No queue and no turnaround
Annotate a set the moment it is ready instead of sending it out and waiting on someone else's schedule for it to come back.
Unlimited projects and figures
Plans are not metered by drawing count. Annotate as many figures across as many projects as the work needs.
Revisions cost nothing
Change a callout and export again. A correction is a click here rather than a new round with an outside drafter.

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.
