Superwhisper vs Speechcap: modes or simplicity.
Superwhisper and Speechcap compete head-on as Mac-first Whisper dictation tools. They make different bets. Superwhisper is configurable to the bone — every dictation can use a different model, prompt, and post-processing chain. Speechcap is the opposite: one paradigm, one hotkey, one pipeline that just works. Both can be right.
Side-by-side
| Superwhisper | Speechcap | |
|---|---|---|
| Platforms | Mac, Windows, iOS | Mac (Windows in beta) |
| Pricing | $8.49/mo or $249 lifetime | $3–6/mo · localised in 89 markets |
| On-device transcription | Yes (smaller Whisper models on free) | Yes (full Whisper on Pro) |
| Custom modes per app | Yes — full power-user setup | No — one paradigm everywhere |
| AI cleanup | Per-mode prompt + LLM chain | Single context-aware cleanup pass |
| Hotkey model | Per-mode bindings | Single push-to-talk key |
| In-flight transforms | No | Hold PTT + I/F/N/G mid-dictation |
| Custom vocabulary | Yes, per mode | Yes, single shared list, cloud-synced |
| Translation | Yes, via mode prompts | Independent always-on toggle |
| Free tier | Limited (small models, 3 modes) | 2,000 words / week, full quality |
| Learning curve | Moderate — modes need configuring | Minimal — one hotkey, one menu |
Where Superwhisper is honestly better
Modes
The headline feature, and it earns its name. A mode is a saved bundle of model + prompt + post-processing rules + activation conditions. "Code comments mode" can use a different LLM prompt than "Slack mode" and auto-activate when you focus on Cursor. If you context-switch a lot, this is a real productivity win.
Lifetime option
$249 once and you're done — appeals to anyone tired of subscriptions. Speechcap is monthly-only today; if avoiding recurring charges is a priority, this is a real Superwhisper win.
Multi-platform
Mac, Windows, and iOS on one license. Speechcap is Mac-only with Windows in beta.
Per-mode customisation depth
If you want to write a custom prompt for how the AI should reshape your dictation when you're writing Python comments vs. Slack messages, Superwhisper supports that. Speechcap applies one cleanup philosophy: "minimal edit, preserve voice." Less configurable; more predictable.
“Modes are a feature you appreciate after the second week and curse during the first. They're not free.”
Where Speechcap is honestly better
In-flight transforms
Hold PTT, speak, press I or F or G before releasing, and the transcript gets improved/formalised/grammar-fixed before it hits the page. Superwhisper requires opening a menu after the fact. Ours is a single keypress.
Price-per-month is lower
$3–6/month with PPP-adjusted localisation in 89 markets. Superwhisper is $8.49/month or $249 lifetime — meaning the lifetime deal only pays back if you'd otherwise stay subscribed for 2.5 years at Speechcap's high tier (or 7 years at the discounted tier). Reasonable people pick differently here.
Onboarding under 90 seconds
Install, grant permissions, pick a hotkey, dictate "hello world." Done. Superwhisper's mode setup is part of the value but also part of the friction.
Who should pick which
- You context-switch heavily and want per-app behaviour.
- You want a one-time lifetime purchase (and Superwhisper's deal is live).
- You need Mac + Windows + iOS on one license.
- You want full control over the AI prompt per mode.
- You want one hotkey and one pipeline, not a mode matrix.
- You'd rather pay $3–6/mo than $249 upfront.
- You want in-flight transforms mid-dictation.
- You prefer push-to-talk and structurally-safe defaults.

Frequently asked questions
Is Speechcap cheaper than Superwhisper?
On monthly billing, yes — Speechcap Pro is $3–6/month with PPP-localised pricing, vs Superwhisper at $8.49/month. Superwhisper also offers a $249 lifetime deal; that breaks even only if you'd otherwise stay subscribed at Speechcap's high tier for ~3.5 years (or 7+ years at the localised tier). Depends on your time horizon.
Does Superwhisper run AI cleanup on-device?
Superwhisper's transcription runs locally (Whisper), but the AI cleanup pass through each mode's prompt typically routes to a cloud LLM (e.g. OpenAI). Speechcap Pro is end-to-end on-device — transcription AND cleanup both run on your Mac. If full offline is the requirement, Speechcap is the only Mac dictation app that delivers it.
Do I really need modes?
Some users do. If you context-switch frequently and want different prompts/models per app (one for Slack, one for code comments, one for legal drafting), Superwhisper's modes are a real productivity gain. If you'd rather not configure a system before using it, Speechcap's single-pipeline-with-app-context approach is the lower-friction choice.
Which has better Mac dictation accuracy?
Both run Whisper models, so on-device accuracy is comparable at equivalent model sizes. Real-world output differs more from the cleanup pass than the transcription itself — Superwhisper's per-mode prompts can produce sharper output for specific contexts; Speechcap's single context-aware cleanup is more consistent across contexts.
Can I migrate my Superwhisper custom vocabulary to Speechcap?
Yes. Speechcap's vocabulary is a flat list of terms, cloud-synced across your devices. Copy-paste from Superwhisper's vocabulary export into Speechcap's Settings → Vocabulary. Modes don't translate (we don't have them), but the vocabulary words do.
