Native macOS app · No subscription required
AI copilot for technical interviews.
Invisible to screen sharing.
A native macOS overlay that gives subtle solutions to the problem on your screen or the question just asked, and keeps your notes alongside.
Everything you need to ace
interviews and live tasks.
One invisible overlay holds four tools: live transcription, AI hints, screen analysis, and full keyboard control. Every hint is built from your CV and the job posting, so what lands on screen fits your background and what the role is screening for.
Personal context
Best out of the box.
Even better once it knows you.
The hints work from first launch. Hand over your CV and the job you applied for and they start pointing at what you have actually shipped instead of reciting a textbook answer.
Import your CV
PDF, Word, RTF, or text. The app turns it into a profile of your roles, stack, and achievements.
Paste the job link
Hidini reads the posting and summarizes the company, the role, and what they screen for.
Every answer uses both
Hints, screen analysis, and suggested replies all run with that context in the prompt.

What Hidini does not do
- Hidini hides the overlay from screen capture, not from the room you are in. Anyone looking at your physical display, or a second camera pointed at it, still sees everything you see.
- Hidini is macOS only. There is no Windows, Linux, iOS, or browser version, and there is no browser extension.
- Hidini does not answer for you. It puts a transcript, a hint, or a screen analysis in front of you, and you still decide what to say and what to write.
- Cloud providers need a working internet connection. If you want to stay offline, run a local model through LM Studio, Ollama, or Jan instead.

Note Groups - Organized Invisible Notes You Can Switch in One Keystroke
Invisible sticky notes are now organized into named groups. Only the active group is on screen, switching between them takes one keystroke, and everything stays invisible to screen sharing.
Notes Feature Updates - Screenshots and Highlighted Code
Paste a screenshot straight into a sticky note, or drop in a code snippet and watch it format itself. Both stay invisible to screen sharing, and neither one slows your notes down.
