Built-in Desktop Toolkit

Designed for Power Users

Infinity is more than a web view. It combines local productivity tools, media downloading, and privacy controls into one native app.

Download Manager

Live speed and progress tracking, ask-or-autosave modes, redownload history, and one-click file/folder opening.

Local-First Privacy

Zero telemetry, no external accounts, local JSON persistence, ad blocking, Do Not Track headers, pop-up blocking, and HTTPS-Only mode.

Encrypted Password Vault

Credentials stay safely on your machine with local encryption, nonces, HMAC integrity checks, and owner-only file permissions.

QR Code Generator

Instantly generate QR codes for any webpage URL, text, or links directly inside the address bar workflow.

Notes & Bookmarks

Tabbed browsing, instant search, local quick notes editor, PDF viewer export, and custom script injection.

Media Integration

Save YouTube Media Cleanly

The downloader is built directly into the desktop client and connects into your native download manager.

Infinity automatically detects YouTube watch, Shorts, and youtu.be links. Fetch metadata, inspect title & channel details, then download via yt-dlp straight to your output folder.
