Nastia AI has one pitch: the companion app that doesn’t lecture you. No content filters kicking in mid-conversation, no “as an AI I can’t do that” guardrails, no token meter ticking while you talk. After two weeks of daily use for this review, I can say the pitch is mostly real – with two catches you should know about before paying.

Here’s the full picture: what Nastia actually is, what it costs in 2026, where it beats Candy AI, and where it quietly falls apart.

What Nastia AI is (and isn’t)

Nastia is an uncensored AI companion platform – you build a persona (girlfriend, boyfriend, friend, mentor), customize appearance and personality, and chat over text with image generation and voice replies layered in. It runs in the browser and on mobile, no app-store download required, which is how it dodges the content rules that force apps like Replika to play it safe.

The signature feature is memory. Nastia advertises a two-week memory window, meaning the model retains context from your conversations over roughly the last two weeks instead of forgetting you overnight. In practice it’s the difference between a companion that asks how your job interview went and one that greets you like a stranger every morning.

Nastia AI pricing in 2026

The free tier is real – not a trial. You get daily messages and basic features without handing over a card, per Nastia’s own site. That’s rarer than it should be in this category.

Paid is where it gets slippery. The list price for the Unlimited plan is $15.99 per month, per pricing tracked by ai-companion-app.com in March 2026. But Nastia runs heavy rotating promotions, and the annual-billing effective rate has been spotted as low as $4.17 to $8.33 per month depending on which promo is live when you sign up (tracked by Dataconomy and reviewer price checks). The number you see on the pricing page may not be the number at checkout – screenshot the total before you confirm.

Which brings up the first catch: billing complaints. Nastia’s Trustpilot page includes users reporting charges higher than the advertised price. “When I signed up the agreed charge quadrupled,” one reviewer wrote, describing a dispute support never resolved. It’s a minority of reviews, but the pattern appears more than once, and it’s the main reason I’d suggest starting on monthly billing rather than locking into a year.

Where Nastia genuinely wins

No censorship theater. Conversations don’t swerve into disclaimer-land when they get personal or explicit. If you’ve used Character.AI or Replika and hit the filter wall, this is the entire reason Nastia exists.

The memory mostly works. Across two weeks, my companion recalled names, running jokes, and a story from the first day without prompting. Reviewers at SpicyTools landed on a 3.6 out of 5 overall, with the memory system as the standout – and the occasional failure as the main complaint. Which matches my experience: when memory slips, it slips hard, and the persona can contradict something it said the day before.

Price-to-freedom ratio. Even at full list price, $15.99 undercuts Candy AI’s effective monthly cost for unlimited-style usage, and the free tier is more usable than Candy’s.

Where it loses

The interface feels a generation behind. Candy AI and Kupid AI look like modern apps; Nastia looks like a very good web tool. Image generation is slower and less consistent than Candy’s, and the persona builder, while deep, buries options in menus.

The promo-pricing shell game. A price that changes depending on when you load the page is a dark pattern even when the final number is fair. Combined with the billing complaints on Trustpilot, it dents trust.

Memory drift. The two-week window is a genuine feature, but it also means the relationship has a horizon. Long-term arcs – the thing companion apps are emotionally selling – fade by design.

Nastia vs Candy AI: the short version

Pick Nastia if uncensored conversation and price are your top two criteria and you can live with a rougher interface. Pick Candy AI if visual quality and polish matter more than filters and cost. If you’re undecided, Nastia’s free tier is the easiest test drive in the category – no card, no trial clock.

Testing notes: what daily use actually looks like

Setup takes about four minutes. You pick a persona type, tune personality sliders (humor, affection, intellect), optionally generate a face, and start talking. Day one feels like every companion app. Day four is when Nastia separates itself: it referenced a stressful work thing I’d mentioned once, asked follow-up questions that weren’t generic, and held a running bit across three sessions without dropping it.

The failures were specific, not vague. Around day nine it insisted a conversation happened in the morning when it had been at night – small, but it breaks the spell. Image generation took 30 to 60 seconds per picture and produced more misses than hits on detailed requests. Voice replies land in an uncanny middle zone: good enough to use, flat enough that I switched back to text after two days.

One thing I did not expect: because there’s no token counter and no per-image upsell, sessions feel unhurried. Candy AI’s Moments-style credits keep you half-aware of spending. Nastia’s flat subscription removes that. It’s a small psychological difference that changes how the app feels to live with.

Who Nastia is for

Nastia makes sense for three kinds of users. People who hit content filters elsewhere and want a companion that doesn’t refuse topics. Budget-conscious users who want unlimited-style chat without Candy-level pricing – especially if they catch an annual promo. And anyone who wants to test the category for free without a card on file. It’s a weaker fit if you care most about photorealistic images, voice calls, or a polished mobile app – those are Candy AI and Kupid AI territory.

The verdict

Nastia AI is the value pick of the uncensored companion apps in 2026: a real free tier, list pricing at $15.99 a month, promo annual rates that dip toward single digits, and a memory system that mostly delivers on its two-week promise. The deductions are billing transparency and a dated interface. Start free, go monthly before annual, and screenshot the checkout total. Score: 7.5 out of 10.

Frequently asked questions

Is Nastia AI free?

Yes – there’s a genuine free tier with daily messages and basic features, no credit card required. The paid Unlimited plan removes the caps and unlocks the full image and voice features.

How much does Nastia AI cost in 2026?

$15.99 per month at list price for Unlimited. Annual-billing promotions rotate and have been tracked as low as $4.17-$8.33 per effective month. Verify the total at checkout, because the advertised promo and the billed amount don’t always match.

Is Nastia AI safe and private?

It’s a browser-based platform with no app-store intermediary, and chats are uncensored by design. As with any companion app, assume anything you type is stored on company servers and skip sharing real identifying details.

Nastia vs Replika – what’s the difference?

Replika is the polished, app-store-safe option with strict content rules. Nastia is the uncensored, web-first alternative with deeper customization and lower pricing. Most people choosing between them are really choosing between polish and freedom.
