Spill It! — Voice to text that sounds like you

6 min read Original article ↗

You think faster
than you type.
So stop typing.

Talk the way you think. What lands in your email, your Slack, your code — sounds like you on your best day. Still your voice. Just a little tidier. On your Mac. Your data stays yours.

You just talk. The rest sorts itself out.

Your words, your phrasing — just without the parts you didn't mean.

The ums you didn't mean

They're gone. But when you say "really really" — that stays. You meant it.

I uh I think we shouldI think we should

You say the number, it writes the number

"March thirty first at three thirty" — you said it naturally. It shows up the way you'd type it.

march thirty first at three thirtyMarch 31st at 3:30

It knows who you're talking about

Your contacts, your files, your branches — already on your screen. So the names come out right.

Say it like a sentence, get it like code

"services slash auth slash middleware dot go" — you said it the only way that makes sense. It figures out the rest.

services slash auth slash login dot goservices/auth/login.go

Changed your mind? It caught that

You corrected yourself mid-sentence. Only the version you meant makes it through.

let's do 3 PM scratch that 4 PMlet's do 4 PM

Whisper. It still works.

Open office, sleeping partner, library — just lower your voice. You're the only one who knows.

What this costs. Honestly.

What "bring your own API key" means.

AI polish works with your choice of AI provider. Here's how that works and why.

1

You pick a provider

We recommend Cerebras or Groq — both run fast, open-source models. You can also use OpenAI, OpenRouter, or any compatible provider. Sign up on their site and grab an API key. Takes about 2 minutes.

2

You paste the key into Spill It!

Go to Settings → Cloud AI, pick your provider, paste the key. Pick a model — we show you speed, cost, and quality tags to help you choose. Your key is stored locally on your Mac, fully encrypted. We can't read it, and neither can anyone else.

3

AI polishes your text on every dictation

After transcription, your text is sent from your Mac directly to the provider for refinement. They add structure, punctuation, smarter cleanup. The result lands at your cursor. You can turn it off anytime.

The tradeoff triangle: speed, cost, quality

Different models give you different combinations. You choose what matters most.

Fast open-source model
e.g. Qwen3 235B on Cerebras
~2100 t/s Medium High

Small cheap model
e.g. Llama 3.1 8B on Groq
~1800 t/s Low OK for short text

Premium model
e.g. Claude 3.5 Haiku on OpenRouter
~99 t/s Higher Best

What does this cost you? It depends on the model you pick and how much you dictate. The app shows you a personalized cost estimate based on your actual usage — light, medium, or heavy — right in the settings. A lighter model on Cerebras or Groq will cost significantly less than a premium model on OpenAI.

Our recommendation: Start with Cerebras (Qwen3 235B) — it's fast, high quality, and reasonably priced. If cost is your priority, try a smaller model first and see if the quality works for you.

Your words. Your business.

Here's exactly what stays private and what doesn't. No fine print.

Without AI polish

Nothing leaves your Mac.

Your voice is transcribed, cleaned up, and formatted entirely on your machine. No audio, no text, no prompts ever touch our servers or anyone else's.

  • Voice processed on-device — never uploaded
  • Transcription stays local — we never see it
  • Works fully offline — no internet needed
  • Only outbound call: license check with our server
  • Optional: crash reports (Sentry) if you enable them
  • Optional: anonymous analytics (PostHog) if you opt in

With AI polish

Your text goes to the AI provider you choose. Not to us.

When you enable AI polish, your transcribed text is sent directly to the API provider you configure — OpenAI, Anthropic, or others. It goes from your Mac to their servers. We never see it, route it, or store it.

  • You bring your own API key — we don't provide one
  • Text goes directly from your Mac to the provider
  • Our servers never see your prompts or responses
  • What the provider does with your data depends on their policy
  • Most providers let you disable data retention
  • You can turn AI polish off at any time

Our recommendation: If you use AI polish, check your provider's data retention settings. Most (OpenAI, Anthropic) let you opt out of having your data used for training. We encourage you to do that. Your words are yours — even the polished ones.
