About

PlotLock

Features
Read full description

PlotLock is a reading companion for book clubs and reading partners. Add any book, track your progress by page or chapter, and leave margin notes as you read — shared with your group in real time. READ AT YOUR OWN PACE Join a group with a simple code. You see everyone's progress, but notes written past where you are stay locked until you get there. Nobody has to read on a schedule, and nobody gets spoiled. MARGIN NOTES, NOT A CHAT Every note is pinned to a place in the book. Reach that page and it unlocks. It reads like borrowing a copy covered in a friend's handwriting, rather than scrolling a feed. AN ASSISTANT THAT WON'T SPOIL IT Ask about what you've read so far — a character you've lost track of, a thread you want to untangle. The assistant knows exactly how far along you are and will not discuss a single page beyond it. QUIET BY DESIGN No public profiles, no followers, no algorithm, no ads. Just you and the people you're reading with. FEATURES · Track progress by page or chapter · Margin notes that sync live with your group · Spoiler lock on every note and every AI answer · Share a journey with a link · Emoji reactions and threaded replies · Dark mode PlotLock was previously published as SamePage. Same app, same account, same books.
