I tried a lot of apps. Always too simple, too bloated, or everything scattered, nothing connected. So I built what I was looking for.

Too simple
Great for notes, limited for a full novel.

Studio
Everything you need. Nothing you don't.
Too complex
Powerful, but the interface buries what matters.

Frequently asked questions
-
ThirdHand Studio is a desktop novel editor built for writers with atypical brains (ADHD/ASD). All-in-one: writing, character sheets, relationship graph, built-in Pomodoro and daily heatmap. Your files stay on your machine, no account required.
-
Yes, the launch will be on the Mac App Store. A Windows version is planned for later.
-
One price. One time. Forever. ThirdHand Studio is a one-time purchase: pay once, use it for life. No subscription, ever. The exact price will be announced at launch.
-
Yes. Your stories belong to you. Export to standard formats is planned for launch.
-
It's not planned for launch. This is intentional: your data stays local by default. If a cloud option is ever added, it will be optional and won't change the base price.
-
No. And it's impossible by design: your data never leaves your machine. There's no server, no connection, no model watching your text. What you write is yours, entirely.
-
Generative AI has no place in your writing. No suggestions, no autocomplete, no text generated in your name: your creative voice is at the heart of the app. In the future, utility tools (chapter summaries, semantic search) may be considered, but only through local models running on your machine. Nothing will ever leave the app.
