An empty lecture theatre, curved tiers of seating rising away from the front of the room.

Lectures · classrooms · assignments

A lecture theatre is a conference hall that comes back every week.

The engine that holds a keynote holds a first-year lecture without noticing. What education adds is the part after the room empties: assignments with a window, courses with a certificate, and a report that says what the class believes rather than who was wrong.

Three ways to set the same thing

Live, self-paced, or a course with a certificate.

One quiz, three deliveries. Nothing has to be rebuilt to move between them, and the differences between them are deliberate rather than incidental.

A ring of clock-like tick marks dissolving into dust, while at its centre a single gold mark stays struck and sharp.

Assignments score on correctness, not speed

A live game scores on think time because the room shares a clock. Attempts hours apart share nothing, and a learner can put the kettle on mid-question, so timing them would produce a number that looks like the live score and measures something else.

A heavy switch thrown open with light released through it, and beyond it a flat gold horizon with no wall or marker anywhere along it.

Retries are a switch, deadlines are not capped

Let a learner have another go, or do not. Set a window as far out as the course needs. Neither is a decision the tool makes for you.

One bright gold point sending a single wave out across a dark field of identical nodes, brightening each one the wave reaches.

A correction reaches everybody

Editing a quiz updates an assignment already issued: the question is read at answer time, so a fixed typo reaches everyone who has not yet answered it.

Dark segments arranged as ascending steps, the lower ones lit and open, with a single blank gold disc at the top.

Courses, narrower on purpose

An ordered list of assignments with sequential unlocking and one certificate across all of it. Documents and videos would mean a second content system for material a link in a slide already carries.

Rings of light expanding outward from a small gold core, each one twice as far out as the last, and one of them returning inward.

Missed questions come back on a schedule

A question got wrong on an assignment lands in that learner's practice deck. It is asked again a day later, then two days, then four, eight, sixteen and thirty-two: one step further out each time they answer it correctly, and straight back to a day whenever they do not. Leitner boxes, not a difficulty score we would have had to invent.

How we know: Six boxes on a doubling ladder. A card reviewed today is never due again today, asserted for every box and both outcomes.

5,000in one room

Measured on one node against the real server over real sockets: 5,000 of 5,000 players joined with zero failures, every one received the question inside a 34ms window, and every answer was counted with the exact expected split. The same room was killed outright with a SIGKILL and came back with all 5,000 players in under two seconds.

After the bell

A report that says what they believe.

Counting who was wrong is a number. Naming what they were wrong about is a lesson plan, and that needs the chosen answer recorded rather than inferred.

Four bars of light rising from the dark: three of them short and cool, one much taller and gold.

Per-option distributions

Eleven people missed question four is a number. Eleven people all picked the same wrong option is a shared misconception with a name.

Two recesses cut into a dark plate: the left one holds a crimson marker struck through, the right one is empty and unlit.

Wrong is not the same as silent

A learner who answered incorrectly and one who never answered are different rows, recorded as a fact at play time. Without that, a silent learner tops the needs-help list.

How we know: Verified end to end, from the stored column through to the table cell.

A drift of separate points of light dissolving into one smooth curve that no single point can be traced back through.

AI misconception analysis, on your key

Optional, off until you connect your own provider, and it is sent aggregates (question text, accuracy and the option distribution) rather than a class list.

An open channel with no gate anywhere along it, carrying an unbroken ribbon of light out past the edge of the frame at full width.

Full report on every plan

Including the free one, and exportable as CSV at any size. Reporting is not the thing being sold here; room capacity is.

A slow connection cannot cost a learner marks.

Scoring credits the think time measured on the learner's own device, clamped by the connection's server-measured round trip and by any outage the server itself observed. Two equally fast thinkers score the same across a 25× latency gap, over real sockets.

Six silhouettes in a row on a dark surface: triangle, diamond, circle, square, pentagon and hexagon, all the same tone and told apart by outline alone.

The room in front of you

It has to work on the day.

Unglamorous, until the moment it is the only thing that matters.

  • Host from a laptop over the local network. The phones join the laptop rather than the world, which is the answer for a school with filtered wifi or a trip with none.
  • Every answer tile has its own silhouette, so a learner with a colour vision deficiency and a room whose projector has flattened the palette both still work, and everybody can say 'the triangle' out loud.
  • The tile palette is checked for separation under simulated protanopia, deuteranopia and tritanopia, and the check fails the build.
  • axe-core runs over every signed-out page in both light and dark on every build, at zero violations. WCAG 2.2 AA is the target we test against; no conformance level is claimed.

Stated plainly

What is not built.

On the same page as everything that is, because a gap somebody finds after the demo costs more than the gap itself.

  • LMS integration and rosteringNo LTI, no grade passback, no roster sync. It is real, expensive, and worth building for a named institution that needs it rather than speculatively.
  • Spaced repetition from live gamesThe practice deck is fed by self-paced work only. A live player is identified by a nickname typed on the day, and keying weeks of somebody's revision to that would hand one learner another's deck.
  • A public content libraryDeliberately absent. Built for a single workspace it is an empty shelf, and an empty shelf is worse than no shelf.

Free plan, real room

Fifty people, no time limit, commercial use allowed.

The free plan is not a demo: it runs a real room of fifty with no cap on session length and no restriction on using it commercially. Larger rooms are a one-time pass, priced per event.
