XOsign vs Dropbox Sign
Dropbox Sign, formerly HelloSign, is Dropbox's e-signature product, and it makes most sense for a team whose files already live in Dropbox and who want signing to sit next to that storage. XOsign is for a small business that wants the storage itself to be intelligent rather than merely nearby. The one-sentence difference: Dropbox Sign puts a signature beside your folders, while XOsign removes the need to choose a folder at all — and then tells you where every copy of the document went.

What XOsign does that Dropbox Sign does not
An XOsign document is a smart one, not just a signable one. Every item below is built and shipped today, and each links to the place you can see it.
The folder chooses itself
Dropbox Sign sits next to folders you maintain. XOsign reads every upload as it arrives, works out what kind of document it is and puts it where that kind lives — and search reads inside it, so a contract saved as Scan_2026_004 still turns up under the client's name.

Once a file leaves a shared folder it usually stops being yours. XOtrace registers every export with its own serial and a concealed mark that survives printing, photocopying and scanning.
See XOtraceThe document explains itself
Clauses, obligations, dates, amounts and anything risky, vague or missing, in plain language, on the original — no editable copy required.
See what it readsYour contract and theirs, side by side
Compare the version you sent with the version that came back, differences called out and explained, with several vendor quotes readable in one table the same way.

Manual e-signing is on every XOsign plan, including the free one, with the full audit trail. The signer opens a link and signs — no account, no seat.

SHA-256 hash and an RFC 3161 trusted timestamp on every signed document, checkable by anyone holding the file on a public page.

Where Dropbox Sign is stronger
Dropbox Sign (formerly HelloSign) is Dropbox's e-signature product — a natural companion for teams that already keep their files in Dropbox — with a published developer API. A comparison page that only flatters its author is not worth reading, so here is the honest case for them.
- Living where your files already are. If your business runs on Dropbox, signing inside that world removes a whole category of moving files around, and that convenience is real.
- A published developer API with SDKs, embedded signing and a free test mode, which makes it a common choice for products that need to embed signature.
- A signing experience with a long reputation for being finishable by a first-time recipient without instructions.
- The weight of Dropbox behind it — storage, sharing, and the account your team already has.
- A published free tier and simple plan structure that many small teams find easy to reason about.
A document that understands itself
Most tools treat a document as a file to move from A to B. XOsign reads it the moment it arrives and everything afterwards — the filing, the search, the comparison, the field placement, the plain-language explanation — works from that one reading.
The document understands itself
One AI reads every document the moment it lands — the parties, the dates, the amounts, the clauses and what is risky, vague or missing — and everything you do with it afterwards reads what that pass wrote.
Never organize a document again
Uploads are read on the way in, told apart by class, and filed where that class lives.
Compare your contract to theirs
Put your version and the version they sent back side by side, with the differences called out and explained in plain language. Several vendor quotes can go in one table the same way.
Every copy knows where it went
XOtrace registers every export with its own serial and a concealed mark that survives printing, photocopying and scanning. Paste a serial or drop a page in and XOsign names the copy.
Seven languages on screen, more than forty on the page
The app itself is in English, Spanish, French, Haitian Creole, Brazilian Portuguese, Vietnamese and Simplified Chinese. Documents translate further, with the original preserved alongside.
A record anyone can check
Every signed document carries a SHA-256 hash and an RFC 3161 trusted timestamp, and anyone holding the file can check it on a public page without an account.
