ThinkTotem

ThinkTotem turned long reads into interactive Socratic conversations. You upload a PDF, a book, an article, and instead of a summary you get active-recall prompts, spaced repetition, and explain-it-back checks. The pitch was you could move through a 300-page book in an hour or two and actually remember it.

It came from noticing that phones have rewired how I read. Traditional book reading feels like swimming against the current. ThinkTotem met the brain where it is now, and tried to still do the deep-learning work books were built for.
