Lip Sync AI addresses a specific and stubborn production problem: making a face on screen look like it is actually saying the words you hear. Instead of animating a cartoon avatar, the platform works on real footage. You upload a video (MP4, MOV, AVI, WebM, MKV) or a photo, supply an audio file or reuse the clip's existing soundtrack, and the model regenerates the mouth region so the performance lines up with the new audio. It supports multiple faces in one frame, so panel discussions, interviews, sketch comedy, and mini-dramas with several speakers can all be handled. The tool also claims tolerance for challenging angles — profile views, tilted heads, beards, and subtle mouth movement.
The workflow is deliberately short. Pick your video and audio source, choose between a fast Standard mode and a higher-fidelity Precision mode, tell the tool how many faces to sync and which ones to target, then preview and download. Alongside the core syncing engine, the site bundles a text-to-speech tool and an AI song generator, which means you can create a voice track from scratch and sync it without leaving the app — useful for dubbing old footage or producing content in a language you do not speak.
Pricing follows a freemium model. The free tier is genuinely usable but constrained: uploads are trimmed to roughly ten seconds of video and one second of audio until you upgrade. The site does not publish exact paid tiers on its landing page, so check the in-app pricing screen for current credit packs and limits. The main appeal is speed and accessibility — it removes the need for manual mouth animation, avatar pre-recording, or a video editor, and puts multi-language dubbing and content repurposing within reach of solo creators.
