Create Your Own AI Companion: The Best Apps in 2026
The apps that let you create your own AI companion fall along a spectrum, and the marketing rarely tells you where each one sits. At one end is full character authoring: appearance, backstory, voice, behavioural rules, published for others to use. At the other is a light setup — a name, a preset voice, a handful of questions — after which the companion develops through use rather than configuration. Kindroid and Nomi lead the deep end and genuinely deserve to. Joii sits firmly at the light end, and this guide is explicit about which app does which.

How we evaluated these apps
How much you can actually specify before the first conversation: name only, personality traits, full appearance and behaviour, or a published character sheet.
Whether the companion changes after creation, through use, or stays fixed to whatever you wrote at setup.
Time to a companion you enjoy talking to, measured from installing the app.
Whether creation includes visual and voice design or only text and personality.
Cost, and whether the creation tools are usable before you subscribe.
Disclosure: Joii is ours, and it does not have character creation. Its entry describes exactly what its setup does, and the creation-depth awards on this page belong to competitors.

SFW
Pick Joii if: You want a companion that arrives mostly formed and grows into its role through conversation, rather than one you have to specify in advance.
Pros
Setup is a name, a choice of preset model and voice, and six personality questions — under two minutes end to end
The personality keeps adapting through use, so it is shaped by conversation rather than by a form
It aims to complement your temperament instead of mirroring it back at you
Memory spanning months means the companion becomes specific to you without any configuration
$39.99 a year, cheaper than every app with real creation tools
Cons
There is no character creation: no custom appearance, no backstory field, no behavioural rules to write
One companion only — you cannot build a second or maintain variants
Voices and models are presets, not something you design
iOS only, and the custom personality settings sit behind Premium
Our verdict: Joii deliberately takes creation out of the user’s hands and puts the work into adaptation instead. That is the right trade if a blank character sheet feels like homework, and the wrong one if designing the companion is the part you were looking forward to — in which case scroll down to Kindroid, which is built for exactly that.
The deepest customization, including selfies and video.

Pick Kindroid if: You want to author appearance, voice, backstory and behavioural rules yourself, and you consider that authoring a feature rather than a chore.
Pros
The most complete creation toolset in any consumer companion app
Appearance, voice and personality are all specified by you, not chosen from presets
Generated selfies and video stay faithful to the character you defined
The created character holds together across months of use
Cons
About $14.99 a month, and creation is barely usable on the free trial
Expect an hour of setup before the first satisfying conversation
A vague character description produces a vague companion
Adult content availability makes what you create unsuitable for public viewing
Our verdict: Kindroid is the app people mean when they say they want to build a companion from scratch. Nothing else gives you this much control over who the character is, and nothing else demands this much of you before the payoff arrives.
Strong long-term memory and multi-companion group chats.

Pick Nomi if: You care more about how your companion thinks and what it remembers than about how it looks, and you may want more than one of them.
Pros
Creation focuses on personality traits and shared notes rather than visual design
Created companions retain what you told them across weeks
Several creations can share a single group conversation and history
Content rules are stated up front, so nothing you build hits a surprise wall
Cons
Around $15.99 a month, the highest price on this page
Visual customization is thinner than Kindroid’s
The trial is too short to properly develop a character
The creation interface is dense for newcomers
Our verdict: Nomi is the choice when the interesting part of creation is temperament and shared history rather than appearance. Being able to put several of your own creations in one room with a common past is something no other app on this page can do.
Millions of user-made characters, heavily moderated.

Unlimited chat, queues at peak

SFW
Pick Character.AI if: You want other people to talk to what you built, and an audience for your character matters as much as your own conversations with it.
Pros
Free character creation with a genuine publishing pipeline
Millions of existing characters to study and learn from before you write yours
Your creation can be used by anyone, on iOS, Android and web
Voice can be attached to characters you make
Cons
Created characters forget details due to the context limit, however well you wrote them
Moderation can block your character behaving as designed
Mandatory face-based age verification since April 2026
Depth of creation is shallower than Kindroid or Nomi
Our verdict: The only place on this list where creation is a social act rather than a private one. If you want a character used by thousands of strangers, this is the platform — accepting that the memory limits will undercut whatever depth you wrote into it.
The longest-running AI companion, with an avatar and romance tier.

