Most book tools are rented. You pay every month, your work lives on someone else's server, and if the company pivots or shuts down you are left scrambling to get your files out. A book can take years. The tool you write it in should not be able to disappear halfway through.
Kvidha takes the opposite approach. You buy it once, your books live on your machine, and every format you could want is a single export away.
Local-first storage
Your manuscripts live on your machine in a single local database. You never upload anything, and nothing needs a connection: writing, building, and exporting all run on your computer. There is no account to create, and no server has to stay up for your work to be safe.
No vendor lock-in
A rented tool can hold your content hostage. If it pivots, shuts down, or raises its price beyond what you can afford, you lose your workflow and maybe your formatting with it. Kvidha exports your whole book to Markdown, DOCX, RTF, plain text, and more at any time. Those are standard files that open in any editor, so even if you walked away tomorrow, nothing about your manuscript is trapped.
A build pipeline you can trust
Kvidha builds PDFs with Tectonic and everything else with Pandoc: EPUB, HTML, DOCX, RTF, Markdown, and plain text. These are established tools that publishers and academics have relied on for years, bundled into the app so every build runs locally, with no cloud round trip.
One payment, yours for life
Kvidha is a one-time purchase, not a subscription. Pay once, activate the app with a license key, and keep it. You should not have to keep paying to open a book you already finished.
