Pure Offline. Private by Design.
100 powerful desktop tools for productivity, development, documents, data, and more. Work locally, keep control of your files, and stay productive without the internet.
This frame will show the real application interface at full size.
Required asset: 1600×1000 captures of the running desktop app (light + dark theme), placed in apps/web/public/shot-light.png and shot-dark.png.
One toolkit for text, files, code, data, media, and math — every tool verified local.
Files are processed on your device. Tool execution sends nothing to any cloud.
No account, no activation, no telemetry. Missing resources fail openly — never silently online.
All 100 tools work without AI. Local models are strictly opt-in, on-device only.

How Jeterio works
Three steps. No account, no cloud workspace, no learning curve tax.
Download and install
Grab the installer for your OS below. Internet is needed only to download the app and any updates you choose.
Open the tool you need
Search 100 tools by name, or browse curated collections for your workflow.
Work locally, save locally
Results save to your device. History and search stay on-device too.
Privacy by design, not by promise
Architecture you can verify: disconnect the network and everything below keeps working.
Conversion, formatting, encryption, and analysis run in the app on your machine.
Operation history and saved results live in local storage. Sensitive tools record metadata only.
Compatible models you install yourself. Absent models produce a clear message — never a cloud fallback.
Find anything, revisit everything
Universal search across tools, eligible saved results, and history — plus per-tool search and a global History page, all offline.
Press Ctrl+K anywhere in the app to jump to search.
Built for the desktop
Keyboard-first workflows, real file and folder operations, batch processing, detailed outputs, and a persistent searchable workspace. Jeterio is a desktop application — there is no mobile app and no browser version of the tools.
