The superwhisper alternative — for bilingual speech and AI coding, not for model tinkering

superwhisper is a strong product and its free tier is genuinely generous: unlimited local Whisper models, meeting recording, 100+ languages, at no cost. This page will not pretend otherwise. Here is the narrower case where Ducduc is the better pick — and the wider case where it is not.

The short answer

Pick Ducduc — Pick Ducduc if your sentences switch between Chinese and English, if you dictate instructions into Claude Code or Cursor, or if you want the app to learn the words you keep correcting.
Pick superwhisper — Pick superwhisper if you want to choose and run the recognition model yourself, want the strongest free offline tier, need Windows or mobile, or simply want the lower monthly price.

Where Ducduc wins

Mixed Chinese–English is the design centre. Code-switching mid-sentence is where general-purpose models tend to either translate or transliterate; Ducduc’s cleanup is tuned to leave English terms in English inside Chinese sentences.
Correction learning: fix a misheard word once and it lands in your personal dictionary, and Ducduc offers to replace the remaining occurrences in that field.
A prompt mode aimed at coding agents — a dedicated key turns a ramble into goal, numbered steps and constraints, ready for Claude Code or Cursor.
The one-time licence is $149 against $249.99.

Where superwhisper wins

Pro is cheaper: $8.49 a month against $12.
The free tier is more generous than Ducduc’s in the way that matters most to privacy-first users — unlimited use of local Whisper models, which means free, offline, unmetered transcription.
You choose the recognition model. Ducduc uses Apple’s speech engine and does not let you swap it.
Mac, Windows, iOS and Android. Ducduc is Mac only.
Meeting recording and transcription ship today, and are included in the free tier.

The bottom line

If what you want is control over the recognition model, or free offline transcription with no word budget, superwhisper is the better tool and costs less. Ducduc earns its price in a narrower place: sentences that switch languages, words it learns from your corrections, and speech aimed at an AI coding agent.

Frequently asked

Is Ducduc cheaper than superwhisper?

Not monthly — superwhisper Pro is $8.49 against Ducduc’s $12. Ducduc is cheaper as a one-time purchase: $149 against $249.99. superwhisper also has a stronger free tier, with unlimited local Whisper models.

Why would I pay more for Ducduc?

For three things superwhisper does not do: cleanup tuned for mixed Chinese–English speech, a dictionary that learns from the words you correct, and a prompt mode that turns spoken rambling into a structured instruction for Claude Code or Cursor.

Can I run Ducduc fully offline like local Whisper?

Partly. Recognition runs through Apple’s speech engine on your Mac, and cleanup can run on a local Ollama model, which keeps text on the machine. But Ducduc does not let you pick and run your own Whisper build the way superwhisper does.

Does Ducduc record meetings?

No. Meeting capture is not shipped. superwhisper includes meeting recording and transcription, even on its free tier.
