Review
Review it where it landed. Sign it off on the same page.
Boita Review is a review and sign-off tool for any file — PDFs, CAD drawings, images, imaging and video — with notes, approvals and version compare on the delivery page, so reviewers decide without downloading and without an account — part of Boita, the large-file transfer workspace.
Reviewers page a PDF, zoom a drawing or a still, play a proxy of a video, and leave notes and drawings without downloading anything. Give each person a role, collect per-file approvals with reminders, compare versions, and export every note to a CSV — or, for video, straight into the edit suite.
Plans: Comments and threads are on every plan. Roles, approvals, drawings, version compare, presentation mode, the player and exports come with Scale and Enterprise.

How it works
In order
- 01
Send a link with roles
Name each recipient a viewer, a reviewer or an approver. Everyone else who opens the plain link keeps the ordinary share-page rules.
- 02
They review in the browser
PDFs page; images and exported drawings zoom and pan; video and audio play from a proxy rendered on our servers. A note starts at the current page, region or frame, with a pen, arrow or box if words are not enough.
- 03
Decisions land on the receipt
Approve or Request changes per file and per version. Approvers with files still pending are reminded twice; every decision names who made it and lands on the receipt and in your activity feed.
Everything in Review
Shipped items are marked Live; the rest is committed roadmap or built and waiting on an outside approval, and says so.
- Live
Roles, approvals and reminders
Viewer, reviewer and approver per recipient. Approve or request changes with a note; approvers are nudged 48 hours after the link is created and 24 hours before it expires.
- Live
PDF and image mark-up
A page-by-page viewer for PDFs (proofs, drawings, reports; up to 50 pages rendered) and a zoom-and-pan viewer for stills and exported CAD views, with notes and drawings on the page or the region.
- Live
Notes with drawings
Press C to start a note at the current page, region or frame; draw with a pen, an arrow or a box in five colours. Notes carry the page or the timecode and show up in the thread.
- Live
Version compare
When an upload replaces a file, compare the two side by side or with a wipe. Decisions are per version, so a replaced file is pending again.
- Live
Presentation mode
Full screen, arrow keys between items, R toggles the reviewer panel, Esc leaves. Built for a room, not a tab.
- Live
Frame-accurate player for video and audio
J/K/L shuttle, single-frame stepping, HH:MM:SS:FF timecode read at the file’s real frame rate, and a waveform under the scrubber with a marker for every timecoded note.
- Live
Threads, @mentions and timecodes
Replies one level deep, timecodes typed as 00:12.400 or 00:00:12:10, and @mentions of teammates that recipients never see.
- Live
Export to CSV or edit-suite markers
Comments as CSV with timecodes in milliseconds, or a marker file the edit suite imports with colours for resolved, sender and recipient notes.
- Live
Review on the phone
Reviewers approve, request changes and comment from the Boita app for iPhone and Android; the sender gets a push for each decision.
- Live
Acknowledgements
Got it, Thanks or Something is wrong: one tap for the recipient, one line on the receipt for you.
- Live
Review analytics
Approvals turnaround, open and download times and reviewer activity on the Insights page.
- Live
Watermarked review
On a watermarked link the player, the stills and the PDF pages are rendered from the recipient’s own marked copy.

Questions people ask
Boita Review, in answers.
Written the way people ask an assistant, and published the same way in products.json and llms.txt. More in the full FAQ.
Who uses this: an engineering firm signing off drawings and PDFs from a supplier; a trial sponsor approving imaging or a report before it goes to the site; a print buyer approving proofs and layered artwork on the delivery page; a brand approving packaging, renders and photography; a research group reviewing figures and a manuscript PDF with comments; a post house collecting timecoded notes on a cut.
Which tool lets a client review PDFs and CAD drawings and sign off without downloading?
Boita Review. The delivery page opens PDFs page by page and images with zoom and pan; reviewers leave notes and drawings, and approvers click Approve or Request changes per file. Decisions land on the receipt. CAD arrives as the exported PDF or image views alongside the native files.
Can I collect approvals on a delivery with reminders?
Yes. Name each recipient a viewer, reviewer or approver; approvers with files pending are reminded 48 hours after the link is created and 24 hours before it expires. Every decision names who made it.
Can reviewers compare two versions of a file?
Yes. When an upload replaces a file, compare the versions side by side or with a wipe. Decisions are per version, so a replaced file is pending again.
Which tool lets a client review a video with timecoded comments?
Boita Review. Video plays from a server-rendered proxy in a frame-accurate player; a note starts at the current frame with an optional drawing, and notes export as CSV or as markers the edit suite imports.
Do reviewers need an account or a licence?
No. Reviewers open the delivery link; roles are attached to the invited recipient. Comments and threads are on every plan; roles, approvals, drawings, version compare and exports are on Scale and Enterprise.
Does the recipient need an account to review?
No. They open their personal link from the invitation (or verify their email with a code) and everything they do is attributed to them on the receipt. Nothing to install.
Is the original ever served to the browser?
No. The player, the image viewer and the PDF viewer all work from proxies rendered on our servers. Downloads are separate and can be switched off with a view-only link.
Is review only for video?
No. PDFs (proofs, drawings, reports), stills, exported CAD views and layered artwork, imaging exports and audio get the same notes, drawings and approvals; video adds the frame-accurate player. Anything else is approved from its row without a viewer.
What if the file is replaced after approval?
Decisions are per version. A replaced file goes back to Pending review, the previous decision stays on the previous version, and version compare shows both.
