Not forUsers requiring a native mobile app, free trial access, real-time video calls, or an affiliate programThose who need reliable live voice calling or responsive customer support
OperatorNot disclosed on the site or in any source I read; support runs through support@nextpart.ai and a Discord, and the domain was registered through Namecheap in December 2023Vilala Limited
Pricing notesMonthly: $9.99, $19.99. Yearly: $83.88, $155.88. Confirmed still accurate. Crypto accepted. No free tier. The top Deluxe tier now also includes a beta character video generation feature.1 Month: $19.95. 12 Months: $79.80 (~$6.65/mo). Token purchases and cryptocurrency payments accepted.

My take

If you want to try before you pay, HeraHaven lets you: NextPart AI 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. NextPart AI is the cheaper way in at $9.99/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. On adult content they are not the same product: NextPart AI 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, more than 35 times what NextPart AI gets (3,503). 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: 5,400 people a month type HeraHaven's name, against 880 for NextPart 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. NextPart AI 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: 3 of 10 features positive for NextPart AI and 3 of 10 features positive for HeraHaven. Where they split, NextPart AI gets the better word on memory. My own month did not always match the crowd: I disagreed with users on 5 points for NextPart AI and 2 points for HeraHaven, and each disagreement is spelled out on the brand page.

My verdict on each

NextPart AI logo

NextPart AI

#51 on the ranking

Nextpart is a credit-metered NSFW roleplay platform that sells memory by the tier, and that idea is better than its reputation, which is almost nonexistent.

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.
