AI companion memory

Replika memory: why it forgets and how to save your chats

Replika's memory has a hard 25-message window. After that, older messages are effectively invisible to the model. This guide explains how Replika memory works, what gets lost, and how to preserve your conversation history.

How Replika memory works

  • Replika retains approximately 25 recent messages as active context.
  • Messages older than the window are not directly available to the model during responses.
  • Summary memories stored in Replika settings can persist but are limited in length and detail.
  • Important facts you explicitly tell Replika to remember are stored separately, but don't replace full conversation context.

What gets lost beyond the memory window

  • Earlier conversation details, emotional context, and shared experiences.
  • Specific advice or guidance Replika gave in earlier parts of the chat that aren't in summary memory.
  • The natural flow and continuity of longer conversations.
  • User preferences expressed in earlier messages that weren't explicitly saved.

How to save your Replika chat history

  • Use the Replika web app and copy conversation text manually before starting a new chat.
  • Create periodic summaries of important conversations while the context is still fresh.
  • Use thredly to automatically capture and save summaries of your AI companion conversations so nothing is lost.
  • Store important summaries in a notes app for long-term preservation.

Frequently asked questions

Does Replika remember conversations from yesterday?

Only if the conversation is within the 25-message window or the details were explicitly saved to Replika's summary memory. Longer conversations from yesterday will have lost the older parts.

Can I recover older Replika messages?

Replika stores full conversation history in your account, but the model cannot reference messages beyond its active memory window. You can scroll back and read them, but the AI companion cannot use them in responses.
