For your Buffer queue
Last Look reads every post waiting in your Buffer queue and flags what would make you wince once it is live: a dead link, a “tomorrow” that will mean the wrong day, Markdown that shows up as asterisks, a post too long for the network, the same post queued twice. Fix each one in a click. Nothing changes until you confirm.
Trying it needs no sign-in. Or browse a sample queue.

Readers will land on an error page.
Queue times move. At the current slot “tomorrow” means Sat 14 Nov.
X does not render **bold**.
Every link is opened the way a reader would: 404s, server errors, domains that no longer exist, redirect loops, links to localhost.
“Today”, “tonight”, “this weekend”, “Happy Friday” and dates that will already be past, judged at the moment the post goes out, in the channel’s time zone.
**bold**, # headings, [text](links), HTML tags and & codes on networks that print them as typed.
Counted the way each network counts: X weights links and emoji, Bluesky counts what you see, LinkedIn counts every link as 24.
The same or nearly the same text on one channel, and copies across channels at different times.
[link], {{first_name}}, TODO, images without alt text, hashtags cut short by a hyphen.
Every change goes through Buffer’s own API, only when you press confirm, and only on the post you picked. Moved a post? Last Look re-checks every post the move pushed to a new time.
Daily digest, if you want it: tomorrow’s catches every day at the hour you pick, on a private page and a feed for Slack, a feed reader or your inbox. Read-only, off until you turn it on, one click to turn off.
