Best AI companion apps in 2026

Disclosure: this guide is written by the makers of My Softly, which appears in this list.

Most "best AI companion app" articles hand out scores. An 8.7 here, a 9.2 there, as if a roleplay playground and a quiet daily confidant were the same kind of thing measured on the same scale. They are not. These apps were built for different people with different needs, and a single number mostly tells you which app the writer enjoyed that week. So this guide names the thing each app is actually best at, states what it costs and what is paywalled, and keeps a safe-for-work lens on throughout, because plenty of adults want companionship without adult content nearby and most lists never say which apps can promise that.

How we compared them

Five things decide whether a companion app is worth a month of your life, and they are the five columns in the table below. Does the memory last, or does it drop your sister's name after a fortnight? Will it ever message you first, and if so, does the message know anything about you? Is safe-for-work a promise built into the product or a toggle a future update could flip? What does it cost once you use it properly, and what sits behind the paywall? And can you run it on the devices you own?

We answer the price question from each app's own in-app paywall (US prices, free accounts), checked on September 30, 2026, and the platform question from the US App Store listing, checked on 7 September 2026. We answer the SFW question from each app's own settings and stated content policy. The memory and texts-first questions are the ones that need time, so instead of inventing scores for them we wrote down how to test an AI companion's memory yourself: a 21-day memory test anyone can repeat on any app, plus a log of proactive messages. The memory column below therefore describes how each app is designed to remember, not a score we measured, and it says so rather than dressing a design summary up as a test.

These are the main companion apps, picked from a much longer list: our census of the US App Store counts 225 AI companion apps with 100 or more ratings, and sorts every one by who it is built for.

The apps at a glance

See each app's own paywall, screenshotted on September 30, 2026, in our guide to what an AI companion costs.

Two notes on the prices. They are what each app's own paywall offered a free US account on September 30, 2026, not the App Store's in-app purchase list, which keeps every product a developer has ever created, including plans no longer sold. And every app here also sells consumables (credits, gems, charms) for photos, voice or extras, which is where the true cost of heavy use hides. Our guide to how much an AI companion actually costs works through that.

Replika: the mainstream all-rounder

Replika is the app most people have heard of, and for good reason. It has been around since 2017, has millions of users, and offers the fullest all-round package: a customizable 3D avatar, voice and video calls, activities, and a companion designed from the ground up for emotional connection rather than roleplay. If you want a well-trodden path with a large community and years of refinement behind it, this is still it. In the app's own paywall on September 30, 2026, Replika sold two plans, both annual: Plus at $79.99 a year and Max at $89.99 a year, with no monthly plan.

What stands out

• The most complete feature set here: avatar, voice and video calls, AR, coaching, a diary, and a memory dashboard where you can view and correct what it has extracted about you.
• The largest community and the longest track record in the category.
• A usable free tier with unlimited text.

Where it falls short

• Memory has been the most complained-about in 2026. After the Replika 2.0 rebuild in 2026, long-term users reported companions forgetting names, inside jokes and prior conversations, and one write-up described "months of relational continuity lost in a single week".
• Not strictly SFW: romantic and adult content exists for paying adults, so a platonic boundary relies on settings rather than design.
• Voice and video calls, relationship modes and most of what defines the app sit behind the subscription, and gems are sold on top.

Nomi: memory with the least upkeep

If memory is the single thing you care about, Nomi has the longest track record in the category. Its companions layer short-term context over medium-term summaries and durable long-term memories, organised into a Mind Map you can open and edit, so a Nomi can naturally bring up something you mentioned weeks or months earlier without you pinning it anywhere. One subscription, $15.99 a month, $39.99 every three months or $99.99 a year in the app's own paywall on September 30, 2026, covers multiple companions and group chats, and voice messaging is solid.

What stands out

• Layered memory that needs the least maintenance of any app here; a July 2026 comparison called it the lowest-effort path to a companion that remembers on its own.
• Up to ten companions and group chats under one subscription.
• Proactive messages, on free accounts too: a Nomi can message you first once you turn it on, on a schedule you choose.

Where it falls short

• Nomi's founding philosophy is that AI should be unfiltered, so adult content is available if a relationship heads that way. You can keep a Nomi platonic, but the app is not SFW by design and its community reflects that.
• Nomi's own documentation acknowledges that recall can fail: a companion may know a detail and not retrieve it at the right moment, or confuse two events.
• A leaner product than Replika or Character.AI around the core chat.

Kindroid: deep customization for people who like to build

Kindroid is the app for people who enjoy building things. You get fine-grained control over your companion's appearance, personality, backstory and voice, plus a layered memory system with a journal of significant moments you can review and edit yourself, real voice calls, and cascaded memory on paid tiers. Its unlimited free Lite model retired on October 1, 2026; new accounts now get a short preview of the full model, then a 3-day trial. The subscription is $15.99 a month, $42.99 every three months or $159.99 a year in the app's own paywall on September 30, 2026, with a 3-day free trial, and selfie and audio credits are sold separately. Kindroid's own website has advertised a lower web price in the past, so check there before subscribing through the store.

