Just shipped a thing. We replaced 5 spreadsheets with one tool that watches Reddit for high-intent posts. AI drafts the DM. We approve and send. Reply rate so far: 14% (vs ~2% on cold email). Building in public 🚀

FAQ

Are these mockups pixel-perfect?

No, they're recognizable approximations. The point is to spot truncation, hashtag rendering, and length issues, not to replicate the exact platform UI. For pixel-perfect screenshots, use the actual platform.

Why does Instagram look truncated at 125 characters?

Instagram displays roughly 125 characters in feed before "...more" appears. Full captions go up to 2,200 characters but only the first 125 grab the eye. We highlight the cutoff.

Why is X truncated at 280?

We default to the Free tier (280 chars). If you have X Premium (4,000) or Premium+ (25,000), use the Character Counter tool to switch tiers.

Is this really free?

Yes. The first 3 "copy formatted text" actions are free; after that, sign up free with Google for unlimited. The previews themselves are always free.
