Features
Hit one hotkey to grab the entire screen, or another to draw a selection around just the part you care about. The AI analyzes the captured image, understands the full situation, finds the problem, and returns a complete solution. No typing or speaking required. Stuck on a bug instead? It can pinpoint exactly where the bug is so you can fix it yourself.
See it on a live coding interviewHidini was built for high-pressure moments, so controlling it never gets in the way. Toggle the overlay on or off, slide it anywhere on screen, resize it on the fly, or trigger any feature in a single keystroke. Every action maps to a global hotkey you can fully customize to match your muscle memory.

Translucent mode makes the entire app transparent so your screen behind it stays visible through the overlay. High-contrast mode switches to an opaque UI in any accent color you want. Click-through lets you select and interact with anything beneath the Hidini layer as if it weren't there, while still seeing it on top.
Drop as many sticky notes as you need, exactly where you want them. Drag them around, resize them from any corner, scale the text from tiny to large. Notes live above every other app, follow you across Spaces and full-screen workspaces, and toggle on or off with a single shortcut. They share the same invisibility layer as the rest of Hidini, so nobody on your call ever knows they exist.

High-contrast mode isn't locked to one look. Open Settings and dial in any accent color you want. Maximum readability, completely on your terms.
Invisibility is the default, but you own the switch. When you want to walk someone through your setup or demo a workflow, flip one toggle and Hidini appears on screen sharing instantly. Flip it back and it vanishes.
Drag, resize, and snap Hidini to any corner or edge of your screen. Global hotkeys let you reposition and resize on the fly, mid-interview, in under a second. No mouse, no trackpad, no interruptions.
Expert-level answers streamed in real time from Claude, OpenAI, Gemini, or a fully local model, rendered in a floating overlay that operates below the screen capture layer. Any screen sharing software (Zoom, Meet, Teams, Discord, OBS, and others) physically cannot access it; the overlay doesn't exist in their rendering context.
