Compare PDF for startups
Updated July 2026
Arthize lets startup founders and teams compare two PDFs in a private workspace — free, with no watermark. Comparing two PDFs highlights what changed between versions — added, removed and edited text — so you can review revisions at a glance.
Why startups compare two PDFs
A founder exports the pitch deck to PDF, merges it with financials into a data-room file, and sends a SAFE for e-signature — without paying for enterprise document software.
Built for pitch decks. Whether it's pitch decks, cap tables, contracts, Arthize's compare pdf keeps the work inside your private workspace. Fundraising materials and cap tables are highly confidential; private processing is critical.
