You don't have to cheat...

Halo sees your screen, hears the room, and understands the moment — then speaks up only when it matters. A quietly brilliant desktop companion for the work that actually counts.

The whisper engine

Halo speaks first.
Only when it should.

No prompt. No search. Halo just watches — then puts the one sentence you needed on your screen, quietly.

Capabilities

One companion.
Every context.

Halo isn't a tab. It's a layer. It follows you across apps, windows and workflows without ever asking to be the star.

01Vision
Halo Mascot

Sees every window. Understands the layout.

Halo reads your screen with spatial precision — code, tabs, docs and dialogs, all as one continuous surface of context.

02Hearing

Follows every voice in the room, in real time.

05Reasoning

One model, many postures — code, prose, tactics, math.

03Memory

Weeks of local context, kept quietly on-device.

04Presence
Altoption
S

Vanish and return with a single shortcut.

In the wild

Quiet wins,
every day.

Everyday User

Interviewer asked about system design. Halo surfaced my last week of notes without a search.

Halo didn't give me the answer. It reminded me of the mnemonic I made three days ago.

Caught the budget signal I would've missed. Closed the round on the same call.

Debug loop dropped from 40 minutes to 6. It saw the stale closure before I did.

It reminded me to reply to my mom. That alone paid for the beta.
