The free, on-device Willow Voice alternative for Mac
Both turn speech into polished text. The difference: EnviousWispr runs entirely on your Mac, costs nothing, and never sends your audio to the cloud.
Feature comparison
An honest look at how the two tools stack up across the dimensions that matter most.

Why Mac users switch from Willow Voice
Willow Voice is cloud-first with a subscription model. EnviousWispr was built around a different premise: your voice data belongs on your device.
No subscription, no word limits, no freemium tiers. Willow Voice caps its free plan at 2,000 words per week. The paid plan costs $12/mo billed annually, or $144 per year. EnviousWispr is free with no limits.
Willow Voice processes audio on cloud servers. EnviousWispr processes every recording on your Mac's Neural Engine. Privacy is the architecture, not an option. See how the pipeline works.
Median time to text is 0.43s on Apple Silicon. With AI polish, 1.5s. No network round-trips, no server queues. Immune to bad Wi-Fi, VPN latency, or cloud outages.
Download, open, start dictating. EnviousWispr never asks for your email, never requires a login, never phones home. No trial period, no conversion nag.
Apple Intelligence and Ollama run entirely on-device. Want cloud speed? Bring your own OpenAI or Gemini key. You control which services touch your text, if any.
Every line is on GitHub under BSL 1.1. Verify what it does. Report issues directly. Contribute improvements. Closed-source dictation tools ask you to trust their privacy claims on faith.
The details that make dictation reliable
Cloud dictation tools outsource the hard problems to servers. EnviousWispr solves them locally, and the result is a more dependable workflow.
Cloud dictation has a timing problem. While your audio uploads, transcribes, and returns, you might switch apps, click a different field, or start reading something else. When the text finally arrives, it can paste into the wrong place or overwrite your clipboard.
EnviousWispr captures which app and which text field had focus when you started recording. After transcription, it re-activates that exact app and inserts text directly via the Accessibility API. If direct insertion fails, it falls back to simulated Cmd+V, then to AppleScript. Your clipboard is saved before the operation and restored after.
When you run speech through an LLM for cleanup, there is a real risk: the AI can hallucinate extra sentences, "answer" your dictation as if it were a question, or inject preamble like "Certainly! Here is the corrected text." These are not theoretical problems. They happen with basic LLM integrations.
EnviousWispr uses three layers of defense. Short transcripts (three words or fewer) bypass the LLM entirely because there is nothing to polish. Medium transcripts get aggressive prompt reinforcement to prevent creative expansion. All output is validated: if the response is more than three times longer than the input, it is rejected as probable hallucination and the raw transcript is used instead.
Where does your voice go?

Fast because there is no upload step
On Apple Silicon Macs, EnviousWispr transcribes speech locally. No network round-trip before text appears.

Choose Willow Voice if you need cross-platform or enterprise compliance
Willow Voice is a well-funded, YC-backed product with broad platform support and enterprise features. It may be a better fit in these situations:
Willow Voice runs on Mac, Windows, iOS, and Android. EnviousWispr is macOS only. If you dictate across multiple operating systems, Willow covers all of them.
Willow Voice offers SOC 2 and HIPAA compliance on its Enterprise tier, with team pricing at $10/mo per seat. EnviousWispr is a single-user desktop app without enterprise certifications.
Willow Voice supports 100+ languages through its cloud engine with automatic grammar and formatting. EnviousWispr's best engine (Parakeet) is English-only; WhisperKit covers 90+ languages but with higher latency on less common ones.
Willow Voice supports formatting voice commands like "dash," "new line," and "bullet point" natively. EnviousWispr focuses on natural dictation with AI polish handling formatting, rather than explicit voice commands.
If you are Mac-first and care most about privacy, offline transcription, and price, give EnviousWispr a try.
Common questions
Yes. EnviousWispr offers on-device transcription on Apple Silicon Macs, completely free, with no account, no word limits, and no subscription required. It works offline and keeps your audio on your device.
Yes. No subscription, no usage caps, no word-per-week limits. Willow Voice's free tier caps you at 2,000 words per week. EnviousWispr has no such restriction. The source code is available on GitHub under a BSL 1.1 license.
Willow Voice is cloud-based and requires an internet connection for transcription. EnviousWispr was built on-device from the start. Parakeet TDT and WhisperKit run natively on Apple Silicon, delivering 0.43s median latency without any cloud dependency.
Transcription runs entirely on-device and works without internet. AI polish requires an LLM; you can use a local model for fully offline operation or bring your own API key for a cloud provider.
No. Your audio is processed on your Mac and discarded after transcription. It never leaves your device, so it cannot be used for anything else.
Yes. Download EnviousWispr, set your hotkey, and start dictating. There is no data to migrate. Both apps work in any text field on macOS. See the 2-minute getting started guide.
Any Mac with Apple Silicon (M1 or later) running macOS 14 Sonoma or newer. The Neural Engine on Apple Silicon is what makes on-device transcription fast.
Transcription is always on-device. If you choose to enable AI polish with a cloud provider (OpenAI, Gemini), only the text transcript is sent using your own API key. You can also polish with a local model for fully offline operation. The choice is yours.
Source-available under the Business Source License 1.1. That means you can read, build, and inspect every line of code on GitHub. It is not an OSI-approved open source license, but it gives you full transparency into how the app works. Contributions are welcome.
EnviousWispr automatically strips filler words (um, uh, like, you know) from transcripts before they reach your text field. This happens at the post-processing stage, before AI polish, so even without an LLM enabled your text comes out clean.
EnviousWispr saves your clipboard contents before pasting transcribed text, then restores them afterward. Whatever you had copied before dictating is still there when you press Cmd+V next.
