The problem

Launch copy is written for the writer.

We write copy that lands with us. The economic buyer reads it differently. The skeptic reads it as flop-bait. The champion reads it as confirmation. Three groups, one draft.

How it works

Four moves. Twelve minutes.

Paste your draft — tweet, email, landing page, changelog entry.

Presume runs it past 200 readers across your ICP.

Get sentiment per cohort, the exact lines that lose people, and the rewrite suggestion most likely to land.

Re-run on the rewrite until the curve looks right.

Sample stimulus

Drop something like this into Presume:

Subject: We're sunsetting the Free tier. Body: After two years we've decided to remove our Free tier. New users start with a 14-day trial. Existing free accounts have 30 days to upgrade or export. We know this is a big change — we made it because the Free tier was being used in ways we never intended, and the support load was making it impossible for us to support paid customers well.

The outcome

Order the copy for the reader who decides.

Get sentiment per cohort, the exact lines that lose people, and a rewrite suggestion that lands harder on the segment that buys.
