# AdPlaybook

> A Mac desktop app that turns a product page into a complete, buildable ad
> campaign — strategy, audiences, exclusions, copy, test matrix and measurement
> plan — then traces every factual claim to a verbatim quote on the user's own
> site and checks the campaign against each platform's published limits before
> anything is spent. Runs locally; no account, no server.

## What makes the ad-spec pages citable

Every character limit, aspect ratio and hard floor on this site is quoted from
the platform's own documentation and carries the URL it came from and the date
it was read. Anything that could not be verified is listed as unverified rather
than omitted. The pages are generated from the same data files the application
reads, so they cannot drift from the product.

Two corrections to figures widely published elsewhere, both checked against the
platforms' own help centres on 2026-08-10:
- LinkedIn introductory text: the maximum is 3,000 characters (150 to avoid
  truncation), not the 600 commonly stated.
- TikTok ad captions: TikTok's own in-feed specification page states no
  character count. The commonly cited 100-character figure appears nowhere in
  their documentation.

## What it deliberately does not do
- It does not generate images or video. It produces a creative brief.
- It does not predict performance or attach a score to an unrun ad.
