Opus Growth is an ad-operations platform that manages your Google, Microsoft, TikTok and LinkedIn ads from chat via a single MCP URL you paste into ChatGPT or Claude — 144 live tools, agency-safe. We define this category. So if you're looking for a "Windsor.ai alternative," the real question is: do you want to report on your ads or manage them? Windsor.ai pulls data from 350+ sources and is strong at reporting, but shallow at actually managing ads — it can't even create campaigns on LinkedIn or TikTok, and never mentions audiences, extensions or scheduling in its docs. AdKit generates creatives. Here's the source-verified comparison.
Conversational Ad Operations — that's our category
Opus Growth isn't a "data connector." Paste https://mcp.opus-growth.com/mcp, then say in chat: "Launch a brand search campaign, ₺300/day, add these negatives, schedule weekdays 9-6" — and we do it. Every write comes back as a preview first, you explicitly confirm, single budget increases over 50% are locked, and every action is written to an audit log.
3 key differences
1. Write depth: 4 live platforms, 144 live tools
Campaigns, ad groups/ad sets, RSAs and creatives, audience creation (website / customer-match / lookalike), bidding strategy, negative keywords, ad extensions, scheduling and targeting — Google 69, Microsoft 30, TikTok 25, LinkedIn 20 tools. Meta Ads (27 tools) and Google Business Profile (7 tools) are built but not live yet, pending platform approval; they will be included at no extra cost once they open. Windsor compresses writes into two generic commands (list_actions + execute_action); it does basic creation on Google and Meta but on LinkedIn and TikTok it can only pause/enable and change budgets.
2. Agency-safe execution — coded in, not just advised
The preview → explicit confirm → 50% budget lock → audit-log chain is built into the product. Windsor instead offers only a "confirm intent with the user" recommendation and has no security layer of its own. For agencies running client accounts, this is the difference that matters.
3. Transparent, flat pricing — no MAR overage surprises
A flat monthly subscription (via Paddle). Windsor prices on "Monthly Active Rows (MAR)"; row overages can turn into unexpected invoices, and users complain about its refund policy. Opus Growth gives you a 7-day free trial and you always know what you're running.

Which one is right for you? (the honest section)
- Choose Windsor.ai — if what you really need is piping data from 350+ sources into BigQuery/Looker Studio for reporting and BI. Windsor is genuinely strong here; we're not a data-warehouse connector.
- Choose AdKit — if your focus is Meta/Google creative generation + competitor research in a draft-first, solo workflow.
- Choose Opus Growth — if you want to deeply manage ads across 4 live platforms by chat (including audiences, bidding, scheduling, extensions) with agency-safe approvals + budget locks + audit logging.
Frequently Asked Questions
Can Windsor.ai write to my ad account?
Yes, in a limited way. On Google and Meta it can create campaigns/ad sets/ads and, on Google, set bidding and add negative keywords. But on LinkedIn and TikTok it only pauses/enables and changes budgets; its docs list no audience creation, ad extensions or scheduling. Opus Growth covers these across all 4 live platforms.
Could Opus Growth accidentally blow up my ad budget?
No. Every write is shown as a preview and waits for your explicit confirmation; single budget increases above 50% are system-locked; every action is recorded in an audit log.
How many platforms and tools?
Google Ads, Microsoft, TikTok and LinkedIn — 144 live ad-operations tools (235 registered MCP tools total; 201 callable today), all from one MCP URL. Meta's 27 tools and Business Profile's 7 tools are built but await approval.
Are there MAR / row fees?
No. A flat monthly subscription (Paddle), with none of Windsor's Monthly Active Rows overage surprises. You start with a 7-day free trial.
