LipsyncAI.net

LipsyncAI.net is an AI video talk tool that turns portraits and clips into talking videos with matched mouth motion. A focused lip sync tool that pairs a portrait image or an existing video with uploaded or synthesized speech, aiming for steady mouth alignment on humans, cartoons, animals and partly occluded faces.

LipsyncAI.net is a browser-based tool that pairs a still image or an existing video with a voice track and returns a clip where the mouth moves in step with the speech. The workflow is deliberately narrow: pick a mode, supply the visual, supply the audio, and let the model handle face tracking and phoneme alignment. Audio can come from an uploaded MP3 of up to 20MB or from a text prompt that the site converts to speech before syncing, so a script alone is enough to produce a talking head. The tool splits its single-speaker and multi-speaker tabs into roughly two minute runs, while a separate Long Mode page advertises clips up to five minutes. Basic mode is tuned for clear frontal faces; advanced mode is meant for profile shots and cases where hair, hands or a mask partly covers the mouth, with the model inferring hidden movement. Non-human subjects are supported in image mode, which makes mascot and cartoon animal videos viable, though the site recommends detailed scene prompts and an unobstructed, forward-facing mouth for the cleanest output. Practical limits matter before committing. Images cap at 10MB, videos at 50MB and audio at 20MB. Billing runs at 15 credits per second of output, and anything under five seconds is billed as five. Renderings appear under My Creations for review and download. Multi-person lip sync, which would accept two portraits with separate audio files, is listed as coming soon rather than shipping. This sits in the dubbing and avatar class of tools rather than the full generative video space. It does not build scenes or animate bodies; it fixes mouth motion on footage or art you already have. That makes it a fit for explainer producers, localization teams, social creators running recurring characters, and studios that need interview footage corrected without a manual cleanup pass. Anyone expecting a story generator should look elsewhere.
