Free, open-source voice-to-text app for dictation, AI assistant, and voice writing across any app on Windows, macOS, and Linux.
Key features
- Cross-App Dictation: Press a hotkey (Left Ctrl + Left Super by default) and speak — your words type straight into any app: email, editor, or chat, live as you talk.
- Hey Flow Assistant: Say 'Hey Flow' to reply to a message, write an email, or draft a prompt without touching the keyboard; trigger name is renamable.
- Live Translation: Speak Spanish, Hindi, French, Japanese, or any language and get clean English typed at your cursor, running fully on-device.
- AI Cleanup: Strips 'um's and false starts, fixes grammar, and matches a chosen tone (Professional, Friendly, Concise, or custom) so speech reads polished.
- Screen-Aware Answers: One hotkey summons a floating assistant that can look at your screen and answer about the error, chart, or email in front of you.
- Private Memory & Profiles: Separate profiles per part of your day; remembers how you like to work locally without sending data off-device.
- Cross-Platform Downloads: Ships as a Windows installer, macOS build (one Terminal command on first install), and .deb for Ubuntu and Debian.

SubtitleGenerator
SubtitleGenerator
A browser-based AI subtitle generator that flags low-confidence words for fast correction and offers 33 caption styles, with no signup to start.
Key features
- Confidence-Flagged Corrections: Automatically flags every low-confidence word with its confidence percentage so you review only the cues that are actually uncertain instead of proofreading the whole transcript.
- Per-Cue Re-Transcription: Re-runs transcription on a single cue rather than the entire video, letting you fix one misheard name or term without reprocessing the file.
- 33 Caption Styles in Six Families: Ships clean, creator, karaoke, cinematic, pop and branded style families where typography, framing, highlighting and motion are designed together, from Clean Lower Third to Karaoke Fill to Comic Burst.
- On-Device Video Handling: Keeps the uploaded video on your own device through the browser workflow rather than requiring an upload to a media server.
- No-Signup Free Tier: Lets you upload, transcribe, style and export without creating an account, with all 33 styles unlocked from the start.
- Full-Track Translation: Paid plans add translation of the entire subtitle track inside the same editor, so styling and timing carry over rather than being rebuilt per language.
- Multi-Format Export: Exports to eight subtitle formats plus HD video without a watermark on paid plans, covering Premiere Pro, TikTok and YouTube caption workflows.
- Saved Brand Styles: Paid plans allow custom fonts and saved brand styles so a team's caption look stays consistent across every video.
Best for
- Short-Form Social Captions: Add TikTok, Reels or YouTube Shorts captions in a creator or pop style without opening a video editor.
- Podcast and Interview Clips: Caption conversation-paced audio and quickly correct proper nouns and names that transcription models routinely mishear.
- Course and Tutorial Videos: Produce accurate captions for dense explanatory content and screen recordings where technical terms need checking.
- Premiere Pro Handoff: Generate and correct a subtitle file in the browser, then export it in the format an existing NLE timeline expects.
- Multilingual Distribution: Translate a finished subtitle track into additional languages in the same editor to publish one video across markets.
- Accessibility Compliance: Produce reviewed, human-corrected captions for published video so content meets closed-captioning expectations.
