Compare creators on post performance before you pay them

I want an app for deciding what to brief a creator on before we pay them, built around post level data instead of follower counts. It is an Instagram only view, and I want that stated clearly in the interface, because the post level media data I am relying on does not cover TikTok. Do not imply multi platform coverage anywhere in the app.

The starting surface is a saved handle list. I add the Instagram handles of creators we are considering, the list persists between visits, and I can remove handles or leave a short note on each one. From that list I either select a single creator to open in detail, or select two or three to open compare mode.

The creator detail view calls HypeAuditor's Get Instagram Account Media, which returns post level likes, comments and engagement rate along with pre ranked top and bottom buckets. Show the top performing posts and the bottom performing posts side by side in two columns, one card per post, each card carrying likes, comments, engagement rate and the post date, with a link out to the post itself. The whole point is to see at a glance which formats land and which fall flat for that creator.

Every post needs a baseline to be measured against. Call HypeAuditor's Get Instagram Report for the creator and use the account level engagement rate from that report as the baseline. Show each post's engagement rate as a difference against that baseline, so a post reads as above or below what that creator normally does rather than as a bare number with no context.

Compare mode puts two or three selected creators next to each other on the same metrics, one column per creator, with the top and bottom buckets stacked inside each column. Each creator gets their own baseline from their own Get Instagram Report, so the comparison stays fair across accounts of very different sizes.

Flag posts that are unusually old. If a post in either bucket is much older than the rest of the sampled set, or older than a configurable age threshold, mark it with a visible stale badge and say why it is flagged, so nobody builds a brief off content that no longer represents what the creator is making today.

Add an Analyze content patterns button that starts a background agent over the currently selected creators. The agent reads the top and bottom buckets for each of them, works out which hooks, formats and posting cadences correlate with the wins and which correlate with the misses, and writes a creative brief. It creates the document with Google Docs Create Document, then fills it in with Batch Update Document, structured into sections such as what works, what to avoid, recommended formats, and posting cadence, citing the specific posts it drew each conclusion from. When the run finishes, store the document link back in the app so the creator or comparison it came from shows its briefs and links straight out to the doc. Show run status while the agent is working.

Add a Share button that posts the headline findings to Slack using Send a Message. Let the user pick the channel, and include the creators covered, the two or three strongest takeaways, and a link to the Google Doc brief.

Be careful with HypeAuditor usage. Report calls consume credits from the account's plan, so the app should save what it has already fetched and only refetch when the user explicitly hits refresh, rather than reloading creator data on every page view. Also handle the case where a report is still being generated and needs a retry after a short wait, and surface a clear message when an account is private or cannot be reported on.
