**TL;DR:** Apple Dictation is free and built into macOS — solid starting point, but the 30-second auto-stop and lack of custom vocabulary are real friction. Superwhisper at $249.99 lifetime brings Whisper Large on-device, per-app modes, and no session caps. The catch: it saves audio recordings to disk by default with no opt-out, which matters for compliance work.

**Apple Dictation (5.5/10):**
- $0 — built into every macOS install, zero setup beyond enabling in System Settings
- On-device on Apple Silicon (M1+), but has an undocumented cloud fallback Apple doesn't document
- 30-second session auto-stop — long-form dictation requires constant restarts
- No custom vocabulary — technical terms, names, and jargon mistranscribed every time
- No HIPAA Business Associate Agreement from Apple
- Intel Macs route every request to Apple's servers — on-device only applies on Apple Silicon

**Superwhisper (7.5/10):**
- Free tier (small models) · $8.49/mo · $84.99/yr · $249.99 lifetime
- Full Whisper model selection: tiny, base, small, medium, large-v3, distil-large-v3
- Per-app modes — set different dictation styles for email, Slack, code, custom prompts
- Optional cloud LLM post-processing (bring your own OpenAI/Anthropic/Groq API keys)
- Saves audio recordings to disk by default with no option to disable — may sync to iCloud
- Available on macOS, Windows, and iOS

**Verdict:**

The 30-second cap is the real dealbreaker for Apple Dictation, not accuracy. Superwhisper solves that and adds per-app modes and model selection — but the audio-to-disk default is worth knowing before you commit.

For regulated work (legal, medical), Superwhisper's recording behavior complicates compliance even though transcription runs locally. Audio persisting in an iCloud Documents folder is PHI exposure territory.

Right answer depends on whether the 30-second cap actually blocks your workflow.
