In their own words
CHAMELAION LipSync API
CHAMELAION LipSync API takes video and audio input and produces a video with lip movements matched to the audio. It accepts MP4 video and WAV or MP3 audio by public URL or direct upload. Active-speaker detection runs automatically but can be disabled for an individual request. The maker says the model retains speaker identity, speaking style, and expressions while adapting mouth movements to new audio. Listed uses include dubbing and translation, AI avatars, creative ads, and dialogue replacement or personalization. SDKs are listed for Python 3.8+ and TypeScript/Node.js 18+. Requests require a Bearer token or x-api-key header, except at the health endpoint; generation endpoints are limited to 60 requests per minute, and concurrent job limits depend on the plan. Starter is free and includes 24,000 tokens and two minutes of translation and lip sync, with a watermark. Basic costs €4.00 per year and lists 60,000 tokens and five minutes. The maker says its servers are in Europe and users retain ownership of generated videos. Profile views may work when the mouth remains visible; extreme close-ups, side views above 90 degrees, and cropped mouths are difficult cases.
Sync Labs
Sync Labs provides an AI lip-sync API that generates mouth movements matched to video and audio. Its listed models include lipsync-1.9, lipsync-2, lipsync-2-pro, react-1, and sync-3. The introduction lists 512×512 face resolution for lipsync-2 and lipsync-2-pro, and native 4K for sync-3. The models use audio waveforms rather than text and support 29 spoken languages, including tonal languages such as Mandarin and Thai. Use cases include dubbing, localization, personalized video messaging, e-learning, marketing, entertainment, media, and gaming. Developers can use a REST API and official Python and TypeScript SDKs; documented integrations include Adobe Premiere, DaVinci Resolve, ChatGPT, an MCP server, ComfyUI, and ElevenLabs. Inputs include MP4 video and WAV or MP3 audio, provided by public URL, API upload, or media-library asset ID. The free plan provides 3 generations per month, each up to 20 seconds, and no credit card is required. Hobbyist costs $5 a month plus $0.05/sec; paid plans also list usage charges. The service is available via API and web.
