Research & write without losing context
LastBrowser turns the browser into a full writing studio: in a 70/30 split-view you read sources while creating summaries, scripts or social threads with Sidekick.
70/30 Split-View
Read the source article, PDF or whitepaper on the left, while Sidekick drafts outlines, quotes and summaries on the right — no tab switching required.
Social Thread Generator
Turn long blog posts or papers into crisp, readable threads for Twitter/X, LinkedIn or newsletters with a single click.
Paper & PDF Summarizer
Lengthy scientific publications are compressed to key findings, methods and results — including source references.
Focus Mode (Ctrl+B)
Hide all sidebars and controls with a single keystroke to focus fully on reading and writing.
Direct Markdown Export
Export structured notes and AI answers directly to Markdown for Obsidian, Notion, iA Writer or your blog.
Full Copyright Protection
Your notes and manuscripts are never sent to third-party servers. With local Ollama models every word stays offline on your PC.
