Sheaf — Document Review
Annotate PDFs and contracts
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Review Word and PDF documents on your phone without fighting a desktop UI. Sheaf keeps your documents and notes on-device until you decide to share them.
Sheaf is a mobile-first app designed for reviewing business documents — contracts, NDAs, term sheets, policies — without uploading them to a third-party service. Open a Word or PDF on your iPhone or iPad, flag the clauses that matter with a long-press, and keep your work on your device wherever you happen to be reviewing it. A 7-day free trial lets you test the full app before committing to a subscription.
MOBILE-FIRST, NOT MOBILE-PORTED
Sheaf is designed around how a phone actually gets used — short windows, scrolling with a thumb, and very little typing. The capture flow is deliberately minimal: one field for your flag note, and you're done. Add a voice memo, a photo, or more detail later if you want.
• Long-press a clause to capture a flag. For Word documents, the selection snaps to the whole paragraph automatically — no precision dragging on a phone.
• Four flag kinds — Issue, Risk, Question, Note — to triage clauses at a glance.
• Voice memos and photos can attach to any flag — useful when typing on a phone is the wrong tool.
• Group documents by Matter to keep clients and projects separated.
• Cross-document search across every file in your library.
• Annotated PDF export for hand-off. Portable JSON flag export for sharing your review with a colleague who also runs Sheaf.
YOUR DATA STAYS YOURS UNTIL YOU SHARE IT
Sheaf does not have a server. There is no Sheaf account to sign up for, no Sheaf cloud to upload to, no analytics pipeline, and no third-party SDKs phoning home. Your documents, your flags, your voice memos, and your photos live only on your device.
• The local database and document store are protected with iOS data-protection class Complete — encrypted at rest, inaccessible while the device is locked.
• Face ID / Touch ID app lock is built in.
• The original Word or PDF file is never modified. Annotations live in a separate on-device store; the file you imported is byte-identical to the file you can hand back.
• The only way your work leaves the iPhone is when YOU tap Share, AirDrop, or Mail. You stay in control of every byte.
• No advertising, no ad SDKs, no data-broker pipelines. Sheaf is paid for by its subscribers, not by selling your reading.
FOR
Attorneys reviewing privileged contracts on the train. In-house counsel who need to skim an NDA between meetings. Founders reviewing term sheets they'd rather not paste into a chat tool. Procurement, HR, compliance, and finance professionals who handle documents that shouldn't leave the device.
If you need a multi-user comment thread synced through a vendor, Sheaf isn't that. If you need to review a business document on a phone without trusting a cloud, Sheaf is exactly that.
