Ari
Your brain, at your fingertips.
Nine apps, one assistant — each drawing on everything Ari remembers.
Tap any app to open it — the dotted ones show a live preview. Even the wallpaper’s yours.
“I used to pay for Granola and Lindy separately. Ariso replaced both. My operations run like there's a 5–10 person team backing me up.”
Build or bring your agents.
Ari doesn’t just run your apps — it helps you stand up a virtual team. Build agents conversationally from every skill, tool, and connector you already have, or bring the agents you already run and see everything they do in one place.
Build agents, conversationally
BuildDescribe the job. Ari wires up the workflow from every skill, tool, and connector you already have — then runs it and manages it for you. No config files, no code.
Bring your own agents
BringAlready running Claude Code or agents of your own? Point them at Ari and every run, decision, and hand-off is tracked in one place — your whole agent team, visible.
This is the real thing — where you already work.
No new app to learn. Ari shows up in Slack and in your pocket and does the actual work — here it is, for real.
One system, not nine apps.
Anyone can bolt nine features onto a chatbot. What makes Ari an operating system is that the apps talk to each other — one intelligence that knows your whole context, so what happens in one place shows up where you need it in another. That’s the part a stack of point tools can never do.
A commitment you make on a call becomes a tracked follow-up, and nudges you before it’s due.
A pattern across your weeks becomes a specific, private coaching moment — not generic advice.
A new name in a call becomes a contact that fills itself in — and briefs you before you meet again.
It doesn’t just do things. It makes you better.
Every AI assistant can draft and answer. Ari also keeps track of everything you’re carrying — and quietly helps you grow. That last part is the whole point.
Runs your day
Prep for what’s next, capture every meeting, draft the reply, remember the detail. The busywork, handled.
Keeps you on top
Nothing slips — follow-ups chased, reminders fired, contacts and a journal kept current without a thought.
Makes you better
Weekly reflections show you the truth about your time, and a private coach helps you act on it — every single week.
Busy operators who stopped dropping balls
It lives in Slack, where you already work.
Ari OS isn’t a dashboard you have to remember to open. It’s a teammate in Slack that works in the background and comes to you — prepping you before a call, nudging a follow-up, dropping a reflection on Friday.
- Right inside Slack — no context-switch, no new tab.
- Proactive — it comes to you, you don’t go hunting.
- Private by default — your Ari, your data, never trained on.
