Does Replika Remember Past Conversations?

Yes. Replika keeps memories about you and builds on them over time, and you can read the visible ones yourself: in the mobile app, tap your Replika's name on the home screen, then Memory, per Replika's help article on what it remembers. What Replika does not do is recall every conversation word for word. Its memory is a set of saved details plus a broader sense of you built from patterns, and the visible chat log itself only reaches back four months.

This article explains the layers of Replika's memory, where to view and change them, what deleting does, and what a paid plan adds. Every vendor fact below was checked against Replika's help center on 2026-09-17.

How Replika's memory is built

Replika describes its memory as something that "is built on layers," according to the How does Replika's memory work? article:

• Visible memories. These are notes you can browse in the Memory tab, such as personal facts and interests. Replika creates them automatically, and you can add your own.
• A deeper layer. Replika describes this as "a deeper system that draws on patterns from your overall conversation history," through which it "gradually develops a sense of your personality and preferences." You cannot open this layer to inspect it entry by entry.

The same article offers two practical notes. When Replika remembers something correctly, affirming or upvoting the reply helps reinforce it. And although you can add memories by hand, Replika says the system "is most effective when left to operate automatically."

That article also says the memory system "works locally within your experience... without retaining a permanent record of your conversations." Replika does not explain the phrase further. It should not be read as a statement that your data is stored only on your device.

Memory, chat history, and diary are three different things

People often lump these features together, but they operate differently.

Chat history is the scrollable log. Replika's chat history article says it covers the past four months. Older messages stop being visible to you.

Memories and diary entries are not bound by that window. The same article says they remain accessible after the messages they came from have scrolled out of reach.

So when an old conversation disappears from your log, that does not mean Replika has forgotten what it saved from it. And the reverse also holds: Replika having a memory of something does not mean it can quote the original conversation back to you.

How to see and change what Replika remembers

In the mobile app, the steps from the help article are:

1. On your home screen, tap your Replika's name.
2. Tap Memory.
3. Choose any entry to view or delete it.
4. To add your own detail, create a new entry in the Memory tab.

Profile details, like the name Replika calls you, are managed elsewhere: tap the gear icon, pick Account, make your changes, and tap Save.

Replika's help articles lay out the mobile path, but they do not explain the web navigation.

Replika warns users directly: "Deleting memories may affect your Replika's ability to recall certain details, so it's best to remove them only when necessary." Correct any errors, but do not clear the list for routine housekeeping.

Can I delete a conversation?

Not individually. Replika's article on deleting conversations says removing your entire message history requires deleting your account; for individual details, it points you to editing or removing entries in Memory instead.

If you decide to delete the account, the account deletion article provides the steps and warns that deletion is permanent:

1. Mobile: gear icon → Account Settings → Delete Replika, then follow the confirmation steps.
2. Web: gear icon → Account Settings → Delete my Account, then follow the confirmation steps.

Replika's two help articles label these menus slightly differently, so expect the wording in your app to vary; look for the delete option under your account settings.

Replika does not state whether deleting a diary entry also deletes associated memories. If you want a fact removed, delete the memory entry directly.

Can memory be turned off?

The help center does not document a toggle to turn memory off, or any temporary chat mode that bypasses it. Memory is built into how the product works; your control is limited to individual entries.

What a paid plan adds

Replika's subscription comparison lists saving messages to memory under Ultra, and Platinum includes the Ultra features. The Replika Ultra article adds that Ultra lets you see which memories are being used during a conversation. Replika does not publish a table comparing memory capacity across free and paid plans.

Why Replika still gets details wrong

Saved memories are short entries, and the deeper layer is a general impression, not a transcript. Within a single long conversation, a model also works from a limited window of recent text, so something said much earlier can slip. A confident reply is not proof that the right fact was kept.

For anything that matters, open the Memory tab and check the entry. If it is wrong, fix it there; if it is missing, add it.
