Start with the three features that change daily use
Most AI companion services look alike on a listing page: a chat window, a character picker, a subscription button. The details that change how a session actually feels sit in three places, how long the service remembers you, whether you can speak instead of typing, and whether you can make pictures or clips of the character.
Those three are worth checking before price, because a service that forgets you every morning can cost less and still feel worse than a pricier one that recalls your name and your preferences. For adults comparing services, the comparison work is mostly about finding the gap between what a listing advertises and what your plan includes.
The rankings of AI girlfriends and AI sex chat set price, privacy and billing side by side. Use them to shortlist, then work through the shortlisted services with the checks below.
Memory: the feature that varies most
Memory descriptions differ in kind, not only in size. AI Podruga keeps all conversations, and AIGirlfriends.ai keeps chats across weeks and months, so both build a longer history. Candy.ai holds chat context and persona, while Baratnoim.hu keeps chat history and preferences.
Others describe memory as adaptation rather than archive. AI Punca says it adapts to user preferences, Botify AI remembers themes across sessions, AIAllure retains deep conversational memory, and ChatVika says its characters remember you across conversations. The AI Punca review is a good place to see how a preference based service reads in practice.
Two entries tie memory to a plan rather than to the account. Backyard AI gives you a large memory allowance on a plan it calls Pro, and AI Angels lists persistent memory across sessions with the free tier included. Ask which tier your habits would sit on before you pick a subscription length, and read the Backyard AI review and the AI Angels review for the plan detail.
Voice: close to standard, so check quality not presence
Voice is listed for most services in this group: AI Angels, AI Punca, AIAllure, AIGirlfriends.ai, Backyard AI, Baibu, Baratnoim.hu, Botify AI, Candy.ai, Chai AI and Character.AI. Presence alone therefore tells you very little.
What changes a session is clarity, how quickly the reply comes back, and whether the voice holds up through a long conversation. Those are the points to raise in the reviews, and the Botify AI review is a reasonable starting point for the sort of detail to look for.
Baibu is the useful contrast. It has voice, and it is the one service in the group without image or video generation, so it suits readers who want spoken conversation and text and nothing else. The Baibu review covers what that combination feels like day to day.
Images and video: what you can make
Image generation is listed almost everywhere: AI Angels, AI Girlfriend, AI Podruga, AI Punca, AIAllure, AIGirlfriends.ai, Baratnoim.hu, Botify AI, Candy.ai, Chai AI and Character.AI. Baibu is the exception, with no image generation listed.
Video generation is the narrower feature. It is listed for AI Angels, AIAllure, AIGirlfriends.ai, Botify AI, Candy.ai and Chai AI, so a shorter list than images and much shorter than voice.
Check where a media feature sits in the plan before you pay for it. A listed feature may sit in a higher tier, and the individual reviews set out what each tier includes, so the listing alone is not a promise of access.
Price, free tiers and billing
Media and memory are rarely part of the entry tier in the same way as chat. Two examples in this group show how differently that is handled: Backyard AI places its memory allowance on a plan it calls Pro, while AI Angels lists its persistent memory on the free tier.
The practical move is to compare the same three things for every candidate: the entry price, the price of the tier that unlocks memory and media, and the billing period you would be signing up for. The rankings page holds the price side of that comparison, and the individual reviews carry the billing names and cancellation terms exactly as each service states them.
Read those terms before you pay rather than after, because billing names and cancellation terms differ between services and change more often than the features do.
Privacy and the memory you create
A memory that persists across sessions is holding earlier conversation, so the fair question is what the service keeps and for how long. Read what each review says is retained, and think twice before sharing identifying details in a chat designed to remember you.
Longer memory is useful and sensitive at the same time. AI Podruga keeping all conversations and AIGirlfriends.ai keeping chats across weeks and months are generous features and generous stores, and that trade is worth naming out loud for yourself.
Pair the privacy check with the billing check. If you are unsure what a service holds about you, treat that as a reason to read the AIAllure review and the AIGirlfriends.ai review in full before you subscribe.
A short checklist before you subscribe
Memory: does the service keep everything, or only themes and preferences, and does that sit on the free tier or a paid one?
Voice: listed as available for nearly every service here, so judge clarity and speed from the reviews instead of from the feature list.
Media: images almost everywhere, video for a shorter list, and Baibu offers neither.
Billing and privacy: read the plan names, the price of the tier you need, the cancellation terms and what is retained, then confirm the service still sits where you expect on the rankings.
