Overview

Windsor.ai transfers data from more than 350 sources to BI tools, spreadsheets, warehouses and AI chats. Its source directory includes Google Ads, Google Analytics 4, HubSpot, Salesforce, Shopify, TikTok Ads and Facebook Ads; destinations include Power BI, Looker Studio, Google Sheets, Excel, BigQuery, Snowflake, Tableau, PostgreSQL, MySQL, Python and Windsor MCP. This breadth can reduce the need to assemble separate connectors, though the number of sources and accounts supported depends on the plan.

Scheduled syncs, schema matching and incremental loading support repeatable data movement. Windsor MCP connects Windsor.ai data with ChatGPT, Claude and Copilot for analysis. Founded in Zurich in 2017, the company is headquartered in Baar, Switzerland.

Key features

Connectors and automation

Scheduled syncs and incremental loading suit teams that need refreshed reports without repeatedly transferring entire datasets; schema matching helps align data as it moves between systems. Cadence matters: Basic syncs daily, Standard and Plus add hourly syncs, and Professional supports 15-minute syncs. These tiers make Windsor.ai more compelling for routine reporting than for teams that require a faster refresh on a lower-cost plan.

AI analysis

Windsor MCP provides a route from connected data to ChatGPT, Claude and Copilot. That can suit analysts who want to examine pipeline data through those tools, but it does not change the source, account or sync allowances of the selected plan.

Security and support

Windsor Group AG says it completed a SOC 2 Type II audit and processes personal data in compliance with UK GDPR and EU GDPR. Customer data is encrypted at rest and in transit, with role-based access controls and separate customer data trust zones. Connector memory data is kept for up to 24 hours; disk cache is deleted after at least 20 days without access, with maximum retention of about three weeks. All plans include live chat, alongside documentation, ticket submission, a community portal and YouTube resources.

Pricing

Windsor.ai has a free plan, paid plans and a 30-day trial. The pricing note gives paid pricing from $19/mo (annual), while the plan prices below are monthly billed amounts; compare the billing term as well as the allowance when choosing a tier.

Forever Free: Free for one user, one data source and one account. After the 30-day trial, this is a narrow option for evaluating a single connection; scheduled sync backfills are unavailable.
Free (30-day trial): Free, with one user, 10 data sources, 15 accounts, five destination tasks and 30-day history. It offers room to assess a broader workflow, but its 30-day duration and single-user allowance limit its use as a team plan.
Basic: 23.00 USD per month, billed monthly, with unlimited users, three data sources, 75 accounts, five destination tasks and daily scheduled syncs. It fits a small recurring pipeline, but the three-source and five-task caps constrain broader reporting.
Standard: 118.00 USD per month, billed monthly, with unlimited users, seven data sources, 75 accounts, unlimited destination tasks and daily or hourly syncs. This is the more practical step for teams with several destinations or a need for hourly refreshes, though it still caps sources at seven.
Plus: 299.00 USD per month, billed monthly, with everything in Standard plus 10 data sources and 200 accounts. It suits larger account portfolios, but adds no faster sync cadence than Standard.
Professional: 598.00 USD per month, billed monthly, with everything in Plus plus 14 data sources, 500 accounts, auto-add accounts and daily, hourly or 15-minute syncs. It is aimed at high-volume or freshness-sensitive pipelines; its higher price is difficult to justify if daily or hourly updates suffice.

Across the tiers, the free plan is constrained by a single source and account, while paid plans scale source and account capacity and, at higher levels, task counts and sync frequency. The API is limited to 600 requests per minute and 10,000 per day, a relevant ceiling for API-driven workflows.

Platforms

Windsor.ai runs on web and provides an API. The connector ecosystem spans sources and destinations, but the API limits may matter to integrations that make frequent requests.

Who it's for

Analysts can use Windsor.ai to consolidate data for automated reporting; agencies can build client dashboards; and data teams can manage recurring pipelines across tools. The plan structure is most suitable when the source and account counts fit within a defined tier. A team needing many sources, more frequent syncs or substantial API throughput should check those limits before committing.

Pros and cons

Pro: More than 350 sources and destinations spanning BI, spreadsheets, databases, warehouses and AI tools can support varied reporting setups.
Pro: Scheduled syncs, schema matching and incremental loading support repeatable data movement, with 15-minute syncs available on Professional.
Pro: Live chat support is included across all plans, with additional documentation, ticket, community and video resources.
Con: Forever Free allows only one source and one account, and lacks scheduled sync backfills, so it is not a substantial ongoing multi-source tier.
Con: Paid plans cap sources and accounts, and Basic is limited to five destination tasks and daily syncs; teams with wider or more current pipelines must move up tiers.
Con: API requests are capped at 600 per minute and 10,000 per day, which can restrict high-volume API use.

Alternatives

Email Marketing Analytics Software is a broader category to explore when comparing tools for that use case.

Consider Singular instead if its free plan's 15,000 paid conversions and per-conversion pricing model better match your conversion-tracking needs. AnyTrack is a fit to compare when a free allowance of 5,000 sessions per month, one website, one ad platform integration and one conversion source is enough. For email-focused needs, Bluey Email offers a free plan with 500 emails per month, 500 contacts, forms, one automation and one landing page; OptiKratos Email has a free tier of 15,000 emails per month.

Dreamdata is worth comparing if its free plan's two-month user history, five seats, three stage models, two notifications and one sync meet your needs. Bird Analytics, Sendlens and Advanza are other alternatives to consider.

Verdict

Choose Windsor.ai if your team needs no-code movement across a wide range of sources and destinations, with scheduled syncs and a plan that accommodates its source and account counts. Its main advantage is breadth paired with automation; its chief drawback is that multi-source capacity and faster refreshes require higher tiers, while the permanent free plan is limited to one source and account. Look elsewhere if those caps, the API ceiling or the cost of the cadence you need do not fit your pipeline.
