Secrets AI vs Nastia AI: One Remembers You, One Is Cheap

Verdict at a glance

Secrets AI is the more complete companion. It has tiered memory with Lorebooks, live voice calls, realistic images, adult video and per-chat content controls. It also costs $19.99 a month to start, and the features people actually want, like group chats and personas, sit behind a $39.99 tier.

Nastia AI is the budget pick. $11.99 a month, $15.99 for Unlimited, and group chats with up to ten companions. It is built for talk-first uncensored roleplay, not for remembering your birthday three weeks later. Reviewers report memory dropping off within days.

We rate Secrets AI 9.9 out of 10. This comparison rests on published pricing pages, policies and user reports. Nobody here spent weeks chatting on both platforms, and we are not going to pretend otherwise.

Quick answer

If you want one companion who stays consistent, call you on the phone and send a photo that does not look like a painting, pick Secrets AI. Budget for $19.99 a month and expect to be upsold on credits.

If you want to flirt cheaply, run several characters at once and do not care whether the bot forgets last Tuesday, pick Nastia AI. Put the important details in the backstory, because the chat history will not hold them.

What each platform is actually for

Secrets AI is run by Secret Labs Inc., adults-only, aimed at US and Canada. The product is built around continuity: chat models with different capability tiers, Lorebooks for lore, Time Travel to rewind and branch scenes, proactive messages, and live calls in over 70 languages. It reads like a platform for people who want a relationship that accumulates.

Nastia AI is run by Nastia Cybernetics, a French company. The pitch is lighter: pick a character, pick a sin-based personality, flirt. Group chats hold up to ten companions on paid plans, backstories run up to 2,000 characters, and Unlimited lists 4K selfies, 1080p video and custom voice cloning. It is a flirting toy with a big cast, not a memory machine.

Filters and NSFW policy

Secrets AI handles adult content with a setting rather than a blanket ban. Each chat gets a Spice Level: Mild, Medium or Spicy. That is cleaner than most competitors, because you are not guessing whether a scene will trip a filter halfway through.

Nastia AI is uncensored by default and leans on written rules instead. Its terms ban minors, aged-up characters, non-consent and impersonation. In one test, free-tier NSFW content was absent, which suggests the experience varies by signup date. Do not assume the free plan behaves like the paid one.

Both platforms are adults-only. Neither is a place for anything involving real people without consent, and Nastia's terms say so explicitly.

Memory: the real split

This is where the two stop being comparable.

Secrets AI tiers its memory by plan. Free users get basic memory that fades sooner. Paid plans hold context across sessions, per the platform's wiki and most reviews, and Lorebooks let you pin facts you want kept. You can also rewind a scene with Time Travel instead of restarting the whole conversation.

Nastia AI advertises persistent memory. Reviewers put the practical limit around 50-plus messages, or up to two weeks. One documented test had a detail survive day four and vanish by day seven. That is not a bug you can argue your way around. It is the design.

Practical rule for Nastia: anything the bot must remember goes in the backstory, not the chat. Treat the chat window as disposable.

If long-term continuity is the reason you are paying, Secrets wins and it is not close. If you reset the scene every few days anyway, the gap costs you nothing.

Media and voice

Secrets AI has the deeper media stack. Images cost 50 credits, 2K images 100 credits, adult video 600 credits. Calls run 50 credits per minute. Text-to-speech is 10 credits per 100 characters. Live voice calls are the feature Nastia does not match. Secrets also does not accept user photo uploads, which limits how personal a character can look but removes a privacy headache.

Nastia AI covers images, selfies and short video on Unlimited, with reference photos. Reviewers report roughly 10 tokens per image, 30 to 60 seconds per generation, and voice messages at about one token each. Custom voice cloning is listed on Unlimited. What we could not find is live voice calls. Nastia gives you recorded voice notes; Secrets gives you a conversation.

Neither platform offers a live avatar doing voice and video calls in the way Kindroid does. If that is the bar, neither one clears it.

Character creation and group chats

Secrets AI gives you one custom character free, then charges 500 credits per extra. Group chats hold two to three companions and are Ultimate-only. Personas and proactive messages are also Ultimate features. Lorebooks are for Premium and Ultimate. The feature list is generous, but it is gated in layers, so read the plan before you build a cast.

Nastia AI lets group chats run up to ten companions on paid plans. Backstories go to 2,000 characters, and personality traits are built around the seven deadly sins. For a cheap, chaotic group scene, Nastia is the better fit. For a small, well-remembered group with lore attached, Secrets is the better fit, provided you pay for Ultimate.

Pricing and credits

Numbers from the pricing pages, not from memory.

Plan	Secrets AI	Nastia AI
Free	$0: 20 daily messages, basic memory, media locked	Free with daily token limits, no card
Entry paid	Premium $19.99/month	$11.99/month (contents not described)
Multi-month	$49.99 for 3 months; $89.99 for 6 months	Annual billing reported by reviewers
Annual	$109.99/year (about $9.17/month)	Reported $87.95 Basic, $99.95 Unlimited
Top tier	Ultimate $39.99 monthly, $319.99 yearly	Unlimited $15.99/month
Media currency	Moments: 8,000 Premium, 15,000 Ultimate	Tokens; 3,000 bonus reported on Unlimited

Secrets Premium includes 8,000 Moments a month, roughly 160 images. Ultimate includes 15,000. Moments do not roll over, so unused credits evaporate. Failed generations are refunded automatically, which is the least they can do.

