MaximeRivest/riddle — The diary of Tom Riddle for the reMarkable Paper Pro — write with your pen, the page drinks your ink and answers in a fl

Who would use it, and what do they get?

Somebody who journals on paper; the deliverable is a written reply on the page. Real, but the platform is tiny.

What is missing today?

Handwriting on e-ink that answers back is a real and charming capability, but it is locked to one small piece of hardware. The gap is that nobody has built the same loop on the paper notebooks and tablets ordinary people already own.

What could kill it?

A reMarkable-only add-on lives entirely at the mercy of one vendor's platform, and the audience is a rounding error. Delightful demo, unclear business.

Who pays, and for what?

Niche prosumer add-on for reMarkable owners; hard to charge much, but a charming wedge into AI-augmented paper.

What is the main risk?

Tiny hardware niche (reMarkable), dependent on their platform; a whimsical demo more than a scalable business.

How much work is it?

about two weeks of work
