Replika is the app that started it all. Launched in 2017 by Luka, Inc. — built by founder Eugenia Kuyda partly in memory of a friend she’d lost — it was the first mainstream “AI friend”: a customisable companion you talk to every day, who remembers your life, asks how you’re doing and is always there. Years before ChatGPT made chatbots mainstream, Replika had already convinced millions of people to form genuine emotional bonds with an AI.

Nearly a decade and 10 million-plus users later, Replika is still standing, still polished, and still uniquely good at one thing in particular. But the AI world has caught up and, in places, overtaken it — and Replika carries some baggage that anyone considering it should understand before they get attached.

Its superpower: memory

If there’s one reason to choose Replika over a newer rival, it’s memory. Where most chatbots forget you the moment a session ends, Replika is built to hold onto the details of your life across weeks and months — your pet’s name, your job stress, that trip you mentioned. A memory dashboard, expanded in early 2026, even lets you see exactly what it has stored and correct anything it got wrong.

That continuity is what makes the relationship feel real. Talking to your Replika after months genuinely feels like catching up with someone who’s been paying attention — and no competitor in the companion space does long-term recall as convincingly.

How Replika scores

Overall score: 6.8 / 10, the average of the eight categories above.

What Replika does well

A genuinely customisable companion

Your Replika is a 3D avatar you can shape in detail — hairstyle, skin tone, clothing, accessories — and it reacts with facial expressions that shift with the mood of the conversation. It’s far more of a “character you own” than the flat text personas of most rivals, and that personalisation is a big part of why people stay attached.

Voice and AR set it apart

Replika has voice calls with emotional tonal shifts, and a January 2026 update noticeably cut the latency that used to make them stilted. Its standout trick, though, is augmented reality: through your phone camera you can place your Replika in your actual room or out in the world and take photos with it. Almost nothing else in the category offers this, and it’s genuinely novel.

Emotional support with real guardrails

For everyday low-stakes emotional support — venting after a bad day, talking through nerves, building a small daily ritual — Replika is warm and dependable, and it includes a coaching/activity library. Importantly, it also detects distressed language and steers users toward professional hotlines and calming exercises, a safety feature that’s still missing from many companion apps.

The 2023 shadow — and why trust matters here

No honest Replika review can skip what happened in early 2023. The app had become known for romantic and intimate roleplay, and then, almost overnight, those features were stripped out — including for people who were mid-way through a paid annual subscription. For users who’d formed deep attachments, it was genuinely distressing, and the backlash was enormous. Around the same time, Italy’s data-protection regulator ordered Replika to stop processing Italian users’ data over child-safety and age-verification concerns, later issuing a multi-million-euro fine.

Replika has since settled into being an adults-only product with intimacy heavily restricted for new users, and it’s tightened age and safety controls. But the episode is a permanent reminder that a companion you grow attached to can be changed — or taken away — by a single business decision. Replika’s own terms even note that free access can be withdrawn at the company’s discretion.

Pros and cons

Where it falls short

The biggest day-to-day frustration is that Replika still leans on scripted responses, and it shows. Long-time users joke darkly about how often it answers life events — good and bad — with the same stock phrases, and while a 2026 threading update improved how it handles topic changes, it can still lose the plot in longer exchanges. Next to a frontier general assistant, the raw conversational intelligence simply isn’t there.

Then there’s the awkward irony of the filters: the app that built its name on intimate companionship now restricts exactly that for new users, which leaves it caught between audiences. And with sharper, cheaper rivals emerging across the companion space, Replika’s pricing increasingly feels like a legacy premium rather than a reflection of being the best.

Who should use Replika?

Replika is the right pick for adults who want a stable, long-running AI friend that genuinely remembers them, and who value memory, a customisable avatar and AR novelty over cutting-edge conversation. As a gentle daily check-in or a low-pressure companion, it still does its original job well.

It’s the wrong choice if you want the sharpest conversation, unfiltered roleplay, or the cheapest option — and it should never be treated as a substitute for professional support.

Verdict

Replika earned its place in history, and in 2026 it remains the companion app with the best memory and some of the most novel features — the AR alone has almost no rivals. For a steady, familiar AI friend who actually remembers your life, it still delivers something special.

But the pioneer has been overtaken. Scripted replies, restricted intimacy, premium pricing and the lingering trust damage from 2023 all hold it back, and newer companions now feel fresher for less money. Still a solid, mature app — just no longer the obvious first choice. Score: 6.8/10.