Model access is tiered too. The free plan includes the S3 and X-3 chat models. S5 opens from Premium up. S4 is Ultimate only. If a review quotes a model name without saying which plan, it is telling you nothing.

Nastia's entry price is real and lower. The catch is that the $11.99 plan's contents are not described in the same detail as the Unlimited plan, and plan names shift between pages and third-party reviews. An older $6.69 listing still floats around. Treat unverified prices as provisional.

The annual gap narrows fast. Secrets at $109.99 a year is about $9.17 a month, cheaper than Nastia's monthly Unlimited. If you are staying a year, the price argument gets weaker.

Free tier

Secrets AI gives 20 messages a day, capped at 500 characters each, with media locked and basic memory. Enough to judge tone. Not enough to judge memory, because the free tier is where memory is weakest.

Nastia AI gives daily token limits with no card required. Reviewers describe the free-plan wording as contradictory, so read the plan page yourself rather than trusting a summary. Neither free tier tells you much about the paid experience. Test the same character on both, then decide.

Privacy and safety

Read this part twice.

Topic	Secrets AI	Nastia AI
Company	Secret Labs Inc. (US/Canada)	Nastia Cybernetics (France)
Encryption	AES-256 at rest and transit; not end-to-end	In transit only
Training	Policy allows model training	Not explicit; used to improve replies
Voice data	Call audio deleted; transcript kept	Voice samples collected
Selling data	Card numbers not stored (PCI processors)	Says it never sells data
Deletion	Chat history immediate; 7-year transaction records	Immediate after cancel; violation records up to 7 years
Refunds	Non-refundable except law; EU/UK 14-day right	Generally non-refundable; auto-renews

Secrets AI has the stronger storage story: AES-256 at rest and in transit, and call audio is deleted after the call, though the transcript stays. But its homepage has claimed end-to-end encryption, and its own policy only covers at-rest and transit. That is not end-to-end. The policy also allows using data for model training. Its wiki does not confirm the email-free signup claim, so do not count on it.

Nastia AI encrypts in transit only, which is thinner. It says it never sells data, and it uses a third-party age confirmation provider. Its vendors include US-based hosting, AI, payment, analytics and advertising providers, so data crosses borders. Deletion is immediate after cancel, and you must cancel before deleting your account or you will keep paying.

Age gates differ. Secrets uses self-attestation and may demand verification. Nastia uses a third-party provider. Neither is a guarantee.

Basic hygiene applies to both. Use a spare email. Do not put your legal name, address or real photos in a chat. Keep fantasies fictional.

Watch outs

• Secrets real cost. The useful features (groups, personas, proactive messages, S4) need the $39.99 tier. Premium looks like the product and behaves like a demo.
• Secrets video burns credits. 600 credits a clip against 8,000 monthly Moments disappears fast. Payments are generally non-refundable.
• Secrets complexity. Many models, credit types and settings. Expect a confusing first week.
• Nastia memory fades. Days, not weeks. Plan around it.
• Nastia free-plan wording. Contradictory between pages. Verify before paying.
• Nastia media trails. No live calls found, and images and clips sit behind the category leaders.
• Nastia plan names change between pages and reviews. Confirm what you are buying at checkout.
• Both are browser-based. Installable web apps, no official store apps.

Who should pick which

Pick Secrets AI if you want one companion who remembers, a voice you can actually call, realistic images and fine control over how explicit a chat gets. You are willing to pay $19.99 a month, or $109.99 a year, and you will not be shocked by a $39.99 upgrade.

Pick Nastia AI if you want cheap uncensored flirting, a large cast and group scenes with up to ten characters. You do not need live calls. You are fine re-stating the plot every few days. $11.99 a month is the honest price, and $15.99 Unlimited is still under Secrets' entry tier.

Skip both if you need a live avatar doing voice and video calls. Skip Nastia if memory is the point. Skip Secrets if $20 a month is already your ceiling.

Alternatives

Neither platform is the last word. Prices below are as reported; treat unverified ones as provisional.

Alternative	Best match for	Pricing (as reported)
Candy AI	Photorealistic images, visual builder	$13.99/month or $3.99/month yearly
Nomi	Long-term memory	$15.99/month
Kindroid	Memory, calls, live video	$15.99/month (App Store)
GoLove AI	Voice and in-chat photos	About $4.15/month per one guide; our data $9.99
CraveU AI	Budget pricing	From $4.99/month annual (reported)
Muah AI	Cheap annual VIP	About $5.83/month ($69.99/year)
Botify AI	Mobile app, casual roleplay	$19.99/month (reported)

Nomi claims a three-layer memory by its own description, and Kindroid claims five layers plus live avatar calls at $15.99. For pictures, Candy AI undercuts both on annual billing at $3.99 a month, though its memory is thin. Our Candy.ai review covers the token bills. If you want a shortlist by use case, start with the best AI companion app for your use case.

One caution on cheap annual plans: a 2024 breach at Muah exposed user emails and prompts. Low price is not the same as low risk. And Nomi does not allow nude images, which rules it out for some buyers regardless of memory.

Bottom line

Secrets AI is the fuller product and it charges like one. Better memory, live calls, stronger storage encryption, real adult video. It also gates the good features behind its top tier and does not refund.

Nastia AI is the cheaper fling. Unbeatable on price for group scenes and uncensored talk, weak on memory, thin on encryption, no live calls.

Test both free tiers with the same character before either gets your card. Then pay monthly, at least once, before you commit to a year.
