No AI in your writing. Not now, not ever.
Threadbound has no AI features, and nothing you plot or write is ever sent to a language model. That isn’t a setting or a phase. It’s a promise, and it holds for every future version.
What that means.
- No features that generate, rewrite, summarise or suggest your words. Every word in your book is one you put there.
- Your work is stored on your own device, not on a server, so there’s nothing for an AI service to read.
- The app refuses scripts from anywhere else. A security policy built into it blocks them, so no AI tool or tracker can be slipped in. The one exception is Google’s own sign-in, and only once you turn on Drive backup.
- Where Threadbound seems clever, it isn’t AI. Codex spotting a character’s name in a scene is plain matching on your device. Read aloud uses your device’s own voices.
- Your writing only leaves your device if you export it, or turn on Google Drive backup yourself.
Google Drive, and Google’s AI.
If you back up to Google Drive, the files sit in your own Drive, under Google’s policies, not ours. Depending on your Google account’s settings, Google’s own AI products may be able to read what’s stored there.
You can stop that from mattering. Turn on Encrypt backups in Settings, Cloud Sync, and every backup is locked with a passphrase on your device before it leaves. Google only ever holds data it can’t read, and we never see your passphrase.
How Threadbound is built.
Threadbound has been developed with the help of Claude, an AI coding assistant made by Anthropic. I direct the work, review it, test it, and ultimately decide what ships. Claude does a lot of the typing.
While there’s a certain irony in an app that is vehemently against generative AI in a creative medium, it’s a handy tool for building software, and I’ve directed it to ensure that no part of your work can ever reach a language model.
The AI tool I’ve used to build this app has never had access to anyone’s writing, and it never will.
Why.
A book should be the writer’s own. Writing software is where unfinished, private work lives, and it’s the last place your drafts should be read by a model, used to train one, or quietly rewritten by one.
Threadbound is a place to keep your words, not to generate them.
