Track characters, catch contradictions, surface themes, and ask questions across your whole novel, all while your words stay on your own machine.
A character introduced in chapter three goes quietly missing. Two scenes disagree about what day it is. A theme you cared about fades out and never returns. Not because you're careless - because no one can keep a whole novel in working memory at once.
People who appear, matter, then vanish without resolution across hundreds of pages.
Ages, seasons, and sequence that quietly contradict each other between chapters.
Setups with no payoff, facts stated once and silently reversed later on.
Motifs you're building without a way to see whether they actually recur.
Aevum reads everything you've written and keeps track of it as you go, so the whole book stays legible even when it's far too long to reread. No tagging, no filing - it works from your prose.
Every image below is a capture of the running app on a manuscript in progress - not a rendering, not a mockup.
Aevum derives a graph from your prose as you write - characters, themes, and the relationships between them - without ever asking you to tag a thing. One source of truth; structure, timeline, and theme are just windows onto it.
how the graph works →The rain began before I noticed it had begun. There was the kettle, pretending to whistle, and there was the small room where I keep what I cannot say out loud.
I have been thinking about water again. Not the sea - I am not interested in the sea - but the way a cup holds it without complaint. The way it forgets its shape every time you ask it to. Father would have called that obedience.
An intelligence that runs on a model on your own machine - it reads, it never writes for you. It watches the prose and reflects what it notices: an echo here, a register shift there, a character becoming your most-named presence.
Commit to a stretch of deep work and the room closes around you: no clock, no notifications, no exits. A candle burns down as your minutes do - the only timekeeper you're allowed. Break the seal early and it costs you, by your own arrangement.
enter focus mode →generates text. A blank page filler that doesn't know your book.
organizes files. A binder for drafts that never reads them.
manages notes. A web of pages you have to link by hand.
understands manuscripts. It reads the whole novel and keeps track of it.
Not another AI writing app. The operating system for long-form writing - the software that actually understands your book.
Aevum is local-first by default. Your manuscript lives as plain files on your own disk - not on our servers, not behind an account, not anywhere we could read it.
Every volume is stored on your device in open formats. Back it up, sync it, move it - it is yours.
The app opens with no sign-in and phones home to no one. We collect nothing about what you write.
The local intelligence reads your prose without a single byte ever leaving your machine.
Only the optional cloud analysis uses the network - and only the passage you choose, encrypted in transit.
Write the long book.
Let the software remember it for you.
Aevum reads your whole manuscript, tracks every thread, and answers when you ask. Free to start, on your own machine.
