About Ari
Ari is an AI work assistant from Ariso, officially positioned as an "AI chief of staff." It brings together meeting notes, Slack messages, emails, documents, decisions, and commitments into a single unified memory. Users can ask questions in natural language directly in Slack, Teams, on the web, or via SMS, and answers come with their sources. Ari also follows up on to-dos and offers prompts. On security, the official website states that every message is encrypted with a per-user key, data is not used to train models, and users can retain or delete data on demand. Developers can use the Ari MCP Server to connect meetings, follow-ups, reminders, and organizational memory as tools into Claude, Claude Code, or ChatGPT.

Meeting notes, Slack messages, emails, and documents are connected into a single unified memory; when you ask a question, you get an answer with its sources, not a list of search results.

Ask questions by messaging directly in Slack, Teams, on the web, or even via SMS—no need to switch tools.
Follow-ups and reminders
Ari follows up on your to-dos and gives you hints when things get difficult.
Per-user encryption
Every message is encrypted with a key that belongs only to you, is not stored centrally, and is not used to train models.
You control your data
Keep what you need and delete what you don't; your conversations are not monitored.
