Memory decides whether a companion feels continuous
An AI companion is a chat service with a memory layer attached. The conversation on screen is short, but the memory layer is what carries a detail forward, so the same character can pick up a topic you mentioned much earlier. For an adult comparing services, that question comes first: how much does this service remember, and for how long? Get the memory answer and the rest of the comparison makes more sense, because it changes what every other feature is worth to you.
The published answers differ widely. AIGirlfriends.ai remembers chats across weeks and months. Baratnoim.hu remembers chat history and preferences, Botify AI remembers themes across sessions, AIAllure keeps deep conversational memory, and AI Podruga remembers all conversations. AI Punca takes a different route and adapts to what you prefer, while AI Angels keeps memory across sessions and includes it on the free tier. Candy.ai remembers chat context and persona, which is a narrower promise again.
Botify AI is a useful second example, because holding themes rather than full transcripts is a deliberate difference: a service can keep what you enjoy talking about without storing every line. Backyard AI measures its memory in tokens, and the amount depends on the plan, so read that review for the figure that matches the tier you would buy. AI Girlfriend is listed for the web with image generation, so check its review for the memory detail before you commit.
Media is the easiest yes or no filter
Media features are the clearest comparison you can make, because each one is a simple yes or no, and that makes them a good first cut. Image generation is listed for AI Angels, AI Girlfriend, AI Punca, AIAllure, AIGirlfriends.ai, Baratnoim.hu, Botify AI and Candy.ai. Baibu is the exception, with no image generation.
Video narrows the field again. AI Angels, AIAllure, AIGirlfriends.ai and Botify AI each list video generation, while Baibu does not. If you want moving pictures out of a chat, that alone removes a large part of this group.
Voice is the most widely listed of the three. It is offered by AI Angels, AI Punca, AIAllure, AIGirlfriends.ai, Backyard AI, Baibu, Baratnoim.hu and Botify AI. Baibu makes the trade-off plain: voice yes, images no, video no. A voice-led service ranks higher if you prefer talking to looking, and drops away if pictures are the reason you are here.
Which device it has to run on
Platform decides how usable any of this is, because a service you cannot open is one you will not keep. Most of the group is listed for the web, including AI Girlfriend, AI Punca, AIAllure, AIGirlfriends.ai, Baibu, Baratnoim.hu and Botify AI. A web service works from a laptop and from a phone browser, which keeps your options open.
Botify AI is the broadest of those listed, with web, iOS and Android, so it suits you if you move between devices and want the same history in front of you. Backyard AI is listed for iOS, so it belongs on a phone-first shortlist. Settle this before anything else, because it is quick to check and it can end the comparison early.
Price, free use and how the billing works
Cost decides whether a service is worth paying for, and it belongs in the review rather than in a feature list. Before you subscribe, write down the entry price, what the free allowance covers, whether a trial starts a paid plan on its own, and how a cancellation is handled. Those answers are what you are really buying, and they are easier to weigh side by side than a long feature list.
One feature answer already points at the free side. AI Angels lists its memory across sessions together with a free tier, so a trial there covers the feature that carries the most weight in long use. For the other services, read the free offer as stated on each review page before you rely on it, particularly if a free visit is what pushed you towards paying.
The AI girlfriends and AI sex chat rankings page is the fastest way to rule options out, since it sets the services next to each other and lets you drop any whose price or platform does not work for you. Only the survivors are worth reading about in detail.
Privacy and the record a long memory leaves
A companion service is built on conversation, so what you write tends to end up inside its memory. That makes stored memory a privacy decision rather than a feature to boast about. A service that remembers chats across weeks and months keeps a longer trace of you than one that only adapts to your stated preferences, and the longer the memory, the more you should read about clearing it.
Ask three questions for every service on your list: how long a memory is kept, whether you can clear it, and whether generated images and voice are handled on the same terms. Answer them from the reviews rather than the feature lists, and take two services at a time so the wording lines up. A memory that lasts for years should never be an accident of design.
A shortlist routine that takes a few minutes
Run four passes in order. Drop any service that does not run on the device you have. Check memory, because that is what makes long use feel continuous. Add only the media you actually want, whether that is images, video or voice. Then compare price, the free allowance and cancellation for whatever is left, and read the full review before you pay.
The order matters, because each pass shortens the list and the last one takes the longest. If you already know you want voice and a phone app, you will finish with a very short list. If you want images and a long memory, you start wider. AIAllure is worth reading closely in that second group, since it lists images, video and voice together with deep conversational memory. Whichever group you land in, let the rankings narrow the list and the reviews settle it.
