Speed Booster Toolkit vs GPT Master
Updated
Both make ChatGPT easier to live with. Speed Booster Toolkit costs less to upgrade, runs in Firefox and keeps your folders on every computer you use. GPT Master is free to start, with a paid plan for more; its PeerPush listing puts that from $99 a year. Speed Booster Toolkit’s Pro is $7.99, once.
GPT Master’s site says your folders are stored locally in your browser, and doesn’t mention syncing them. Speed Booster Toolkit syncs folders and bookmarks, encrypted, to every browser you use. It also searches inside a long chat, exports to five formats, and its free plan has no limit on less lag, search, the message list and bulk delete.

What we say about GPT Master comes from its own pages, read on October 27, 2026 (gptmaster.app, gptmaster.app/what-is-gpt-master, peerpush.com/p/gpt-master), not from testing it, so “not mentioned” means they don’t say. Prices and plans change. If something here is out of date, tell us and we’ll fix it.
Which one to pick
Speed Booster Toolkit, to pay once
$7.99, once, against a plan from $99 a year. And what most people use every day, less lag, search, the message list and bulk delete, stays free without limits.
Speed Booster Toolkit, on more than one computer
Speed Booster Toolkit puts the same folders and bookmarks in every browser you use, encrypted on your computer first. GPT Master’s site says folders are stored locally in your browser and doesn’t mention syncing.
Speed Booster Toolkit, if you use Firefox
It’s on Firefox Add-ons today, as well as Chrome, Edge, Brave, Opera and the other Chromium browsers. GPT Master’s Firefox version is still planned.
GPT Master, for notes and prompts
If you want notes on your chats, timestamps and a prompt library in the same extension, GPT Master has those and Speed Booster Toolkit doesn’t.
Switching
Both change ChatGPT’s sidebar, so try one at a time: switch GPT Master off in your browser’s extensions page, then install Speed Booster Toolkit. Nothing on your ChatGPT account changes, and the first 7 days include Pro.
