Why it helps

Built for the exact moment long conversations get heavy.

The extension keeps the workflow simple: pick how many messages stay visible, keep working, and load older messages only when you need more context.

01

Recent messages stay responsive

Newest user and assistant messages remain visible so the conversation stays usable while older history is deferred.

02

Load older context on demand

A visible page button lets you bring back older messages instead of forcing everything to render at once.

03

Configurable message window

Choose how many recent messages stay visible from the popup. The default is 30 messages.

04

Local optimization stats

See rendered and deferred message counts, plus an estimated load reduction, without storing chat content.

05

Minimal permissions

Runs only on chatgpt.com and uses local extension storage for settings.

06

No setup ceremony

Enable it from the popup, set your visible message count, and continue using ChatGPT normally.
