Start from the drawings you have
Upload the PDF you already hold. Annotra adds reference numbers and leader lines to it rather than redrawing it.
Bring in whoever you need
Invite an illustrator, an attorney or a colleague onto a project. They work on the same figures without a subscription of their own.
An annotated PDF for review
Export clean, professionally annotated drawings as a high-resolution PDF, ready to go into the application.

The founder story
Built around the work of a patent illustrator.
Annotra was built by Michael Williams, a patent illustrator and the founder of American Patent Drawings (APD), his patent illustration company. Michael designed Annotra from hands-on patent drawing work to bring reference numbers, leader lines, figure labels and PDF export into one focused workflow, built by someone who understands the work firsthand.
