Lens · The live lecture layer

Drop in your deck.
Watch the room think.

Lens turns the slides you already have into a live, student-personalized immersive session. Upload a PDF or PowerPoint, drop sim scenes, polls, and writing prompts straight onto a slide — or ask Conjure to build any activity from the slide on the spot — and run it live, while Class Pulse shows you, in real time, exactly who's with you and who's lost.

Most of the room has the timing idea, but the "profitable yet insolvent" case is splitting them. Worth one concrete example before moving on.
See it live

Build it, then run it
on the whole room.

Games, simulations and debates the whole room plays at once - built before class in Conjure Live, or on the spot from the slide you are teaching.

Conjure Live & Lens · a full walkthrough
From slides to a live session

Five steps. No new
way to teach.

You bring the lecture you'd give anyway. Lens makes it interactive, watches the room with you, and hands back study material on the way out.

01
Upload your deck
Drag in a PDF or a PowerPoint. PDFs render pixel-perfect; PowerPoints come in with text and layout intact, ready to edit. Nothing to rebuild.
PDF · PPTX
02
Drop live activities onto any slide
Ask Conjure Live for a sim scene, a vote, a quick check, a writing prompt or a debate - built from that slide’s content, right where it belongs in the flow.
Built by Conjure Live
03
Go live — students join from any device
Present full-screen while students follow along on their phones or laptops. They react, answer overlays, raise a hand, and drop comments without breaking the room's focus.
Phone · laptop
04
Read the room with Class Pulse
A live sidebar shows got-it vs. lost per slide, reaction stream, raised hands, and comments — plus an AI understanding check that tells you in plain language what's landing and what to slow down on.
Real-time
05
End & reveal — then turn it into study material
Close the session to reveal results, and generate a study set and flashcards from the lecture in one click. Every response flows into Analytics, so you walk into next class already knowing the room. And once the deck is published, its slides are a source the Class Agents quote - a student who asks the Mentor about slide 12 at 11pm gets the slide, not a paraphrase.

The signature

Class Pulse — the room,
without the silence.

"Any questions?" gets you a quiet room and no signal. Pulse gives every student a low-friction way to tell you where they are, and reads the whole room back to you while you teach.

Got it / Lost, per slide
One tap from every student on every slide. You see comprehension move in real time and know when a slide needs another pass before it's too late.
Reaction stream
Got it, lost, idea, fire, wow, hand up, bored - one tap, no typing. A fast, ambient signal that doesn't interrupt the flow: the energy of the room, made visible.
Raised hands & comments
Students flag a question or drop a comment tied to the exact slide. Nothing gets lost, and quiet students get a voice that doesn't require speaking up.
AI understanding check
The AI reads reactions, comments, and overlay responses and tells you — in a sentence — what's landing and what to revisit. Your read on the room, summarized live.
Session controls & timer
Drive slides, launch overlays, and keep pacing from one panel. Split-view keeps the deck and the pulse side by side, or pop pulse out on a second screen.
Everything lands in Analytics
Pulse isn't just for the moment. Every reaction and response feeds the per-class record, so confusion you saw live shows up in concept-difficulty and at-risk tracking afterward.
Conjure Live

Your whole toolkit,
inside the slide.

In Lens, Conjure Live builds the activity from the slide you are teaching and pushes it to every screen in seconds. These are the ones people ask for first - describe anything else you need and it appears, live.

Meet Conjure — the live builder inside Lens
Type what you want in plain language and Conjure builds it from your slide and pushes it live — so the activities below are a starting point, not a limit.

Live sim scene
Drop a decision scene from a simulation into the lecture — personalized to each student's interests. The class votes a path, defends it, and sees the consequence play out together.
Explore Simulations
A vote on the call
Multiple choice, a ranking or an open answer, built from the slide and answered on phones - results revealed when you’re ready.
A quick check
A few questions on the concept you just taught, answered on phones, with results back before you move on.
Writing prompt
A short answer or a longer free response that gets students writing in the moment instead of just nodding along. Take it home as a peer review round in Conjure Assign.
Peer review in Conjure Assign
A debate
Give the room a hard call built from the slide, have everyone commit to a side, then let the AI press on their reasoning.
Debates in Conjure Assign
Whatever the moment needs
A ranking game, a word cloud, a market that clears, a whiteboard the room fills in - describe it and Conjure Live builds it from the slide.
Live sim · personalized

One question.
Everyone's own world.

Drop a sim scene onto a slide and the whole class works the same decision and the same lesson — each re-skinned to a world they actually care about. Flip through the room, student by student.

Same lesson, every time
The decision is identical for all 32 students — cash-flow trade-offs under a hard deadline. Only the world around it changes. Maya defends a tour budget; Diego defends a transfer window; Aisha defends a studio's runway. Same rubric, same reasoning — far more engagement.
Why Lens

Built for thinking,
not for watching.

/ 01
The room does the work
A normal lecture asks students to receive. Lens makes them decide, answer, and write every few slides — so attention isn't optional and thinking happens in the room, not just after it.
/ 02
You see comprehension live
No more guessing from a sea of nodding faces. Pulse tells you who's lost on slide 12, not on the midterm — early enough to actually do something about it.
/ 03
Nothing new to build
Lens runs on the deck you already have. Upload, add a few overlays, go live. No rebuild, no new lecture style, no learning curve for the class.
/ 04
The lecture keeps working
When you end the session, the lecture becomes a study set and flashcards, and every response feeds Analytics. One class period does triple duty.
See your next lecture,
live.

Bring a deck you already teach from. We'll show you what it looks like with Lens running — overlays, Class Pulse, and the study set that falls out the other side.
