ChronoTwain turns one PC into the scanning hub of the office. Documents arrive in its Input Tray from anyone you invite — phones with ChronoLite Mobile, other PCs with ChronoLite (free) — and from its own scanners, screen snips and files. You fix them in seconds and each inbox delivers them where they belong: any application that scans, a printer, a folder, a compact PDF, ChronoScan or Claude Code.
One small program in the tray of one PC, between everyone who has paper and everything that needs it. Invite senders with a QR code or a link; tell each inbox where its documents go.
Anyone you invite sends them: a phone photographs them from the office or the road, a PC with ChronoLite scans a whole stack and splits it. Or snip them from the screen, drop files, scan them yourself.
Everything waits in the Input Tray: straighten, crop, fix the perspective, split a page of receipts, split or merge documents. Nothing is sent until you say so.
Any application that scans, through TWAIN or WIA, picks the scanner called ChronoTwain. Or tell the inbox what to do the moment a document arrives: print it, file it in a folder as a PDF, create a ChronoScan batch, read its barcodes. Or let Claude Code read it.
Share an inbox’s QR code or link and everyone who has it can send documents to your PC — from a phone with ChronoLite Mobile or from a PC with ChronoLite: clients, staff, residents, suppliers. No seats, no per-device fees, no accounts: one host takes documents from hundreds of people, and senders never pay.
On an invoice footer, a reception desk, a delivery van, a notice board in a building. Whoever scans it joins that inbox in seconds and can send from then on — photos, multi-page documents, even the GPS position if you ask for it.
Send a photo to the administrator.
Give every client the QR of your invoices inbox. They photograph receipts and invoices the day they get them, and you find them in the tray, ready for your accounting software — no more shoeboxes at the end of the quarter.
A QR on the notice board: “Send a photo of any damage to the administrator”. Residents report a leak or a broken light in seconds, with the location if you want it.
A QR at the dock: drivers send the signed delivery notes to the warehouse supervisor before they drive off — no paper left on the counter, nothing lost in the cab.
A QR on the counter: visitors and clients hand in their documents from their own phone, without queueing and without anyone touching the paper.
A QR on the notice board or the street furniture: citizens report a pothole, a broken streetlight or graffiti with a photo and its exact location.
Work orders, inspection sheets and signed reports arrive from the site the moment they are signed, not days later.
Customers send the photos and papers of a claim or a repair straight from the place it happened, into the inbox that handles it.
New hires send signed contracts and certificates before their first day, sealed end to end, without e-mail attachments going around.
Warranty cards, returns and receipts sent by customers from home: one QR on the ticket, and the paperwork comes to you.
Senders use the free ChronoLite Mobile (Android today, iPhone coming soon) or ChronoLite for Windows. The host’s package counts what arrives, never how many people send it.
ChronoLite is the free sender for PCs: the counterpart of ChronoLite Mobile for an office with a scanner. Your clients install it, open the invite link you sent them, and the stack they scan lands in your inbox as separate documents, encrypted end to end. Made for accountancy firms: a month of invoices goes through the feeder in one go and arrives sorted.
Download ChronoTwain + ChronoLite (free) The ChronoTwain setup installs both.
Make an inbox a barcode inbox and ChronoTwain reads the barcodes and QR codes in whatever arrives — right on your PC. The code is typed straight into the field you are working in, followed by Enter or Tab if you like, or copied to the clipboard with a notification.
The difference between taking a picture and getting a clean document into your software.
Field staff, drivers or clients send documents from wherever they are. No VPN, no open ports, nothing to configure on the office network.
Each inbox has its own key, kept on your PC. Phones seal every page before upload; the server only ever holds data it cannot read, and deletes it once your PC has it.
Everything waits in one tray. Reorder or remove pages, rotate, straighten, crop, fix perspective, split receipts, split or merge documents — or clean a page into crisp black & white with ChronoMRC’s AI.
The TWAIN scanners already on the PC work from the same window — 64-bit and 32-bit drivers alike, so older scanners are not left out.
Snip any part of the screen, or drop images and PDFs on the window: they join the tray like any scanned document.
Ask Claude to scan something: the scan window opens, you pick phones or a scanner, and Claude reads the pages. One command, /chronotwain:scan.
Make an inbox a barcode inbox: the codes in every photo that arrives are typed into the field you are working in — with Enter or Tab after each, if you like — or copied to the clipboard with a notification.
Save any document as a PDF: as scanned, compact (eight times smaller, same look) or clean black & white, with the quality you choose.
Each inbox does what you tell it the moment a document arrives: print it on the printer you choose, save it to a folder as a PDF or images, create a ChronoScan batch. A loading dock prints its delivery notes by itself.
An inbox can feed a ChronoScan job directly: a new batch for every document, or one batch for all, recognised on arrival and opened in ChronoScan if you like.
Create as many inboxes as you need and decide what each one accepts. Phones join by scanning the QR code or opening the invite link — no accounts to create, no passwords to share.
Drag the four corners onto the edges of the paper and ChronoTwain flattens it into a clean rectangle — the same geometry as our OCR products. Straighten along a line, crop, rotate, brightness and contrast are one click away, with undo.
