much needed. Tysm dev

Amazing job, very thankful for this!

good job

As of today it works really well, really helpful for long sessions, thank you!

Insanely useful. You are an amazing person for making this. I have really long technical conversations with ChatGPT and dread the time when the convo's get to be too long, this saved me so much headache. THANK YOU

I've never seen an extension with a perfect 5/5 but it earned it. It does exactly what it says - I was honestly going to code my own if this wasn't already made. Reduced my nodes from 4896 down to 10.

Hit upon the exact issue - chats slowing to a crawl after long conversations with lots of code flying around - and immediately stumbled upon this solution, which works perfectly and exactly as advertised.

PERFECT!

Working and fixing the laggy chatgpt long conversations. Thank you for this solution.

First of all , Yeah this 100% worked , Chatgpt is really laggy in long conversations (Specially about me in programming) , This 101% fix it , And if your wondering how this has 5.0 stars , I guess cause this is actually good , And no im not a ##### bot , W devs , Ty for your help , Found it on a reddit page

works like a charm, thanks mate!

actually great, to anyone that said it doesnt work, it does. You just have to refresh your page. thats why it didnt work for me at first until i did that

fixed lagging/crashing chats with a long log of messages

Finally able to use ChatGPT again thanks to this extension.

Thank u so much. Very gooood

You are doing the lords work with this plug-in. Why ChatGPT cant do this themselves is beyond me. I really hope you continue to support this plug-in, because it saves a lot of time if you have a long session (to the point where without this plugin it is ridiculously laggy and time consuming). Thank you!

invaluable

Works like a charm! Thanks

Amazing! Thank you so much!

This extension is very helpful for those long, boring ChatGPT chats as it removes all the lag and makes ChatGPT much faster!

Perfect for those long and important ChatGPT chats, fixes the lag flawlessly, great product.

Like Magic - Game changer.

Bom demais da conta! Adiciona uma opção de doar pro projeto!

la mejor idea del mundo y funciona.

I had all but given up hope on ChatGPT. Personally I have project conversations to organize specific questions asked about that project, usually reincluding code snippets for it to focus on as I go, never expecting it to remember everything I've said in that conversation. I can understand the value of a continuing conversation that keeps everything in mind, however the ChatGPT frontend does not handle this functionality in a way that doesn't effect the UI functionality, resulting in incredibly laggy scrolling and text entry. Until they've sorted that issue out, this extension is a wonderful tool to have. Thanks so much!

Perfect

Awesome extension. It is exactly what I was looking for. Thanks.

Спасибо, гений

Thank you for developing this!!

You have brought back to life a chat with over 320 very long messages and responses. Brilliant! Thank you!

Maybe it should be updated, but currently it doesn't do anything.

Best Extension in 2025

This saved me HOURS of time

Exactly what it claims. Lightweight, fast, and privacy-first. I verified the permissions, reviewed the source code, and watched network traffic in DevTools. Everything runs locally in the browser, with no analytics, no tracking, and no third-party calls. It simply trims ChatGPT’s conversation data within your browser to keep sessions fast. Tiny footprint, no bloat, and it does one job well. If you use ChatGPT heavily and care about performance and privacy, this is a great extension.

Works best so far

This is working perfectly! I've had some very long chat session with ChatGPT refining some work. It would start to lag pretty quickly. I didn't want to start a new session because it would lose context. This fixed it. Even with long sessions, it doesn't feel like it's stuttering anymore. Thanks!

WOW you saved my behind today!!!!!!!!!!!!!!!! HIGHLY RECOMMEND THIS! Just install and refresh your GPT session. Last night sessions were taking 5 mins for responses on a 64gb ram computer.. crazy! Thanks for creating this.

Works! Long sessions are slow no more! My longest chat was starting to take many minutes at each turn of the chat, and after installing ChatGPT Lightsession, those turns are back to being measured in seconds. Thanks for this extension!!!!!!!

Outstanding performance improvements (I'm on Brave browser). Takes what would previously be literal minute delays between ChatGPT's response and the rendering on screen down to seconds, even in large context windows of hundreds of messages built up over several days. Why OpenAI haven't addressed this issue themselves is beyond me, but if they want to compete with Gemini, let's see what their GPT 5.2 can do when it (allegedly) comes out tomorrow (the 11th). Anyway, highly recommended for anyone struggling with longer conversations that require GPT's "Thinking" mode especially.

Such a good fix for a very frustrating problem! Thank you!

that work, thank you so much to do the work openAI should've done 2 years back

OMG! I've been having insane lag the last 6 days or so, to the point that ChatGPT is almost unusable. As a ChatGPT Business subscriber, I was starting to research which other LLM to switch to and planned to cancel my subscription after switching. This extension is the ONLY reason I did not did so. It has 100% fixed the problems I was having and I can now perform all ChatGPT functions I was doing this past week without any delay. WOW. OpenAI should buy this extension or at least give the author a sizable bug bounty for their efforts. Maybe they already have a fix and aren't releasing it until the next update or whatever. But even then, they would still be hemorrhaging users until that release happened regardless!

Works. great and indeed, it does dramatically increase the speed of the chat without slowing down texting ability or the processing time. Great extension, and I wish I had installed it sooner to save me the headaches.

game changing

works like a charm

best extension i have ever used

This made this the most usefull tool and fixed the bigest bug I couldn't recomend this more.

This extension immediately resolved the long-chat slowness problem. Absolute life-saver, and it works excellently. The only suggestion I'd have is to store the previous content in an accessible section of the page for searching previously mentioned content, but otherwise it's amazing :)

LIFE SAVER! THANK YOU!

Fixed immediately

Works perfectly, thank you!!
