My take

If you want to try before you pay, HeraHaven 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 $19.95/mo for HeraHaven. 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. HeraHaven simply does more: immersive ai chat with memory, nsfw capability and image generation are on its list and not on Caveduck's. More features is only better if you will use them. On adult content they are not the same product: Caveduck allows it on paid plans, HeraHaven keeps a filter. Decide that first and half the comparison decides itself.

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

None of these ranks in the tracked positions for "ai girlfriend", so their places on this site come from all-traffic rank, and their visitors arrive by name, by ads or from app stores rather than from the category search. On size, HeraHaven is the busier site: 118,642 search visits a month worldwide, about the same as 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 HeraHaven. 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 #405,892). When search and all-traffic disagree, the site that wins on Tranco has an audience that does not come through Google. Caveduck is the older domain (2023 against 2024), which counts for something in a category where sites close without notice.

“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 HeraHaven. Where they split, Caveduck gets the better word on chat and roleplay. HeraHaven gets it on image generation. My own month did not always match the crowd: I disagreed with users on 2 points for Caveduck and 2 points for HeraHaven, and each disagreement is spelled out on the brand page.

My verdict on each

HeraHaven

#42 on the ranking

HeraHaven makes the best images at the lowest annual price of any companion I have tested, and after a month with it I would still hesitate to recommend the company behind them.
