This is a follow-up to my earlier review and the author’s response. After months of use and testing, I wanted to share more detailed, updated feedback, especially regarding the plugin’s AI moderation feature, which is still the main selling point. I'm not here to dunk on the plugin or its developers, or to “get a refund,” but rather to address the glaring issues still present months after my first review. My server network team just passed a vote to completely remove this plugin and replace it with alternatives for the following reasons. It’s been a chore keeping the plugin working for our network and unfortunately has presented more problems than it has solved.

Regarding AI moderation and transparency: The core issue isn’t whether the AI "hallucinates" — it’s that there’s zero transparency. There are no public docs, logs, or debug output showing that OpenAI API calls are being made at all. The plugin JAR is obfuscated and the GitHub repo only includes YAML config files, so there’s no way for us to verify that OpenAI is actually involved. The core question is, how exactly is OpenAI integrated into the plugin? There are no options to specify model, temperature, or other settings. Only a “threshold” option, which is more aligned with keyword scanning than actual AI moderation. In real-world conditions, OpenAI API calls usually take 400 to 900 milliseconds, which makes real-time moderation for a busy server with 40 to 60 chat messages per burst nearly impossible without batching or caching — neither of which are documented. The performance hit we’re seeing feels far more consistent with traditional regex or keyword filtering than true LLM analysis. If no API calls are happening, then the AI branding and selling points are not just unclear — they’re misleading. These are facts, not “baseless” claims as stated by the author.

Performance is another major issue. AdvancedChat is significantly heavier than expected for a chat plugin. On our Paper 1.21.5, 1.21.6, and 1.21.7 servers, with averages of 50 to 120 concurrent players, it regularly accounts for 25 to 35 percent of total MSPT in timings and Spark reports, even with most features disabled. This has been getting gradually worse over time. That’s excessive, especially when compared to free alternatives like VentureChat or ChatControl, which stay under 1 millisecond. The developer claims it runs well on 200 to 300 player servers but hasn’t provided any profiling or benchmarking data to support that claim. I’m happy to provide Spark reports for each of our servers along with a detailed plugin list and player counts if that’s helpful.

Since my first review, updates have mostly been limited to community language files and minor bug fixes. There’s still no roadmap or changelog entry addressing AI transparency, performance optimization, or formatting flexibility.

To close, I just want to emphasize that buyers deserve to know exactly what they’re purchasing — especially when features like AI moderation are central to the plugin’s branding. My intention with this review isn’t to be negative, but to offer constructive feedback in the hope that it leads to improvements. I wouldn’t bother leaving this review if the plugin didn’t present a solid concept worth building on.

Had a few issues with the plugin once I got speaking to gc we were able to work them out features are good

Support team is like bots, glances over support requests and replies about something completely different also there isn't proper network support unless you run this plugin on every server on the network which is not do able in our case

Did give 3 stars originally but then the 12 year old on the support team just closed the ticket

To be honest, the features that I initially thought were good actually take up more resources than I thought. I think it's a really terrible plugin.

This plugin is good but i have a console problem and i cant verify myself with the same nicknane on disocrd so i cant have help, please...

Amazing plugin! It has every feature you expect from a chat plugin. The only suggestion I have is displaying the variable information into DiscordSRV chat channel.

However, i did see some config parts that are not beginner friendly and require a bit of time and knowledge to understand.

10/10!

"This is one of the worst premium plugins. When I was setting up an MC server, I decided to buy it, but it's absolutely trash—20 euros wasted for no reason. Placeholder handling in chat is overly complicated to set up, even though it could have been done completely differently, like the competition, which is even free. The overall feeling about this plugin is that it's unnecessarily complicated, not very stable—but then again, that's probably the case for all plugins from this guy. "

Absolutely the best chat plugin I've ever used! AdvancedChat completely transformed my server’s chat system with its powerful formatting options, AI moderation, and easy customization. The ability to edit any message from any plugin is a game-changer, and the auto-moderation keeps my server clean even when I'm offline. Chat bubbles and custom channels are fantastic additions that my players love. If you're serious about managing your server's chat, this is a must-have. Worth every penny!

⭐⭐⭐⭐⭐ Very Good Excellent Plugin From GC. I own all GC plugins and I love them all.

Good job team on support and updates!! Recommended to all

Sometimes I really wish there is a way to try before you buy.

