Evernote used ChatGPT Ads to reach people who work with AI and tracked new users from their first ad click through a free trial to a first paid subscription.
The company’s goal was to demonstrate practical value to new users: how notes, conversations and transcriptions can be organized and later retrieved — in other words, how Evernote can act as a "second brain." Many potential users already know the Evernote name, so the challenge was to present the product’s evolution and AI capabilities in a way that feels relevant to current workflows.
Campaign setup and measurement
Evernote translated high-performing messaging from search campaigns — emphasizing saving and organizing notes and transcriptions — into ChatGPT Ads. Those ads directed people to Evernote’s website, including the homepage, and the campaigns were optimized for new account registrations.
Performance was measured using Evernote’s first-party web analytics and subscription records. Evernote attributed a new account to ChatGPT Ads when the user’s first tagged visit came from a ChatGPT ad click.
Early results: registrations and trial-to-paid conversion
In the first month, Evernote’s core ChatGPT Ads campaigns produced an early signal of interest: roughly 25% of desktop visits from those campaigns resulted in a new Evernote account (desktop registration). These desktop visits and registrations were measured for September 14–28, 2026.
More important to Evernote’s subscription business was the conversion from free trial to paid subscription. Trials that originated from the featured ChatGPT Ads campaigns (trial starts dated August 28–September 12, 2026) converted to paid subscriptions at a rate approximately 10–20% higher than Evernote’s historical paid-acquisition benchmark covering March–August 2026. Evernote notes that this comparison does not establish incremental lift but provides an early performance signal.
Why this matters
A higher trial-to-paid conversion rate suggests the ChatGPT environment helped reach users who found tangible value in Evernote and were willing to pay for it. For Evernote, higher-quality acquisition — not just higher volume — is important because it can translate into more sustainable subscription growth.
Next steps
Evernote views the first-month results as encouraging and directional while it tests whether the channel’s performance holds up at scale. The company plans to make the link between its product and AI workflows more concrete by exploring additional use cases and creating tailored creative and landing pages that show how Evernote can be integrated into people’s day-to-day work.
