# Best MarkUp.io alternative when an agent owns the fix

> MarkUp.io makes contextual feedback easy across websites, PDFs, images, and video. ReviseMy is for when that feedback must become next_action for a coding agent — with a board that separates resolved from verified.

## Why people look for a MarkUp.io alternative

- Comments need to become structured work for an agent, not only a collaborative review canvas.
- You review agent-built UI, email HTML, or slides as often as marketing sites and decks.
- You want authoritative owner marks vs guest suggestions vs optional AI hints.
- Multi-pass agent work needs before/after evidence and a human-only verification gate.

## What to look for

- Whether feedback feeds humans in a review tool or an agent MCP endpoint
- Coverage beyond live sites (screenshots, PDF, HTML) with type-aware checkups
- Whether “done” means comment resolved or human-verified on the board
- Share-link friction for non-technical reviewers without seats

## Worth a look

### Pastel

Share-link annotation on live sites, images, PDFs and video, with an MCP server that lets agents read, reply to and resolve comments.

Best for: Client proofing across many formats, where a resolved comment is enough of a finish line.

- Link-based annotation
- Live site and asset markup
- Client-friendly, low install friction

## When to keep MarkUp.io

- Keep MarkUp.io for creative teams annotating many content types when there is no coding agent in the ship loop.
- Use ReviseMy when the next reader of feedback is an agent on MCP.
- You can keep MarkUp for broad asset review rounds and ReviseMy for agent-built product UI.
- If unlimited collaborators and multi-format creative review are the product — and agents are out of scope — MarkUp may fit better.

## Questions

### Is ReviseMy a MarkUp.io replacement?

No. ReviseMy does not aim to be a general creative review canvas for 30+ file types. It is an alternative when feedback must drive an agent checkup loop with MCP next_action.

### Does ReviseMy annotate live pages like MarkUp?

ReviseMy marks regions on captured screenshots (including URL capture). It is capture-based, not a live multi-format markup product.

### Can I use both?

Yes. MarkUp for classic creative review rounds; ReviseMy when an agent owns the implementation pass.
