# URLinks — Full Documentation for AI Systems

> The AI-native, free link management platform. Go links, short URLs, QR codes, link-in-bio pages, and analytics — all free, all API-first.

## What URLinks is

URLinks is a free link management tool built on the same concept as Google's internal "go links" — short, memorable names you type directly in your browser address bar to jump to any URL. Over 100,000 Googlers have used go links daily for 10+ years. URLinks brings that to everyone.

Unlike GoLinks ($8/user/month), Bitly (paid analytics, paid QR), Linktree (branded, limited), or Dub.co (usage caps), URLinks is free for all core features with no branding on user pages.

## Core capabilities

- **Go links**: Save any URL as a short name (e.g., `my/roadmap`, `work/standup`). Type it in the browser address bar. URLinks intercepts and redirects instantly.
- **URL shortening**: Create and share short links. Recipients type the name — no signup needed on their end.
- **Link-in-bio pages**: Public profile pages at `urlinks.me/{username}` with customizable blocks, themes, and social links. No URLinks branding. AI-powered customization.
- **QR codes**: Generate fully customizable QR codes for any link. Embed your logo, pick custom colors and gradients, choose dot and corner styles. Free, no watermarks, no limits.
- **Analytics**: Full click analytics — country, city, device, browser, OS, referrer, unique visitors, and daily breakdowns — all free. No paywalled tiers.
- **Groups**: Organize links into namespaces (`my/`, `work/`, `fam/`) with role-based access control.
- **Mobile web**: Full-featured mobile site — manage links, view analytics, edit profiles from any device.
- **Chrome extension**: Save pages in one click, autocomplete as you type, keyboard-first design.
