How it works

From media to live in three steps

The same composer your team uses by hand is the one your AI agent calls through the API. One flow, two operators.

01

Pick your content

Choose from a reusable media library. Every asset carries AI understanding — transcript, summary, and topics — ready to power your copy.

video
02

Choose platforms

Select destinations and the exact post type for each — long-form or Shorts, video or photo, Reel, image, or carousel.

Shorts Video Reel
03

Schedule or publish

Let AI draft per-platform copy, preview the live post, then schedule it on the calendar or publish now. Approvals optional.

Generated by AI
Everything in one place

A publishing workspace that does the heavy lifting

The 3-step composer

Content → platforms → details. Per-platform titles, captions, descriptions, tags, and thumbnails, with a live preview of every post before it goes out.

YouTube TikTok Instagram

AI that writes the copy

Generate titles, captions, descriptions, and hashtags — for one platform or all of them — straight from your media.

One calendar & queue

See every scheduled post at a glance. Quick-add from any day, reschedule by drag, edit until it publishes.

Reusable media library

Upload once, post forever. Archive, restore, and reuse assets across every campaign and platform.

Approvals & status

Drafts, approvals, scheduled, published, failures — with retries and a full timeline. Nothing slips through.

For operators & AI agents

Give your agent a key.
Keep yourself in the loop.

A private API lets your AI agent upload media, draft posts, and schedule or publish — while approval mode keeps a human in control of anything it creates.

Scoped, hashed tokens
Raw token shown once, granular scopes, expiry, and instant revocation — with a full usage audit trail.
Approval mode
Flip one switch and every AI- or API-created post waits for your one-tap approve or reject.
Reliable delivery
Native publishing adapters, readiness checks, and automatic retry surfacing for every platform.
POST /v1/posts
# Your agent drafts a post — approval mode keeps you in control
curl https://api.seamless.social/v1/posts \
  -H "Authorization: Bearer ss_live_•••" \
  -d platforms="youtube,tiktok" \

  -d generate="title,caption,hashtags" \

"Our agent drafts the week's posts overnight and I approve them with coffee. What used to be a full afternoon is now ten minutes."

Maya Okafor
Creator, Lumen Studio
★★★★★

"We manage 14 client accounts. The calendar and approval flow are the only reason that's even possible without a bigger team."

Dev Raman
Founder, Pace Creative
★★★★★

"The API just worked. Scoped tokens, approval mode, real error states — it felt built by people who actually ship to these platforms."

FAQ

Questions, answered

YouTube, TikTok, and Instagram — natively, with the right post types for each. LinkedIn, Facebook, X, and Google Business are on the roadmap.
Your agent uses scoped API tokens, and approval mode means anything it creates lands in a review queue. You approve or reject with one tap before a single post goes live.
Both. Generate titles, captions, descriptions, and hashtags from your media for one platform or all of them — then edit anything before scheduling. You always have the final word.
You'll get an alert with the exact provider error and a one-click retry. The status page tracks drafts, approvals, scheduled, published, and failures with a full timeline.
Yes — anything scheduled is fully editable until the moment it publishes. Reschedule from the calendar, change copy, or cancel entirely. Past posts stay read-only.

Start publishing in minutes.

Connect your accounts, upload your media, and let Seamless Social — and your AI agent — take it from there.
