Start with memory, because that shapes every conversation after the first
The feature that separates these apps more than anything else is what a companion carries between sessions. Read the memory description closely, since the wording used by each service hides a lot. AI Angels keeps persistent memory across sessions and offers it on the free tier. AIGirlfriends.ai holds onto chats across weeks and months, which is a different promise from a short buffer. Backyard AI lists memory up to 100,000 tokens on Pro, so that allowance is tied to a paid plan rather than offered to everyone.
AIAllure retains deep conversational memory, Candy.ai remembers chat context and persona, and Baratnoim.hu keeps chat history and preferences. AI Podruga remembers all conversations, Botify AI remembers themes across sessions, and AI Punca adapts to user preferences. Each of these describes continuity in a different way, so the useful question is not whether memory exists but how far back it reaches and whether it is a summary or a stored history.
The comparison is easier once you read the full reviews for the services you are weighing. The AI Angels review and the AIGirlfriends.ai review show the same two kinds of promise from different angles, and the Backyard AI review is the place to look when the memory ceiling is the deciding factor.
Media features split into clear groups
Image, video and voice support separate the field more sharply than memory does. AI Angels, AIAllure, AIGirlfriends.ai and Botify AI all offer image generation, video generation and voice together, which is the fullest combination in this group. Botify AI is notable because it combines that full set with apps on more than one operating system.
Elsewhere, the set narrows. AI Girlfriend and Candy.ai offer image generation but no listed video or voice feature. AI Punca adds voice to image generation, as do AI Podruga and Baratnoim.hu. Baibu is the outlier in the other direction: it offers voice but no image generation and no video generation. A reader who mainly wants conversation with spoken replies would treat Baibu differently from a reader who wants pictures, and the rankings in our AI girlfriend apps list make that split visible side by side.
Where a brand sits in the full-feature group or the narrower one, the individual reviews set out the detail. The AIAllure review covers a service in the full group, while the Baibu review covers the voice end of the range.
Platforms decide whether a service fits your habits
Where an app runs is the quickest way to rule a service in or out. Botify AI is the broadest here, listed on web, iOS and Android. Backyard AI is listed on iOS, so a reader on another screen should check before committing. AI Girlfriend, AI Punca, AIAllure, AIGirlfriends.ai, Baibu and Baratnoim.hu are all listed on web, which means they run in a browser rather than needing an install.
A web-only service has practical consequences for privacy and storage, because your history lives in browser storage tied to one device rather than spreading across an app ecosystem. That is a question to raise with the service itself, and the general terms page for a provider is usually the most direct place to look. Our AI companion apps ranking sorts services by what they offer, and the AIGirlfriends.ai review is a useful example of a web-only service to read before you subscribe.
Price and what is free, read in that order
Compare price after you have narrowed the field by memory, media and platform, because a low headline price on a service that lacks the features you need is not a saving. Within a single service, the more useful comparison is the free allowance against the paid tiers, since that determines what you can judge before paying. AI Angels is the clearest case in this group: persistent memory across sessions is available on the free tier, so the thing most likely to decide whether you stay can be tried at no cost.
The other services in the list are better judged on what their paid plans add, particularly where a feature is tied to a plan. Backyard AI's larger memory allowance sits on Pro, so the headline figure is not what every subscriber receives. If budget is the deciding factor, the AI boyfriend apps and AI girlfriend apps lists let you scan several services at the same level of detail rather than judging one in isolation.
What the listing does not settle
Several things readers ask about are not settled by the details above, and it is better to leave them open than to guess. Retention periods for stored memory, whether a free tier keeps its history after a subscription ends, and how deletion requests are handled are all questions for each provider. Billing terms and cancellation rules are stated by the services themselves and should be read on the provider's own terms page before you pay.
The same caution applies to the word free itself. A service may describe an allowance as free while still requiring an account, and an account is a data trail of its own. Take the memory, media and platform facts above as the comparison, then check the terms for the rest.
A short order of work
Decide which features are non-negotiable, in this order: memory first, then the media you actually want, then the screen you will use. That narrows the field quickly, because the groups do not overlap much. AIAllure, AIGirlfriends.ai and Botify AI cover the full media set, Baibu covers voice alone, and the middle group mixes image generation with voice in different combinations.
Only after that is the price comparison worth making, and it is worth making against the free allowance rather than a single figure. Read a few reviews from the shortlist, check each provider's billing and cancellation terms, and the choice tends to make itself.
