ChatGPT wasn't built for long conversations

As threads grow, performance degrades. These are real user pains.

Freezing in large chats

The interface locks up when conversations hit 50+ messages.

Sluggish scrolling

Scrolling through long threads becomes painfully slow.

Laggy typing

Input delay makes writing responses frustrating.

Heavy code blocks

Syntax-highlighted code blocks consume significant resources.

Excessive DOM rendering

Every message stays rendered, even ones far off-screen.

No organization

Hundreds of chats with no folders or search tools.

Intelligent optimization, not a hack

01

Collapse old messages

Keeps recent messages visible, collapses older ones into lightweight placeholders.

02

Defer heavy content

Large code blocks and off-screen messages are lazy-loaded on demand.

03

Reduce DOM weight

Performance mode strips non-essential animations and effects.

04

Add navigation tools

Search, conversation map, pin messages, and organize with folders.

Free speed boost. Pro power tools.

Core performance improvements are free. Pro adds navigation, search, export, folders, and full control.
