Auto-post to Instagram, TikTok,
YouTube & Facebook from one upload.
Stop re-writing the same post four times. Upload once and BEAR OS auto-posts to every platform — it writes each network's caption, title and hashtags in your brand voice, schedules the best time, and publishes after your approval. You upload; the system does the rest.
One upload in, four posts out
Shipped and working today — no roadmap padding. Here's the exact path from a single upload to published posts.
Drop in one video or image. BEAR OS reads what's in it and pulls the details it needs to write about it.
You get a platform-tuned caption, title and hashtags for Instagram, TikTok, YouTube Shorts and Facebook — each in your learned brand voice, not one caption copy-pasted four times.
Approve the set (or the whole week) and BEAR OS schedules each post to its best time and publishes automatically — through your connected Buffer account today.
Every network gets a format that fits it
Caption + hooks
A strong first line before the truncation fold, line breaks, and a tuned hashtag set.
Punchy & short
A scroll-stopping hook kept short and native to how TikTok captions read.
Title-led
A searchable, title-style first line plus a description that earns the click on Shorts.
Conversational
A slightly longer, community-friendly post written for how Facebook audiences engage.
Here's the honest version: BEAR OS does the writing, formatting, scheduling and approval — and it publishes to Instagram, Facebook, TikTok and YouTube Shorts through your connected Buffer account today, while direct platform APIs are in development. The work you save is everything before the post goes out.
A scheduler waits for copy. BEAR OS writes it.
No four-times rewrite
Traditional auto-posters still make you write every caption. BEAR OS generates each platform's copy from the upload, so "auto" means the writing too — not just the timing.
Best-time scheduling
Approved posts are scheduled to sensible best times per platform and published on your calendar — you don't babysit a queue.
Approval, not autopilot risk
Everything routes through an approvals queue first, so nothing posts in your name that you didn't sign off on. Approve one, approve all, or schedule yourself.
On the flight plan, labeled as coming: direct platform APIs, more networks, and an editable automation builder. Follow progress on the build-in-public log.
Auto-posting FAQ
How do I auto-post to Instagram, TikTok, YouTube and Facebook at once?
Upload once in BEAR OS. It writes a platform-tuned caption, title and hashtags for each of Instagram, TikTok, YouTube Shorts and Facebook in your learned brand voice, schedules each to its best time, and — after you approve — publishes them for you. Today publishing runs through your connected Buffer account; direct platform APIs are in development.
Does BEAR OS write different captions for each platform automatically?
Yes. From one upload it generates a distinct, platform-native format for each channel — a title-led line for YouTube, a punchy hook for TikTok, a caption with line breaks for Instagram — plus a matching hashtag set, all in the brand voice it learned from your real posts. You don't rewrite anything per platform.
Will it post automatically without me approving?
Only if you want it to. By default every auto-generated post lands in an approvals queue where you approve, edit or discard it before anything goes out. You can approve the whole week at once, or schedule items yourself. Every action is recorded in an audit trail.
Which platforms can BEAR OS auto-post to today?
Instagram, Facebook, TikTok and YouTube Shorts, published on schedule through your connected Buffer account. Direct platform APIs and more networks are on the roadmap and labeled as coming — the copy here reflects what ships today.
