Your readers remember everything. Now you can too.
Track every character, timeline, and world rule across your books. PlotLens reads what you've written and flags the moment something doesn't line up.
You know this feeling.
The longer your series gets, the harder it is to hold it all in your head.
Was it green or hazel?
You wrote it in Book 2. Or was it Book 3? You're pretty sure it was the left cheek. Your readers are absolutely sure it was the right.
The spreadsheet taped to your monitor.
Eye colors, birthdays, who knows which secret, which magic can do what. You update it when you remember. You don't always remember.
The review that starts with "In Book 3, you said..."
Your most dedicated readers know your world better than you do. One continuity slip and the 1-star review is inevitable. It shouldn't be this way.

Review what PlotLens found.
PlotLens shows you exactly what contradicts what, with links back to the original passages in your earlier books. You decide what to fix and what to keep.
"Elena brushed her black hair behind her ear..."
Flag: continuity conflict — Book 1, Ch 4 states "Silver hair"Every fact links back to the exact sentence.
When PlotLens says your character's eyes are green, it shows you the line in Chapter 4 of Book 1 where you wrote it. When it flags a possible conflict, it shows you both passages side by side. You always know where the information came from.
"The ancient crest of House Valerius was an emerald serpent, coiling around a fractured sun."

How novelists use PlotLens
A novel gets long enough that you stop being able to hold it. PlotLens builds your Story Bible out of the draft you already have, then checks new pages against it — while you are writing, at the end of a draft, or on one pasted paragraph you are unsure about. Your Story Bible is the set of facts your story has established — what readers call canon.
Upload the draft as it stands
PlotLens reads .txt, .md, .docx, .pdf, .rtf, .odt, .epub and .fountain. File size caps by plan: 50 MB on Free, 100 MB on Plus, 200 MB on Pro and the team plans. Legacy .doc is not supported, and a scanned PDF needs OCR first.
Let extraction build the bible you never wrote
Extraction returns characters, locations, events, items, organizations and concepts, each with source attestations and a confidence score from 0.0 to 1.0. Duplicates merge automatically above 0.9 confidence; below that they go to a review queue, and the merge is reversible. Entities under 0.5 confidence are flagged for verification rather than trusted.
Confirm the rules that will police the rest of the book
Auto-derived rules arrive pending, each with the snippet of source text it came from, so you accept or reject rather than inherit. You can also write rules by hand — name, description, type, severity, constraint — and they are active immediately. There are five types: attribute, relationship, timeline, world rule and fact.
Write with real-time validation on
Real-time validation runs against the passage you are writing, debounced under 500 ms over a WebSocket, and the editor footer reports how many rules were checked and how many issues stand. It is scoped to the passage, not the manuscript — a running check, not an end-of-draft sweep.
Sweep the whole draft when you finish it
Batch validation takes the documents you select and returns findings asynchronously over minutes rather than seconds. Each finding carries severity, conflict type, a citation and a suggested fix, and is tracked as unresolved, resolved or acknowledged so a revision pass shows what actually moved.
Find the passage you half-remember
Search runs keyword, semantic or hybrid — hybrid is the default and fuses both with reciprocal rank fusion. It covers story elements, documents and established facts, and filters by chapter range, POV character, speaker, dialogue versus narration, scene type and a story-position cutoff. Search is on every plan including Free, with no quota.
