Learn About PDFVault
We're Derivative. We build apps a lot like ones you've already used. We think that's a good thing — the ideas are proven, so we skip the reinvention and ship the version that just works.
But Smart. We make them cost less. Where others reach for frontier models to do simple tasks, we run small LLMs locally, right on your device. No servers means no server bills — and nothing to bill you for every month.
We hate all the same things you do: subscriptions, ads, surveillance, tracking, and accounts you never asked for.
So call us Derivative. Or Derivative B.S. We take it as a compliment.
Everything our applications do — from OCR text extraction to local AI model inference — runs on your device's hardware. They work in airplane mode, without requiring any network requests.
We do not collect analytics, crash reports, or telemetry data from our applications. If you experience an issue, you choose when and what to export to us to protect your privacy.
Because our applications operate completely client-side on your device, we have no ongoing server operating costs (OpEx). We pass those savings to you with honest, one-time lifetime unlocks.
