Legend: Instant Meaning for Any ID or Code

Legend is your personal key-value store and glossary for the web. Ever come across an ID, code, ticket number, account number, or internal acronym that means something to you or your team, but nothing to everyone else? With Legend, save the meaning once and retrieve it instantly whenever you see it. No more switching tabs to search a spreadsheet. How it works: Add a key and its meaning in Legend. Visit any webpage where that key appears. Select the key. Legend instantly shows your saved meaning in a tooltip. For example: 66956225471 → AWS-Account#86 TXN-4471 → Transaction ID of client Acme ORD-58213 → Customer shipment - India-KA-BLR CLNT-7790 → Meridian Corp, priority client Legend is designed for information that isn't searchable on Google because the meaning is specific to you, your team, or your organization. Think of it as a private dictionary for your own jargon, abbreviations, and shorthand. Whether you are a cloud engineer decoding account and subscription IDs in the AWS or Azure console, a support engineer reading case references in a ticketing tool like Jira or Zendesk, a finance analyst working through invoice and cost centre codes, or a new joiner learning the shorthand your company invented, Legend turns a lookup into a text selection. Features: - Instant definition lookup by selecting text on a webpage - Personal key-value store, glossary, and dictionary in one - Add, edit, search, and delete entries - Optional "Suggest add" to annotate a new code when selected text has no saved meaning - Works with text fields and modern web editors - Supports content inside embedded frames - Import and export your entries as JSON - Light and dark themes - Tooltip stays readable regardless of the webpage's theme Your entries are stored locally in Chrome using the extension's local storage. Legend doesn't need a remote account or backend to work. Your account IDs, client names, and internal notes never leave your machine. Built for anyone who regularly works with identifiers, codes, references, or terminology that only makes sense in their own context.
