The short answer depends on where you speak.
Wispr Flow and Relay both turn speech into finished text in the app you are using. Neither is a plain transcriber, and describing Flow as a word-for-word tool would be unfair. The real differences are where each app runs, what it does once you have spoken, and how much you want the app to act rather than type. Relay believes the keyboard has become the bottleneck for working with AI, so it is building a voice interface for the apps you already use rather than another chatbot; why we think so.
If most of your dictation happens on a phone, Flow is the practical choice today. If your day is on a Mac and the job is often more than a sentence at the cursor, Relay is worth a trial. For the wider field, including Apple Dictation, Aqua Voice and Superwhisper, see the Mac dictation app comparison.
Platforms: Flow is broader today.
Wispr Flow’s documentation lists Mac, Windows, iPhone and Android. Its pricing page also lists a Notetaker for Mac and Windows. That reach is Flow’s clearest advantage if you want one dictation habit across devices.
Relay for macOS requires an M-series Mac running macOS 14 or later. Relay for Windows is in public Beta on Windows 11 (64-bit, x64), and Relay Skills are not available on Windows yet; the Windows Beta guide covers the differences. iOS and Android versions are in development and expected later, closer to January 2027. If you need mobile dictation now, that settles it in Flow’s favour.
Writing style and context: both adapt, in different ways.
Flow’s Styles group apps into Personal, Work, Email and Other, with tones that range from Formal to Casual. Its features page says Styles are English-only and desktop-only. Flow’s data controls describe Context Awareness, which may use relevant text from the active app window. A Dictionary and Snippets are on every plan.
Relay shapes wording for the application, the recipient, your language, the tone and your established preferences, and it draws on long-term memory about the people you write to and the terms you use. That memory is stored on your Mac, where you can edit or delete it; excerpts go to AI providers when a request uses them or when the memory is updated, and aren’t stored by Relay. Relay also aims at final intent: if you change your mind halfway through a sentence, the result is designed to keep the version you meant.
Context awareness is not unique to either product. The useful test is whether the text matches what you would have typed, in the app and to the person you are writing to.
Beyond dictation: Command Mode vs Relay Skills.
Flow’s Command Mode is an experimental setting on Mac and Windows. You hold Fn+Ctrl and speak an instruction; Flow sends the contents of the current text box and any selected text with it. It is available on Pro, during trials and on Enterprise. For developers, Flow lists variable recognition for camelCase and snake_case and file tagging in Cursor and Windsurf.
Relay treats typing as one possible outcome. In Terminal it can produce the command you meant rather than prose describing it. It can find web-grounded information, such as a Google Maps link, and insert it where you are writing. And you can build custom Relay Skills with a Skill Builder that uses a coding agent to connect Relay to your own tools. Skills can route content to an intended app and recipient; try each one on your own workflow before relying on it.
Privacy: both are cloud services with stated limits.
Flow’s data controls page says transcription always occurs in the cloud and that Wispr keeps zero data retention agreements with its third-party AI providers, with Notetaker briefs excluded. Its pricing page lists SOC 2 Type 2 on every plan, and HIPAA with a business associate agreement on Growth and Enterprise. Model training is controlled by a setting called “Improve the model for everyone”.
Relay records only after you start capture with its recording key, in hold or toggle mode. Its Privacy Policy says audio, a current-window screenshot when a request needs it, and on-screen context are sent to AI providers through Relay’s servers and not stored by Relay; providers follow their own policies. Neither app is the right choice if nothing may leave your computer; see offline dictation on a Mac.
Pricing checked October 29, 2026.
Wispr Flow’s pricing page lists a Free plan with 2,000 words a week on desktop and limited weekly use on mobile; Pro at US$15 per user monthly, or US$12 per user a month billed annually; Growth at US$23 monthly or US$18 annually; and custom Enterprise pricing. There is no lifetime plan.
Relay Unlimited is US$15 a month after a 14-day trial with no credit card; Relay pricing explained covers the Free tier and the Early supporter bundle. These are list prices; currency, tax and checkout may differ.
Test both with the same three tasks.
Pick a reply to a real colleague, a paragraph where you change your mind midway, and one task beyond typing: a Terminal command, a link to insert, or a Command Mode edit. Run each in both apps, in the app you actually use, and count the corrections you had to make.
Review each Privacy Policy before using either app with sensitive material. Choose the app whose results you would send without rewriting, and remember that Relay Q is optional: Relay works on its own.
