Presenter layer immune to iPadOS display changes

Present slides and handwritten annotation to a browser-based room display while notes, polls and controls stay private on the teacher's iPad.

A ready-to-paste brief for Claude Code, Cursor or any coding agent.

I want to build a small, bootstrappable product. Help me plan and start the MVP.

Product: Presenter layer immune to iPadOS display changes
What it is: Present slides and handwritten annotation to a browser-based room display while notes, polls and controls stay private on the teacher's iPad.
Who pays: University lecturers and K-12 teachers who teach by annotating from an iPad; $8–15/mo individual plans, plus $1.5–5k/yr school site licenses from the instructional technology budget.
Closest alternatives: theopenpresenter.com (early, self-described as basic), GoodNotes/Keynote/PowerPoint native presenter modes, Explain Everything / Doceri whiteboard apps, Mentimeter / ClassPoint for polling
The gap: Native presenter modes all depend on OS-level second-screen behavior Apple just broke and has changed repeatedly; polling tools don't do live handwritten annotation over handouts; the one independent web-receiver entrant is new and rudimentary, leaving no mature, trusted option for the teach-by-annotating workflow.
Why now: iPadOS 27 shipped weeks ago and broke AirPlay presenter mode for exactly this audience, which is actively hunting for workarounds and being told not to upgrade — a rare moment of acute, publicized pain with an annual school budget cycle to catch.
Moat to build toward: Course materials, slide decks, polls and note templates accumulate inside the tool, and adoption tends to spread department- or school-wide, creating switching costs; not a deep technical moat but real workflow lock-in.
Biggest risk: Apple reverts or fixes the behavior in a 27.x point release and teachers fall back to the free, built-in presenter modes they already know.

First three steps:
1. Build a web receiver page (runs on any classroom computer/Chromecast browser) that displays the shared canvas and slides.
2. Ship an iPad app that imports PDFs/PowerPoint, streams annotation to the receiver, and keeps notes/polls on a private presenter view.
3. Add live polling with results visible only to the presenter until revealed, mirroring the workflow the article describes.

Start by asking me up to five questions about constraints (stack, budget, timeline), then propose the smallest version a paying customer would use, and scaffold it.

What people said · 4

A lecturer's whole teaching workflow (private notes, hidden poll results, annotated handouts projected via AirPlay) broke in iPadOS 27, exposing private content to students and causing embarrassment at conferences. From the article ↗
A teacher notes the majority of teachers at their school present from iPads and that presenter-mode behavior is inconsistent and unreliable across apps like Notability, PowerPoint and Slides. Read the comment ↗
A user reports AirPlay is chronically unreliable, with random disconnects mid-session and multi-year display bugs that survive macOS releases. Read the comment ↗
A commenter was motivated enough by this class of problem to build a separate control/presentation web tool connecting to PowerPoint and Slides, but says it is still basic. Read the comment ↗

Course materials, slide decks, polls and note templates accumulate inside the tool, and adoption tends to spread department- or school-wide, creating switching costs; not a deep technical moat but real workflow lock-in.

Against

Red team: Multiple independent teachers describe a workflow Apple has now broken across several releases, a browser-receiver architecture genuinely decouples from OS presenter-mode churn, and the acute post-iPadOS-27 window aligns with school budget cycles.
What would kill it: Apple reverts or fixes the behavior in a 27.x point release and teachers fall back to the free, built-in presenter modes they already know.

Start

First three steps: Build a web receiver page (runs on any classroom computer/Chromecast browser) that displays the shared canvas and slides.
Ship an iPad app that imports PDFs/PowerPoint, streams annotation to the receiver, and keeps notes/polls on a private presenter view.
