The Concepts Tab
Lay out competing thumbnail directions as concept lanes, react and approve, and branch the strongest ones into design.
Concepts is where you shape the different thumbnail directions for a video and decide which ones are worth pursuing. Each concept is one direction — "ranked app cards", "before / after desk", "bold number hook" — and they sit as stacked lanes so your team can compare them at a glance.

A concept lane
Every lane has a header on the left and a strip of image iterations on the right.

The header holds the concept's name and pitch (both editable inline — just click), plus its derived status: Drafting before any design work, Designing once a design sequence exists, and Approved once it clears the approval bar. Team members can react with a heart, fire, or thumbs-down to signal which directions they like.
Drag the handle on the left to reorder lanes, and use New concept to add another direction. You can also let AI draft a fresh concept — name, pitch, and a starter image — from the project's brief.
Drafts and design sequences
The rail on the right is the concept's visual history. It starts as a Drafts sequence — rough passes you upload to try a direction. When a draft is worth taking further, branch it to design: that opens a separate Design from vN sequence, so polished design work stays cleanly separated from rough drafts.

Use the sequence switcher to move between the Drafts and each design branch, and the flag filter to narrow the rail to approved, rejected, or final iterations. Click any tile to open it full-size on the The Iterate Tab tab.
Approvals
Reviewers with permission approve a concept from its lane. A project sets how many approvals a concept needs (in the Brainstorm brief); once a concept reaches that threshold it is marked Approved and the project becomes ready to publish.

When a concept is approved, the Concepts toolbar surfaces a shortcut to mark the whole project Published.
Set concepts aside
Not every direction wins. Use a lane's options menu to archive a concept — it drops into a collapsed "archived" section at the bottom, out of the way but recoverable — or delete it outright. Add fresh directions any time from the bottom of the list.

Common mistakes
Piling every rough pass into one rail
Keep exploratory passes in Drafts, and branch to a design sequence once a direction is chosen. It keeps the rough work and the polished work readable, and it is what designer assignments attach to.
Waiting for a perfect image to add a concept
Concepts are cheap. Add a name and a one-line pitch to stake out a direction — the images can come later on the The Iterate Tab tab.
