Burn451 is a reading tool that helps you save links, read them later, and decide within about 24 hours whether to keep or let go. Too many saved pages never get opened. Burn451 gives each new save a short window: open it in a clean reader, then keep it or release it. What you choose to keep can move into Spark and then Vault, so your library stays intentional. What you can do: • Save links from Safari or any app with the Share Extension. • Read in a clean, focused reader without ads or clutter. • Find pages again with full-text search. • Organize saved pages with tags. • Keep a Spark and Vault workflow for what is worth keeping. Optional AI-assisted features can help you review what you saved. They are not included for every account, and this listing does not promise free AI for all users. You decide what stays. Unread items can expire. Burn451 does not permanently delete every link after 24 hours. If a page cannot be extracted, that save is held and does not burn. You can retry extraction or paste the text. Listen with system text-to-speech in the reader. Export from Vault, including Markdown and a direct Obsidian folder export, is available and is not sold as a Pro-only feature. Full-text search is available to every account. Privacy first. Your reading stays yours. No ads. No selling your data.
