An AI lip sync generator turns a still photo into a video where the person appears to talk, with mouth movements and expressions matched to an audio track. GoCrazyAI animates your portrait from a voice + script and automatically picks the best engine for your clip — no camera, recording, or editing needed.

Upload a clear portrait, pick an AI voice, type a script (add [emotion] tags for expression), choose a length, and click Generate. Your talking video renders in 1–3 minutes in crisp HD and saves to your My Creations, watermark-free.

Yes. Choose from 2,000+ voices across many languages and accents, and the lip movements adapt to the phonetics. You can then localize the finished video into 30+ languages with AI Dubbing.

Yes — switch to the Two persons tab, upload a photo where both people are side by side, and give each speaker their own voice and script (or audio file). Choose who speaks first for a conversation, or have them speak at once for duets. Two-person videos render at up to 720p.

Yes. Pick "Create a Singing Avatar", upload a portrait and a song (make one with AI Music), and the avatar performs it with synced lips and expression — up to 3 minutes long. Full songs render in roughly 10–25 minutes and the video keeps your photo's shape.

Yes. After your video generates, click "Add background music", upload a track (or make one with AI Music), set the volume, and the music is mixed under the voice automatically.

On longer clips, AI talking-video engines can drift from the source face over time. We automatically anchor every generation with identity-preserving instructions, and for the most consistent likeness we recommend keeping clips to 10 seconds or less. Using the same seed reproduces a result but does not by itself lock the face.

No. Talking videos export without a GoCrazyAI watermark and are saved to your My Creations for download. AI-generated media should be labeled where required by law (e.g., EU AI Act).

It runs on pay-as-you-go credits: 15 credits for a 5-second clip, 35 for 10 seconds, 50 for 15 seconds, 95 for 30 seconds, 180 for 60 seconds, 200 for 2 minutes and 280 for 3 minutes (singing). Clips render in HD at no extra cost. You can buy credits as you need them, and they never expire.

Most talking videos render in about 1–3 minutes depending on length and resolution. You can queue jobs and they appear in the shared generation queue used across GoCrazyAI.

Yes, provided you have the rights and consent for the image and your use complies with our Content Policy and applicable law. You are responsible for the likenesses you animate.

Every uploaded image is screened by AI moderation, minors are blocked, and you must confirm you have rights/consent and will not create deepfakes or impersonate real people before generating.
