Ocly Buy once · $99

macOS overlay · excluded from screen capture

Answers on your screen.
Not on theirs.

Ocly reads what's on your display, listens to the call, and writes your next line in a floating panel. That panel never shows up in a screen share, a recording, or a screenshot.

Interviewer “…so how would you handle the overflow case without using a 64-bit int?”

Sure — let me think out loud. I check before I multiply, not after.

If out > MaxInt32/10, the next out*10 is already gone, so I return 0 there. Same guard on the negative side.

That keeps everything in int32 — O(log n) time, O(1) space.

⌘[ capture ⌘] send
The same second, two views. macOS content protection removes the panel from the capture stream at the window-server level — it isn't hidden behind a window or parked off-screen. There is simply nothing in the pixels the other side receives.

Three inputs, one panel

It watches, it listens, it answers.

Sees

Whatever is on your display

One keystroke grabs the screen and hands it to the model as an image. The question on the shared doc, the failing test, the slide you were just asked about — it goes in as-is.

⌘[

Hears

Both sides of the call

Ocly taps system audio and streams it to Speechmatics for live transcription, so it always knows what was just asked — including the part you half-missed.

⌃⇧A

Answers

In your voice, in the panel

The reply lands in the overlay written the way you'd say it — with code fenced and mermaid diagrams rendered inline, ready to read off or talk through.

⌘]

Specification

Built to disappear.

Invisibility

Out of every capture

Zoom, Meet, Teams, QuickTime, ⌘⇧4 — the panel is excluded from all of them. It stays on top, follows you across Spaces, and survives full-screen apps.

Control

Never touch the mouse

Vim-style hotkeys move, resize and scroll the panel. Your cursor stays exactly where the interviewer expects it: on the code.

Voice

It answers as you

Write your own system prompt — your background, your stack, your way of explaining a trade-off. Ocly speaks in first person, not like an assistant.

Diagrams

Mermaid, rendered live

Architecture sketches, state machines, an array with the pointers marked. Drawn in the panel while you talk, so you describe a picture instead of prose.

Models

Claude, GPT or MiniMax

Switch provider mid-session. Use the fast cheap model for chatter and the strong one for the hard question, on the same keys.

Storage

Everything stays local

Sessions, keys and prompts live in a store on your Mac. Nothing leaves the machine except the API call you're paying for.

Muscle memory

Fourteen keys, no cursor.

Every binding is remappable. These are the defaults.

Bring your own keys

There is no Ocly server.

No account. No sign-in. No usage dashboard, because there's nothing to meter. You paste your API keys into the app, they're stored on your Mac, and every request goes straight from your machine to the provider you picked.

We never receive a prompt, a screenshot or a transcript. Not by policy — by architecture. There's nowhere for it to go.

Any key you have works. Your rate limits, your spend cap, your choice of model. No questions asked.

Download Ocly for macOS

macOS 12+ · Universal (Apple Silicon & Intel) · 206 MB · Windows build in progress, free when it ships

First launch: the build isn't notarised yet, so macOS will stop it once. Right-click Ocly in Applications, choose Open, then confirm. After that it opens normally. Ocly also needs Screen Recording and Microphone permission in System Settings → Privacy.

Not included: API credits. You pay Anthropic, OpenAI or Speechmatics directly at their prices — usually cents per session. We'd rather not stand in the middle and mark it up.

Straight answers

Questions worth asking.

Is it genuinely invisible on a screen share?

To software, yes. The panel is marked as protected content, so the macOS window server leaves it out of every capture stream — conferencing apps, screen recorders, screenshots alike. To a person standing behind you, obviously not. It's invisible to capture, not to eyes.

Does it work on Windows?

Not yet. Today it's macOS 13 or later on Apple Silicon. The Windows build is in progress and lands as a free update on the same licence.

What does a session actually cost to run?

Whatever your provider charges. Screenshots are the expensive part; an hour with a mid-tier model and live transcription typically lands between a few cents and a couple of dollars. You set the spend cap in your provider's console, not here.

Can you see my screen or my transcripts?

No. There's no backend to send them to. Screenshots and audio go directly from your Mac to the API you configured, and sessions are stored in a local file.

I already pay for Claude Pro / ChatGPT Plus. Is that enough?

No — consumer subscriptions and API keys are separate products. You'll want a key from console.anthropic.com or platform.openai.com. Both take a couple of minutes and bill per use.

Will you turn this into a subscription later?

Not for anyone who already bought. The licence you buy today covers every future version. If pricing ever changes, it changes for new buyers.

Walk in prepared.

The panel is already open. They just can't see it.
