AIOS vs Cassidy AI: which one to choose?
Cassidy AI is a serious platform for giving business teams the means to build their own agents on top of a company knowledge base. The AIOS is not something you build: it arrives configured, on a dedicated server in France, with a team that sets it up with you.
Cassidy AI (New York, founded in 2023 by Justin Fineberg and Ian Woodfill) is a no-code AI agent platform aimed at business teams. The core idea is sound: connect a company knowledge base to the tools where information already sits, Google Drive, SharePoint, Salesforce, Slack and a hundred others, then let non-technical teams build assistants, multi-step workflows and meeting notes on top of it. The company raised a Series A led by HOF Capital in September 2025 and puts forward operationally complex sectors: insurance, manufacturing, construction, logistics, professional services.
Cassidy and the AIOS share the same conviction, that AI should do the work rather than merely answer, but they do not serve the same organisations. Cassidy is an enterprise platform: it assumes business teams who build, an IT function that governs access, and a volume that justifies tracking credit consumption. The AIOS speaks to a business owner with neither a spare team nor an IT department: it arrives already assembled, wired into their email, their quotes and their clients, on a server that is theirs, configured by our team during the 7-day trial.

When to choose what
When to choose Cassidy AI
- You are a structured company, with business teams who have time to build agents and an IT function to govern access
- Your information already sits in Google Drive, SharePoint, Salesforce or Notion, and your first need is to make it searchable everywhere
- You want to deploy one assistant across Slack, Teams, the browser and Office files, for dozens of users
When to choose the AIOS Recommended
- You run a small business and nobody there will curate a knowledge base or maintain workflows
- You want your data to stay on a dedicated server hosted in France, never sitting alongside another client's
- You prefer a fixed subscription and a human contact in your own language to a credit meter and a quote form
Cassidy AI is a good platform, and for a company whose information is already structured in its tools and whose business teams want to build, it is a coherent choice: the connected knowledge base is its real strength. The AIOS answers a different problem. It asks you neither to build, nor to govern, nor to count: it arrives assembled, on your server, and it works from the first week.

Your questions, our answers.
Cassidy is no-code, so why talk about setup work?
No-code does not mean no work. Answer quality depends entirely on the knowledge base: you have to choose the sources, retire stale documents, manage access rights and keep it current, otherwise the agents answer with last year's procedure. Then you have to describe each process, test the agents, correct their drift and rework them when your ways of working change. That is a real job, held by someone on your side. The AIOS moves that job to us: you describe what you want to delegate, our team sets it up, and you adjust afterwards with a single sentence.
Is credit-based billing a problem?
It is a sound model for industrial, predictable volumes: you pay for what your agents consume, and the free plan lets you try without commitment. It gets uncomfortable when usage is irregular, or when every new automation idea turns into another line of consumption, which quietly pushes you to hold back at exactly the moment you should be delegating more. The fixed AIOS subscription removes the question: you delegate as much as you want without watching a meter, and you know your bill in advance.
Where does my data sit in each case?
Cassidy is a US cloud SaaS that puts forward serious certifications, SOC 2 Type II, GDPR and HIPAA, and states that customer data is not used to train models. Your knowledge base nonetheless stays hosted on shared infrastructure in the United States, with no France hosting option announced to date. The AIOS is installed on a server dedicated to your company alone, hosted in France: your documents, your history and your company memory never sit alongside another client's. For a law firm, an accounting practice or any regulated profession, that is often the deciding point.
