Ask a buying team where a creative lives and you get four answers. The final cut is in Frame.io, the raws are in Drive, someone put the resized statics in Dropbox, and the version that is actually running was uploaded straight into an ad account nine weeks ago by a freelancer who has since moved on.
That scatter costs real money. Assets get re-uploaded to every account instead of reused. Client export filenames leak into live ads. Nobody can find the hook that worked in March, so the team reshoots it. And the round trip from an approved cut to a running ad involves downloading a file just to upload it somewhere else.
The Koast creative library is the fix, and it is deliberately not a general purpose asset vault. It is the shelf your launches pull from: assets land here from wherever your team works, get cleaned and grouped on arrival, and go out to Meta from the same screen.
What the library does
Video and statics together
Hooks, UGC cuts, statics and their resizes sit in one library rather than one folder per platform and one more per client.
Your sources, wired in
Upload from your computer, or import from Google Drive, Dropbox and Frame.io. The file moves without anyone downloading it first and re-uploading it somewhere else.
Sizes grouped on arrival
Drop the 9:16, 1:1 and 4:5 exports of the same hook together and Koast detects the sizes and stacks them into one placement-ready ad instead of three loose files.
Files cleaned before Meta
Export filenames and EXIF junk are stripped and names are locked to your convention, so a client-facing export name never ends up attached to a live ad.
Reused, not duplicated
The same asset ships into several ad accounts on one post ID, so engagement compounds on one post instead of splintering across a copy per account.
Fed by the pipeline
Work approved on the creative board lands in the library on its own, so the shelf fills as your team ships rather than because someone remembered to file things.
From upload to live ad
Four steps. After the first one, the library keeps itself current.
Connect your sources
Link Google Drive, Dropbox and Frame.io once. Editors keep working in the tools they already use and their output becomes available to the buyers.
Bring the creative in
Upload from your device or import a batch from a connected source. Multiple files land at once and you watch them come in rather than babysitting one dialog at a time.
Grouped and cleaned
Sizes are detected and grouped into placement-ready ads, metadata is stripped, and names are rewritten to your convention. No manual renaming pass before launch.
Launch straight from the shelf
Pick the assets, pick the destination accounts, apply a launch template and publish the batch. The asset can go out again next week to a different account without being re-uploaded.
Finding the creative worth running again
A library is only useful if you can tell which shelf is worth reaching for. Koast reads live performance across your accounts, so the question is answerable in the product rather than in a spreadsheet somebody rebuilds each Monday.
Ask the agent to find your creative winners and it works from real spend, CTR and results across the portfolio. Ask it to audit creative fatigue and it reads CTR and frequency, flags the ads that are wearing out, and drafts the swap for you to review. You keep the decision. The library keeps the raw material ready so acting on that decision is a batch launch, not a scavenger hunt.
Questions
What kind of creative can I store?
Video and static image ads, including the vertical, square and portrait resizes of the same concept. Koast groups those resizes into a single placement-ready ad rather than treating them as unrelated files.
Do I have to download from Drive, Dropbox or Frame.io first?
No. Those sources are connected integrations, so a file moves from the folder into Koast and out to Meta without a download and re-upload in between.
Can I identify my best performing creative from inside Koast?
Yes. Performance across every connected account is visible in the portfolio view, and you can ask the agent to surface creative winners or audit fatigue and draft the swap for your review.
If I run one asset in five accounts, do I split the engagement?
No. Koast publishes on one post ID across the accounts in a batch, so likes, comments and shares accumulate on a single post.
Will my export filenames show up on the live ad?
No. Filenames and EXIF metadata are stripped and names are locked to your convention before the file reaches Meta.
Who on my team can add to the library?
Anyone you invite with a seat that covers it. Editors and content managers can bring assets in without being added to your Business Manager, and approvals on the creative board can push finished work into the library on their own.
