How to Talk to Replit Agent by Voice on a Mac
Replit Agent builds apps from plain-English prompts, which makes it a perfect fit for voice. Instead of typing long specs, you can describe the feature you want out loud and let dictation drop the text straight into the Agent box. Here is how to set that up cleanly on a Mac.
Key takeaways
- Replit Agent runs in the browser and reads plain text, so any system-wide Mac dictation tool can drive it.
- On-device dictation keeps your voice and code prompts on your Mac instead of a third-party server.
- AI cleanup turns a spoken ramble into a tidy, specific instruction before it reaches the Agent.
- The same setup works for Replit, ChatGPT, Claude Code and Cursor, since they all take text prompts.
Why voice fits agentic coding so well
Agentic tools like Replit Agent flipped the workflow: you no longer write the code, you describe the outcome. That shift rewards people who can explain intent clearly and quickly, and speaking is simply faster than typing for most of us. Most people speak around three to four times faster than they type, so a spoken paragraph of requirements lands in seconds instead of minutes.
Voice also lowers the friction of adding detail. When typing feels slow, you write terse prompts and the Agent guesses at the rest. When talking is effortless, you naturally add the edge cases, the styling notes, and the "and also make sure" clauses that produce a better first build. If you want the broader picture, our guide on how to code by voice on a Mac covers the wider workflow beyond Replit.
What you need before you start
You do not need anything on the Replit side beyond a normal account and the Agent view. The dictation happens entirely on your Mac, and Replit only ever sees the finished text. Here is the short list:
- A Mac with Apple Silicon, which BlaBlaType is optimized for.
- A dictation app that types system-wide, meaning into any text field, including a browser box.
- Microphone permission and, on macOS, accessibility permission so the app can insert text where your cursor sits.
- A Replit project open on the Agent screen, ready for a prompt.
Set it up in four steps
Install on-device dictation
Download BlaBlaType from /download/mac and grant microphone plus accessibility permissions. Speech recognition runs locally with Whisper and Parakeet models, so nothing you say is uploaded.
Open Replit Agent and click the prompt box
In your browser, open the Replit project and place the cursor inside the Agent input field. Dictation types wherever the cursor is, so this is the only targeting you need.
Press your shortcut and describe the build
Hold or tap your dictation key and speak naturally: what the feature is, how it should look, and any constraints. On-device AI cleanup strips the "um" and "you know" and fixes punctuation as it goes.
Review, then send to the Agent
The cleaned prompt appears in the box. Skim it for accuracy, tweak a word if needed, and hit send. Add technical terms to the custom dictionary so names like "Postgres" or your variable names transcribe correctly next time.
Why on-device matters for your prompts
When you dictate a feature request, you are often describing proprietary logic, client data models, or an unreleased product. That prompt is as sensitive as the code itself. With an on-device tool, your audio and the transcript never leave the Mac: only the text you choose to send lands in the Agent. That is a very different privacy posture from a cloud dictation service that streams your microphone to its own servers.
This on-device approach is not unique to Replit. The exact same dictation setup drives other AI coding assistants that read text prompts, like Anthropic's Claude Code in the terminal or Cursor in the editor. Learn it once and you can talk to all of them. If your main use is chat rather than code, the same tool covers talking to ChatGPT with voice on a Mac.
Prompt Replit Agent with your voice
Dictate into any app or browser box, get AI-cleaned prompts, and keep every word on your Mac. No card needed for the trial.

Dictation is only as good as the habits around it. A few adjustments make Replit Agent respond more accurately:
- Speak in structure. Say "First, add a login page. Second, connect it to the database." The AI cleanup preserves the ordering and the Agent follows it.
- Name your stack once. Add framework and library names to the custom dictionary so they are never mangled.
- Use custom AI prompts. Set a rewrite style that keeps technical wording intact rather than over-polishing it into prose.
- Dictate in your own language. BlaBlaType supports 90+ languages with optional translate-as-you-speak, which is handy if English is not your first language. For that audience, see our dictation apps for non-native speakers guide.
None of this requires giving up privacy. Because everything runs locally, you can iterate on a build all day without a single audio clip leaving your machine. Check the pricing page for plan details once your trial is done.
Frequently asked questions
Can you use voice to prompt Replit Agent?
Yes. Replit Agent takes plain text prompts, so any Mac dictation tool that types where your cursor is will work. Put your cursor in the Agent prompt box, dictate your request, and the transcribed text becomes the prompt.
Does dictating to Replit Agent send my voice to the cloud?
That depends on the dictation app, not on Replit. If you use an on-device tool like BlaBlaType, your audio is transcribed locally on your Mac and never uploaded. Only the finished text is placed into the Replit prompt box.
How do I get clean prompts instead of rambling speech?
Use a dictation app with on-device AI cleanup. It removes filler words, fixes punctuation and grammar, and turns a spoken ramble into a tidy instruction before the text ever reaches Replit Agent.
