• (2025-09-16) Adora Cortez: New layout sucks. Also, why is most stuff behind a paywall? I get that I don't use most of that stuff other than memory manager, but still.
• (2025-09-16) Jazu Graves: Holy paywall bromosapien
• (2025-09-16) Guest: I loved this extension, but the new layout is confusing to me. I'm having problems uploading my previous memory manager settings to the new design. Not a fan of the update.
• (2025-09-16) mapic: new update completely ruined the extension, was perfect before and now everything's locked behind a paywall and much shittier to use
• (2025-09-16) mr fish: new update is bad, i literally cant use half the stuff i used to. avatar sizes is locked behind a paywall (no surprise there tbh) and so is the message background (???) why those two of all things? all they do is customise stuff but no apparently I'm not allowed to have cool colours and actually visible avatar pictures. new update sucks, fix your extension.
• (2025-09-15) Gl1tch: I agree with Natalia and KittyWolfie and everyone else hating on this update, they ruined the extension, I don't even use any other feature besides the big icons, locking that behind a $5/month paywall is ridiculous, absolutely greedy and honestly, saddening, Developer, if you see this, just know, I really like this extension, please, return it back to how it was before, or at least make the avatar size feature free, Thank you.
• (2025-09-15) Natalia Nowaczyńska: Used to be great, now it's meh at best. Sure, I appreciate the effort, but the avatars are literally tiny now. In fact, they are 1/4th of the chatbox's size, instead of the usual, bigger one. Even disabling the extension and reloading the website doesn't fix the issue.
• (2025-09-15) KittyWolfie: It was good before, but the update kind of ruined everything. I just want my big icons :(
• (2025-09-15) Basking Crow: Previous free features are now paywalled without warning. I mostly used this for icon sizes and now its gone along with any other accessibility feature.
• (2025-09-15) kawa gulsever: hated the avatar thingy being behind a paywall, i mean the avatar size thing is the only thing i use for this. and you made it behind a bad paywall, but i support this decision if things are going rough.
• (2025-09-15) Jaxolon333: worst update ever, they locked the only features i use this extension for, that being to make the bot and my pfp's bigger on the chats, while also changing the color of the chat bubbles, i use that so i can better differentiate which message is mine and which one the bot's, like how the app does it. i understand locking the cosmetic features behind a paywall (like you said in response to another review), like custom fonts, text color and custom backgrounds, but this is too far, i don't care about all of the previously paywalled features becoming free, i wasn't gonna use them anyway, i just wanted to be able to see the pfps and text bubbles better
• (2025-09-15) J.J Banana: Great extension, but after this update I'm having trouble downloading the bots' json, has this function been removed?
• (2025-09-15) lixvzy: The only thing I use from CAI Tools is the avatar size tools, simple but they make it paid now L
• (2025-09-05) Karal “Just_karoşkiii” Afton: hersey premium aq
• (2025-09-02) Jaythe_0ne1241: BROOO I LOVED THE BIG AVATARS FEATURE FOR FREE, DONT PUT IT BEHIND A PAYWALL NOW. I UNDERSTAND IF YOU MAKE IT ALL ONE THING BUT TAKING AWAY FEATURES FOR FREE THAT YOU HAD FREE BEFORE IS WILDDD BRO
• (2025-07-20) P T: Thank you for the offline chat function. I've had so many RPs that was killing me to copy and paste one by one back into a word document (ON MOBILE), and this did what would have taken me weeks in less than five minutes. BLESS.
• (2025-07-16) Rz RaZeR 1930 (Germany): Giving it a solid 5 stars. The only issue is that it takes too much time to duplicate messages and the rest is completely fine It acts more like a life-saver because ca.i now shows "Too many messages to duplicate" (Not to mention there were 4201 messages) Editing: This is my first time use but i think they are creating too many shells, i mentioned only 200 shells but it created 4563 for what? (Still increasing)
• (2025-07-08) Quốc Hoàng: peak
• (2025-06-22) Matheo Sept: does not work
• (2025-06-09) Midas: it doesn't work for me. the blue box thingy doesn't appear... xd...
• (2025-05-15) Leyla Bello: It's literally everything I've been wanting as features for the app! It's a lifesaver, honestly!
• (2025-05-02) krish patel: Good extension but I just have a few questions. I tried to clone one chat of mine with has around 8400 messages. I clicked on "This conversation"-->"Create Duplicate"--> and I chose the "New version" in the cloning menu. And it showed creating shell messages that went on for like 32K for 8400 messages and it is still going. Thankfully I still do have my chat log from history so I could access my chat again but was that a bug? Should I try with the "Old version"? Also, if I create a "private copy" of the public bot, is there any way I can also transfer my chat history with that bot from the public one to private one?
