Nothing to install · 7-day free trial
Get started with Tindra
Tindra runs in your browser — there's nothing to download. Open it, start your free trial right inside the app, and you're writing. No installer, no key to paste.
Works in Chrome, Edge, Safari, or Firefox — on Windows, macOS, Linux, ChromeOS, iPad, or Android.
From here to writing in three steps
-
Open it
Go to app.tindra.ink and create your account. If you like, install it to your device — in Chrome or Edge use the install icon in the address bar, on iPad or iPhone use Share then "Add to Home Screen" — so it opens in its own window like a native app. There's nothing to install on your computer.
-
Subscribe
Start your 7-day free trial right inside Tindra — monthly or yearly. You subscribe in a couple of clicks through Stripe and aren't charged until the trial ends; manage or cancel anytime from the billing portal in the app.
-
Add your key & write
That's it — subscribing unlocks your account instantly, with no key to paste and nothing to activate. Add your OpenRouter key in Settings and start your first novel.
How your subscription works
One subscription unlocks Tindra on your account. Sign in on any device — laptop, desktop, tablet — and your work is there, end-to-end encrypted in transit and at rest, on every machine. Your subscription covers a generous number of devices on the same account.
Cancel whenever you like from the billing portal inside Tindra. Your novels stay yours and exportable either way — to a KDP-ready .docx, Markdown, or a full encrypted backup — and anything we sync is encrypted with a key only you hold.
