Copy.ai

Copy.ai began as an AI copywriting tool and has repositioned itself as a go-to-market AI platform, automating sales and marketing workflows rather than just producing text. It was founded in 2020 by Paul Yacoubian and Chris Lu and operates as a remote-first company out of the United States.

There is a free plan with a monthly word allowance, and paid tiers start at around $49 per month. Workflow and enterprise plans sit above that and are priced on request, targeting revenue teams rather than individual writers.

The affiliate program is one of the most generous in the AI writing category, paying 45% commission on referred subscriptions. Sources disagree on whether that runs for 12 months or genuinely for the lifetime of the customer, so confirm the current term in the affiliate dashboard before you build a campaign around it.

The cookie window is 60 days from the last click, payouts are monthly via PayPal, and there is no minimum payout threshold — unusual in this category, and helpful if you are starting from a small audience.
