Verify your download

Compare your file's SHA-256 with this published value. A matching hash checks integrity against this reference; it is not a code signature.

What was checked

For 0.5.0, 42 core tests, 30 native WinUI/WebView2 integration checks, and five packaging-auditor tests passed. Installer checks covered per-user installation, payload hashes, shortcuts and registration, installed-app behavior, repair, and uninstall.

Native tests used synthetic local fixtures and disposable profiles, not personal files or provider submissions. These checks do not establish compatibility with every provider or subscription feature.

What to expect from a preview

The app and Setup are unsigned. Windows may show an unknown-publisher prompt. Provider sign-in, subscription-specific behavior, and independent interactive keyboard use need broader validation. Installing the prerequisite on a clean VM without WebView2 has not yet been validated.

Media captures new supported activity, not old chat libraries or every webpage drop/paste. Downloads do not resume after restart. Claude is its website, not a local Claude Code terminal. There is no automatic updater, tray integration, cross-service chat-content search, or native ARM64/macOS/Linux build.

Keep your provider accounts and browser up to date. If an embedded flow is blocked, use the app's Open in default browser action. Read troubleshooting guidance.
