Burn 451 vs Savr

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.

Savr is a free progressive web app for saving online material to read later through a hosted or self-hosted setup. Saved articles and images remain available offline on the device, either in a cleaned reader view or as the original page. Users can store web articles, pasted HTML, Markdown, or plain text, and upload PDFs and images. Content can be added in the app, with a bookmarklet or URL, or shared from an Android browser to the installed PWA. On iOS, the documented method uses a Shortcut that opens Savr in a browser. Collections support favorites, themes, adaptive reading-time estimates, and read-only public copies. Optional summaries work with OpenAI-compatible providers, including Groq, OpenAI, Gemini, and local or custom servers. Optional sync can use Dropbox or Google Drive. Savr says content is local, with no required account or server-side storage. The hosted app collects anonymous usage events by default with an opt-out; self-hosted builds have telemetry off. The free plan costs nothing with no published usage limits.
