Pricing notesFree tier available. Paid from $5.99/month for full access.Plans are now monthly-only, starting around $17.99/mo (unlimited messages plus a set image/voice allowance) and scaling up through mid tiers to roughly $49.99/mo for unlimited images and voice plus video-generation coins. Cryptocurrency accepted. Coins/credits available for one-off feature purchases including video.

My take

If you want to try before you pay, Kupid.ai lets you: Caveduck asks for a card first. A free tier is a sampler, not a plan, but it tells you whether the chat suits you before money moves. Caveduck is the cheaper way in at $5.99/mo against $17.99/mo for Kupid.ai. The entry price is only part of it: image, voice and video are often metered on top, so the pricing notes row matters as much as the headline. Kupid.ai simply does more: nsfw content, image generation and voice messages are on its list and not on Caveduck's. More features is only better if you will use them.

The better value in each row is marked in green. Search visits and brand searches are DataForSEO estimates; Tranco and Chrome UX tiers are ranks, not visit counts.

My take

Start with the row this site ranks on. When someone types "ai girlfriend" into Google in the US, Kupid.ai is there at #7; Caveduck does not appear in the tracked positions at all. That is why Kupid.ai sits higher here even if it is the smaller site: it is the one the category sends newcomers to. On size, Kupid.ai is the busier site: 131,142 search visits a month worldwide, about half as much again what Caveduck gets (100,008). These are estimates of visits from Google only, so a site with apps or ads can be bigger than this shows. Brand searches are the loyalty line: 18,100 people a month type Caveduck's name, against 5,400 for Kupid.ai. A name people type on purpose is a site they come back to; a site with lots of visits and few brand searches is living on rankings it could lose. Tranco tells a slightly different story: it counts every visit, not only search, and there Caveduck comes out ahead (#56,089 against #254,630). When search and all-traffic disagree, the site that wins on Tranco has an audience that does not come through Google. Kupid.ai's Domain Rating of 73 against 43 means far more sites link to it, which is what keeps rankings stable; the weaker link profile is the one more likely to move, up or down, when Google reshuffles. In plain terms: Kupid.ai is both the bigger site and the one the category search points to.

“Users” is the balance of the YouTube reviews, Reddit threads and articles read for each brand page; “my test” is whether my own month on the site agreed with them.

My take

Users rate them about the same: 4 of 10 features positive for Caveduck and 3 of 10 features positive for Kupid.ai. My own month did not always match the crowd: I disagreed with users on 2 points for Caveduck and 2 points for Kupid.ai, and each disagreement is spelled out on the brand page.
