One tool for websites and PDFs

Design decks, brand guidelines, contracts, marketing one-pagers — review them in the same place as your live sites, with the same anchored comments and team workflow. No switching tools between “the site” and “the doc.”

Decks & guidelines

Proof design decks and brand books page by page, in context.

Sites and docs together

No switching tools between “the site” and “the doc” — one workspace.

Upload and go

Drop in a PDF and share a link; reviewers open it straight in the browser.

Anchored comments

Pins lock to the exact spot on the exact page, every revision.

Made for review cycles

Threaded comments and replies, priority and due dates, assign and resolve, plus cross-project reports so approvals never stall.

Threaded comments

Replies stay with the pin, so context never gets lost.

Priority & due dates

Assign and resolve

Give every item an owner and close it out when it's done.

Cross-project reports

See open approvals across clients so nothing stalls.
