Stop browser freezing and lag in long ChatGPT conversations. Instantly speeds up the entire UI and reduces memory usage.
Stop ChatGPT from freezing and lagging - in one click.
Speed Booster for ChatGPT makes huge conversations smooth again by rendering only a configurable number of messages at a time — no lost context, no data collection, no slowdown.
If you use ChatGPT for coding, writing, research, or long discussions, you know the problem: once a chat gets long, Chrome slows to a crawl, scrolling becomes jittery, and CPU usage spikes.
Speed Booster for ChatGPT solves this instantly.
🚀 What it does
Makes ChatGPT fast again — even in threads with 500+ messages — by rendering only the latest set of messages at first. You can configure exactly how many messages to keep visible!
Older messages are easily restored: just scroll up in your chat and press the "Load more messages" button. This keeps your full chat history accessible without the lag and without losing context.
✅ Why you’ll love it
- Smooth, zero-lag typing & scrolling — even in massive threads
- Lower CPU & memory usage — keeps Chrome fast and extends battery life
- No lost messages — your complete history stays intact
- Works automatically — install once and ChatGPT instantly feels faster
🔒 100% Privacy
All trimming logic runs entirely on your device, and your chat data never leaves your device.
No data collection, no tracking, no uploads, and no chat deletions — ever.
💎 Boost Your Workflow with PRO
While the free version is perfect for most, you can upgrade to PRO for a small one-time fee to unlock unlimited fast chats.
- No daily limits: Remove all daily usage limits on the lag-reduction engine for your longest conversations.
- Quiet Mode: Work in a completely clean interface by disabling all UI hints and notifications.
- Custom Thresholds: Gain full control over exactly how many messages are rendered at once to perfectly match your hardware's power.
- By buying PRO, you support the development.
When purchasing a PRO license, your license is securely managed by Freemius — a trusted payment platform. Your chat data is never involved.
🎁 A Special Thank You
As a huge thank you for being an early supporter and giving great feedback, the first 10,000 users across all browsers have been automatically upgraded to PRO for free for their current installations!
❤️ A Note from the Developer
This tool is specifically made to eliminate browser rendering lag (local slowdowns). While I cannot fix OpenAI’s server-side issues, this extension significantly optimizes how your device handles large chats.
Please note: I am a solo developer managing this project in my spare time alongside a full-time job. I do my best to keep the code updated and answer most important emails personally. I kindly ask for your patience and constructive feedback as I work to make the tool better for everyone and keep it working as long as possible. If this extension helps save you time, like it does for so many other people, please consider supporting the development by buying a PRO license - it makes a huge difference!
If you run into an issue, please contact me via [email protected] before leaving a negative review. Constructive feedback helps me make the tool better for everyone!
This extension is an independent project and is not affiliated with, endorsed by, or sponsored by OpenAI or ChatGPT.

- I bought the Pro version and within a few hours, my bank notified me of multiple fraudulent charges on my card. I believe it may have collected my data and transmitted it somewhere too. Beware. I should have known better.

- GOOD!
- Ray Browell
- This extension works as described. It is a very simple, easy to use product. If you don't like the cost, you can use it fro free, just buy the devloper a barley pop (option is in the app). And to be fair, the cost is not off putting at all! It is a fair price for a decent product. I am happy and I DO recommend.
- Jim Dollars
- Uhh.. why is this talking to external servers and asking me for money now?
- Just A Nerd
- works well, the chat stops lagging with big conversation i have big but here upon downloading the extension, users by default uses the pro version, after 7 days it will automatically revert to free version which limits 30 prompts only, ultimately defeat the purpose having to download the extension more over the premium plan is a $7.99, again $7.99 compare with a $8.99 go package with more features. its one time only yes but i find it very hard to pay for an extension with this amount especially when the extension only function is to remove the html codes.

