use.fo - AI Voice Typing

use.fo is an iPhone keyboard designed for people who write a lot on mobile and want AI help without leaving the app they are already using. It turns speech into polished text and inserts it directly back into the current text field, so the user does not have to switch apps, copy text, paste it back, and clean it up again. The result is a faster and more natural writing workflow on the phone.

The app works in everyday places where people actually type: iMessage, Gmail, WhatsApp, Slack, LinkedIn, Notes, and any other text field where the iOS keyboard appears. Users hold to speak, choose a mode such as Email, Work, Translate, Social, or Proofread, and get output that is ready to send. The goal is not raw transcription. The goal is to make mobile writing feel clear, useful, and immediately actionable.

use.fo is built for mobile-first professionals such as support reps, salespeople, product managers, marketers, creators, and anyone who spends real time writing from an iPhone. It also includes reusable prompt shortcuts and writing patterns that sync through the user's own Google Drive, which helps people keep personal workflows organized without depending on a third-party prompt database. That makes the product useful both for everyday messages and for repeatable templates that save time over the long run.

Privacy and platform constraints matter here. Voice transcription and AI rewriting run through secure cloud infrastructure, while API keys are never stored on the device. On iOS, keyboard extensions have real limits, so the product is designed around a short, explicit, reliable round trip instead of pretending the system can behave like a desktop app. That approach keeps expectations realistic and makes the workflow dependable.

The practical benefit is simple: less context switching, less friction, and less time wasted moving between an AI app and the app where the user actually wants to write. For anyone who spends the day responding to messages, drafting replies, translating text, or rewriting short bursts of content from a phone, use.fo puts AI voice typing at the center of the keyboard rather than as a separate destination.

It also helps users who know the rough idea but want cleaner wording on the first pass. A short spoken thought can become a professional reply, a concise social post, a translated message, or a polished prompt for another AI tool. The experience is intentionally lightweight so the keyboard stays close to the moment of writing and the output feels like part of the same thought, not another app in the middle of the workflow.
