The first app is a Chrome/Edge Manifest V3 extension. It reuses the user's existing authenticated web sessions and embeds the selected model sites as live provider iframes in a single workspace. Providers that are not iframe-safe, currently Grok, run in a controlled top-level tab through the same adapter contract.

Current app

apps/browser-extension

Workspace v2.1 supports:

ChatGPT
DeepSeek
智谱清言
Qwen
Kimi
Claude (best-effort response adapter)
Gemini (best-effort response adapter)
Grok (best-effort response adapter)
Local Prompt Library
Comparison and Agent Handoff

The default comparison set is ChatGPT, DeepSeek, 智谱清言, Qwen and Kimi.

Workspace architecture

AI Parallel Workspace
        │
        ├─ ChatGPT iframe ─ Content Script ─┐
        ├─ DeepSeek iframe ─ Content Script ├─ postMessage bridge
        ├─ Qwen iframe ───── Content Script ├─ native provider rendering
        ├─ Kimi iframe ───── Content Script ┘
        └─ Grok tab ─ Service Worker ─ tabs.sendMessage bridge

Prompts are not transported in destination URLs. The workspace sends one-time jobs to iframe providers through an origin-checked postMessage bridge and to tab-mode providers through a provider-scoped service-worker bridge.

Shared packages will be extracted only when a second client or genuine cross-app duplication requires them.

Development

npm run check

Load apps/browser-extension as an unpacked extension from chrome://extensions/ or edge://extensions/.

Clicking the extension icon opens or focuses the full-page Workspace.

Security and reliability

Uses only the host permissions required by supported providers.
Reuses existing browser login sessions; it does not store provider credentials.
Does not put prompt text into provider URLs.
Renders collected model output as safe text/structured blocks rather than injecting remote HTML.
Provider DOM adapters are best-effort because AI web UIs are not stable public APIs.

See docs/architecture.md for the runtime design and evolution plan.