- perfect

- It really works. Thanks!
- Colin K
- I regularly have really long, detailed conversations on ChatGPT (coding, research, deep dives, etc.), and this extension actually makes a difference. Responses feel faster and the experience is smoother during long sessions. If you’re someone who keeps big threads going instead of short one-off questions, you’ll notice it. Glad I got in early.
- Levi
- Just started using this and holy, this actually works! this is such a life saver
- hanzo
- I have a question and I'm just giving 5 stars for the benefit of the doubt, but does this extension affect the quality of how ChatGPT answers my questions? i.e. does speeding it up with this extension mean that ChatGPT puts less thought into my answers? I'm concerned about accuracy as I do a lot of intricate/high-precision work. Thanks.
- EDAM
- I had a few projects that I was working on simultaneously on different chats I even upgraded chatgpt to get longer conversations but it absolutely slowed down so much that I started to skip days where I didn't work on my projects at all . Finally I decided to do a search online for a solution and this extension came up. I downloaded it and opened a new chatgpt tab and loaded one of my longest chats. It worked like a charm!!!! THANK YOU!!!!!!!!!!
- Γιάννης Παύλου
- Excellent ! It reduced the history chat as result to consume less ram & to not be luggy. It exists the option to open the previous chat history if you need it which the addon has hidden dut to ram reason. Thanks !
- Hugo A.
- does it work on edge?
- Ali
- was working amazing until yesterday when it completely stopped working, hope it gets fixed since this is a lifesaver extension
- Chris Bigelow
- Finally!! When I get into a deep chat, Chrome just hangs and cannot cope. Solved it with this. 5 Stars.
- I Mean
- hey! I’m currently unable to afford the subscription Im broke ;(. I really appreciate the incredible work you’ve done as a solo developer—this extension is amazing and very useful for me. If possible, I would be very grateful if you could consider giving me Pro access. Thank you for your time and effort.
- Andriani Gkartzonika
- At first it was working great. But then, suddenly my chats that are part of a Project are not affected by this at all. The whole chat history loads and are very very slow and laggy. Please fix this! Otherwise, this is great.
- Jon Fisher
- Super useful!
- Stefanko C
- really good at reducing lag
- Jean
- Been using it for a while now. Also become a PRO user for free as I was one of the early users. Great stuff. Love it. Hats off to the dev.
- Penny Lane
- Worked flawlessly until today. Now it's like the booster isn't even installed, even though it is still showing as installed and active. Hopefully there will be some kind of update to correct it.
- Remedie X
- Straight to the point and actually works. Went from very laggy typing in a long chat to smooth typing and responses again. Wish I knew about it sooner.
- Noah Martin
- Absolutely amazing product, It was really annoying when chatGPT was getting slow in my long project chats. I'm an app-developer myself and was looking at using AI for long projects and this was one of the biggest issues I was facing. Also I'm so glad I got the PRO version for free, thanks very much dev. BTW I'm not a web developer so I'm not sure if this will be helpful but each message is contained in an article tag and the data-testid attribute always starts with "conversation-turn-" regardless of updates, I remember it was the same before so when you delete the messages from the DOM instead of selecting on the basis of class names maybe select on the basis of that attribute.
- Hans Bauer
- ive already loved this extension for a long time, absolute lifesaver, but what do you mean i get the PRO version for free?! absolute GOAT dev here, W

- Mike Johnston

- Aisha Meneses
- I can use my long session chats now without waiting 5 minutes in between messages and having my writing lag behind. Thank you so much for this !
- Gustavo P
- Great tool to use GPT without lag.
- Chaiyasak Aiyarapaisan
- It's the best tool.
- Ghali
- Started now to squeeze out money. A popup is forcing you to accept new termin accept new rights otherwise it stops - it went straigth to scam.
- itay200
- i got a free pro plan for being one of the first 10k people to use the extension. W dev
- S
- why are you sending to your api on every chat? i looked into network and it seems to be sending data it doesnt seem to be going to freemius dns?
- Michael
- Unfortunately have to stop the extension when generating images now that I got the free pro version. It wont generate any of the images past or present when I open the chat. This is a huge issue for me at the moment, if this gets fixed its a 5 star as it WAS doing what I wanted but the upgrade and update messed it up for me currently
- Scott
- This thing works miracles with reducing lag. just be careful because it works so well you don't know when you run out of memory in the chat!
- Rafael Cedeno
- Works great! If plugin is ON and ChatGPT is generating an answer, try not to hit refresh, sometimes it truncates the response, and have to refresh or close/re-open tab.
- Kyopsis23 K
- Yes, Yes, and more Yes It makes long sessions actually usable again!
- Dimitri Harkonen
- This works like a charm. This is EXACTLY what I needed at this time!!!
- Mister Peanut
- Simply the best! Thank you reddit guy. I never expected to make my long chats usable again from a random post on neckbeard heaven.
- neejohnenjegek Kiv
- It works great
- Thijs van Haveren
- This has completely changed my ChatGPT workflow. Thank you so much! Makes my life so much easier.
- Shane Burton
- Do NOT listen to the negative reviews.. THIS EXTENSTION IS PERFECTL! THANK YOU!!! The developer has been very generous, and still kept it FREE!! If you use it a lot every day, he is asking for a very small one-time fee, which is fair enough.. And still some people think others should just build software for them for free.. My god, the entitlement is real! KEEP UP THE AMAZING WORK! THIS EXTENSION IS THE BEST!
- M L
- BE CAREFUL. The extension has been updated, and the developer is sending something to their server and is clearly collecting some information.
- Tom
- It was a great start. But the author decided to cash in on users and made the functionality paid. It's a good thing I saved the first version, which chatgpt made many improvements to. All that's left is to publish it to GitHub. Greed is a sin.
- abdul basith
- the best
- Johannes
- What a life saver. It is not super convenient, to click the button to reload old messages, but it keeps my chats from freezing and I don't have to wait any more.
