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.

I bought a membership on both and tested each for a month. What they offer, their measured numbers and what their users say, next to each other, with my verdict on each at the end.
The scoreboard
NextPart AI leads on 2 of the 4 figures that decide most choices.
In short
| What they offer | ||
|---|---|---|
| Free tier | No | No |
| Entry paid plan | $9.99/mo | $5.99/mo |
| Adult content | Allowed on paid plans | Allowed on paid plans |
| Features |
|
|
| Best for | Users wanting balanced anime/realistic designs, voice messaging, privacy-friendly crypto payments, and competitive pricing | Users seeking NSFW chat, images, and seductive voice messages with custom companions and browser-based fantasy |
| Not for | Users requiring a native mobile app, free trial access, real-time video calls, or an affiliate program | Those needing calling/video, preferring mobile apps, wanting free trials, or using cryptocurrency |
| Operator | Not 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 2023 | Not disclosed on the site or in anything I read; the footer gives social links and no company name |
| Pricing notes | Monthly: $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. | Monthly: $12.99. Yearly: $71.88 ($5.99/mo). No free tier. No crypto. Affiliate program available. |
My take
Neither has a real free tier, so you are choosing on price and features from the start. Fanfinity is the cheaper way in at $5.99/mo against $9.99/mo for NextPart 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.

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, NextPart AI is the busier site: 3,503 search visits a month worldwide, about 5 times what Fanfinity gets (729). 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: 1,000 people a month type Fanfinity'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's Domain Rating of 38 against 14 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. NextPart AI is the older domain (2023 against 2025), 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 Fanfinity. Where they split, NextPart AI gets the better word on memory and characters and customisation. Fanfinity gets it on chat and roleplay. Both get the same complaint on free tier, so that is a category problem rather than a reason to pick one over the other. My own month did not always match the crowd: I disagreed with users on 5 points for NextPart AI and 4 points for Fanfinity, and each disagreement is spelled out on the brand page.
