Visemix is an AI lip sync tool that takes a video of a person and a separate voice track, then regenerates the mouth movement to match the new audio. The face, background and framing stay as they were. It suits creators redubbing their own footage, teams localising approved videos, and anyone making short talking clips. Our read: the privacy design is the best thing here, but the credit maths gets expensive fast and several advertised features are not actually released yet.
What Is Visemix?
Visemix runs at lipsync.vip and does one job: AI lip synchronisation. Its own guide draws a useful distinction. This is not fixing audio delay in a video, and it is not miming. The AI regenerates visible mouth motion from a separate voice track while keeping the person, background and frame intact.
The product is built around a local-first idea. Before any file leaves your machine, the browser checks format, file size, duration, resolution and audio timing. That check is free, uses no credits, and uploads nothing. Only when you sign in and press Generate does anything reach a server. Target users are creators redubbing their own talking-head footage, marketers updating approved campaign videos, and educators adding clean narration to lessons.
How Does Visemix Work?
Step one is your source. Upload an MP4, MOV, WebM or M4V clip up to 120 seconds, or pick a portrait photo, or start from one of three sample avatars. Photo mode accepts JPG, PNG, WebP, AVIF, HEIC, GIF, BMP and TIFF, with unusual formats converted in the browser first.
Step two is the voice. Upload an MP3, WAV, M4A or WebM file up to 120 seconds, record straight into the browser, or type text and use speech synthesis. You also pick a quality level and a language.
Step three is generation. The system estimates credits from your audio duration and chosen quality, reserves them, then runs the job. Standard costs one credit per second of audio. Pro costs four times that and Ultra seven times. Adding a background costs two more credits. If a job fails, the reserved credits come back automatically.
Key Features

Performance and Experience
The local check is genuinely useful. Most lip sync tools take your upload, spend your credits, then tell you the result is poor. Visemix catches format and timing problems before either happens, which is a real workflow improvement rather than a marketing line.
On output quality, the company is fairly candid. Its own guidance says results depend on a clear, well-lit, mostly front-facing speaker with visible lips, and it names side profiles, multiple speakers, fast head turns and mouth occlusion as harder cases. It also warns that singing is harder than speech because long vowels and rapid syllables demand more complex mouth shapes, and that outputs may still show blurry lips, teeth artifacts or unstable frames.
That honesty is welcome, but there is no independent evidence either way. No listing on G2, Capterra, Trustpilot or any app store currently covers Visemix, and no third-party comparison includes it. Treat quality as unproven.
Integrations and Compatibility
Everything runs in a browser, so it works on Windows, macOS, Linux, Android and iOS with nothing to install. Audio can be recorded directly in the page, which removes one round trip for quick clips.
Past that, the plan comparison table is blunt about what is missing. HD output, batch processing and API access are all marked as excluded from every current plan. Public sharing is disabled by design. There is no mobile app, no browser extension, no editor plugin, and no export beyond the downloaded video. Anyone building lip sync into a pipeline has nothing to connect to.
The Verdict: Strengths, Weaknesses & Value
Two decisions here deserve credit. The local preflight is the right answer to a real frustration, and refusing to watermark trial output is unusually generous in a category where the free tier normally exists to sell you a watermark removal. Returning credits on failed jobs and storing results privately behind signed links both point the same direction.
The pricing is where enthusiasm should stop. Creator costs $19 a month for 300 credits, which is five minutes of Standard output. At Ultra quality those same credits buy about 43 seconds. Worse, subscription credits do not roll over, so an unused month is simply gone. Only the one-time packs have credits that never expire, and those come with 1 GB of storage and a single concurrent job.
Add the missing HD, batch and API, the 120 second cap, and three headline features still behind availability language, and Visemix reads as an early product with good instincts in a very crowded market. The privacy design is the reason to try it. The credit maths is the reason to test with a one-time pack before subscribing.
Suggestions For Improvement
- Let subscription credits roll over, or state clearly at checkout that they expire monthly.
- Ship  AI Dubbing, Talking Photo and text-to-speech, or remove them from the marketing until they are live.
- Add HD output, since no plan currently offers it.
- Publish typical generation times so buyers can judge the concurrency limits.
- Offer a small free trial generation so quality can be judged before purchase.
- Get listed on an independent review platform so quality claims can be verified.
