Redline — Web Annotation & Feedback

About

Screenshot, annotate, and paste feedback to clients or engineers — no account, no subscription.

ZERO UPLOAD
Everything happens on your machine. Screenshots never touch a server — for freelancers under NDA, that's not a feature, it's the baseline.

CAPTURE THREE WAYS
- Visible area — one click grabs what you see
- Region — drag to select, with live dimensions
- Full page — auto-scroll stitching to the footer

CALLIGRAPHIC ANNOTATION (free)
Arrows, boxes, ellipses and freehand with genuine broad-nib ink pressure — real thick-and-thin strokes, not uniform outlines. A nine-color apothecary palette (seven earthy inks plus highlighter yellow & orange). Adjustable stroke width and text size, double-click to edit text, privacy blur, crop, undo, full keyboard shortcuts. Optionally stamp each export with the URL and timestamp. Interface in English, 繁體中文, 日本語, Français and 한국어 — switch anytime.

ONE-KEY DELIVERY
⌘C copies a PNG straight into Slack, email or Notion.

PRO — one-time purchase, up to 3 devices
- Numbered issue pins — click onto the page; each pin holds the problem and the expected behavior, shown in a live iOS-style card and a side overview. (Free: up to 3 pins.)
- Bug report Markdown — one click compiles every pin into a ready-to-paste report, with browser version, viewport and OS attached automatically. Engineers stop asking "what environment?"
- PDF feedback reports — annotated screenshot plus an issues page, ready to send to clients.
- Branded exports — your logo replaces the default corner mark on every PNG and PDF.

Built for everyone who screenshots, circles, and sends — all day, every day.

Requires no permissions beyond the page you choose to capture. The only network request is license activation with Lemon Squeezy (our merchant of record). No analytics, no tracking, no ads.
