Ash — Didn't read it? It burns. No guilt, no clutter.

FAQ
What is Burn 451?
A free bookmark manager that gives every bookmark a 24-hour countdown. Read it and it becomes a Spark. Ignore it and it burns to Ash. What survives goes to your permanent Vault — a curated knowledge base you can expose to AI agents via MCP.
How do I scan my bookmarks for free?
Visit burn451.cloud/scan, export your Chrome bookmarks (chrome://bookmarks → ⋮ → Export), and upload the HTML file. You'll see total count, duplicates, top domains, and year-by-year timeline — all free, instant, and 100% private.
Is Burn 451 free?
Yes, completely free on iOS and Web. No subscription, no credit card, no sign-up required.
What happens after 24 hours?
Unread bookmarks burn — they move to Ash. This is by design. The 24-hour countdown forces you to decide what's worth your time instead of hoarding links you'll never read. No guilt, no clutter.
What is the Vault?
Your permanent knowledge base. Articles you promote from Spark to Vault are stored forever — organized into collections, searchable, and accessible to AI agents like Claude via the MCP server.
Is Burn 451 a Pocket alternative?
Yes. After Pocket shut down in July 2025, Burn 451 is a modern alternative built for how people actually read online. Unlike Pocket, Burn doesn't let you hoard — every bookmark gets 24 hours. Plus it's AI-native with MCP support, so your saved articles work as a knowledge base for AI agents.
What is the MCP server for?
The Burn MCP server (npx burn-mcp-server) exposes 22 tools so AI agents like Claude, Cursor, and Windsurf can search your vault, manage bookmarks, and analyze your reading patterns.
