Slack App
Shorten URLs without leaving Slack. The /u2l command creates branded short links, searches your links, and shows recent activity — in any channel.
The U2L AI Slack app brings your link shortener into every conversation: paste a long URL, get a branded short link back in seconds — visible only to you until you share it.
Commands
| Command | What it does |
|---|---|
/u2l <url> | Shorten a URL |
/u2l <url> <alias> | Shorten with a custom alias (e.g. /u2l https://example.com/launch launch24) |
/u2l list | Your 5 most recent links with click counts |
/u2l find <query> | Search your links by slug, title, or destination |
/u2l connect | Link your U2L account |
/u2l disconnect | Unlink and revoke the Slack API key |
/u2l help | Command reference |
All replies are ephemeral — only you see them, so shortening in a busy channel adds no noise.
Connecting your account
The first time you run /u2l, the app replies with a one-time connect link (valid 10 minutes). Opening it takes you to your U2L dashboard, where one click creates an API key labeled Slack bound to your Slack user. The key is created server-side and never displayed; every plan (including free) works.
Each workspace member connects their own U2L account — links you create in Slack belong to you, count against your plan, and appear in your dashboard like any other link.
Revoking access
Two ways, same result:
- Run
/u2l disconnectin Slack, or - Revoke the Slack key in Settings → API
Either kills the credential immediately. Run /u2l connect any time to relink.
Installing to a workspace
Anyone can install the app with the Add to Slack link — a standard OAuth flow that only requests the commands scope. The app cannot read messages, channels, or files; it only receives what you type after /u2l.
