Our rating

3.6/5

Ari is a thoughtful chief of staff with unusually clear privacy promises, but its party trick of agreeing times with other people's Ari only works when they use Ari too.

What is Ariso?

Ariso makes Ari, an assistant that works in the background from your calendar, inbox and messages. It writes a morning brief, preps you before each meeting, takes notes, and keeps a list of what you have promised people, closing items when it finds evidence they are done. Its contacts app is a personal CRM that builds itself from your meetings, email and conversations.

For scheduling, you ask Ari to find a time and it settles it with the other person's Ari; people without Ari get a booking page on your profile. You can reach Ari by text, email (CC or forward), the web, a Chrome extension that acts on sites you are signed in to, voice, in-person recordings and Oats, its desktop notetaker. Native iOS and Android apps are listed as on the way; for now the mobile app runs in your phone's browser. Teams use it in Slack and Microsoft Teams with Google Workspace or Microsoft 365.

Ariso was founded in 2025 in Santa Clara, California, by Erkang Zheng, who previously founded the security company JupiterOne.

Is Ariso worth it?

You told a friend you would send that article, promised a colleague the numbers by Thursday, and said you would find a date for dinner. A week later you remember none of it, and the dinner thread is still a dozen messages of "how about Tuesday?".

Ari is built for exactly that drift. It reads your calendar, inbox and messages, notices when you commit to something, and keeps the list until it sees you have done it. Ask it to find a time and, if the other person also has Ari, the two assistants agree on a slot between themselves; anyone else gets a link to your booking page.

The privacy setup is better than most in this category. Ariso says it never trains models on your data, even on the free plan; each user's data is encrypted with its own key, held in HashiCorp Vault; staff cannot read it without your permission; and closing your account deletes the key at once, with backups purged within 30 to 90 days. You can also ask for an off-the-record session that is never recorded.

The catch: Ari needs broad access to work, your calendar, email and contacts at minimum, and its SOC 2 Type II audit is still under way, not finished. The assistant-to-assistant scheduling is a closed loop with no public detail on how it handles people on other tools. Pricing is split across two pages with different plans, $25 or $100 a month for individuals and $1 per user per day for teams, and native phone apps have not shipped.

Our take: Ari makes most sense if you already live in your calendar and inbox and want one place that remembers your promises. The friend-to-friend scheduling is a bonus that pays off only once your circle signs up.

Where it earns its place

  • A manager with eight direct reports on Google Workspace

    Stop dropping the follow-ups I promise in 1:1s

    Connect calendar and email; Ari preps each 1:1, takes notes and lists what you owe each person, closing items overnight when it sees them done. Base costs $25 a month billed annually.

  • A group of friends planning a trip together

    Pick dates without a long group thread

    If everyone has Ari, ask yours to find a time and it settles the slot with each friend's Ari; friends without it can use the booking page on your profile.

  • A 30-person startup that works in Slack

    Give everyone meeting notes, prep and a shared view of projects

    Start on the team plan free for up to 6 months, then Startup at $1 per user per day, about $900 a month for 30 people. Individual conversations stay private from the employer.
