Secrets AI vs Nastia AI: Memory, Calls and What You Actually Pay

Two apps, two very different sales pitches. Secrets AI wants to be the companion you keep for months: tiered memory, live voice calls, photorealistic images, adult video. Nastia AI wants to be the one you open for twenty minutes of uncensored flirting without thinking hard about the bill.

Neither pitch is wrong. But the price gap is bigger than it looks, and the plan names on both sides shift depending on which page you read. Here is the whole comparison, drawn from pricing pages, terms of service, privacy policies and what users report — not from a weeks-long test with paid accounts, because we don't run those.

Verdict at a glance

Secrets AI is the more complete product. Better memory, real live calls, stronger media, sturdier encryption. It also costs more at every tier and burns credits fast on video.

Nastia AI is the budget pick. Cheaper entry, cheaper ceiling, group chats for up to 10 companions, uncensored by default. Its memory fades after several days, there are no live calls, and its privacy policy is thinner.

Quick answer

If you want one companion who remembers your job, your ex and the name of your dog three weeks from now, and you want to hear her voice, pay for Secrets AI. We rate it 9.9 out of 10.

If you want cheap, fast, uncensored chat and you don't care whether the bot recalls last Tuesday, Nastia AI is the smarter buy. It scores 9.4 out of 10.

If you are on the fence, spend a week on both free tiers with the same character premise. You'll know which one annoys you less by day three.

What each platform is actually optimizing for

Secrets AI is built around continuity. The memory system is the product; the images and calls are the rewards for paying. Everything from the chat model lineup (S3 and X-3 on every plan, S5 from Premium, S4 on Ultimate) to the Lorebooks feature points at keeping a long thread coherent.

Nastia AI is built around speed and volume. Eleven-dollar entry, uncensored by default, character traits themed on the seven deadly sins, realistic or anime art styles, up to 2,000 characters of backstory. It reads like a product designed for people who want to start a new chat every night, not maintain one.

That difference explains almost every other difference below.

Filters, NSFW policy and age checks

Both are adults-only (18+) products. Both ban minors in terms, and both explicitly ban aged-up depictions — the "she's 18, honest" loophole. Nastia's terms also ban non-consent content and impersonating real people.

Secrets AI gives you a per-chat Spice Level dial with three settings: Mild, Medium, Spicy. That is a content control, not a filter you fight. AI-assisted moderation watches for underage signals. Age verification is self-attestation at signup, though the company reserves the right to demand extra verification later.

Nastia AI runs its age check through a third-party provider. It is uncensored by default within the rules above, which is the honest way to describe it: the rules are narrow and specific, not vague.

One practical note: Secrets AI is a US/Canada company (Secret Labs Inc.). Nastia AI is French (Nastia Cybernetics). If jurisdiction matters to you, that is the fork in the road.

Memory: the real dividing line

This is where the two products stop being comparable.

Secrets AI runs a tiered memory system. On paid plans, memory persists between sessions — the bot doesn't wake up blank. Premium and Ultimate add Lorebooks: a cast list, a world bible, relationship notes, fixed facts, and a chronicle of what has happened. You can pin the things that matter instead of hoping the model dredges them up. The free tier gets basic memory that fades.

Nastia AI advertises persistent memory. Reviewers put the working window at 50-plus messages, with recall reported up to about two weeks. In one reported test, detail was gone by day seven. That's the gap in plain terms: broad strokes survive, specifics don't.

The workaround is to put key facts in the backstory — you get up to 2,000 characters — rather than trusting chat history. Treat the backstory as the memory and the chat as disposable. It works. It is also manual labor Secrets AI does for you.

Media and voice

Secrets AI: images cost 50 credits, or 100 at 2K resolution. Failed generations are refunded, which is the right policy and rarer than it should be. Premium includes 8,000 Moments a month — roughly 160 images. Ultimate bumps that to 15,000. Adult video runs 600 credits a pop, so video is a treat, not a habit. Live voice calls cost 50 credits a minute and support 70-plus languages; text-to-speech runs 10 credits per 100 characters. Call audio isn't stored, but a transcript is kept so the bot remembers the conversation.

Nastia AI: images cost 10 tokens each and take 30 to 60 seconds, with reference photos supported. The Unlimited plan lists 4K selfies and 1080p video. Voice messages reportedly cost one token per message. Unlimited also includes custom voice cloning. What Nastia does not have, as far as anyone has documented, is live calls. Recorded notes and cloned voices, yes. A real-time conversation, no.

If you want to hear a voice answer you in the moment, that's Secrets AI or nothing in this pair.

Character creation and group chats

Secrets AI: your first custom character is free, each extra one costs 500 credits. Personas, personality editing and proactive messages — the bot messaging you first — are Ultimate-only. Group chats are capped at 2-3 companions and also require Ultimate.

Nastia AI: backstories up to 2,000 characters, traits built on the seven deadly sins, realistic and anime art styles. Group chats support up to 10 companions on paid plans. Ten is a lot. It is also Nastia's clearest structural win — if you want a chaotic ensemble, Secrets AI will not give it to you at any price.

Pricing and credits

Secrets AI charges more and structures it around credits. Nastia AI charges less and structures it around tokens. Both currencies expire monthly on Secrets' side — Moments do not roll over.

