Markup.io is a hosted review tool for collecting comments on websites, images, PDFs, and video through a shareable link. It's a clean way to centralize feedback, but it's a SaaS account where review happens on Markup's hosted version of your content. If your need is simpler — open a page, annotate it, send the result — a free browser extension does that without hosting anything.
What is Markup.io?
Markup.io (part of Ziflow) lets you share a link to a website or file and collect pinned comments from reviewers in one place. It supports multiple content types and is aimed at marketing and creative teams running review-and-approval cycles.

Frequently asked questions
Is there a free alternative to Markup.io?
Yes. Highlite is a free browser extension that annotates live web pages with highlights, notes, arrows, and drawings, then exports a screenshot — with no account and no project setup. It doesn't centralize multi-reviewer threads like Markup.io, but it's free for everyday markup.
How is Highlite different from Markup.io?
Markup.io is a hosted review platform: you create a project, share a link, and collect comments on a hosted copy of your content. Highlite is a browser extension that annotates the real page locally, with no account and no hosting. One centralizes team review; the other is fast personal markup.
Can I collect feedback from a client without an account?
With Markup.io, reviewers comment via a shared link tied to your account. With Highlite, the client installs the free extension once and sends back an annotated screenshot — no account, nothing hosted.
Does Highlite support PDFs and video like Markup.io?
No. Highlite focuses on annotating web pages in the browser. If you need to review PDFs, images, and video in one place with approval workflows, Markup.io is built for that.
