    4. 4Manually find and paste the product landing page content
    5. 5Iterate on the prompt when the output doesn't sound like you

    "Working with HeyNews has been great. Their AI service has saved me a significant amount of time in publishing my daily newsletter. I went from 1 hour per day to 5 minutes per day on creating the content and adding in ads."

    "We've been working with Cagri and the HeyNews team for the past 7 months, and they've helped us land more sponsorships, create ad content, and save us a lot of time on sponsor outreach and coordination. It's helped us grow sponsorship revenue without adding more work on our side."

    Frequently asked questions

    How is this different from using ChatGPT?+
    ChatGPT doesn't know how you write. Every time you use it, you're building a prompt from scratch, pasting examples, explaining what tone you want, then doing it all again next week. We spent over a year building three specialized AI pipelines: one that learns your newsletter voice, one that breaks down the sponsor's copy and landing page, and one that rewrites the ad in your style. AdApt saves your voice profile and reuses it across every future ad, with format-specific output for primary ads, quick spots, and dedicated emails.
    Will the ads actually sound like my newsletter?+
    That's what it's built for. The AI reads your newsletter and picks up on how you write, not just what words you use. It rewrites the ad from scratch in your voice. If something feels off, you can tweak the tone and regenerate with one click.
    What newsletter platforms does it work with?+
    Any platform with a public URL. Substack, beehiiv, Kit, Ghost, Mailchimp, whatever you use. Paste the link and we pull the content. You can also paste text directly if your posts aren't public.
    Is my newsletter content stored or shared?+
    No. Your content is used to analyze your writing style and nothing else. We don't share it, and we don't use it to train models. Saved voice profiles stay in your account for reuse, but the original text is never exposed.
    Do I need a credit card to get started?+
    Every plan starts with a 14-day free trial that includes 1 adaptation credit. Your subscription starts automatically when the trial ends. Cancel anytime before day 14 and you won't be charged.
    Can I use it for multiple newsletters?+
    Yes. Save a separate voice profile for each one. Pro supports up to 5, Publisher supports up to 10. Batch mode lets you adapt one ad across all your saved newsletters in a single action.
    What if the sponsor gave me a script I have to follow?+
    Paste it in. AdApt keeps the sponsor's messages, links, and CTAs intact, it only changes the delivery. The requirements stay, the robotic tone goes.
    How many ads can I adapt per month?+
    Free gets 1 adaptation. Pro gets 40/month, Publisher gets 120/month. Primary and secondary ads cost 1 credit each. Dedicated emails cost 3.
    What if the output doesn't match my voice perfectly?+
    Flag the specific part that sounds off and tell us why (too formal, wrong vocabulary, etc.). AdApt stores your feedback and uses it to avoid the same mistakes next time. You can also save tone presets (like "shorter + wittier") and apply them automatically to every new adaptation.
