Tell Lyra a topic. She brings the slides, the teachers, the whiteboard, and the quiz. You bring the questions.
10 free credits — about two evenings of curiosity.

A lesson on Lyra is built like a class period, not a feed. Here's what shows up in the room.
Each slide is voiced by one of your agents and read at a pace you set. Pause it, rewind it, raise your hand — they'll wait.
Sunlight enters Earth's atmosphere as white — a mix of every wavelength visible to us. Shorter wavelengths (the blue end of the rainbow) scatter much more than longer ones (the red end), so when we look up, we see the blue ones coming at us from every direction.
At sunset, the light has more atmosphere to push through. The blue scatters away long before it reaches you. What's left is the warm half of the spectrum.
Diagrams, derivations, sketches — drawn in time with the lesson, not stamped on a slide. You can take over the pen at any point.
Two or three agents — a teacher, a skeptic, a peer. They disagree, push back, ask the question you were going to. You can interrupt any of them.
Five short questions, written for the lesson you just had. Graded with comments — not multiple choice.
Inside Lyra, a small graph of agents — a planner, a writer, a sketcher, a critic, a panel of teachers — works for about ninety seconds. By the end you have a lesson: twelve slides, a whiteboard, a quiz, a discussion. None of it is recorded video; every line is generated for the exact thing you asked. Nothing in the room is canned.
You can sit through it the whole way, or you can lean in. Raise your hand and the lesson stops. Ask whatever you want — the panel answers in voice, with a fresh sketch on the whiteboard if it helps. Lyra paces herself to you, not the other way around.
When the lesson ends she grades the quiz, summarizes what stuck and what didn't, and writes you a short note about what to look at next. You can save the room, export it as slides, or throw it away and start a different one. Most evenings, you'll start two or three.
Each plan is a stack of credits. One lesson is one credit — heavier media (image, video, premium teachers) costs a little more.
