Add a voiceover to your video.

Let me be specific, because a lot of tools blur this. This is not a tool that makes a video for you. You already have the video. Maybe you filmed it, maybe you screen recorded it, maybe a designer handed you a motion graphics clip. The picture is done. What is missing, or what is wrong, is the voice. That is the one thing this fixes.

So you upload the clip. You paste in the script, the actual words you want spoken over it. You pick who says them from 400+ voices. And we generate that narration and lay it straight onto your footage, lined up to the exact length of the clip, then hand you back a single finished MP4. The frames you shot never change. Only the audio riding on top does.

Here is the part people miss until they have felt the pain. Making an AI voice is the easy half. Loads of tools do that and spit out an MP3. The hard half, the half that quietly burns an hour, is getting that audio onto the right video, starting at the right moment, ending without running off the cliff, exported as one file. We do that half for you. That is the difference between an audio generator and this.

And the voices are not the flat robots from a decade ago. They breathe. They pause where a person would. They put weight on the words that matter, mostly. Not perfect, they still fumble a strange acronym here and there, but good enough that most viewers never notice, and a hundred times better than dead air or a block of text sitting on the screen.

Here is how this normally goes, and you have probably lived it. You write the script in one place. You paste it into a voice tool and download an MP3. You open a video editor, drag your clip onto the timeline, drag the MP3 onto an audio track underneath. Then you scrub back and forth, nudging the audio so the first word does not land while the screen is still black. The narration runs a few seconds long, so you either speed it up by hand or trim a sentence. You lower the original audio if you want to keep the music. Then you export. Then you realize the level is off and you do it again.

That is four tools and a lot of patience for what should be one step. And the worst part is the sync. Your AI voice almost always comes out three to five seconds shorter or longer than the clip, and there is no button anywhere that says "just make this fit the video." So you do it by hand, every single time, for every single video.

We took that whole shuffle and turned it into one screen. Upload, paste, pick a voice, choose replace or talk over, hit go. The fitting happens for you. No editor to learn, no tracks to align, no export settings to second guess. You came here with a video and a script. You leave with a voiced video. That is the entire job.

This is the bit that quietly matters most, so let me spell it out. Before we generate a single word, we read how long your clip actually is. Then we shape the narration to land inside that window. If the read comes out a hair long, we tighten the pace, but only inside a range that still sounds like a person talking, never the chipmunk speed-up you get from cranking playback rate in an editor. If it comes out short, we pad the end with a beat of quiet so the audio settles instead of slamming to a stop.

And if your script is just way too long or way too short for the clip, we do not silently ship something awkward. We tell you, right there, so you can trim a sentence or add one. No surprises after the fact, no re-uploading three times to figure out why it feels off.

That is the feature people search for without knowing the words for it. "Make the voiceover match my video length." Nobody owns it because almost nobody built it. We did, because it is the exact thing that turns a ten minute editor chore into a non-event.

This is the use case that pays for itself fastest, so it gets its own spot. You made one good video in English. Your audience is not all in English. Normally that means hiring a dub studio, or filming the whole thing again with a different presenter, or just giving up on those viewers. None of that is fun, and two of those are expensive.

Here it is three steps. Upload the video you already have. Paste the script in the language you want, you can run it through a translator first, and tidy up the names and slang so they land right. Pick a voice that actually speaks that language, not an English voice forcing its way through foreign words. Hit go. Now you have a Spanish version, or a Hindi version, or a Japanese version, off the exact same footage, in the time it takes to make a coffee.

We have 75+ languages, so the same clip can become five or ten cuts for different markets without you touching a camera. It is not lip synced, the mouths still move in the original language, so for a tight closeup of someone speaking it reads as a dub. For everything else, screen recordings, tours, demos, B roll, voiceover-led marketing, nobody is staring at lips anyway, and the new voice just makes the video make sense to a whole new audience. The dubbing market is growing fast for exactly this reason. It is the cheapest reach you will ever buy.

Formats are the usual ones. MP4, MOV, MKV, and WebM. That covers basically anything off a phone, a screen recorder, or an editor export. The length you can run depends on your plan, and I am going to be straight about it because hidden caps are the worst part of "free" tools.

The free taste handles a short clip, up to about thirty seconds, so you can hear the quality and see the flow before you spend a cent. PRO opens it up to five minutes a video. Creator goes all the way to thirty minutes and a one gigabyte file, which is more than enough for any Short, Reel, demo, tour, lesson, or listing video you are likely to make. If you are trying to voice a feature-length film, that is not what this is for, and our PDF to audiobook tool is honestly a better road for book-length work.

The biggest one, by a mile, is a script that has nothing to do with the clip length. People paste two hundred words of narration onto a fifteen second video and wonder why it feels like a race. The fix is boring but it works. Watch your clip once, time it in your head, and write to that. If you are way over, we will tell you before we render, so listen to that warning instead of forcing it.

Second one. Picking the first voice in the list and never trying another. The default is fine. It is not always right. A bored corporate voice on a hype reel kills the energy, and a hyper voice on a serious explainer feels fake. Audition a couple. It takes thirty seconds and it is the single thing most likely to make people stick around.

Third. Forgetting to choose replace or talk over and then being surprised by the result. If your music vanished, you were on replace. If the new voice is fighting the old audio, you wanted replace and got talk over. It is one toggle. Glance at it before you hit go.

And the last one is expecting the mouths to move with the new words. They will not. This is a voiceover, not a face reshaper. For screen recordings, demos, tours, slideshows, and faceless content you never see a mouth, so it does not matter at all. For a talking-head closeup where the lips are dead center, a different voice on top reads as a dub, which is fine for some things and odd for others. Know which one you are making before you upload.
