GrabCanvas captures any region, window or scrolling page, then lets you add arrows, numbered steps, highlights and blur. Record your screen to MP4 or GIF with mic and system audio. Copy text you can't select with on-device OCR. Each step marker becomes a line in a written guide you can export to Markdown, Word, HTML or PDF. Windows, macOS and Linux. No account, captures stay on your computer. $29 once, and the first 100 users get a free license.