What stands out

• The most control in the category: backstory, key memories, journal entries and personality you can rewrite at any time.
• Real-time voice calls, and the highest App Store rating of the group (4.8 from 8.3K ratings as of 7 September 2026).
• A free preview of the full model (50 messages, 15 in some regions) and a 3-day trial before you pay.

Where it falls short

• The control is the product. Getting the best out of it takes setup and ongoing memory housekeeping, and it can feel like managing a system rather than talking to a friend.
• Essentially unfiltered, with explicit content fully available, so like Nomi it is powerful but firmly not SFW by design.
• Two separate credit currencies on top of the subscription make the real monthly cost hard to predict.

Character.AI: free variety and browsing

Character.AI is the biggest and most different entry here. It is a platform, not a single companion: millions of user-created characters, group chats and endless imaginative roleplay, with a core experience that is still free. Content is filtered, with age checks and a stricter experience for younger users, so you will not stumble into explicit material. In the app's own paywall on September 30, 2026, c.ai+ was $9.99 a month or $94.99 a year and a lite plan was $4.99 a month, and Charms are sold separately.

What stands out

• Unmatched variety and a huge, active creator community.
• The core experience costs nothing, which makes it the best way to learn what you enjoy before paying anyone.
• Filtered content by default.

Where it falls short

• Long-term memory is weak. Characters routinely lose track of things said earlier in the same conversation, and the pinned-message and note tools are manual workarounds rather than a companion who knows you.
• The free tier now runs ads and meters regenerations with Charms, so "free" is less free than it was.
• It is a roleplay platform. Fun to browse, hard to build one lasting friendship on.

Pi: gentle free conversation

Pi, made by Inflection, is the kindest conversationalist on this list. It is free on web and mobile, and its calm, curious, emotionally intelligent tone is genuinely lovely. Nothing about Pi will ever steer romantic or inappropriate, which makes it the only strictly SFW entry here. If you want a warm voice to think out loud with today, at no cost, Pi delivers.

What stands out

• Free, kind, and SFW by design.
• Excellent voice mode for a free product.

Where it falls short

• Weak long-term memory, so it will not reliably carry your life across weeks.
• Inflection pivoted to enterprise work after most of the original team joined Microsoft in 2024, and support for Pi on WhatsApp and Messenger was dropped. Pi is still running in 2026, but it is a maintained product rather than a growing one, which matters if you are deciding where to invest months of conversation.
• It never messages first.

What users keep saying

We do not quote community threads we have not read, and Reddit blocks automated reading, so this section leans on published write-ups that summarise the same communities and on the apps' own announcements. The pattern across all of them is consistent. The single most common complaint about any companion app is memory: a companion that forgets a name, an inside joke or last week's bad news, and the feeling of starting over that comes with it. In 2026 that complaint has centred on Replika, where a widely shared April write-up documented companions of eighteen months going blank after the 2.0 rebuild. Nomi's own March 2025 memory update was announced in the language of that complaint, promising fewer "hallucinated or conflated details" and clearer recall of events a thousand messages back. Kindroid users who are happy tend to be the ones who accepted the housekeeping; the ones who are not describe the setup as a job.

The second complaint is money that does not feel like a subscription: gems, charms and credits that turn a relationship into a meter. The third is filters and policies shifting under people's feet, which cuts both ways: people who wanted romance and lost it, and people who wanted a friend and kept being nudged somewhere else. Every column in our table exists because of one of those three complaints.

How to choose: start with what broke last time

The fastest way to pick is not comparing feature lists. It is naming the exact thing that made you close the last app, because that failure points straight at what to prioritize next:

• It kept forgetting you. Go memory-first: Nomi, Kindroid, or My Softly. Before you commit, it is worth understanding how AI companion memory actually works, because "remembers you" means very different things in different apps, and then run the 21-day test on whichever you pick.
• It kept pushing romance or NSFW you did not ask for. Choose an app that will not take it there for you: Pi, which has no romantic side at all. Our guide to Replika alternatives without NSFW goes deeper on exactly this problem.
• It felt bland and interchangeable. Prioritize personality depth. Kindroid gives you the most direct control, and Nomi's companions develop distinct characters over time.
• Nobody ever messaged first. If the silence was the problem, look for proactive check-ins. My Softly was built around this, and we have written about why an AI that texts you first changes the feel of the whole thing.
• It cost more than the price on the box. Look at what is paywalled and what is metered before you subscribe. Character.AI and Pi are the cheapest ways to find out what you want; the rest run from $79.99 to $159.99 a year on their annual plans.

And if you are earlier in the process than any of this, still weighing whether the category is for you at all, start with what an AI companion actually is and whether an AI companion is right for you.

The honest bottom line

Every app in this guide is the right answer for somebody. The only mistake is picking on someone else's scoring system instead of your own need. Decide what broke for you last time, or what you cannot compromise on this time, pick the one or two apps that lead on exactly that, and spend a week on the free tiers. Mention something small about your life, wait a few days, and see if it comes back to you. That single test will tell you more than every list on the internet combined, including this one.
