Need help? We're here.

Visit psitta.ai/download on a Windows 10 or 11 PC. Click the Install button to download psitta.appinstaller, then open the downloaded file. Windows App Installer launches automatically — click Install. Psitta appears in your Start menu within 60 seconds. No admin rights required.

Psitta is currently a Windows desktop application — that's where writers do their deepest work. We're focused on shipping the best possible Windows experience first. macOS and mobile companion apps are on our roadmap, but we're not announcing dates yet. Want to be notified when they launch? Email support@psitta.ai and we'll add you to the announcement list.

Currently: PDF, DOCX, and plain text. We're working on EPUB, HTML, and Markdown for future releases.

No. Psitta requires an internet connection to synthesize voice and check for updates. Your documents stay private to your account, but voice generation happens server-side.

Writing Nook is the complete Psitta platform: the full Writing Desk, unlimited projects, Blueprints with 25+ narrative structures, scene mapping and progress tracking, Story-Coach, the Structure Analyzer, AI assistance, and writing analytics — plus Reading & Revision with premium natural voices, word-level highlighting, and playback up to 4×.

Each billing period includes 250,000 premium voice characters and a generous AI allowance. If you use up the premium voice allowance, Psitta switches to standard voices for the rest of the period — playback never interrupts — and everything resets at your next billing cycle.

Your 14-day trial includes everything in Writing Nook. When it ends, your subscription starts on the plan you chose at checkout — nothing changes in the app, you just keep writing.

If you cancel before the trial ends (Settings → Manage Subscription), you won't be charged. You can keep writing on the free experience: your documents and projects stay exactly where they are, listening continues with standard voices, and the premium capabilities simply lock until you subscribe again.

Everything starts inside the app. Create your free account, and when you're ready, start your 14-day Writing Nook free trial from the Plans screen — checkout is handled securely by Stripe. You can switch between monthly and annual, or cancel, at any time from Settings → Manage Subscription.

Creative Nook is coming soon. It builds on everything in Writing Nook and adds a full Creative Studio — inside the same Psitta application, no separate app. It isn't purchasable yet; you can join the waitlist on the pricing page and we'll email you when it launches.

Open Psitta → Settings → click Manage Subscription — this opens the Stripe billing portal where you can change plans, update payment method, or cancel. Cancellations remain active through your current billing period.

Yes. Psitta is signed with our development certificate, but Windows SmartScreen flags any app it hasn't seen many times before. This is normal for new applications. Click 'More info' → 'Run anyway' to proceed. We'll move to a fully verified Microsoft Store distribution later this year.

Most issues fall into a few categories — try these in order:

Document won't open or upload: Confirm the file is .pdf, .docx, or .txt and under 100 MB. If the file is corrupted or password-protected, Psitta won't be able to read it.

Voice won't play: Check your internet connection — Psitta requires a connection for voice synthesis. If the issue continues, try Settings → restart the app.

App won't launch: Try restarting your computer. If the issue persists, uninstall and reinstall via psitta.ai/download — your account, documents, and progress are saved on our servers and will restore on next sign-in.
