Build Your Punch List Straight on Your Drawings
Kanna lets you build a punch list directly on your drawings, pinning instructions and defects to exact points on your site plans. Instead of red-pen markups on paper or scattered photos in chat, your team pins each item where it happens, records what needs doing and tracks it through to completion. Everyone works from the same drawing, on any device, in real time.

Pin Punch List Items to Any Site Plan
Drop a pin anywhere on a PDF drawing, add the instruction or defect, and Kanna creates a linked punch list item automatically. No more red pens, no more guessing which area a comment refers to. Just clear, trackable markups on your site plans that everyone on site can follow.

Which file types can I pin tasks to?
You can pin tasks to drawings that are PDF files, opened in the Kanna viewer on both the app and the web. Pinning is not currently available on Excel files or photos, so we recommend uploading your plans as PDFs to get the most from the feature.
How many drawing pins can I add to one drawing?
You can pin up to 300 tasks to a single drawing. That is designed to cover even large-scale sites where one plan carries many instructions and corrective items at once.
What happens to my pinned tasks when I update a drawing to a new version?
Your pins are kept when you replace a drawing with a new version, and the linked tasks always remain. Please note that pin positions do not shift, so take extra care where pages are added or removed, as a pin may no longer sit against the right area.
