Frequently asked questions
Is there a free trial?
Yes. After you register, your first 7 days include full Pro access at no cost -- unlimited voice input, all 30+ languages, translation mode, and AI polishing. No credit card required to start.
What happens after the free trial?
After your 7-day free trial, you can continue using Flow with a limited free quota. Choose Plus ($3/month) for 12,000 words/week, or Pro ($12/month) for unlimited voice input. Both plans offer annual billing with savings.
Can I cancel anytime?
Yes. Both plans can be cancelled at any time. Your subscription remains active until the end of the current billing period. No cancellation fees.
Is the app free to download?
Yes. Flow Keyboard is free to download on both macOS and iOS. You can start using it immediately with the free trial -- no payment upfront.
Does one subscription work on all devices?
Yes. Your subscription is tied to your account, not a specific device. Use Flow on your Mac and iPhone with the same subscription.
What payment methods do you accept?
Subscriptions are available via in-app purchase on both iOS (App Store) and macOS. One subscription covers both platforms — subscribe on either device and the other unlocks automatically.
Why does Flow charge a subscription fee?
When an input method is free, you're usually paying with your data — through ads, recommendations, or training AI models with your keystrokes. Flow doesn't do any of that. We don't collect, store, or monetize your data. Your voice and text are processed in real time and discarded immediately.
Flow is powered by large language models that run in the cloud. Every time you speak, there's real computing cost to turn your voice into clean, polished text. This is an AI service, not a traditional input method.
That said, Flow also offers a free weekly quota that covers basic daily use — you can try it without paying anything.
What you're paying for with a subscription is the ability to express more, output more — speaking is 4x faster than typing, and your ideas come through complete and unfiltered.
