A local-first manuscript studio · Alpha 2026
From sprawl to story.
A minimal, distraction-free writing surface that stays out of your way, but with every tool a novelist needs in easy reach. Per-chapter drafts without chaos. Automatic click-to-restore snapshots of every draft. Offline by design: no account, no subscription to write. Effortless character and entity tracking — rename once and all instances update. Series, book, chapter, and scene level click-and-drag organization with notes. Separate in-the-margin commenting system. Typewriter mode with sentence focus. No visual clutter.
Be you plotter, pantser, or gardener, Mnemosyne helps you be a writer.
Alpha invitations go out in small waves. We’ll email once to confirm, and never sell your address.
Then, cresting a rolling hill, they saw it. The road ahead simply ended. It was not a hill or a valley that blocked their path, but a wound. A line, sharp as an amputation, divided the familiar black soil of the grasslands from an alien landscape of jagged, red-granite hills that clawed at the sky. Hills that had no business being in the Garrondell Grasslands.
Taming the storytelling sprawl
An idea became notes. Notes became a collection of Word docs. Then maybe a wiki, or an Obsidian vault. Then Scrivener. Or perhaps a folder full of files with names like chapter3_final_v3_FINAL. Mnemosyne connects your worldbuilding, tames the chaos of a sprawling writing process, and lets you focus on what matters: your story.
Stories are complex. Characters, places, factions, events, lore, and the history that binds them. Multiple drafts. Notes in the margins. The ability to restore what you wrote last week, or last month. No writing tool has ever handled all of these elements of storytelling at once while keeping the writing surface clear. Mnemosyne doesn't write for you. It's process, and it's organization.
Your data remains portable, safe, and local. Data integrity is the beating heart of Mnemosyne. Automatic snapshots keep your revision history in navigable waypoints. Every keystroke is saved within seconds, and verified backups roll quietly in the background. A crash costs you a moment, not a manuscript.
Local data. Always portable.
Your manuscript lives on your computer, not on our servers. No account, no internet connection, and no subscription needed to write. Alongside your project, Mnemosyne keeps a plain-markdown copy of every chapter, note, and Codex entry, refreshed as you write, so you’re never locked into a proprietary format. Privacy and portability as architecture.
AI-free at its core.
Mnemosyne organizes, links, and preserves what you write, using plain rules on your own machine. It does not generate prose, finish your sentences, or “suggest the next 300 words,” and your words are never used to train anything. If we ever offer AI, it will be an optional add-on, off unless you choose it. The core app will always be AI-free, made for the wonderful, flawed, irreplaceable humans who write stories.
Why this exists
Like most of you, my writing isn’t paying my mortgage. By day, I’m a radiation oncologist. I deal with cancer, and all the attendant, life-altering consequences for patients and their families. But a lot of what I do is help them write their stories. Stories of resilience and courage in the face of mortality.
I’ve always been a storyteller, from my misspent childhood as the forever-DM of my friends’ D&D group to the stories I help my patients tell now. And I’ve been writing. What began as a pandemic-isolation D&D campaign grew into a story that would not leave me alone: a hundred thousand words of manuscript sitting on nearly a million words of worldbuilding.
I cycled through Word, Obsidian, Scrivener, and others. Each did one or two things well, but none did everything. I wanted to write multiple drafts, keep a full history, rename a character without chasing down every stray mention, and keep my worldbuilding wired to the manuscript. And I wanted all of it within easy reach of a plain, minimal, beautiful interface with no distractions. So I built it.
If you’ve ever felt this, Mnemosyne was built for you. Your writing software should never require you to be a database manager or an organizational guru. Every tool it offers should serve a single purpose: to help you write, then get out of your way.
Write where nothing is lost.
