providers installed see no change at all.

Shared AI Runtime

The AI provider setup that previously lived inline in the code review server has been extracted into a shared ai-runtime module. All three servers (plan review, code review, annotate) and the Pi extension now use the same initialization path. This means provider detection, session management, and SSE streaming are consistent across every Plannotator mode.

The refactor also fixed a missing SSE timeout in the code review server. Long-running AI responses could previously be cut off by Bun's idle connection timeout. All three servers now correctly disable the timeout for /api/ai/query requests.

Origin-Aware Provider Defaults

When multiple AI providers are available, Plannotator now picks a default based on which coding agent launched the session. Claude Code sessions default to Claude, Codex sessions default to Codex, Pi sessions default to Pi, and OpenCode sessions default to OpenCode. You can still override the selection manually, and your per-origin preference is saved separately so switching between agents doesn't reset your choice.
