Burn 451 vs Linkpack

Burn 451 is a read-later app that puts saved links on a schedule and turns retained items into a searchable knowledge base. A link begins in Flame for 24 hours; opening it moves it to Spark for 30 days, and users can move it to Vault for permanent retention. The free tier permits five Flame saves per day, 30 Spark items, 100 Vault items and 30 MCP requests per day. Pro costs $4.99 a month and removes limits on Spark items, Vault items and MCP requests. Pro also includes AI summaries and decision cards, voice notes, YouTube transcripts, automatic Vault tagging, full-text search and Markdown export. A 26-tool MCP server can search saved content and manage the queue in Claude, Cursor and Windsurf; the service also offers a REST API. Users can save links through the web app, Chrome extension, iOS share sheet or Safari extension for Mac. The maker describes Burn 451 as a personal tool for triaging unread links rather than maintaining an enduring bookmark archive. The Web Clipper requires a free account to sync saves across devices.

Linkpack is a tool for saving, reading, organizing, and sharing links. Links can be captured through the iOS app, Chrome or Firefox extensions, or by dragging and dropping them into the filesystem. Linkpack says saved links stay synchronized between the app and the user’s Dropbox folder. Users can group links into Linkpacks and track reading progress, while narration supports hands-free reading. Each Linkpack can receive a unique URL for sharing or embedding in a blog. The service lists Free and Linkpack PRO plans, but no plan prices are provided. It is available through extensions and iOS. Linkpack was founded in 2015 and is headquartered in Thessaloniki, Greece. Its terms limit use to people aged 18 or older. The privacy policy says personal information is not transferred, sold, or rented to third parties for marketing. Sharing a Dropbox folder involves collecting file internet addresses, creation dates, the user’s full name, and OAuth credentials used to download the folder’s files.