Lay a handful of receipts on the table and take one picture. ChronoTwain finds each one and frames it; adjust a frame if you like, and every receipt becomes its own page.
Select the page where the second document starts and press Split here. Two documents sent separately that belong together? Drag one onto the other. Every phone still hears what happened to what it sent.
No scanning application? Save any document of the tray as a PDF. Our neural compression, ChronoMRC, separates the text from the background and keeps each where it belongs.
The photos exactly as they arrived, untouched.
Sharp text, faithful colours, eight times smaller. Ideal for e-mail and archives.
Shadows and paper tone gone, crisp black ink on white. Perfect for records.
Choose the folder, the name and the kind of PDF. ChronoTwain does the rest in the background and shows you the file when it is ready.
ChronoTwain includes a Claude Code plugin. Claude opens the scan window, you pick the phones or a scanner, scan as many pages as you like and send them back. Claude reads them, files them, makes the PDF — whatever you asked for.
The same window works for any application that asks ChronoTwain to scan.
Not tied to the office Wi-Fi. Phones send over the Internet; the PC only needs to be on.
Many senders, many inboxes. Invite people with a QR code; close an inbox or renew its invite with one click.
Private by design. End-to-end encryption; pages are deleted from the server as soon as your PC has them.
Real editing before it goes anywhere. Perspective, split, merge, clean up — in the tray.
Phones and scanners in one place. One window for both, 64 and 32-bit drivers.
Made by ChronoScan. From the makers of ChronoScan document capture, OCR and compression.
Anyone can send documents to your inboxes for free — with ChronoLite Mobile on a phone or ChronoLite on a PC, with no accounts, no seats and no limit on senders. You, the host, choose how many documents a month your inboxes receive. What you scan on your own PC is always unlimited.
Only what arrives counts. Each document received in your inboxes counts once, whatever its pages and whoever sends it; senders never pay and need no account. Already a ChronoScan customer? Host 1,000 is included with your license while its maintenance is active — register ChronoTwain with your license number.
Install ChronoTwain on the PC, create an inbox, and scan its QR code with ChronoLite Mobile.

For senders, free: scan a whole stack, split it into documents and send them to an inbox you were invited to — your accountant’s, your company’s. The ChronoTwain setup installs both: they always go together.
Download ChronoLiteThe iPhone app is on its way. Leave us a line and we will let you know when it is in the App Store.
Tell me when it is readyFrom the TWAIN scanners of the PC (64 and 32-bit drivers), from phones with ChronoLite Mobile (anywhere with a connection), from screen snips, and from image and PDF files. Documents from phones, snips and files wait in the Input Tray, where you can fix them before they go on.
As many as you like. Anyone who scans an inbox’s QR code or opens its invite link can send to it — there are no seats, device licences or sender accounts. Only the documents that arrive count, against the host’s package. You can close an inbox or renew its QR whenever you want to stop old invites.
The document waits, sealed, on our relay server until ChronoTwain on your PC collects it: up to 3 days for a free host and 15 days on the Host packages. Documents nobody collects in time are deleted, and the sender’s phone says so, so they can send them again.
No. Phones send over the Internet to our relay server, and ChronoTwain on the PC collects the documents from there. The PC needs an Internet connection and ChronoTwain running (it starts with Windows, in the tray).
Any Windows application that scans through TWAIN — accounting and ERP software, document management, Adobe Acrobat, IrfanView, NAPS2, ChronoScan and many more — sees a scanner called “ChronoTwain”. Both 64-bit and 32-bit applications are supported. Applications that scan only through Windows (WIA) — Paint, Windows Fax and Scan, Word — see it too and open its window to choose the pages. Applications that do not scan can get the documents as PDF files.
No. Each inbox has its own encryption key, created and kept on your PC. The phone encrypts every page and its details before sending; our server only stores the sealed data and deletes the pages as soon as your PC has downloaded them.
Yes, if it has a TWAIN driver for Windows. ChronoTwain lists the scanners of the PC next to the phones, including older 32-bit-only drivers.
Senders get a clear message and can send again when the month starts over, or straight away once the host moves to a bigger package. Scanners, files and screen snips on the host’s PC are never limited.
The host — the PC that receives them. Senders never pay: ChronoLite Mobile and ChronoLite for PCs are free, need no account, and send to any inbox they are invited to.
Yes. Open the inbox, Edit inbox, and under Also add a destination: print on a printer of the PC, save to a folder (PDF, compact PDF or images), send to ChronoScan. Every document that arrives goes there the moment it lands, and leaves the tray unless you ask to keep it. More destinations are on the way.
The free sending app for PCs: whoever has your invite link scans a whole stack of paper (or adds PDFs and photos), splits it into documents with the scissors between pages, and sends them to your inbox, encrypted end to end. It comes in the ChronoTwain setup: the two are always installed together.
Yes. ChronoLite Mobile also sends to the mobile inbox of a ChronoScan job, which processes the pages and posts a result link. Install the ChronoScan Mobile Inbox station on the ChronoScan PC and create the inbox from the job.
Not yet — it is in development. Android is available today.
Scanners, screen snips, files and any number of phones — into any application. Free to use.
