Ludr AI — Understand Any Screen

The core move is a single hotkey. Press it and Ludr freezes your screen, then you drag a box around whatever you need explained. Because it works at the system level, it runs over code editors, browsers, spreadsheets, and chat apps alike. No copy-paste. You aren't stuck moving content into a dedicated assistant window.

Every question becomes a thread rather than a one-off answer. You can reopen a thread later and keep asking in context, which matters when you're chasing a problem over several steps. The model remembers the earlier turns, so a follow-up doesn't need you to re-explain the original selection.

Inline edit rewrites a selection where it sits. Grammar, tone, and small code fixes happen without a round trip through a separate tool. That's the whole point. It's the feature that makes Ludr useful for editing inside messaging apps, browsers, and editors, since the corrected text lands back in the same field you were already typing in.

Hit the mic, speak your question, and Ludr transcribes it into the input box, stopping when you go quiet. Voice is handy when you want to ask about something you can't easily type. Hard to spell it out? Just say it. It keeps your hands off the keyboard.

Visual grounding means Ludr points at the specific elements it's discussing instead of describing them vaguely. On a UI review it can flag that a contrast ratio fails, that an element is misaligned, or that a focus state is missing, and it marks each item on the screen so you can see exactly what it means.

Select an image like a receipt and Ludr pulls the text and figures out of it. That turns screenshots and photos into usable data without retyping, which is the quiet workhorse feature for anyone who deals with scanned documents or pasted-in screenshots all day.

You can bind up to ten custom shortcuts to fixed prompts, so pressing one combo and dragging a region returns the same answer every time. It's aimed at repeated tasks like translating a page or summarizing an article. Set it once. Skip the retyping.

Your history, screenshots, settings, and prompts stay on your machine, and the site states that no analytics, tracking, or telemetry runs in the app. For anyone handling sensitive material, that's a meaningful difference from cloud-first assistants. It also means your threads live only on that one computer.