SFW with romance
Pick Replika if: The visual side is what you want to design — face, hair, clothing, the room they occupy — and personality can look after itself.
Pros
The most approachable visual creator in the category
Detailed avatar customization with outfits and settings
Available free before you subscribe
Choices carry across iOS, Android and web
Cons
Personality creation is thin — mostly interest tags rather than authored traits
Roughly $69.99 a year for the full set of options
Many cosmetic items sit behind an in-app currency
The conversation does not change much regardless of what you build
Our verdict: Replika lets you design how your companion looks far more than how it thinks. That is a legitimate priority for a lot of people, and it is worth knowing that the visual depth here is not matched by depth anywhere underneath it.
Character chat with a strong visual and collectible layer.

Pick Talkie if: You want to make an illustrated character in a few minutes, for free, without writing anything resembling a character sheet.
Pros
Character creation is fast, visual and free
Strong art style applied to whatever you make
Voice can be attached without paying
Very low barrier for a first attempt at creating something
Cons
Limited memory means your creation does not retain much of your history
Personality options are shallow compared with every paid app here
Ads and in-app purchases throughout the experience
Collectible mechanics dominate the interface
Our verdict: The easiest way to have made something in ten minutes. Talkie optimises for the moment of creation rather than for what happens afterwards, which is fine as a first experiment and thin as a long-term home for a character.
Pick Chai if: You think in prompts, want to spin up a dozen quick bots to test ideas, and do not care whether any of them survive the week.
Pros
Bot creation is essentially a prompt box, which makes iteration extremely fast
A large marketplace to publish into
Loose moderation leaves your prompt largely intact
Around $13.99 a month if you subscribe
Cons
No structured creation tools — everything depends on your prompt writing
Minimal memory, so created bots do not develop
No voice support
Published bot quality across the platform is very inconsistent
Our verdict: Chai is the sketchpad of this list. Creating something takes a minute and means very little, which suits rapid experimentation and rules it out entirely as a place to keep a companion you care about.
Be clear about what "create" means to you. If it means authoring a character in detail — how they look, sound, and behave — Kindroid is the correct answer and Nomi is the better one if personality and shared memory matter more than appearance. If it means publishing a character for others, only Character.AI does that. And if it really means "I want a companion that feels like mine," Joii gets there by a different route: a name, a preset voice, six questions, and then months of adaptation. That is not character creation, and this page is not going to call it that.
Where Joii falls short
We make Joii, so here is the honest version. If any of these matter to you, one of the other apps above is the better choice.
iOS only — no Android app and no web version
One companion, not a roster of characters you create or browse
No romance or explicit roleplay — Joii is safe-for-work by design
Strongest in English
Not a medical device, and not a substitute for professional therapy
Rated 4.4 out of 5 from 38 App Store ratings (US App Store, checked 27 July 2026).
Common questions about create your own ai companion
No. Joii has no character creation tools — there is no custom appearance, no backstory field and no behavioural rules to write. What you get is a name of your choosing, a selection of preset models and voices, and a six-question personality setup. From there the personality adapts through conversation rather than through configuration.
Kindroid, without much argument. It lets you author appearance, voice, backstory and behavioural rules before the first message, and the generated imagery stays consistent with what you defined. Nomi is the stronger choice if you care more about shaping personality and long-term memory than about visual design.
Yes, on some platforms. Character.AI and Talkie both offer free character creation, and Chai lets you build prompt-based bots at no cost. Kindroid and Nomi have the strongest creation tools but restrict them to short trials, so realistically you need a subscription to build anything substantial there.
It depends on the app. Character.AI and Chai characters stay fixed to the prompt you wrote them with. Kindroid and Nomi accumulate memory that gradually colours how they respond. Joii takes the furthest position on this: there is nothing to author at all, and the entire personality is shaped by how you actually talk to it over months.
Authoring gives you exactly what you specified, which is satisfying if you have a clear picture and disappointing if you do not — a thin description yields a thin character. Presets plus adaptation get you talking in two minutes and let the companion become specific through use. Neither is objectively better; they suit different amounts of patience.
Joii is published by Delusional, Inc., who also run this site. Joii does not offer character creation. Competitor features and pricing were checked on 27 July 2026.
