Not another AI app.
A category of its own.

Open-source agents like OpenClaw and Hermes are genuinely capable. They give you gateways, schedules, self-improving skills, and computer-use that runs commands on your behalf.

What Halo adds. Halo's brain runs on your Mac, and its proactivity is grounded in what you were actually doing. It keeps an ambient memory of your screen and your calls, so when it nudges you, it already knows the context. Every action is risk-gated and asks before it acts. And when something can't wait, Halo reaches you on your phone over an end-to-end encrypted link, and you reach back the same way, never a shell exposed to inbound messages.

superwhisper and Wispr Flow do on-device dictation really well, with custom modes. Cotypist does on-device autocomplete. Each one does its single thing nicely.

What Halo adds. On Halo, dictation is just one part of a single companion. Speak anywhere on your Mac, and the same assistant also finishes your sentences with ghost autocomplete in any app, rewrites a clumsy line, drafts a reply, and runs inline macros. It writes in your voice because it draws on your own memory.

Dictation apps like superwhisper transcribe what you say into the mic, but they won't handle a meeting or an audio file. The tools that do record meetings, like Otter and Granola, send your audio to the cloud.

What Halo adds. Halo records any call or meeting with a single shortcut, transcribes it right on your Mac, and separates the voices into a clear map of who said what. You get meeting prep beforehand, and a clean summary the moment you hang up, and all of it folds into a memory you can search later. The audio never leaves your Mac.

This is the part the point tools simply don't have. Dictation apps forget the moment they finish typing. Autocomplete apps keep no history. Cloud agents remember inside a chat, on someone else's server.

What Halo adds. Halo turns what crosses your screen and what's said on your calls into a private, searchable memory. It keeps the meaning and never the pictures, and all of it stays on your Mac. Ask in plain words: what was that error last Tuesday, what did Sarah say she'd send, what did I read about that vendor. You get the answer, with its sources.

Text-expander apps insert snippets and dates where you type. Useful, but narrow.

What Halo adds. Halo runs inline /macros right where you type: dates, math, snippets, and AI transforms that rewrite or reshape your text, all on your Mac. They live inside the same assistant that dictates, autocompletes, records, and remembers, so there's nothing extra to set up.