Plan	Secrets AI	Nastia AI
Free	$0: 20 daily messages, media locked	Daily token limits, no card
Entry paid	Premium $19.99/mo	$11.99/mo
Multi-month	$49.99 3mo; $89.99 6mo	Annual billing reported
Annual	$109.99/yr (~$9.17/mo)	$87.95 Basic; $99.95 Unlimited reported
Top tier	Ultimate $39.99/mo, $319.99/yr	Unlimited $15.99/mo
Media currency	8,000 Moments Premium; 15,000 Ultimate	Tokens; 3,000 bonus on Unlimited reported

Three things the table doesn't show.

First, Secrets AI's annual price of $109.99 works out to about $9.17 a month. That undercuts Nastia's monthly rate, though not its annual. If you're certain you'll stay a year, the gap narrows sharply.

Second, Secrets AI's Ultimate tier at $39.99 a month is not a vanity upgrade. Groups and proactive messages live there. If those features are the reason you signed up, $19.99 doesn't get you them.

Third, Nastia's pricing is genuinely messy. Plan names change between pages and reviews. An older third-party listing shows a $6.69 ladder that doesn't match current pages. Treat any Nastia price you see quoted outside its own checkout as provisional.

Free tiers

Secrets AI free: 20 daily messages, basic memory, media locked, 500-character message cap, S3 and X-3 models available. That's a real trial, not a teaser, but the character cap makes long roleplay awkward.

Nastia AI free: daily token limits, no card required. The wording on what the free plan includes is contradictory in places, which is worth knowing before you build expectations around it.

Both free tiers are enough to test whether the conversation style clicks. Neither is enough to judge memory.

Privacy and safety

This is the section most comparison articles skip. Don't.

Topic	Secrets AI	Nastia AI
Company	Secret Labs Inc. (US/Canada)	Nastia Cybernetics (France)
Encryption	AES-256 at rest and transit; not E2E	In transit only
Training	Policy allows training	Not explicit; used to improve replies
Voice data	Call audio deleted; transcript kept	Voice samples collected
Selling data	Card numbers not stored	Says never sells data
Deletion	Chats immediate; 7-yr transaction records	Immediate after cancel; violations up to 7 yrs
Refunds	Non-refundable except law; EU/UK 14-day	Generally non-refundable; auto-renews

The headline: neither platform offers end-to-end encryption. Secrets AI's homepage has claimed E2E at points, but the privacy policy covers encryption at rest and in transit only. That's still stronger than Nastia, whose policy describes encryption in transit only. AES-256 at rest means a database breach exposes less. It does not mean the company can't read your chats, because it can, and its policy permits using data for model training.

Nastia says it never sells data, shares some data with vendors including US-based ones, and collects voice samples if you use cloning. Its deletion is immediate once you cancel — but you must cancel the subscription before deleting the account, or you'll keep getting billed for an account that no longer exists.

Secrets AI deletes chat history immediately but keeps transaction records for seven years, which is accounting, not surveillance. Card numbers aren't stored. Payments are non-refundable except where law requires; EU and UK users get the 14-day right.

Nastia bills generally non-refundable and auto-renews. Set a calendar reminder.

The catch on each

Secrets AI: the real cost is $19.99 a month, and the features people talk about most — groups, personas, proactive messages — need the $39.99 tier. Video at 600 credits per generation drains a monthly allowance quickly. Payments are generally non-refundable. And the model lineup plus settings can feel like a cockpit on day one.

Nastia AI: memory fades after several days. No live calls. Images and clips trail the leaders in quality. Free-plan wording contradicts itself. Plan names shift between pages. You must cancel before deleting.

Neither has an official App Store or Google Play app. Both run in the browser plus an installable web app. Any "official app" listing you find is fake; don't install it.

Who should pick which

Pick Secrets AI if: you want one companion over months, you care about call audio and realistic images, you'll use the Spice Level dial rather than fight a filter, and $19.99 a month — or $109.99 a year — is acceptable for that. Read the Secrets AI review first; the tier structure matters more than the marketing.

Pick Nastia AI if: you want cheap uncensored flirting, you like building characters with long backstories, you want group scenes with more than three companions, and you'll accept that the bot forgets specifics. Put the facts you care about in the backstory.

Pick neither if: you need end-to-end encryption. Nobody in this category offers it.

Alternatives worth a look

Prices below are reported figures from vendor pages and user accounts, not verified at checkout. Treat them as provisional.

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

A few specifics. Candy.ai is the image play — our Candy.ai review covers where the token bills land. Nomi has a three-layer memory system by its own description and does not allow nude images. Kindroid claims five-layer memory plus live avatar calls. OurDream AI has strong media but fuzzy privacy, as our OurDream AI review explains. Muah AI is cheap annually, but a 2024 breach exposed emails and prompts, so weigh that against the $69.99.

One more on Nastia's side: few monthly plans undercut its $15.99 Unlimited. Yearly, Candy AI at $3.99 a month and Muah at roughly $5.83 are the real budget plays.

Bottom line

Secrets AI is the more complete companion. If memory and voice are what you're buying, it's the one. Nastia AI is the better value if you're buying chat volume, group scenes and a low monthly number. Test both free tiers with the same character premise before you pay either of them, and cancel Nastia before you delete your account.
