Help centre The sealed editor

Why can't I paste into Loam?

Why Loam blocks pasted prose, what remains available, and how to prepare a class before its first witnessed assignment.

You haven’t broken anything, and neither has your student. The Loam editor refuses pasted prose on purpose: it’s the single most important thing it does.

Why it’s blocked

Loam’s whole promise is that a finished document comes with proof of how it was written: every edit, in order, tamper-evident. That proof is only worth something if the text actually entered the document here. If a thousand words could arrive in one paste (from a chatbot, an essay mill, or a sibling’s old assignment) the replay would show nothing and the evidence would prove nothing. Blocking paste isn’t a restriction bolted onto the product; it is the product.

The same rule applies to dropping text in, and to the title field. And it applies to everyone: there’s no teacher override that quietly lets text in, because an exception anyone can grant is an exception the evidence can’t rule out.

What still works

  • Pasting a single link. A bare URL pastes fine and becomes a link in the document. Citing a source never requires retyping an address.
  • Attaching files. Images, PDFs and audio can be pasted or dropped in. They’re recorded as attachments: supporting material, never counted as typed prose.
  • Undo and redo. Normal editing history works as usual.
  • Quotes, typed. Students quote sources by typing the quotation. That’s deliberate: the replay then shows the quote being transcribed, which is exactly what honest quoting looks like.

What a blocked paste looks like

The student sees a notice, “Text paste blocked”, telling them how many characters were not inserted and what is still allowed. Nothing enters the document. The attempt itself is recorded in the evidence record as a blocked event, and teachers can see a count of blocked attempts alongside verification. Students should know that: it’s not a trap, it’s the same transparency the rest of the record gets. One blocked paste usually means someone tried to paste their own notes before learning the rule. A pattern of them the night before a deadline reads differently, and that judgement belongs to the teacher, not to us.

Tell your class before the first assessment

Most paste confusion happens mid-assessment, which is the worst possible moment for it. Thirty seconds of briefing prevents all of it. Something like: “This editor only accepts typed text. Links and file attachments work; pasting prose doesn’t, for anyone. Write in the editor from the start rather than drafting elsewhere.”

That last point matters most. A student who drafts in another app and then tries to paste the result will find they have to retype it all: technically possible, but slow, and the replay will show one long transcription rather than their actual thinking. Drafting in Loam from the first sentence is less work and better evidence.

Honest caveat: paste-blocking stops text arriving through the clipboard. It cannot stop a determined student retyping from another screen. No tool can, short of the cameras and lockdown browsers we refuse to use. What Loam gives you is the replay of how the text arrived, pauses and revisions included. Reading it is a teacher’s judgement; making a rewritten draft show up in that record is ours.
