ToolsGavel verdict
The flattest pricing in the connector category, worth it once you'd otherwise be paying per seat or per source, with a genuinely useful attribution suite thrown in rather than sold separately.
Audited price: $19/mo billed annually , $23/mo month-to-month (advertised: $23/mo (Basic, billed monthly)) — verified 2026-10-30.
Best for: Growing teams and small agencies who want one predictable monthly price across sources and seats, plus built-in attribution modeling instead of a bolt-on tool
What we liked
- Every paid plan, including the $23 entry tier, includes the full connector and destination catalogue plus unlimited users, no premium-connector or per-seat upcharge
- 300+ connectors reaching the usual Looker Studio, Sheets, Excel and BigQuery destinations, plus ChatGPT, Claude and Perplexity for plain-language queries against live campaign data
- Built-in multi-touch attribution modeling (first-click, last-click, linear, Markov, algorithmic) ships on every plan instead of requiring a separate tool
- Reviewers on G2 consistently praise how easily accounts connect and the accuracy of the auto-generated data schema
What to watch
- Steep jump from Basic ($23/mo) to Standard ($118/mo) with nothing in between, a recurring complaint in G2 reviews asking for a mid-tier
- Hourly refresh needs Standard or above, and 15-minute syncs are locked to the $499/mo-plus Professional plan
- Support experience is inconsistent across platforms: G2 reviewers name staff and praise response times, while Trustpilot reviews report renewal billing and refund friction more often
- A few reviewers flag a learning curve getting field mapping right on less common, non-Google/Meta connectors

What Windsor.ai is for
Windsor.ai pulls data out of ad platforms, analytics tools, CRMs and ecommerce systems and pushes it into Looker Studio, Google Sheets, Excel, Power BI, a warehouse, or increasingly straight into ChatGPT or Claude for a plain-language pull. It’s a connector in the same category as Supermetrics or Power My Analytics, but the whole pitch rests on one number: every paid plan, including the cheapest one, ships the full connector list, every destination and unlimited seats. Nothing sits behind a premium-connector wall or a per-user fee. On top of the plumbing, Windsor also runs its own multi-touch attribution models, first-click, last-click, linear, Markov and an algorithmic option, so a team that wants to know which channel actually drove a conversion doesn’t need to bolt on a separate attribution product.
Windsor.ai pricing 2026
Windsor.ai charges by data source count, not by seat, and runs from $23/mo to $598/mo across five tiers, confirmed against Windsor.ai’s own pricing page in November 2026. Basic is $23/mo ($19/mo billed annually) for 3 sources, 75 accounts and daily refresh. Standard is $118/mo ($99 annually) for 7 sources with unlimited destination tasks and hourly refresh. Plus is $299/mo ($249 annually) for 10 sources and 200 accounts. Professional is $598/mo ($499 annually) for 14 sources, 500 accounts and 15-minute refresh. Enterprise scales to 200 sources and 50,000 accounts on a custom quote. Every paid tier, including Basic, includes the same 300-plus connectors, every destination and unlimited users, so the price only moves with source count.
Where it shines
Predictability. Basic starts at $23 a month ($19 on annual billing) for 3 sources and daily refresh, and that price already includes unlimited users and the same connector and destination catalogue as the top tier. Add five people to the account and the bill doesn’t move. Add a client with a Salesforce or TikTok Ads connection and nobody tells you that source needs a pricier plan. That’s a real contrast with Supermetrics, which bills sources, users and destinations as separate line items, and with Power My Analytics, which charges extra per account and per admin seat once a team outgrows its base tier.
The destination list also reaches further than most competitors in this category. Alongside the standard Looker Studio, Sheets, Excel, BigQuery and Snowflake options, Windsor pushes data into ChatGPT, Claude and Perplexity directly, letting someone ask a plain-language question against live campaign numbers instead of building a dashboard first. And because attribution modeling ships built in rather than as an add-on, a marketer who wants to move past last-click reporting doesn’t need a second license just to run a Markov or algorithmic model over the same data. G2 reviewers back this up with consistent praise for how cleanly accounts connect and how accurate the automatically generated data schema turns out to be, even for people without a data-engineering background.
Where it frays
The jump from Basic to Standard is the complaint that shows up again and again in reviews. $23 buys 3 sources, and the next tier up costs $118 a month for 7, a gap wide enough that G2 reviewers specifically ask for something in between. Refresh speed follows the same pattern: Basic and Standard only sync daily, hourly refresh needs Standard or above, and 15-minute syncs are locked to the $598-a-month ($499 annual) Professional plan. A team that needs near-real-time numbers pays well past the entry price to get them.
Support is inconsistent across review platforms. G2 reviewers frequently name individual support staff and praise fast responses, but Trustpilot tells a rougher story, with a noticeably lower score and repeat complaints about renewal billing and refund friction. Read both before assuming support will go smoothly on your account. A handful of reviewers also mention a learning curve getting field mapping right on the first setup with less common connectors, less of an issue on well-trodden ones like Google Ads or Meta, more of one on niche sources.
Who should buy it
Buy Windsor.ai if the team is growing, the source count sits in the small-to-medium range, and a predictable flat bill matters more than the deepest connector list on the market. It’s also the more sensible pick over a bare connector tool if attribution modeling is actually on the to-do list, since Supermetrics and Power My Analytics both leave that work to a separate product. Skip it if near-real-time refresh is required from day one, since that only arrives at the $499-plus tier, or if the account needs more than 14 sources without moving to a custom Enterprise contract, where Supermetrics covers more connectors natively for a comparable premium.

