Plaintext
Turn Plaintext snippets into images worth sharing, without leaving your Mac.
Sometimes the right answer is no highlighting at all — log output, a stack trace, a config dump, or anything where invented colour would imply structure that is not there.
Codeshot detects Plaintext from the code you paste, so there is no language picker to get wrong. Here is the same snippet in three of the 30 themes it ships with, rendered with the app's own stylesheets.

[2026-08-01 11:04:23] saved ~/Desktop/snapshot.png (412 KB)Choose Plain text explicitly rather than letting detection guess. Auto-detection on unstructured text will find a language eventually, and colour it misleadingly.
Let the image follow your content, or lock it to a ratio — 1:1, 4:3, 3:2, 16:9, 9:16, 2:3, or 3:4 — then export at 1×, 2×, or 3× so it stays sharp on a retina display. Copy it straight to the clipboard with ⌘⇧C, or save with ⌘S.

Everything runs on your Mac. Your code never leaves it.
