Siftlume

Summarize web pages, text and files into interactive visual summaries. Bring your own LLM key.

Siftlume turns long pages into summaries you can scan in seconds. Open an article, report or documentation page and click the Siftlume icon. You get a one-line TL;DR, the key figures and short takeaways, plus charts, timelines and diagrams when the content calls for them. Then ask follow-up questions, answered only from the source. WHAT YOU CAN SUMMARIZE • The page you are reading, or just a selection (right-click, then Summarize selection) • Text you paste • Documents and spreadsheets you open from your computer MADE FOR THE CONTENT • Numbers become charts, chosen from the shape of the data • Reviews get a verdict with pros and cons • Action items become a checklist you can tick • Processes and decisions become diagrams • Spreadsheet data gets filters that update instantly TOOLS • Refine in one click: shorter, more detail, action items, timeline, simpler • Change the length or language of a single summary • Copy or download as Markdown, listen, or print • Jump to a quoted passage in the original page • History of past summaries YOUR AI, YOUR KEY Connect the AI provider you already use with your own API key, or run a model locally on your computer.
