How to choose

Which platforms does it need to run on?

Choose a tool that matches your workflow: options on this board run on the web, through an API, as a browser extension, on iOS or Android, and on Windows.

Web access suits browser-based review, while an API connects markup features to another app. Check the platform labels before deciding.

Which types of files or pages must it annotate?

Pick a tool that supports the material you review: webpage annotation, PDF annotation or image annotation.

Compare these three fields directly because support differs by product.

Which review controls do you need?

If work needs formal sign-off, look for approval workflow and guest reviewers. Version history helps you see earlier changes.

Project limits can affect how you organize ongoing reviews, so check that field alongside the workflow features.

How should you compare plans and trials?

Start with the free-plan mark, then compare the listed paid starting price and whether a free trial is offered.

Prices use different units, such as per user per month or a monthly starting fee. Read the pricing note to understand the stated basis.

Do you need an API or open-source code?

A public API matters when another system must send or receive markup information. An open-source mark indicates code is available under an open-source model.

Check these marks against your integration and code-access needs before choosing.

Questions

What is markup software used for?

It adds comments or markups to webpages, PDFs and images for review work.

Which markup tools have a free plan?

Use the Free plan comparison field and the free-tier mark to find tools with no-cost access.

Can markup software annotate PDFs and images?

The board compares PDF annotation and image annotation separately, so check both fields for the formats you need.

Do markup tools offer approval workflows?

Approval workflow is a comparison field; use it to find tools with formal review sign-off.

Can I connect markup software through an API?

Yes, API availability is marked for products that publish a public API.
