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 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!

- YAYYYYYYYYYYYYYY NOW I DON'T HAVE TO WAIT SO LONG AND LONG!!!!!!🔥🔥🔥🔥🔥🔥

- I guess I just paid $7.99 to delete my chats? What is going on? I've been using ChatGPT for the past few months to aid in my job search and everything is just gone now. Starting from square one again but I won't make the mistake of reinstalling this.
- Eike-Christian Cordemann
- I do NOT recommend it! It deletes the chat history, important chats just gone! In the extension it will force you to upgrade to "Pro" after 7 days trial, without Pro it will be useless. Also begging further to buy a "coffee". UNINSTALLED and reported!
- Jan Hudák
- This is some incredible work. Thank you
- Rachel Jake
- Seeing the same issue as other reviewers. This used to work well but as of the last few days, It's been deleting messages. I would recommend disabling or uninstalling until there's a fix to address this but I will probably not trust this one again. Some very important conversations are now permanently gone.
- Mayuresh Indapurkar (Max)
- There is a bug in the app. It does not save current conversations. If I reload my chat, all my conversations are lost. I 'm using chrome on a Windows 11 machine. This is a serious issue and makes the extension unusable.
- Jae Love
- seems good so far. I use chatgpt for coding and after a few hours my chat windows would get laggy, long load times and it was frustrating to deal with. I found this from a reddit post. I noticed a lot of improvement on my load times. , it comes with a 7 day trial period which is nice and then limited use after for free. I found it helpful so I Just purchased it. thanks for the extension it has really increased my work flow.
- Aakash Gupta
- works like a charm
- MakaVelli
- Awesome extension,makes my chats so much faster and does not forget any history in chat (unlike other extensions who delete history....). Definitely my go to extension for context-rich chatgpt chats.
- Ahraz Ahmad
- amazing
- Leticia Gomez
- is good for chat
- howardzhuang
- Instantly boosted the speed of my ChatGPT browsing/workflow. I literally don't get that delay when I try to type anymore, or adding/attaching new files where you would click the UI and it would register 10 SECONDS later. Great extension! (P.S - I am university student, so I am always uploading dozens of pages/documents into my chats - my current setting is on 8 messages rendered, works for me the best. *The lower the # the better - I optimized it to be the fastest possible for my workflow.*) WILL BE GETTING PRO VERSION AFTER THIS 7 DAY TRIAL ENDS!
- Siv
- Doesn't work in all instances. Seems like it's not intergrated properly with all ChatGPT features in chat. Lost chat messages.
- Adam Camerer
- Extension works excellently. I was one of the first 10,000 users and got pro for free. One bug I have discovered is that, for some reason, messages do not 'automatically' get hidden as I continue a chatgpt session. However, when I refresh, the extension reduces the amount shown to the number selected. Its not a serious issue but a moderate inconvenience to have to refresh my chat every so often to 'trim' the number of messages down
- Amr Yasser
- works amazing, i had an unusable chatgpt tab as it was VERY long, and this solved it
- Arvind Raghav G
- works really well, ig ur idea of rendering a coupla messages at a time is pretty smart, lol. Lightsession is abolute BS compared to this cuz I didnt expect that extension to actually DELETE all my previous chats which were pretty important. I found that 30 messages a day works fine for me even tho i use chatgpt a lot. Ill consider upgrading to pro later, if i need it. BTW, dont listen to the haters I dont mind you putting a small fee, its not wrong to charge anyone 8 dollars for a service.
- Jay Shin (Jay)
- It does its job well; for sure it fails sometimes but it does eventually work after a few days. I do think the developer is genuinely working with issues real-time. The only thing I'm unhappy with is that while I got the free PRO version for being an early user, it only applies for installations at that point so I have to pay later for newer devices. Not that I can't understand the decision, and a free benefit is still a free benefit, but it does feel unfortunate.
- Claudine Francois
- "LOAD PREVIOUS MESSAGES" button no longer working or visible. I bought the pro version for this feature
- Jason Chiu
- can't load previous messages, after the 3/17 chatgpt UI update.
- max
- Lmao why does this have a subscription
- Joseph Erwin
- Perfect app and not intrusive! I bought the pro version after it started working for me for a day. Sad that this has to be an extension and not part of the vanilla experience...
- Cadu Santos
- It works.
- jack
- Seems like someone just took ChatGPT Light Session and added a paywall? Not sure why I would use this over one of the many free open source options.
- KeeLo
- just purchased. good shiiiiii btw those 1 * review bomb attempts are pretty funny
- Blake Brinkley
- Great extension, ignore the haters. Fully intend to pay for the premium version. Keep up the good work!
- Ashajbfn Psiyfn
- Horrible extension, payment is forced after 7 days and it is no longer just a "buy me a beer" payment like the developer once promised. It does it's job (which is the bare minimum) then forces you to pay $8 for an extension after 30 daily prompts are over. Ridiculousss. Also, found this comment the dev left funny: > Due to the high volume of support emails and user requests daily, the Pro plan was a needed addition to the free offering. What a BS excuse to charge for something that doesn't need to be paid, dude made up the easiest reason ever to add a Pro Plan to his chrome extension, that costs the same as Netflix!! Use this free version I found instead of paying a greedy Vibe Coder : https://chromewebstore.google.com/detail/chatgpt-lightsession/fmomjhjnmgpknbabfpojgifokaibeoje (It's called ChatGPT light session)
- Gustavo Andretto
- The dev. added a daily usage limit to force users to buy the premium version. I'm uninstalling it because there are free and open-source alternatives.
- mohammad alsubaie
- you deserve more than 5 stars, this extension is a life saver, ChatGPT app is lagging and takes about 10 min to function on the job that im currently doing.. but using this tool, ChatGPT and function way faster lets say it takes max two mins and im doing heavy coding work. Thanks to the developer
- Muhammad Qasim
- You are an absolute star! Thank you.
- Antonio Carballo
- An absolute game-changer for a chat that has gotten progressively slow to the point that one is spending more time waiting than working. THANK YOU! I'm buying the PRO version. I don't need it but it is the least that I can do to help future development.
- 2003 LN6
- works, one-time purchase fee (rare in this day and age!)
- Scott Rose
- What a fantastic extension! It works great! ChatGPT is FINALLY usable again. That you for inventing this product!
- Ed C
- 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.
- 원더풀마왕
- 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
- Rich Terry
- 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!
