Top 5 Cassidy AI Alternatives (2026)

Companies look for a Cassidy AI alternative for reasons Cassidy documents itself. Cassidy is its own web application; to bring an Agent into Microsoft Teams, someone creates a bot in the Teams Developer Portal and a Teams admin approves it, and Cassidy’s Teams guide says it can no longer create that bot for you. Its Agents answer from the Knowledge Base your team fills, and the personalization each user sets up does not apply in Teams. Its pricing page shows no price for either plan, and every chat and Workflow run uses credits. And its privacy notice says personal data is stored, hosted and processed on servers in the United States.

For a company that runs on Microsoft Teams, that adds up to a second tool, knowledge someone has to feed and a budget you get from a sales call. Here are five alternatives. For the direct head-to-head, see amaiko vs Cassidy AI.

1. amaiko: AI that remembers, inside Teams

amaiko lives in Microsoft Teams, in the chat your company already uses. There is no separate app tab, no browser extension and no bot for your IT to build.

amaiko builds a persistent corporate memory. Every night it consolidates your team’s conversations into lasting company knowledge: projects, customers, decisions and who knows what. It learns how each person works and gets better every day. When someone leaves, what they knew stays. amaiko teams spend 35% less time searching, and new hires get up to speed 57% faster.

That memory feeds a multi-agent network: specialists for email, calendar, documents, research and your business systems, from a growing marketplace. You pick them; nobody has to build an agent first.

And amaiko works before you ask. Active Inbox reads incoming email and flags what needs attention, and flagged emails become to-dos. It is part of the plan, so nobody has to build it as a Workflow or pay for it in credits.

amaiko is GDPR-compliant and hosted in Germany on its own infrastructure, not in the Microsoft cloud, with AI processing only inside the EU. Details are on the security page. It costs €41.58 per user per month billed annually (€499 per user per year), or €49.90 monthly, with unlimited tokens. A 10-person company pays €4,990 a year, a figure you can read off the pricing page today.

2. Dust: agents you build, billed in credits

Dust is a platform for building AI agents on company data. Its Business plan is for teams of up to 100 people: the Pro seat costs €24 per month billed yearly (€30 monthly) with 8,000 credits per seat per month, and the Max seat €120 billed yearly with 40,000 credits. Dust offers US and EU data residency. In Teams, Dust runs as a bot that an administrator uploads as a custom app. For your team that means agents someone has to design, and a credit allowance to watch.

3. Glean: enterprise search, price on request

Glean is an enterprise search and AI agent platform. Glean does not publish prices: its pricing link leads to the home page, whose customer stories are large enterprises such as Booking.com with 14,000 employees. For a mid-sized company, the budget conversation starts with a sales call.

4. Onyx: open source, if you run it yourself

Onyx is an open-source AI search and chat platform. Self-hosting is free, and its Business plan costs $20 per user per month billed annually in Onyx’s cloud, with 40+ app connectors. The pricing page lists a Slack integration; for Microsoft Teams, Onyx’s documentation describes a connector that indexes the files of your Teams sites. For a Teams-based company that means your team works in Onyx’s own window, and self-hosting means your engineers run, update and secure it.

5. Lindy: an assistant that lives in Slack

Lindy describes itself as an AI assistant that “lives in your Slack”. Microsoft Teams is one of the apps it connects to, so it can act in Teams when you ask it to. Its pricing page shows Plus at $29.99 per user per month with 3,000 credits and Pro at $99.99 with 15,000. Every seat’s credits go into one shared pool, and when the pool runs out, Lindy pauses credit-using actions until the next billing cycle. For a Teams company that means an assistant whose home is Slack, and a credit pool to watch.
