Siftlume turns long pages into summaries that you can skim through in seconds.

Open an article, report, or document page and click the Siftlume icon. You get the main points in a single line, important numbers, and key takeaways, along with charts, timelines, and diagrams when the content requires it. You can then ask more questions, with answers solely based on the original content.

WHAT YOU GET IN THE SUMMARY

• The page you are reading, or just the section you highlight (right-click → Summarize selected text)
• The text you paste in
• Documents and spreadsheets opened from your machine: PDF, CSV, Markdown, TXT, HTML, JSON

FOUR WAYS TO READ

• Summary: quickly grasp the main points
• Explanation: understand how it works, with everyday examples, common misunderstandings, and terminology
• Critique: compare each claim with evidence in the article, pointing out weaknesses and items that require verification
• Action: a to-do list with deadlines, requirements, and risks

Choose your reading style and length (short, medium, detailed) before analyzing, or change it directly on the results.

STRUCTURE BY CONTENT

• Data as charts, selected by data type
• A review article with conclusions along with pros and cons
• Tasks into a checklist that can be checked off
• Processes and decisions into diagrams
• A debate with a map of arguments: who said what, based on what evidence
• Shopping selections with a scoring table based on criteria, along with step-by-step cost calculations
• New policies with before/after tables and perspectives from each party
• A programming guide with line-by-line code explanations
• Spreadsheet data with instant filter updates, no need to call AI again

TOOLS

• One-touch refinement: shorter, more detailed, to-do list, timeline, simpler
• Change the length or language of each summary
• Copy or download in Markdown format, listen, print or save as PDF
• Click on citations to jump to the correct section in the original page
• History of summaries

YOUR AI, YOUR KEY

Connect your AI provider using your own API key: OpenAI, Anthropic Claude, Google Gemini, OpenRouter, Groq, DeepSeek, Mistral, xAI, and OpenAI-compatible services. Or run the model directly on your machine with Ollama or LM Studio, no key required. Requests go straight from the browser to that provider, without passing through any Siftlume servers.

PRIVACY BY DESIGN

• No account needed, no statistics, no tracking
• API keys, settings, and history only reside in your browser
• The website is only read when you request a summary
