JEXXA - On-device dictation that never leaves your Mac
Show HN: Jexxa: High Speed on Device Dictation
JEXXA is a high-speed, on-device dictation app for macOS 14+ on Apple silicon. Hold a key, speak, and words appear where your cursor is—in any app. Everything runs locally: no audio or transcript is uploaded, and it works offline. Most dictations are typed within a fifth of a second, with no queue or per-minute cost. It learns your names and jargon, lets you undo with voice commands like 'JX minus one', and shows a live preview. Choose JEXXA (3.1 GB) for 16GB+ Macs or JEXXA Small (2.0 GB) for 8GB. $8/month unlimited.
The model is on your disk. Hold a key, speak, and the words appear where your cursor already is — in any app that takes text.

I spent ~10 minutes looking at it.
Vibe-coded website.
Both bundles contain quantized versions of the CohereLabs/cohere-transcribe-03-2026 model. The model in JEXXA.dmg is MLX int8 g64 affine quantized. JEXXA-Small.dmg has the same model but MLX int4 g32 affine quantized. There's also an int8 quantized WeSpeaker ECAPA-TDNN speaker-verification ONNX encoder. No acknowledgments for both models (doesn't the Apache 2.0 license require it? WeSpeaker's cc-by-4.0 license certainly does). Both bundles also contain full-blown Python 3.12.8 runtimes with about a dozen packages installed.
Apps are unsandboxed menubar apps and also contain PostHog analytics and Supabase auth. So, I wouldn't run it on any of my machines.
A few engineering hygiene issues like a .pytest_cache directory, Python code, .DS_Store files, etc.
Given the above, I suspect the "I am training better models." is just marketing speak.

One price, indefinitely for the rest of your life. The developer isn't maintaining any infrastructure, there's no ongoing cost whatsoever, so there's no reason for monthly payments.
It's just a static file on your own computer that's burning your own CPU cycles. Sorry, but it just feels a bit greedy to me.
