Overview

Read and search your entire ChatGPT conversation in one fast tab, including messages ChatGPT hasn't loaded. Stays on your device.

Long ChatGPT conversations are hard to work with. ChatGPT now loads them a few turns at a time, so Ctrl+F can't find what you haven't scrolled to, and getting back to something from an hour ago means a lot of scrolling. LightSession fixes that for people who live in long chats, like researchers, writers and developers. READ THE WHOLE CONVERSATION • One click opens the entire chat in its own tab, formatted, with headings, tables and code blocks. • An outline of your prompts on the side lets you jump anywhere. • Find in conversation searches every message, with highlights. • Export the conversation as a Markdown file. • It runs in a separate tab, so ChatGPT stays fast while you read. SEARCH EVERY MESSAGE • Search the whole chat from a panel next to it, including messages ChatGPT hasn't loaded. • The exact phrase comes first. If there's no exact match, you get the messages that contain all the words. • Filter by your messages or ChatGPT's, and open any result in the reader. • With nothing typed, the panel lists every prompt you wrote. PRIVATE BY DESIGN • Your conversations are indexed on your device, in the extension's local storage. • Nothing is sent to the developer or to anyone else. There are no accounts and no analytics. • Temporary chats are never saved. • Uninstalling removes everything. HOW TO USE IT Open a ChatGPT conversation. Use the two buttons on the right edge, the toolbar icon, or ⌘⇧F (Ctrl+Shift+F on Windows and Linux). LightSession is an independent project. It is not affiliated with, endorsed by or sponsored by OpenAI. ChatGPT is a trademark of OpenAI.
