Studio-Grade AI Lipsync Dubbing
AI lip sync is the technology that matches mouth movements with speech in generated video, automatically and in real time.
Create spokesperson videos without a camera, localize content into any language, or bring still portraits to life with natural dialogue.
Try Pexo and start creating lip-synced videos in minutes.
How AI Lip Sync Works in Pexo
Forget audio files, timeline editing, or prompt engineering. You describe your creative intent, and Pexo coordinates every detail to bring your vision to life.
Describe Your Video Idea
Type a plain-language description of your video. Tell Pexo who is speaking, what they say, the visual setting, and the desired tone. You can do this through Telegram, WhatsApp, Discord, or directly in the Pexo web app.
Pexo Builds Voice and Sync
Pexo generates the script, selects the ideal voice, produces the audio, and applies accurate lip synchronisation automatically. Behind the scenes, Pexo chooses the best AI models for the task, so you never need to configure anything yourself.
Receive a Polished Synced Video
The delivered video includes accurate lip synchronisation, a matched visual style, and consistent scene continuity. Your video is ready to publish or share, without needing any further editing on your part.
Every Lip Sync Workflow. One Conversation.
Pexo covers the full range of ai lip sync production needs. From single-speaker portrait videos to multi-face scenes and ad variants, you won't need to switch tools or learn new workflows.
Sync Any Face to Any Voice Automatically
Pexo applies accurate lip synchronisation to a single speaker, whether from a reference image or clip. It matches mouth movement precisely to generated or uploaded audio, all without manual keyframing. You describe the character and their delivery style, and Pexo handles the technical sync layer invisibly.
Redub Any Video in a Different Language or Voice
Pexo can replace the audio track of an existing video and re-sync lip movement to the new voice. This works for dubbing into new languages, changing the tone, or re-recording dialogue. You provide the video and describe the new voice or language direction, no audio editing software required.
Speak in a Consistent Voice Across Every Scene
Pexo maintains a consistent voice identity across multiple scenes or video segments, not just for a one-off voice clip. This capability is part of the production pipeline, so you don't need to integrate a separate voice tool manually. Your characters sound the same, every time.
Sync Multiple Speakers in a Single Video
Pexo handles scenes with more than one speaking character, assigning distinct voices and syncing each face independently within the same video. You simply describe who says what, and Pexo manages the per-character ai lip sync logic without additional configuration. It just works.
Generate Multiple Lip Sync Ad Cuts From One Brief
Pexo produces multiple versions of a lip-synced ad from a single creative description. Generate different voices, languages, or messaging angles efficiently. This offers a significant production advantage for marketers and agencies needing volume without proportional effort.
Why AI Lip Sync Agents Outperform Single-Feature Sync Tools
Traditional lip sync tools require you to prepare audio separately, upload files, adjust timing frame by frame, then export to another tool for final production. This fragmented workflow slows output and raises the barrier to entry.
| Traditional Generators | Pexo | |
|---|---|---|
| Input | Requires structured prompts with specific syntax | Accepts plain language, messy notes, bullet points, or full scripts |
| Model Selection | You pick the model manually from a list | Pexo selects the best model for your content automatically |
| Script & Narrative | You write the script yourself before generating | Pexo structures the script and narrative from your raw input |
| Visual Style | Apply a filter or preset per clip | Describe the aesthetic once; Pexo applies it consistently across all scenes |
| Camera Direction | Limited or no camera control | Describe the shot — pan, zoom, aerial — and Pexo executes it |
| Multi-scene | One clip at a time; you stitch manually | Full multi-scene sequences with continuity built in |
| Iteration | Start over to make changes | Say "make it shorter" or "try a warmer tone" and iterate in the same conversation |
| Workflow | You manage every step of the pipeline | Pexo manages the entire production — you just describe and approve |

Creators Who Stopped Fighting Their Lip Sync Tools
"I've tried so many lip sync tools and they all look robotic. Pexo is the first one where the mouth movements actually match the audio naturally. I used it for a product demo with voiceover and my client thought I hired a real spokesperson."
"Lip syncing used to be my biggest headache — I'd record myself ten times just to get the timing right. Now I just drop in the script, pick a voice, and Pexo handles the sync. The result looks clean enough for Instagram ads."
"I make explainer videos in three languages, and re-recording lip sync for each one used to take forever. With Pexo I just describe what I need in the chat, and it generates the video with perfect lip sync automatically. Honestly kind of mind-blowing."
Frequently Asked Questions
How detailed does my text description need to be?
As vague or specific as you like. Pexo reads your intent and asks follow-up questions if anything is unclear. You don't need prompt syntax or special formatting.
Is there a free text-to-video option?
Yes. You can start for free with no credit card required. Free text-to-video generation is available on the starter plan.
Can I control the style, length, and aspect ratio?
Yes. Specify style, duration, and aspect ratio in your description. Or leave it to Pexo to decide based on your content.
Does Pexo write the script too, or just generate visuals?
Both. Pexo generates the narrative structure, visual direction, and voice, and builds the full video from your text. Pexo functions as a complete text-to-video creator, not just a clip generator.
Which AI text-to-video models does Pexo use?
Pexo selects from multiple leading video AI models, including Seedance, Kling, and others, based on what best fits your content type and style.
Can I use Pexo as a text to video app on mobile?
Yes. Pexo works inside Telegram, WhatsApp, and Discord on any device. No separate text to video app needed.
How is this different from other text to video software?
Most text to video software requires prompt engineering and manual model selection. Pexo operates as a creative agent. It interprets your idea, makes production decisions, and delivers a finished video. It's not a tool you configure; it's a partner that thinks with you.
Can I use my own images or clips with text?
Yes. Drop in reference images or existing footage and describe what you want. Pexo uses your assets to guide the result.
