SyncVocal is a free teleprompter that scrolls as you speak. It listens through your browser's speech recognition and keeps your script in step with your voice, in 30 languages. It comes as a Chrome extension that floats over Google Slides and reads your speaker notes, and as a web app at syncvocal.com. It can also draft a spoken script from your slides with AI.
Yes. Voice sync is free in 30 languages with no time limit. The free plan also includes Camera Mode, mirror mode, file import (.txt, .md, .srt), one free AI script draft, and up to 5 scripts saved to your account. No credit card required. Pro is $15 a month for 10 AI credits, unlimited saved scripts and .docx import.
Not for the Chrome extension: install it and voice sync works over Google Slides with no account. The web app at syncvocal.com/app needs a free account (Google or email, no credit card), which also saves your scripts across devices. AI script drafting needs an account too.
Voice sync uses your browser's built-in Web Speech API (the same technology behind Chrome's voice search). When active, your browser sends audio to Google's speech recognition servers. The prompter scrolls automatically as it recognizes your speech.
Yes. Scripts stay in your browser by default. If you click Save to My Scripts, that script is stored on our servers so you can open it on other devices. We don't share it or use it to train AI. If you use an AI feature, the script is sent to that AI provider to process it. See our Privacy Policy for details.
Free accounts can import .txt (plain text), .md (Markdown), and .srt (subtitles). Pro also imports .docx (Word). PowerPoint files aren't supported directly; upload the deck to Google Slides and use the Chrome extension instead.
Open your deck in Google Slides, click the SyncVocal extension, and choose Draft my script with AI. It reads your slides and speaker notes, asks a few short questions about your audience, length and tone, then writes a spoken script with one section per slide. Your first draft is free with a SyncVocal account, and Pro includes 10 AI credits a month. You can also use your own OpenAI, Claude or Gemini API key, with no limit and no credits used.
Partly. Once the app is open, speed-based auto-scroll keeps working without a connection. Voice sync needs internet, because your browser's speech recognition runs on Google's servers. AI features also need internet.
Not directly. The Chrome extension works with Google Slides. To use a PowerPoint deck, upload it to Google Slides first, or paste your notes into the web app.
Yes! Install the Chrome extension and it auto-detects Google Slides presentations, extracts speaker notes, and displays them in a floating teleprompter window with voice sync. Perfect for presentations and lectures.
Camera Mode is a floating, always-on-top window that you can position next to your webcam. It's perfect for YouTube videos and video calls — read your script while looking straight at the lens.
The web app works on mobile browsers, but the Chrome extension is desktop-only. Voice sync and Camera Mode work best on desktop.
Voice sync works in Chrome, Edge and Safari. Firefox doesn't support browser speech recognition, so it gets speed-based auto-scroll only. The Chrome extension runs in desktop Chrome and other Chromium browsers.
