FastLipsync

FastLipsync is an AI tool that automatically matches a character's mouth movements to spoken audio in a video. It is used for video marketing, multilingual dubbing, and social media shorts, working with both real people and virtual characters.

A user uploads a talking video and a separate audio file, each up to 60 seconds, then generates the result with one click. The AI analyzes the audio and video to sync lip movements naturally, matching audio and video durations automatically by looping a shorter video or trimming a longer one.

FastLipsync delivers precise, natural lip movements regardless of face angle, facial hair, or subtle mouth motions, and works with mp4, mov, and webm video formats. It can translate audio into another language and resync the lips to match, and generated videos can be downloaded in high quality for personal or commercial use.

Plans are billed monthly or yearly, with a 20% discount for yearly billing: Starter at $8 per month with 600 credits, Pro at $16 per month with 1,500 credits, and Premium at $48 per month with 6,000 credits. Every plan includes commercial use license, private generation, priority support, and the option to cancel anytime.
