Short-form video is where the reach is, and it's also the most painful thing to keep producing. PostOtter handles the whole loop: it creates the video, writes a native caption, and auto-posts it to Instagram and TikTok on a schedule — no editing app, no upload, no reminders.

What gets posted, automatically

Real Reels and TikTok video

Actual 9:16 motion video four days a week on Instagram and TikTok, with on-screen text pulled from the post — not stiff slideshows.

On-brand images the other days

The remaining days are filled with fresh, on-brand images, so every platform gets something every single day.

Captions written per platform

Hook-first on TikTok, story-style on Instagram, short and punchy on X. Never one robotic caption pasted everywhere.

Posted automatically at human times

Everything publishes on its own at natural-looking times across the week — never the obvious :00 or :30.

X included too

Beyond Instagram and TikTok, PostOtter also posts to X — 7 posts a week each, 21 in total.

You stay in control

Every post is a draft first. Swap the video or image, edit the caption, skip it, or let it auto-publish.

Auto-posting Reels and TikTok video

PostOtter generates genuine short-form video sized 9:16 for Reels and TikTok, complete with on-screen text drawn from the post copy. Four days a week each platform gets a fresh video; the other days get on-brand images.

You never open a video editor or upload a file. Once your accounts are connected, the video is created and posted for you on a schedule — the part of Instagram and TikTok that eats the most time, handled automatically.

Captions written for each platform

A caption that works on TikTok rarely works on Instagram, and neither works on X. PostOtter writes each one natively: a strong hook up front for TikTok, a longer storytelling style for Instagram with relevant hashtags, and something short and punchy for X.

Every caption is generated from your brand profile, so the voice stays consistent across all three platforms even though the format changes.

Posted automatically at natural times

Auto-posting only helps if it looks human. PostOtter schedules posts across the week at believable times and deliberately avoids the round-number slots that give automation away.

It also tracks what it has already published and dedupes, so your Instagram and TikTok feeds get a steady stream of varied content instead of the same idea on repeat.
