Memory for an AI companion

Recall a small amount of relevant personal context without replaying the full chat.

Do not add every chat turn. Recall before responding, then store only a durable fact the user clearly disclosed or asked the companion to remember.

import { FishMem } from "@fishmem/sdk";

const fishmem = new FishMem({
  apiKey: process.env.FISHMEM_API_KEY!,
});

async function recallForReply(userId: string, message: string) {
  const { results } = await fishmem.memories.search({
    query: message,
    user_id: userId,
    top_k: 5,
  });

  return results.map((item) => `- ${item.memory}`).join("\n");
}

After the model or application has identified a durable, self-contained fact:

await fishmem.memories.add({
  content: "The user's dog is named Biscuit and had surgery in July 2026.",
  infer: false,
  user_id: userId,
  metadata: { source: "companion-chat" },
});

Provide controls to inspect, correct, export, and delete these memories. Sensitive personal facts should have a stricter write policy than ordinary product preferences.
