# Markup.io alternative for AI-made HTML prototypes

Markup.io is a general-purpose annotation tool: people leave comments on websites, images, PDFs and designs. Ollav is specialised: it takes one self-contained HTML file from an AI assistant and adds pinned comments that the assistant can read and act on. Checked November 2026; check each vendor's site for current details.

## Who this is for

You generate HTML prototypes with an AI assistant and want teammates to comment on the running page, then have the assistant apply the changes.

## When to pick Markup.io instead

- You review **mixed material**: PDFs, screenshots and live websites, not just HTML.
- You work with **external clients** and want a tool they may already know.
- The assets are **not generated by an agent** and nothing needs to flow back into code.

## When to pick Ollav instead

- The thing under review is an **AI-made HTML page** and the agent should handle the feedback.
- You want **every version at one link** with the comment history kept.
- You prefer feedback that stays **inside a workspace**, with accountable reviewers.
