Wispr Flow does not have autocorrect. It is a voice transcription tool: it converts speech to typed text with high accuracy, but it does not monitor or correct what you type manually. For correction you need a separate tool. Charm runs alongside Wispr Flow: it corrects what you type as you type it, and fixes spelling errors, grammar mistakes and transcription artifacts in a dictated block when you select it (or select nothing, to fix the whole field) and press Option-Command-V.
What does Wispr Flow actually do?
Wispr Flow is a voice dictation application for Mac. You activate it with a keyboard shortcut, speak your message, and it transcribes your speech directly into whatever text field is active - email, Slack, Notion, Google Docs, a browser address bar, anywhere.
Its strength is transcription accuracy. It handles accented speech, technical vocabulary, and natural spoken language better than Apple's built-in dictation for many users. It is particularly good at removing filler words ("um", "uh") and formatting speech naturally into written text.
What it does not do: spell-check, grammar-check, or correct text that you type with your keyboard. Its job begins and ends at the audio-to-text boundary. Everything after that - checking accuracy, correcting errors, improving phrasing - is outside its scope.
At $120 per year, it is a premium voice input tool. But roughly 97% transcription accuracy means around 3 errors per 100 words still make it through. At 130 words per minute dictation speed, that is 4 errors per minute entering your text - errors that need to be caught somewhere downstream.
Why does Wispr Flow not include autocorrect?
The two functions are architecturally different. A dictation app operates at the audio layer - it processes microphone input and converts it into text. Autocorrect operates at the text layer - it monitors text as it appears in a text field and modifies it in real-time.
Building both into the same application would require the dictation app to also become a system-level Accessibility API tool, monitoring all text input continuously. That is a fundamentally different kind of software with different permission requirements, different performance characteristics, and different failure modes.
The design decision makes sense: it does one thing extremely well. The correction layer is better handled by a dedicated tool. This is the same reason you use a separate app for email and a separate app for calendar, even though both involve scheduling.
The best autocorrect to use with Wispr Flow on Mac
Charm fits alongside it in two ways. Anything you type yourself, including edits to a transcription, is corrected as you type. A transcription block the dictation app inserts arrives all at once, so Charm does not fix it on its own: select it (or select nothing, to fix the whole field) and press Option-Command-V, and Charm fixes spelling and grammar in that text in one go.
The features that matter most when pairing with Wispr Flow:
- Spells - Catches misspellings in transcription output and corrects them within 200ms. The cyan glow shows you a correction has been applied.
- Polish - Catches grammar errors at punctuation boundaries. Fixes agreement errors, missing words, and awkward phrasing that sometimes appears in transcribed speech.
- Works across your Mac - Dictation works across your Mac, and so does Charm. The combination covers the full surface of your Mac workflow.
Charm costs $19.99 as a one-time purchase. There is no subscription, no account required, and it requires macOS 14 Sonoma or later. The total cost of the Wispr Flow + Charm stack is $129.99 in the first year, with Charm never needing renewal.
Setting up Wispr Flow and Charm together
Both tools install and run in the background without conflict. Here is how to configure them:
- Install Wispr Flow and configure your preferred activation shortcut (typically a double-tap of a modifier key)
- Install Charm from www.theodorehq.com/charm
- Grant Charm Accessibility permission when prompted: System Settings > Privacy and Security > Accessibility
- Enable Spells and Polish in the Charm menu bar settings
- Test by dictating a sentence with Wispr Flow, then press Option-Command-V to have Charm fix any transcription errors in the field
You do not need to configure any interaction between the two apps. Charm corrects what you type as you type it; for a transcription, select it (or select nothing, to fix the whole field) and press Option-Command-V. The two tools are fully independent and complement each other by design.
Frequently asked questions
Does Wispr Flow correct spelling?
No. Wispr Flow transcribes speech to text but does not monitor or correct typed text. Spelling correction requires a separate tool. Charm corrects what you type as you type it, and fixes a dictated block when you select it (or select nothing, to fix the whole field) and press Option-Command-V.
Can Wispr Flow fix grammar mistakes?
Not in real-time. It transcribes speech accurately but does not apply grammar correction to the resulting text. Charm's Polish feature corrects grammar in what you type at punctuation boundaries, and fixes a dictated block when you select it (or select nothing, to fix the whole field) and press Option-Command-V.
What is the best autocorrect to use with Wispr Flow?
Charm is the best autocorrect companion for Wispr Flow on Mac. It corrects what you type as you type it, fixes a transcription in one keystroke (select it, or nothing, and press Option-Command-V), and costs $19.99 once with no additional configuration needed.
Does Charm work while Wispr Flow is active?
Yes. Charm and Wispr Flow operate at different layers and do not conflict. The dictation app handles audio transcription; Charm corrects what you type, and fixes a transcription when you press Option-Command-V. Both run in the background without any additional setup.
How accurate is Wispr Flow at transcription?
Accuracy is high for clear speech, but names, technical terms and homophones still slip through, and at dictation speed a few small errors add up quickly. Selecting the transcription and pressing Option-Command-V has Charm fix them before you send.
