HOW IT WORKS

From just links to verified skills.

You choose what to learn from. 2learnit adds the structure, the assessment and the evidence — without inventing a single fact.

Bring what you already use

Paste one link or fifty — spaces or new lines, it doesn’t matter. Playlists expand into individual videos you can remove before confirming. Upload PDFs and text documents by dragging them in. Most people are set up in under a minute.

Each source shows its title, type and length so you know we found the right thing
Failures come with a reason in plain English: unreachable, paywalled, private, no transcript, scanned document, or too short
Close the tab while it processes — we’ll let you know when your pathway is ready
No account needed: your sources are kept on this device for 7 days

Get a pathway built from your sources

Your material is organised by topic — not by source — into modules with learning objectives written as things you can demonstrate. Every objective shows the sources that support it, down to the page or timestamp.

Rename, reorder, merge, split or remove anything — evidence stays attached
Thin coverage is flagged “Not covered yet”, and no checks are created for it
Where sources disagree, both are shown with their evidence
“How was this built?” shows exactly how your pathway was made

Practise in short, focused sessions

One question at a time, sized to the gap you have. Questions, answers and distractors come only from the cited source text — anything that can’t be matched to its source is thrown away before you see it.

Multiple choice, short answer and explain-in-your-words
Applied tasks with a brief, sources and clear completion criteria

EXPLAIN IN YOUR WORDS · 4 OF 8

Why might a LEFT JOIN return NULL values?

Because rows on the left with no partner on the right still appear, and the right-hand columns have nothing to show.

Track mastery, not minutes

Four transparent indicators, per module and overall. Tap any of them to see what it measures, what feeds it, and what would raise it. Spaced revision brings topics back at the right moment — in 2, 5 or 10 minute sessions.

“Not enough data yet” instead of a made-up number
One suggested next step, always with the reason
Missed a week? Your queue re-prioritises. No streaks, no guilt.

Share receipts, not claims

Your portfolio is built from completed checks and tasks. Each receipt holds the question, your answer, the result, the evidence and a timestamp — and can’t be altered once issued.

What the system does — and what it never does.

It does

Organise your sources into modules and objectives
Generate checks from the text you provided
Evaluate your answers against the cited passage

It never

Introduces facts that aren’t in your sources
Shows you an item it can’t cite
Guesses a mark when it isn’t sure — you’re offered a self-review instead
