Guides

OSSFlow is free, open-source voice dictation for Android. These guides answer one question each: how to dictate into an app, how to add a key, and how OSSFlow compares with other tools as of October 2026. The install itself stays on the setup guide.

How to use this list

Start with the setup guide if the bubble is not on screen yet. Sideloaded apps also need restricted settings before Display over other apps and Accessibility will turn on.

Comparisons are dated October 2026 and link to the other product's own pages. They do not score accuracy, and they do not invent prices. If a product is the better tool for a job, the page says so.

Start

  • Install OSSFlow and add an API key

    Download the APK, allow restricted settings, add a Grok or OpenAI-compatible key, and dictate once.

  • Allow restricted settings

    Sideloaded apps need this before Display over other apps and Accessibility will turn on.

  • Privacy

    What is sent to the transcription and cleanup providers, and what stays on the phone.

  • FAQ

    Offline use, providers, cost, and what Android 17 Advanced Protection changes.

  • Wispr Flow on Android, compared with OSSFlow

    As of October 2026, Wispr Flow on Android is a floating bubble that uses Wispr's own service and an account. OSSFlow is free, open-source voice dictation for Android: you bring an API key, and there is no account. This page does not claim that either app is more accurate.

Roundups

How-to guides

    How to dictate a WhatsApp message on Android with OSSFlow: focus the chat field, tap the bubble, and paste cleaned text. You still press send yourself.

  • Grok speech-to-text on Android

  • Set a Groq or OpenAI API key

    Set a Groq or OpenAI API key in OSSFlow for Android dictation. Use the OpenAI-compatible base URL and model. No prices, no OSSFlow account.

  • Voice typing when typing hurts

    Voice typing on Android can mean less tapping when your hands hurt. OSSFlow pastes into the focused field. This is not medical advice or a medical device.

  • Voice typing and dyslexia

    Dictation on Android can help you get words down when spelling is the hard part. OSSFlow is not a dyslexia treatment, and you still read the result.

  • Dictate AI prompts on Android

    Dictate a prompt into ChatGPT, Claude, Gemini, or any Android field with OSSFlow. Cleanup returns the words you meant. It does not run the prompt.

Use cases

  • Voice dictation for students

    Students can dictate notes and essay drafts on Android with OSSFlow. It pastes into the open field. It does not record a lecture or join a class account.

  • Voice dictation for writers

    Writers can dictate drafts on Android with OSSFlow: writing styles, a personal dictionary, and custom cleanup. It pastes into the editor you already use.

  • Voice dictation for developers

    Developers can dictate issues, docs, commit messages, and chat on Android with OSSFlow. It pastes text. It is not a code-aware IDE.

  • Multilingual voice dictation

    OSSFlow's default Grok language is English, and it does not translate. Another OpenAI-compatible model can transcribe languages that model supports.

Questions

Which page should I open first?
The setup guide, if OSSFlow is not installed. After that, open the guide for the app you want to dictate into, such as WhatsApp or Gmail, or the comparison for the tool you use now.
Does OSSFlow work offline?
No. Transcription needs a network connection to the provider you set. OSSFlow does not run a speech model on the phone.
What does OSSFlow cost?
The app is free, bring your own key. There is no account and no OSSFlow subscription. You pay the API provider you choose.
Where is the full install?
On the setup guide: the APK, restricted settings, the API key, and the first dictation. These guides assume that install is done.
