# Longer Memory

Does your character keep forgetting what you just told them? Their favorite food, the pet name only the two of you use, the promise you made yesterday — Longer Memory is the feature that makes your character actually **remember** all of it, even as the conversation stretches on. It's not complicated. Stick with this guide and you'll have it all figured out in five minutes.

***

## What is Longer Memory?

Think of an AI character's memory like **the space on a desk**. When the desk is small (= the memory capacity is small), you have to shove older papers off the edge to make room for new ones. So as a conversation grows longer, the character slowly starts forgetting the things you said at the beginning.

**Longer Memory** widens that desk. It increases how much of the conversation a character can "have in view" at one time (this is called **context**), so they can remember things from much further back.

> **Why this matters:** The more context a character can hold onto, the smarter, more consistent, and more alive the conversation feels. As a rule of thumb, the more they remember, the better the experience.

***

## Your base memory capacity depends on your plan

Each plan comes with a default "desk size." The **K** after each number refers to the count of tokens (a token is roughly a chunk of a word or character). The bigger the number, the more the character can remember.

| Plan         | Base Memory Capacity | In a Nutshell                     |
| ------------ | -------------------- | --------------------------------- |
| **Free**     | Short · 8K           | Perfect for short chats           |
| **Silver**   | Medium · 16K         | Plenty of room to keep going      |
| **Gold**     | Long · 32K           | Deep, long roleplay               |
| **Platinum** | Extended · 64K       | Remembers it all, start to finish |

These are just the **defaults**. If you want your character to remember even further back, you can crank it up yourself with the **Memory Dial** below.

> **Heads up!** Every plan comes with a base capacity, and anything beyond that draws on RP / your weekly allowance. We'll walk through the details below.

***

## Memory Dial — raise your memory yourself

If the base capacity isn't enough, you can turn the **Memory Dial** to push your memory capacity all the way up to **1M (one million tokens)**. Like turning up the volume on a radio, you use a slider to decide just how deep you want the memory to go.

### How to use it

1. Open the **Longer Memory** tab in the sidebar of your chat screen.
2. Switch the feature **On**.
3. Slide the **Memory Dial** up as far as you'd like.
4. Before you send, check the **estimate** the app shows you, then send.

> **Good to know:** The deeper you go with memory (= the higher you set the dial), the faster your weekly allowance and RP get used up. It's a bit like making your character read a longer "review note" with every message, and that extra effort comes at a cost. That's exactly why we always show the **estimated cost** on screen right before you send — no surprises.

***

## How is the cost calculated?

The core of it first: **chatting with the Default model is unlimited on every plan.** Extra costs only kick in "when you go deeper with memory than usual" and "when you use premium settings."

* **RP is deducted only once per message** (your send + the AI's reply, bundled together).
* The heavier the settings (deeper memory, longer replies, bigger characters), the faster your weekly allowance / RP runs down.
* That's why we show you the **estimated cost** before you send. [Red Points & Costs](/redchat.app/guides/red-points-and-costs.md)

> **You never get locked out:** Even if your weekly premium allowance or your RP runs dry, **the Default model is unlimited for everyone**, so the conversation never stops. Just lighten the memory a touch and keep going.

***

## Auto Summary

If jotting down every detail of your conversation sounds like a chore, try turning on **Auto Mode**. Your character will **summarize the important bits in real time** as you chat and tidy them into your memory notes automatically.

The maximum length a summary note can hold — and the cost — varies by plan.

| Plan         | Auto Summary Max Length | Cost                               |
| ------------ | ----------------------- | ---------------------------------- |
| **Free**     | up to 1,000 characters  | Uses RP                            |
| **Silver**   | up to 3,000 characters  | Uses RP                            |
| **Gold**     | 5,000 characters        | **Included** in plan (no extra RP) |
| **Platinum** | 10,000 characters       | **Included** in plan (no extra RP) |

> **Tip:** On Free and Silver, Auto Summary uses RP, but on Gold and Platinum a larger summary capacity is built right into the plan. If you lean on summaries often, an upper-tier plan goes a lot further.

***

## Pinned Memory

You know how there's always that one piece of info your character **must never forget**? Things like the dynamic between the two of you, the character's name, or a promise that can never be broken. **Pinned Memory** is the spot where you tack those down with a pushpin. No matter how long the conversation runs, this part never gets bumped off the desk.

Pinned Memory is available **on the Gold and Platinum plans**.

| Plan         | Pinned Memory Capacity |
| ------------ | ---------------------- |
| Free         | —                      |
| Silver       | —                      |
| **Gold**     | 1K                     |
| **Platinum** | 5K                     |

> **Why this matters:** In deep roleplay, nothing is more frustrating than a character losing track of a core detail after a long conversation. Pin just the essentials to Pinned Memory, and that part stays alive the whole way through.

***

## Common Snags (Oh No!)

Don't panic. It's almost always one of these.

* **"I increased the memory, but the cost looks the same?"** → Make sure you checked the **estimated cost** before sending after raising the Memory Dial. The higher the dial, the faster the deduction.
* **"I'm out of RP."** → No worries. **The Default model is unlimited**, so the conversation keeps going. Lighten the memory a bit, or top up your RP to go deep again. [Red Points & Costs](/redchat.app/guides/red-points-and-costs.md)
* **"I can't find Pinned Memory."** → Pinned Memory is **Gold/Platinum only**. Check your current plan.
* **"My Auto summaries keep getting cut off."** → You've hit your plan's Auto Summary max character limit. Check your plan's cap in the table above, and consider an upper-tier plan if you need more room.

***

## Tips for deeper memory

* **Go long only where it counts.** You don't need every conversation to remember all the way up to 1M. Usually the default, or one step up, is plenty — and it saves on cost.
* **Put the essentials in Pinned Memory.** If you're on Gold or Platinum, pin down the settings that can never be forgotten.
* **Leave summarizing to Auto Mode.** If writing things out yourself is a hassle, Auto Summary will organize the key points for you.
* **Check the estimated cost before sending.** Glance at the cost each time you raise the dial, and you'll never get caught off guard by a sudden RP drop.

***

## Recap

* Longer Memory widens your character's "desk" so they remember further back.
* Base capacity is **Free 8K / Silver 16K / Gold 32K / Platinum 64K**, and you can raise it **up to 1M with the Memory Dial**.
* The deeper you remember, the faster your weekly allowance / RP runs down — but we always show the **estimated cost before you send**.
* **Auto Summary** (Gold 5K · Platinum 10K included) and **Pinned Memory** (Gold 1K · Platinum 5K) let you lock down your key memories nice and tight.
* And above all, **the Default model is unlimited for everyone**, so the conversation never stops.
