What is the best Wispr Flow alternative that works offline?

SparkFlow runs Whisper and Parakeet speech models entirely on your machine, so dictation keeps working with the internet disconnected. Wispr Flow processes audio in the cloud, which requires an internet connection.

Is there a cheaper alternative to Wispr Flow?

SparkFlow costs $5 per month with no word caps after a 7-day fully featured free trial. Wispr Flow Pro is $15 per month (or $144 per year), and its free tier is limited to 2,000 words per week.

Does SparkFlow have word limits?

No. SparkFlow has no weekly or monthly word caps. Because the speech models run on your machine instead of a cloud server, there is no per-word cost to pass on — dictate all day, the price stays $5.

Wispr Flow Alternative

Same idea.
Your words, your machine.

Wispr Flow sends your voice to the cloud and charges $15/month for it. SparkFlow runs the speech models on your own PC — hold a hotkey, speak, and clean text appears at your cursor. $5/month flat, no word caps, and it keeps working with the Wi-Fi off.

Common questions

Does SparkFlow work without internet?
Yes. The models run locally and transcription happens on your machine. Disconnect from the internet and dictation still works — that's the simplest way to verify it yourself.

What does the free trial include?
Everything, for 7 days. No card, no account. After that it's $5/month — cancel any time and keep using it until the month you paid for is up.

What do I need to run it?
Windows 10 or 11, x64. A GPU is optional and makes transcription faster; without one, the CPU model does the work. macOS and Linux builds land with the next release.
