TapTapTeach

Problem. A teacher at the front of a room needs a student picker, a group maker, or a timer in the next ten seconds, on the phone already in their hand. What exists is built for a laptop and a projector, asks for a login, carries ads, or costs $40 a year through an app store. The writing about mobile, remote, and AI in the classroom that reaches them is mostly written by people who were not in the room for the last two waves, so it repeats the same promises.

Who. K-12 classroom teachers who pay with their own card and read about AI in teaching on their phone after school. Today they use a random-picker browser tab, a paper roster, the whiteboard timer, and Classroomscreen-style sites that break at phone width. They already arrive at freebeer.ai through Backward Builder, the Practical AI for Teachers course, and the newsletter.

Must.

• Five classroom tools (student picker, group maker, timer suite, noise meter, seating chart), each one page, free, no login, usable at 390px with no horizontal scroll, state carried in the URL so a tool can be shared with the teacher next door.
• Plus, one-time: Save class persists rosters to the account, loads them into any tool on any device, and exports the seating chart and a sub-plan as PDF. Free tools never lose a feature to the paywall.
• Three dated essays, the mobile decade, the remote year, and AI now, in Wayne's voice, vendor-side, employer generic, each ending with what stuck and what it means for the next wave.
• A catalog page pointing at every existing teacher product (Backward Builder, the course, the book, the K-12 AI policy kit) with one honest line each; a small directory of tools and sources by disruption, verdict line each, limited to what the essays and tools cite.
• Own domain and own name; nothing on the site carries the Free Beer Studio name beyond the colophon.
• The idea engine posts to the site on the calendar through an edtech beat and a taptapteach channel, no second engine.
• Classroom-level and teacher-side only: no device management, device programs, procurement, or district-buyer content anywhere on the site.

Signal. 25 phone-width tool sessions from shared or posted URLs and 10 Save class sign-ups or one Plus purchase inside 14 days; 100 tool sessions a week and five Plus purchases by day 45; measurable click-through from the catalog to Backward Builder or the course.

Output. A free teacher gets five fast tools that work on their phone and a URL they can hand to a colleague. A Plus buyer gets their classes saved across devices, every tool preloaded with their rosters, and printable seating charts and sub-plans. Both get three essays that tell them what actually survived each disruption.

Investment case

• Buyer. A K-12 classroom teacher who buys with their own card, already reads about AI in the classroom, and today uses a random-picker tab, a paper roster, and whatever timer is on the whiteboard. Never a district, ESC, or procurement contact.
• Price. $12 one-time — Teachers spend $3–15 of their own money without a reimbursement form, and a one-time price beats a subscription for a tool they use daily but would resent paying monthly for. $12 sits under Backward Builder's $15 month so the door never undercuts the product behind it.
• Path to market (owned channels). The free tools go out first and alone: each one is a shareable URL pitched to the Practical AI for Teachers course members at freebeer.ai/learn, to Backward Builder's trial users on their product page, and in the Free Beer newsletter, with the X edtech beat posting one tool a day for a week. The first buyer is a teacher who opened the picker from a shared link, built a roster on their phone, and taps Save class, which is the Plus gate. That gate ships as a sign-up wall before checkout exists, so the sign-up list is the first signal and the first buyer list. Channel: freebeer.ai/learn course members, Backward Builder page, Free Beer newsletter, X edtech beat.
• Runs to MVP. 7 runner runs for the four-step MVP chain.
• Wayne-minutes. 90 to a listed product.
• Overlap with what we sell. extends: It extends the teacher line Free Beer already sells (Backward Builder, the Practical AI for Teachers course and book, the K-12 AI policy kit) by becoming their shared front door, selling Plus to the same teachers and routing them onward.
