Inkwell is a desktop writing app built for long-form authors. It keeps your manuscripts encrypted on your own device, while an AI assistant helps with style and plot suggestions, typo detection, and more. Your manuscripts are never collected by the developer — they stay safely on your machine.
Manuscripts are stored in an on-device encrypted database (SQLCipher). No forced cloud upload — write and store even offline.
Style and plot suggestions, typo checks. Billed to your own account.
Role folders, character documents, and other tools designed for long-form writing. Manage characters, worldbuilding, and plot in one place.
Manuscripts are saved to an on-device encrypted database. You can write and store offline.
Sign in with Google or use your own API key to connect a provider. Credentials stay on your device only.
Only the text you choose is sent to your selected provider, and only when you actively run an AI feature.
You choose which provider to use. No data is sent to any provider you don't use.
When you run an AI feature, the text you choose is sent to that provider's servers. How the transmitted data is processed and retained is governed by each provider's API terms.
The database is encrypted with SQLCipher, and the key is protected by OS secure storage (DPAPI).
The developer runs no server that can access manuscripts or account data. AI transmission happens directly from your device.
When you use an AI feature, the text you choose is sent to that provider's servers; processing and retention are governed by each provider's API terms.
Inkwell calls the Gemini API on your behalf through Google account sign-in. The scopes requested and how data is handled are described in detail in the Privacy Policy.
When you run an AI feature, the text you choose is sent to that provider's servers (Google Gemini, OpenAI, or Anthropic). Processing, retention, and whether it is used for training are governed by each provider's API terms. See the Privacy Policy for details.
AI usage is billed to your own AI provider account. Inkwell does not charge for or broker these costs.
All manuscripts are stored only in an encrypted database on your device. They are not uploaded to or collected by the developer.
Google Gemini, OpenAI, and Anthropic (Claude) are supported. You choose which provider to use.
It will be available for purchase soon. We'll announce it here once it's ready.
