Tutti

Tutti is a Chrome extension that lets you publish to multiple social networks in a single click. Type once in Tutti's popup, pick which networks to send to, and Tutti handles the rest using your existing browser sessions.

What Tutti does

• Multi-network broadcast — one popup, send to multiple networks at the same time.
• Auto-thread split — text exceeding a network's character limit is automatically split into a continuation thread with "(1/N)" prefixes.
• Image attachment with auto-resize — up to 4 images per post, scaled via Canvas to fit each network's per-image size cap.
• Video pass-through — duration and file size are validated against each network's limits before posting.
• Live per-network progress — each row shows in-flight, completed, or failed status as it happens, with the cause inlined on failure.
• Preview mode (default) — Tutti opens each compose page for review and stops just before clicking Post; flip Auto-post on when you're ready to publish for real.
• Persistent draft — closing and reopening the popup keeps your text, attached media, and selections.
• Built-in diagnostics — one-click dump for filing issues when a network changes its UI.

Why Tutti

• Local — works entirely from your browser, reusing existing logged-in sessions.
• Privacy-first — your post content never touches a third-party server.
• User-triggered — Tutti only posts when you click; no scheduled or automated posts.
• Free — no subscription, no paid API.

How it works
Tutti drives each network's web compose page using your existing browser session. Posts go through the same path as if you had typed and clicked manually, just automated.

See the screenshots above for the list of networks Tutti currently supports. The project page on GitHub has the full feature documentation.
