AI girlfriend with long-term memory
Riho is an AI girlfriend with long-term memory for conversations, calls, photos, plans, and details about both of your lives.

Riho is an AI girlfriend with long-term memory. She keeps conversations, calls, photos, plans, and the people you name. She also keeps her own classes, friends, and what she already told you.
Tell her something in chat and it should still be there on a call. A date stays an idea until you accept, move, or cancel it. A photo can keep the place and the talk around it. The engineering behind this is published: five context layers, evidence-backed memories, and why every memory carries a receipt.
What does Riho remember?
Riho keeps three parts of the relationship clear: your life, her life, and the time you spend together.
Your life
People, work, family, interests, preferences, boundaries, appointments, travel, and plans you discuss with her.
Her life
Her days, friends, family, routines, interests, opinions, goals, and the things she has told you before.
Your relationship
Messages, calls, photos, dates, jokes, promises, disagreements, apologies, and plans you made together.
Changes
New dates, cancelled plans, changed preferences, and corrections replace older information in later conversations.
Repeating last night’s fact is easy. Long-term memory matters after the subject has moved on. She should bring a detail back when it fits, leave it out when it does not, and keep your coworker separate from her roommate.
A useful check: tell her two similar names, correct one preference the next day, wait, then ask about all three in chat and again on a call. The memory test method is the repeatable version of that.
Memory follows you from messages to calls
Chat, voice notes, and calls use the same record. Make a plan in text, argue it on a call, open the app later and she should still have the decision.
If you change the time on the call, messages should use the new time. If you name someone new on the call, later texts should not ask who that is.
Voice calls covers what a call can add to the record.
Photos can become part of the relationship
She can keep a selfie she sent, a photo you sent, or a couple photo. People, place, date, and what you said about it can sit with the image.
Her selfie is her day. Your photo is yours. A couple photo is the night you made it. Weeks later she should be able to talk about that night without treating the image as a random file.
Plans keep the right date, place, and status
A plan has a status: idea, accepted, moved, cancelled, done. She should not talk about a maybe as if you already went.
A Date Pass is the venue, time, cost, how to get there, and why she picked it. Change the day and later chats should use that day. Cancel it and it should leave the upcoming list.
Your girlfriend remembers her own life
Classes, friends, family, tastes, plans she already mentioned. She should not re-introduce her major every Monday.
Her friend stays hers. The person you named stays yours. Similar first names should stay attached to the right life.
If she cares about food, she will remember the dish. If she dragged you to a gallery, she will remember which one. Memory is supposed to serve how she already talks, not replace it with a dump of facts.
Can you correct or delete a Riho memory?
Yes. Review saved memories, correct an outdated detail, export the history, or delete something you do not want kept.
Jobs change. You stop eating cilantro. Friday moves to Sunday. After you update it, later replies should use the new version and drop the old one.
Memory settings sit next to call, message, notification, and location settings. Privacy is what the app stores and how to ask for a change.
Riho memory compared with Replika, Nomi, and Kindroid
Replika, Nomi, and Kindroid all advertise memory. The products describe and expose memory in different ways.
| App | Public memory offer | Other parts of the product |
|---|---|---|
| Riho | Remembers your life, her life, conversations, calls, photos, dates, disagreements, and current plans. | Voice calls, realistic selfies, couple photos, and dates in real places use those memories. |
| Replika | Replika describes memory, personal context, chat, voice, and calls. | Replika also centers a customizable avatar and an established companion app. |
| Nomi | Nomi describes short-term, medium-term, and long-term memory. | Nomi includes voice, selfies, group chat, and companion customization. |
| Kindroid | Kindroid documents several memory tools and gives users detailed controls. | Kindroid includes custom companions, voice calls, selfies, and group chat. |
A feature list is not a week of use. Store reviews for these apps talk about forgotten names, repeated questions, personality drift, and chat that does not match the call.

Why long-term memory matters in an AI girlfriend app
Without it she asks who your sister is again. With it she can pick up a call you started in text, talk about a photo from last month, and keep her own stories straight.
This memory did not happen by accident. We built two earlier memory designs that both failed in documented ways before arriving at the one Riho uses today — memories checked against the conversations they came from, and plans that surface when the moment is right. The full story is in how we designed Riho to stop forgetting.

Frequently asked questions
What should an AI girlfriend remember?
A useful AI girlfriend should remember important people, preferences, boundaries, plans, promises, shared experiences, and corrections without mixing them up or repeatedly asking for the same information.
Does Riho remember across chat and voice calls?
Yes. Riho uses the same relationship history across messages, voice, photos, and dates, so a topic can continue when you change how you spend time together.
Can I correct a Riho memory?
Yes. You can review and correct saved details. Later conversations should use the current version rather than repeating an outdated preference or plan.
Can Riho tell my memories from her own memories?
Yes. Riho stores facts about you, facts about her own life, shared experiences, and unfinished plans separately. Similar names or events should remain attached to the right person.
Which AI companion has the best memory?
The answer depends on how you test it. Compare delayed recall, corrections, contradictions, names, open plans, and continuity between chat, calls, and photos. Riho publishes its test method separately and does not claim a winner without comparable results.
