Windsor.ai: cost, fit and limits
Windsor.ai is a marketing data integration platform made by Windsor Group AG that connects more than 350 business platforms and sends the data to BI tools, spreadsheets, warehouses and AI chats, for analysts and agencies who build their own dashboards.
What to know first
Windsor.ai prices by data sources and accounts rather than by features, since all 350-plus connectors and all destinations are included on every plan. Basic costs $19 a month billed annually, Standard $99, Plus $249 and Professional $499, with Enterprise on request. A free tier starts as a 30-day trial and then drops to one source and one account, which limits long-term testing.

Who Windsor.ai is best for
Analysts with several data sources
Every plan includes all connectors and destinations, so the choice between tiers is about source and account counts, not about which platforms you are allowed to connect.
Teams that want German hosting
The pricing FAQ states hosting in Germany, and a SOC 2 Type II badge is shown on the privacy page, which helps with client questions about data location.
Marketers who ask questions in Claude
Windsor MCP connects the data to Claude and ChatGPT, so people can query marketing data in plain language without building a dashboard first.

What Windsor.ai does
- 350-plus connectors
- No-code connectors reach more than 350 business platforms, and the vendor says a sync can be set up in about a minute, which suits analysts with a long tail of sources.
- Destinations on all plans
- Data goes to BI tools, spreadsheets, warehouses and AI chats, with destinations included on every plan instead of being held back for the top tiers.
- Scheduled refresh
- Syncs run daily on Basic, hourly on Standard and every 15 minutes on Professional, which decides in practice how current a dashboard is when a client opens it.
- Dashboard template gallery
- Templates exist for Looker Studio, Power BI, Excel, Google Sheets and Tableau, which gives a starting layout once the connector work is done and saves the first design pass.
- Blending and normalization
- Data blending merges sources with schema mapping and normalization, so spend and clicks from different ad platforms land in one consistent set of fields for the dashboard.
How Windsor.ai handles your data
The pricing page FAQ says data is hosted in Germany, and the privacy page footer shows a SOC 2 Type II badge, though the policy text names no certifications. The privacy statement says data is kept as long as necessary to provide the services and does not give a fixed retention period. It makes no statement on whether customer data trains AI models, so the vendor's policy was not checked for this. API rate limits of 600 requests per minute and 10,000 per day are stated and are not tied to plans.
Where Windsor.ai falls short in practice
- Source caps bite early. Forever Free holds one data source and one account once the 30-day trial ends, and Basic allows 3 sources, so a marketer with five platforms needs Standard.
- No reporting layer of its own. Windsor.ai moves data into other tools. An agency that wants white-label client reports, portals or scheduled PDFs must pair it with Looker Studio, Power BI or another front end.
- Row limits not stated. The pricing page gives no row limit, so a heavy account cannot tell from the page how data volume affects fair use or performance on lower plans.

Windsor.ai: common questions
Does Windsor.ai have a free plan?
Yes. The free tier is a 30-day trial with 1 user, 10 data sources and 15 accounts, after which it becomes Forever Free with 1 data source, 1 account and 5 destination tasks. Paid plans start at $19 per month billed annually, or $23 billed monthly.
Which connectors does each Windsor.ai plan include?
All 350-plus connectors and all destinations are included on every plan. Plans differ in data sources, accounts, users, destination tasks and sync frequency. Check how many platforms you connect before choosing, since Basic allows 3 sources and Standard allows 7.
Where does Windsor.ai host data?
The FAQ on the pricing page states Germany as the hosting location. A SOC 2 Type II badge is shown in the footer of the privacy page. The privacy statement itself does not name hosting or certifications, so ask for the documentation if a client contract requires evidence.
How does Windsor MCP work with Claude and ChatGPT?
Windsor MCP for AI Insights connects Windsor.ai data to AI tools such as Claude and ChatGPT so users can ask questions about it in plain language. The pages opened do not list which actions the assistants can perform, so test a few real questions in the trial.
How often does Windsor.ai refresh data?
Basic syncs daily, Standard supports daily or hourly refresh and Professional offers a 15-minute scheduled sync. The pages opened do not state the refresh rate for Plus or the free tier. Match the plan to how current your dashboards must be.
