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, 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) | 2,500 words/wk (cloud); Pro = unlimited on-device |
| 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, audio never leaves the device. If full offline is the requirement, Speechcap Pro 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.
