Shelf: Save Links to Telegram

- **Shelf** is a free tool that lets users save web links directly to a Telegram chat, acting as a personal bookmarking or read-later service. It runs as a Telegram bot (@useshelfbot) and a browser extension. - **Telegram** is a popular cross-platform messaging app known for its privacy features, cloud-based syncing, and support for bots — automated accounts that can perform tasks like saving links, sending reminders, or fetching data. - The product sits in the same category as services like **Pocket**, **Raindrop.io**, or **Notion Web Clipper**, but distinguishes itself by using Telegram as the storage and access layer. This is useful for heavy Telegram users who want to keep bookmarks inside an app they already use daily, rather than maintaining a separate service.
