Edit and annotate

What makes Supademo's screenshot editor different

AI edits text directly inside the image
Most editors let you paste a text box on top. Supademo uses AI to modify existing text inside the screenshot, so the result looks native, not layered. No masking, no Photoshop, no re-capturing.

Blur and redact in one click
Select any area and apply blur or hard redaction instantly: passwords, API keys, pricing, internal UI. The result looks clean and intentional, not like something slapped over the content.

Share as a live link, not a file
Generate a shareable link instead of attaching a PNG. Edit the screenshot later and the link updates automatically. No stale files, no re-sending, no version confusion.
