Postor Content Studio — ranked short clips, carousels, and captions from one long video
Overview

Creating for every platform is a full-time job

A creator posts across Instagram, X, TikTok, Facebook, and YouTube — each with its own format, cadence, and best time to post. Every long video or podcast should become a week of short content, but cutting, captioning, and reformatting it by hand eats the time that should go into creating. And generic AI drafts never sound like the creator.

Postor collapses that work into one workspace. Content Studio turns a single long video or podcast into ranked short clips, carousels, and captions, each scored for virality. A Brand Voice model learns from the creator's own posts, guidelines, and site, so every AI draft reads unmistakably like them — down to the words they love and the ones they avoid.

Around creation sits the rest of the loop: a schedule and best-time heatmap, a team approval flow with client reviewers and comments, trend and competitor radar that drafts from what's breaking out, plain-language AI insights, and an owned Link-in-Bio hub — so one person, or a small team, can run like a studio.

Where it was breaking down

Where creator workflows break down

01
Manual repurposing

Turning one long video into a week of posts by hand is slow, and most of it never gets made.

02
Generic AI voice

Off-the-shelf AI drafts don't sound like the creator, so everything needs rewriting anyway.

03
Scattered tools

Scheduling, approvals, analytics, trends, and link-in-bio live in five different apps.

04
Posting on guesswork

Format, timing, and trends are guessed, not driven by what's actually working.

The system

What it does

Content Studio

Turn one long video or podcast into ranked short clips, carousels, and captions, scored for virality.

Brand Voice

A trained voice model so every AI draft sounds like the creator, with words-you-love and words-to-avoid.

Schedule & best time

A posting schedule with an audience-activity heatmap for the best time to post per platform.

Approvals

A team and client review flow — comment, request changes, and approve before anything goes live.

Trend Radar

What's breaking out in the creator's niche, with one-tap drafting from a trend, sound, or hook.

Competitor tracking & AI insights

Benchmark growth against tracked accounts and get plain-language next actions.

What we built

The whole creator loop in one workspace

Create, plan, grow, and manage stop being five apps. One long video becomes a week of in-voice posts, those posts flow through team and client approval, and trend, competitor, and audience signals feed straight back into what to make next — all off one connected workspace.
