Stet is an open-source macOS dictation app that transcribes speech locally and then uses AI to clean up the output while actively preserving your personal writing style and tone. The core innovation is a voice model — a lightweight profile that learns from your past writing so the AI corrections don't flatten your voice into generic AI-ese. The result is meant to sound like you dictated it, not like it was passed through a generic LLM. The technical approach combines local Whisper-based transcription (nothing leaves your device during speech-to-text) with an optional AI refinement pass that can use your own API key (BYOK) or a $6.99/month subscription. The open-source release includes the voice profiling code, making it auditable and forkable. It's a direct response to Wispr Flow, which is closed-source and subscription-only. For writers, podcasters, and productivity users who dictate significant amounts of content, the voice preservation angle is genuinely differentiated. The proliferation of AI writing tools has created a recognizable 'AI voice' — flat, over-structured, and devoid of personality — that sophisticated readers are increasingly adept at detecting. Stet's bet is that preserving your actual voice is the most valuable thing an AI writing assistant can do.

Wispr Flow converts speech to polished text at ~220 words per minute — about 4x average typing speed — with AI-powered editing that strips filler words and fixes transcription errors automatically. It works across 50+ apps including Gmail, Slack, VS Code, and Notion, supports 100+ languages with auto-detection, and syncs across Mac, Windows, iPhone, and Android. The company has raised $81M total (including a $30M Series A in mid-2025), acquired Yapify in December 2025, and just expanded to Android. It's currently #1 on Product Hunt today with 2,129 upvotes.
Reviewer scorecard
“Open-source, local-first transcription with BYOK is the right architecture. I've been burned by voice tools that upload my audio to servers I can't audit. The voice profile approach for preserving style is technically interesting — I want to see how it handles domain-specific jargon and code-switching between formal and casual registers.”
“Wispr's VS Code integration actually works — I've been dictating code comments and docstrings and it handles technical vocabulary surprisingly well after a few sessions of training. The cross-app context awareness (adjusting tone for Slack vs email) is subtle but real. For any developer who types a lot of prose, this is a legitimate productivity gain.”
“The 'sounds like you' promise needs a lot of data to actually deliver — your voice profile is only as good as the writing samples it's trained on, and most people don't have a consistent, large corpus of their own writing. For casual dictators, this might just be Whisper with extra steps. Apple's built-in dictation is free and surprisingly good now.”
“At $81M raised, Wispr has a significant burn problem given free tier competition from native OS dictation and Apple Intelligence. The core transcription accuracy isn't dramatically better than free alternatives for English speakers, and the 'AI editing' layer adds latency. The pricing tiers aren't transparent on the website, which is a red flag for a recurring subscription product.”
“Voice-first computing is coming back, and the arms race for authentic AI writing assistance is heating up. The distinguishing factor won't be transcription accuracy — everyone has solved that — it will be voice fidelity. Stet is building in the right direction: local processing plus personal style models. Expect this architecture to be standard in two years.”
“Wispr isn't just a dictation tool — it's positioning for the voice OS layer. The Yapify acquisition, the cross-device sync, the app-aware formatting: this is infrastructure for a future where voice is the primary input modality. The 100+ language support makes it globally viable. $81M is not too much for that bet if they execute.”
“This is genuinely exciting for writers and content creators. The homogenization of AI-assisted writing is a real aesthetic problem — everything starts sounding like the same LinkedIn post. A tool that actively fights that tendency by learning your specific voice is solving the right problem. Even if the voice model needs work, the direction is exactly right.”
“As someone who writes a lot of copy, Wispr's filler word removal and auto-polish is genuinely freeing — I can think out loud without editing as I go. The Personalized Style feature is underrated: it learns your voice and keeps outputs consistent across apps. The Android launch (finally) makes this a real daily driver.”
