Lensia

The AI assistant that lives in your browser and reads your screen.

Lensia — The AI assistant that lives in your browser Lensia is the fastest way to ask AI about anything on your screen. Press a keyboard shortcut, drag a box around any question, paragraph, or screenshot, and get a clear answer in seconds without switching tabs or copy-pasting. It works on every site in Chrome, from homework platforms like Canvas and Moodle to Gmail, Google Docs, dense PDFs, and the article you're reading right now. Open the sidebar when you want a longer conversation, or stick with the floating panel for quick captures. Why people use Lensia • Answer anything on your screen instantly. No tab-switching, no copy-paste. • Pick the right AI for the job, or let auto-routing pick for you • Stay focused with a clean, distraction-free workflow • Works on every site you already use, no special integrations required What's actually different about Lensia • Screenshot capture — drag a box around any text, image, or question on screen and ask AI about it. Most AI extensions only see what you paste; Lensia sees what you point at. • Multiple AI models with auto-routing — OpenAI, Anthropic, Google, xAI, and DeepSeek all in one place. Let the auto-router pick the best model for each prompt based on complexity, or override and pick yourself. • Floating panel + persistent sidebar — two surfaces in one extension. Quick captures get a floating panel that stays out of the way; longer chats get a dedicated sidebar with full conversation history. • Privacy Guard — sites can't detect tab switches, window focus changes, or copy/paste while it's on. Useful for monitored testing platforms and any time you don't want a page tracking your attention. • Auto-solve mode — work through a series of questions back-to-back; Lensia captures and answers each one automatically. Also included • Reasoning mode — toggle deeper thinking for harder problems • Web search with citations — pulls live results from the web before answering • Agent mode — let Lensia open tabs, read pages, and follow links to gather context • Custom Instructions — tell Lensia how to talk to you and what to remember Pricing • Free — try Lensia on real work without a credit card • Basic ($1.99/week or $5.99/month) — 10× the free allowance, advanced models, custom instructions, agent mode • Pro ($3.49/week or $9.99/month) — the highest usage allowance, plus reasoning, web search, and Privacy Guard Get started Install Lensia and try it on whatever you're working on next.