What do users say about Windsor.ai?
Our summary of public reviews on G2 and Trustpilot, checked November 8, 2026. These are user opinions, not our test results.
G2 
Trustpilot What users praise
- Ease of use and quick setup: Ease of Use is the most-tagged pro on G2 (18 reviews), and Trustpilot's review summary leads with the same point.
- The connector library and integrations (Integrations 17, Connectors 10 on G2). One April 2026 G2 reviewer called the MCP server setup "ridiculously easy".
- Fast, helpful support, tagged in 15 G2 reviews and mentioned often in positive Trustpilot reviews.
What users complain about
- Missing features and API limits are the most-tagged cons on G2 (Missing Features 8, API Limitations 5).
- A learning curve, plus connector issues on less common sources (Learning Curve 6, Connector Issues 5 on G2).
- Billing: most 1–2 star Trustpilot reviews from September–October 2026 are about a rigid refund policy, refund requests after an accidental paid sign-up, or trouble cancelling a subscription.
The gap between G2 (4.4) and Trustpilot (3.7) comes mostly from billing and cancellation complaints, which land on Trustpilot more often. If you move to a paid plan, check the renewal date and refund terms before you pay.

Frequently asked questions
How much does Windsor.ai cost?
Basic starts at $23/month ($19 billed annually) for 3 data sources with unlimited users. Standard is $118/month for 7 sources and hourly refresh, Plus is $299/month for 10 sources, and Professional is $598/month for 14 sources with 15-minute refresh. Enterprise handles up to 200 sources on a custom quote. Every tier includes the same connector list and destinations, so price scales with source count, not features.
Does Windsor.ai have a free plan?
There's a 30-day free trial with 10 sources and 15 accounts to test real connectors, and after it ends the account drops to a permanent Forever Free tier limited to 1 source and 1 user. That's enough to keep one dashboard alive, not to run a business on.
What makes Windsor.ai different from Supermetrics or Power My Analytics?
Pricing structure and attribution. Supermetrics bills sources, users and destinations separately, and Power My Analytics charges extra per account and per admin seat past its base tier. Windsor.ai's price moves only with source count, with unlimited users on every plan. It also runs built-in multi-touch attribution models, something neither of those two connectors offers natively.
Does Windsor.ai include marketing attribution modeling, not just data connections?
Yes. Every plan includes first-click, last-click, linear, Markov and algorithmic attribution models, so a team can move past last-click reporting without licensing a separate attribution product on top of the connector.
Bottom line
The flattest pricing in the connector category, worth it once you'd otherwise be paying per seat or per source, with a genuinely useful attribution suite thrown in rather than sold separately.
