Writing

A real word processor

Headings, fonts, sizes, bold, italics, colours, lists, quotes, alignment and images, on an A4 page.

Spell checking

Misspelt words are underlined; right-click to correct them. The correction is recorded as such, not as pasted text.

Pasting blocked

Ctrl+V, Shift+Insert, the context menu and dragging text or files onto the page are all blocked. Copying and cutting do work.

Keyboard only

Voice dictation, the emoji panel and the clipboard history write without keystrokes, so Closed Lite rejects them. Any keyboard works, including Chinese or Japanese input.

Work over several days

Save, close and open the document again whenever you like. Each time is a new session in the record.

Images inside

Images are stored inside the .closed file and covered by the signature. Very large photos are reduced when inserted.

Record and verification

Every change, with its time

What is typed, deleted and formatted, from the empty page, and the real writing time: pauses longer than a minute and time outside the program do not count.

Exits from the program

Every switch to another window is recorded, with the time spent away.

Verification panel

Signature status in colour, author, school, dates, words, sessions, deleted characters, blocked attempts and typing rhythm.

Replay

The writing played back like a video, from ×1 to ×100, with a timeline and the flagged moments: sessions, attempts to paste or dictate, exits.

Export and report

Copies in Word (.docx) or plain text, which carry no signature, and the verification report in PDF.

Tampering detected

If the .closed file is changed outside Closed Lite, it is detected on opening and the document opens read-only, showing what does not match.

Security and files

Basic level

Closed Lite signs the document when it is saved. No certificate needed.

Medium level

Each save is also signed with the author's digital certificate: national ID card, a certificate from your school or any X.509 certificate installed on the computer.

Advanced level

Always the same certificate from the moment the document is created: only its holder can go on writing it.

A .closed file or a PDF

Text, writing record, images and signatures in one .closed file, or in a PDF that opens in any viewer and carries it inside, for platforms that only accept PDF.

Mark the PDF

The teacher marks the hand-in PDF with highlights, notes and the grade. The student sees them in any viewer and the work can still be verified.

Eleven languages

English, Spanish, German, French, Italian, Portuguese, Dutch, Polish, Catalan, Galician and Basque, changed instantly in Settings.

Write a few lines, save them and open the verification panel and the replay.
