Weesper Neon Flow Review: Offline Dictation for Mac and Windows

Weesper Neon Flow installs like any desktop app, so no terminal is needed. Download the installer for your system from the official site; the speech models are fetched inside the app.

Weesper Neon Flow is a push-to-talk dictation app, not a transcription editor. You hold a keyboard shortcut, speak, and release; the app runs Whisper on the computer and inserts cleaned-up text at the cursor, for example in Gmail, Slack, Notion or Word.

The maker is THE BLUE HOUSE (SASU), based in Paris, and the About page says the product was founded in 2024. It also sells a separate product, Weesper Transcribe, for audio and video files; this review covers only the dictation app.

This review draws on the website, changelog, privacy policy, terms and the GitHub release page. It involved no hands-on testing, so accuracy, speed and stability are not rated here.

Setup is an install, a model download and a shortcut. The steps follow the website and its changelog.

The feature set centres on fast, private dictation into any app. Everything below comes from the website and changelog.

The app runs Whisper through whisper.cpp, with four speech profiles. The FAQ and changelog name Minimal (about 75 MB), Small (512 MB, the default), Medium (1.5 GB) and Large (3.2 GB), plus a Precision profile that was formerly called Turbo.

The download page lists a minimum of 4 GB RAM and 8 GB or more as recommended. On the Mac, an Apple Silicon M1 or newer with Metal is recommended; on Windows, a modern multi-core CPU or a supported Vulkan GPU. Both platforms need a processor with AVX2. The FAQ cites about 600 MB of disk space with the Small model. No speed or accuracy figures were reproduced here.

The privacy policy says speech recognition runs locally and that audio, transcripts, dictated text and clipboard contents are not sent to Weesper servers for transcription. The policy was last updated on 23 July 2026. The terms add that the application operates 100% locally.

The internet is still involved elsewhere: downloads of the app and speech models, license activation and checks through a licensing service hosted on Cloudflare, billing through Stripe, update metadata from GitHub, and optional product analytics (PostHog) and crash diagnostics (Sentry). The policy says analytics events do not include audio, transcripts or dictated text. The code is closed and PromptQuorum did not examine network traffic, so these statements are the maker's own.

It is a paid, proprietary product: a 15-day free trial, then 5 EUR a month, 45 EUR a year or 99 EUR once, with a 7-day money-back guarantee. A personal license covers up to three of your own computers. The site does not say clearly whether prices include VAT, so check at checkout. The free plan after the trial is described two ways: 1,500 words a week in the FAQ and short clips of up to 60 seconds in the changelog.

These are the closest dictation tools in the directory: a free open-source app for three desktop systems, a Mac transcription app with dictation, a free Mac-only dictation app and a hybrid open-source app.

Weesper Neon Flow is a good fit if you want push-to-talk dictation on a Mac or Windows PC where, per the maker, Whisper runs on your own computer, and you accept paying for closed-source software. It has a free 15-day trial, a lifetime option and a recent release.

The caveats are scope and verifiability: no Linux or mobile version, closed code, privacy claims that PromptQuorum could not check, and maker pages that disagree on the free plan and on needing internet. Use the trial before you buy.
