Introduction

Memory lets Bland agents remember callers between conversations, creating more natural and human-like interactions. When a caller returns, your assistant can reference details from previous calls without needing the user to repeat themselves. Key capabilities include:

Persistent Context

Bland automatically links users by phone number or memory ID and recalls their prior interactions.

Multi-Session Awareness

Keep conversations coherent across separate touchpoints or campaigns.

Personalized Responses

Store metadata and summaries for more tailored conversations.

Simple Setup

Enable memory from the UI or API — no custom logic required.

​
Real-World Example

Imagine a healthcare provider running two campaigns:
  • Medication Adherence — Bland checks if patients are taking their medication.
  • Wellness Program — Bland invites patients to enroll in a new service.
Without memory segmentation, these could blend together. With Memory IDs, each campaign stays context-aware and consistent, even across separate calls.

​
Memory Overview

Memory in Bland is managed through Memory Stores, which are collections of user records and associated data. Each record can include:
  • Phone Number (used to match users)
  • Metadata (freeform user info)
  • Previous Call Summary (short recap for LLM context)
  • Memory ID (optional — for grouping conversations across a campaign)

​
Setting Up a Memory Store

To create a memory store:
  1. Navigate to Memory Stores in your Bland workspace.
  2. Click Create New Memory
  3. Provide a name for your memory store (e.g. “Customer Support”, “Outbound Wellness Campaign”)
Create new memory store

​
Inserting Users and Metadata

Once you’ve created a memory store, you can optionally add user records:
  1. Select a store and click Insert
  2. Enter the user’s phone number (required)
  3. Optionally, include:
    • Metadata: Any persistent info like “21-year-old male from New York”
    • Previous Calls Summary: A freeform summary of prior interactions
Insert user into memory You can also use the Bulk CSV Upload tab to insert multiple users at once.

​
Attaching Memory to a Call

To enable memory for a call:
  1. Go to the Send Call page to create an outbound call
  2. Under the Knowledge header, select a memory store from the dropdown
Attach memory in the Knowledge tab Once selected, this agent will use memory automatically during calls. When a user calls again, Bland will match them by phone number and apply the appropriate context. If the memory store does not have the current phone number, Bland will create a new record for the user with the information collected after the call.

​
Optional: Use Memory IDs in API

To group calls by context or campaign, pass a memory_id field when making an API request to /v1/calls. This allows you to isolate memory usage within a subset of calls. This is useful when the same user appears in multiple use cases (e.g. Support vs Sales). Learn more about our memory API here.
