AI Short Video Generator

AI short video generator for
TikTok, Shorts & Reels

One sentence in, one vertical video out — script, voice, visuals and subtitles already in it. Upload it as it is, or let Easer post it for you.

One free video to start. No credit card required.

One file, and it fits all three

There is one render, not three cuts. The three surfaces want the same shape — vertical, sound on, subtitles legible with the interface over them — so what comes out uploads to any of them unchanged.

PlatformWhat it needsWhy the same file worksEaser can post it
TikTok9:16, sound on, no reformattingVertical full-screen is the native shape, and the audio is generated with the video rather than added over it.Yes
YouTube Shorts9:16, under 3 minutesEvery format here lands well inside the Shorts ceiling, so an episode uploads as a Short without being cut down.Yes
Instagram Reels9:16, caption safe areaSubtitles are burned inside the frame rather than at the very bottom edge, which is where Instagram's own interface sits.Yes

Reddit and X can be connected too. Posting is always a step you take after watching the video, never part of generating it.

From one sentence to something postable

You read the whole thing as text before any of it is rendered

1

Describe it once

One sentence. You get a plan and a full screenplay back as text, and you read them before a frame is rendered.

2

It gets made

Script, voice, shots and burned-in subtitles come back as one finished 9:16 file. There is no timeline to edit and nothing to reformat.

3

Post it, or let Easer

Download it and upload it yourself, or connect an account and have Easer publish on your behalf — TikTok, YouTube, Instagram, Reddit and X.

Short-video questions

What format are the videos?

One 9:16 vertical file with the subtitles already burned in, which is the native shape on TikTok, YouTube Shorts and Instagram Reels alike. There is nothing to reformat and no second export — the same file is what you upload to all three.

Does it make a different version for each platform?

No, and it is worth being straight about that: there is one render, not three cuts tuned to three algorithms. The three surfaces want the same thing — vertical, sound on, subtitles legible without the interface covering them — and that is what comes out. What changes per platform is where you post it, not the file.

Can it post to my accounts for me?

Yes. Connect an account and Easer can post on your behalf to TikTok, YouTube, Instagram, Reddit and X. Posting is a separate step from making the video, so nothing goes out until you have watched it.

How long is a short, and how many can I make?

Between 30 and 120 seconds depending on the format you pick — all of it inside the Shorts and Reels limits. There is no daily cap; it comes out of your credit balance, and Standard's 1,200 credits a month is up to 19 full-length episodes. Video is billed by the second, so shorter ones go further.

Do I need to appear on camera, or record anything?

No camera and no microphone. The performer, the voice and every shot are generated, and new accounts start with 10 credits — enough to read a whole plan and screenplay before paying to render any of it.

Do I own the content?

Yes. Videos generated on a paid plan are yours to monetise, repost or use commercially. Free-plan downloads carry a watermark; upgrading removes it from everything you have already made, not just from new videos.

Will it help me go viral?

Nobody can promise that, and a tool that gives you a number is guessing about your audience. What it removes is the reason most people stop: the cost of making the next one. The hooks, pacing and length are written for the short-form shape, and the rest is what you choose to make and how often.

Is this the same as making a series?

It is the single-video end of the same production line. If what you want is one video about one idea, start here. If you want the same person turning up again next week, that is a channel format — the vlog and drama pages below are where those live, and both are built on the cross-episode consistency this page does not need.

When one video is not the thing you want

Make one and see

One sentence in, one vertical video out, ready for TikTok, Shorts and Reels. The plan and the screenplay come back first, and reading them costs nothing.
