“Is this post, photo or video true before I share it?”

For a post, screenshot or clip: an archived copy of the original as it appeared, the specific claims it makes written out one per line, the published fact-checks and primary sources found for each, a check of its links and the site behind it, and a verdict per claim of supported, contradicted or unknown with the quoted passages and links, saved as a card the person can share instead of the post.
