Flow vs SuperWhisper
Two takes on the same problem. SuperWhisper runs Whisper locally (privacy-first, offline-capable). Flow uses Groq's LPU for cloud Whisper at sub-second latency. Different tradeoffs.

SuperWhisper runs Whisper models on your own machine. Audio never leaves your laptop. That's a real advantage if you're dictating sensitive material, working offline, or in a regulated environment.
Flow runs in the cloud — your audio is sent to Groq, transcribed by Whisper Large v3 Turbo on their LPU, returned within ~300-800ms, then discarded. The advantage is speed (5-10× faster than even an M2 Mac running a local model) and quality (Groq runs the largest Whisper model, which is hard to fit locally on most consumer hardware).
SuperWhisper is cheaper at $8.49/mo standard ($84/yr). Flow is $16.99/mo. The price difference reflects that Flow is paying for Groq compute (which is what enables sub-second latency); SuperWhisper uses your machine's compute. Both are reasonable.
The Team plan flips this — SuperWhisper doesn't have one. If you're a 5-person company that wants centralized billing, shared snippets, and admin controls, Flow's $49.99/mo is your only option in this comparison.