• (2025-04-27) Manasseh: when i type in a memory it saves it but i want it to remember when me and the charater talks, but i have to type it first then talk to it, thats how i got it to remember, Plus, is there a way to stop the beeps before and after the charater speaks?
• (2025-04-26) Mohammad Ibraheem: GOODt OF ALL! but When i just tried to use it, IT DIDNT APPEAR! Fix your extension or i will rate it to 1
• (2025-04-01) Vanessa Pang: Amazing extension. You've saved me so much time. But I noticed when I went to fetch history, it says 2 failed on this one bot but I checked and realized it did fetch all of it. I think the last two that failed are legacy chats. I tried fetching with bots that used to have legacy chats but it didn't work unfortunately, saying there's no chat history (bawling my eyes out from losing them).
• (2025-04-01) rvidi: Good extension, but my card doesnt count as valid so i cant buy premium and paypal blocked in my country(
• (2025-03-29) Nic Molina: you had save me so much time and stress, i was copying each text one by one. But this app made it possible to copy all in one, i love it.
• (2025-03-28) Tk Tarlos: I absolutely love this. Thank you so much. I was wondering though, if its possible you can add changing font size to free. I have a very strong prescription, I have bad eyesight due to being a premature baby. As a result, small font is very difficult to read. And on cai mobile, the font is really small. If you can't change the adjustable font size to free, that's okay. I was just wondering. Thank you for making this extension for us, much appreciated. 💜💜
• (2025-03-17) Danielle Amanda: please tell me how the heck do i use this (and u get a free cookie!1!11!)
• (2025-03-11) Joel: Amazing app but it seems like the "Import a Character" feature stopped working?
• (2025-03-05) Shiloh Prince: Export character doesn't work anymore.
• (2025-02-23) Ayanna Stokes: The memory manager seems to be not working for me despite working before.
• (2025-02-21) Nyght Nyght: Cai tools had an affair with my wife of 5 eons
• (2025-02-17) kirby pixel: The worst extension i ever had.
• (2025-02-06) Spicy chicken ramen boberstorn bomber (Extra hot ramen): There's an error with the Message BG colors in Utility, when I click it I'm able to type instead dragging the color wheel. Also, I also understand that you can't give everything for free but it just feels like an added cai plus instead of an extension—almost all of us used this extension for the backgrounds and colors since it was behind a paywall, now it's just like it but doubled. Please, just allow us to be able to change the colors.
• (2025-01-30) lynx or Asker: after the gift, i had no purpose for it.
• (2025-01-29) Helping Hand Foundation: amazing. period
• (2025-01-20) trikostomb (charles , charlie): i loved it! it makes my c.ai quite better than before, it's amazing! i also loved how i could change my background, but of course it got turned into premium. i dont get the point of it becoming premium, honestly- and its not just that that became premium! a bunch of my other favourite features of this extension became premium, so i really dont get the point of using this anymore ;/
• (2025-01-18) Admiral: It stopped downloading cards for me, not sure why. Still keeping it at five because the plugin actually is good when that doesn't happen. I tested other functions though, I can still export chats. I press the buttons that don't work, and I get no response from attempting to download the png or json.
• (2025-01-17) Lily Minor: literally useless after the gift wares off... its best to just get a font changer and copy n paste the bot links to a doc :(
• (2025-01-15) Wesley Vassey: Sadly another service has fallen to greed
• (2025-01-15) Gabriel Underwood: This would be good, if you didn't need to pay for certain features, I do like it. but, why must you pay for features like text color? and why would I pay for a background, if I wanted to pay for a background I'd pay for character Ai+ just saying I will only change this once I don't have to pay for features I could use to if i'd pay for c.ai+
• (2025-01-15) mapic: i used this extension for the open dyslexic font so i could read character ai chats easier - now that font has been taken away from me bcs of premium
• (2025-01-15) Aleksandra Sinitsa (Ushastikoo): Damn, I idolized this extension, but now it's useless( Payment is inconvenient, and besides, I'm from Russia, I don't have the opportunity. Very sad...
• (2025-01-15) Reyna Ceja: I don't get it, its jan 15 do i have to pay for the bg features and everything else now??? I thought it would be free forever, could you please explain so I can understand better 😭😢
• (2025-01-13) Raspberry Rabbit: Amazing and everything works New background feature is so cool
• (2025-01-12) riri: it won't even activate?
• (2025-01-09) DarkAbyss LimboGirl: It helped me with what I wanted. It can't exactly work miracles like create of Character Copy of a bot that is deleted but the offline history fetching really was helpful in my own attempt to properly recreate the character.
• (2025-01-08) Tickler The: It's great. Character Card stopped working for me though. Is there a fix to that?
• (2025-01-02) Divoden: i love it im just confused on how the memory manager feature works tbh
