Frequently asked questions

Everything you need to know about Waffler.

Do I need an account?
No. There is no account needed for Waffler. Download the app, add your API key, and you're ready to go.
Is it really free?
Yes — Waffler itself is completely free and open source (MIT licensed). You bring your own API key for the speech-to-text service. Groq offers a generous free tier that works great for everyday use, so you may not need to pay anything at all. If you prefer OpenAI or need higher usage limits, their rates are very affordable — roughly $0.006 per minute of audio.
Is my data private?
Waffler has no servers and no backend — it runs entirely on your machine. Audio is sent directly from your device to whichever API provider you choose (OpenAI or Groq) under your own API key. Waffler never sees or stores your audio. However, your chosen provider will process your audio under their own data policy — you're in control of which provider you use. See how each provider handles your data →
What's the difference between OpenAI and Groq?
Both work well. Groq is generally faster and has a free tier that's great for most users. OpenAI Whisper is more widely used and well-documented. You can add whichever API key you already have during setup — switching between them is easy.
Why does it warn about an unidentified developer / unsafe app?
Waffler builds are unsigned — code signing certificates cost money and this is a free indie project. On Windows, click "More Info" then "Run Anyway" to get past SmartScreen. On Mac, open System Settings > Privacy & Security, scroll down, and click "Open Anyway" next to the Waffler message. This is normal for unsigned open-source software.
How do I get an API key?
It takes about 2 minutes. We recommend Groq — it's fast and has a generous free tier. Just sign up at console.groq.com, create a key, and paste it into Waffler. We have a full step-by-step guide at How to Get an API Key.
Mac or Windows?
Both are supported. Separate installers are available on the GitHub releases page at github.com/jbf-tars/waffler/releases.
Can I request a feature?
Absolutely! We build Waffler based on what users actually want. Head to our GitHub Discussions to suggest ideas, vote on others, or join the conversation.