I purchased AdvancedChat primarily for its AI-driven moderation capabilities, hoping it would provide a more robust and intelligent filtering system than free alternatives. Unfortunately, at its core, it doesn’t offer much beyond what existing free plugins already provide.

The AI moderation feature seems questionable—while it catches basic rule-breaking messages, more subtle or coded language, such as racist dog whistles and inappropriate jokes, often slip through. Even after tweaking the confidence thresholds, it’s unclear if OpenAI’s API is truly being used for analysis, as claimed. Without access to the actual source code (since only configuration YAML files are available in the repository), there’s no real transparency on how the plugin processes chat messages.

Performance-wise, I was disappointed. For what is essentially a chat moderation plugin, it isn’t as lightweight or optimized as I’d expect. Timings reports show it running fairly excessive tasks that contribute to higher MSPT, even with multiple features disabled. A chat plugin shouldn’t be impacting server performance this much.

Another minor frustration is the lack of an option to fully disable chat formatting. While customization is nice for some, it would be helpful to have a way to turn it off entirely without relying on additional plugins.

That said, AdvancedChat has potential. If future updates improve AI moderation, optimize performance, and increase transparency in its functionality, it could become a solid premium alternative to free options. As of now, though, it’s not quite there yet.

2/5 (Promising, but not worth it in its current state)

After playing around with this plugin for ten days, I wanted to make an honest review.

First off, the positives:
AdvancedChat is very easy to configure and super user friendly.
I've used ChatControl in the past, which can be super confusing for new server owners. This plugin is a lot better when it comes to being in a format that can be understood easily.
The automatic filtering and AI features make this plugin stand out from the competition, as they are worlds ahead.
I love that you can have some server links in the escape menu!
You can (for example) put your modpack there or have a link to your discord / website there.

My nitpicks are somewhat minor, but I still think they have to be addressed in order to deserve a full 5 star rating:
For me, the cross server chat things have not worked. At all.
I've reported the bug to GitHub and will update my review if the situation changes.
And as it stands right now, some features are still a bit lacking compared to the competition.
For example, the tags and chatcolor that you can choose (In a nice menu that you can quickly add things to btw!) do not stay with you if you choose to go to a different server in your network.

All in all, I can say that this is a really solid plugin with a bright future ahead!
If you want a singular plugin for all messages on your server, this will be it.

As a lot of others, the AI Moderation is top tier. it's the main selling point, and I have to agree. It's an amazing filter, the best one on the market. But the other features are kind of lacking.

After extensive testing on my 1.21.4 server, AdvancedChat has proven to be an exceptional addition.

STANDOUT FEATURES:
- AI-powered moderation is incredibly effective at maintaining chat quality
- Extensive formatting options with pre-made templates for different ranks
Cloud-based filter works really well with multi-language support
- Chat bubbles implementation without resource packs (super unique)

The plugin shines in its attention to detail - from the intuitive command creation system to the smart auto-announcements. The AI moderation particularly impresses, catching nuanced inappropriate content that traditional filters miss.

For server owners looking to modernize their chat system, this is currently the most comprehensive solution available. The regular updates and active development show strong commitment to the product.

A must-have for any serious server looking to elevate their chat experience. Very mcuh recommended!

Been waiting for almost 2 months for the plugin to work. It could be a good plugin but sadly the support does know nothing about the plugin. Github issue & Discord Ticket got closed for the reason "Will be fixed in the next update" it already has been 3 updates and almost 2 months. What a waste of money the cross-server feature is still bugged. Will update this review if the bugs will be fixed, which I doubt

a lot of warns for no reason a lot of warns for no reason a lot of warns for no reason a lot of warns for no reason

Had to restart the server 3 times to get it working but now its fine!
Great plugin!

This plugin does support cross-server chat, but there are many issues with its configuration. When I enable crossServer: true, it successfully synchronizes messages across multiple servers. However, when I rejoin the server, messages are duplicated. For example, if I say "1", it will appear twice as "1". I’ve been trying to get verified on Discord for a week now, but I haven't had any success, and no one has helped me. It makes me feel like the response and support are really inefficient. Based on my experience, I wouldn’t recommend buying this plugin.

AdvancedChat has been a solid addition to my Minecraft server. The chat formatting options are pretty extensive, letting me set up different styles for various ranks. I was skeptical about the AI moderation at first, but it's caught some inappropriate stuff that slipped past our usual filters. Creating custom commands is handy, though it took some getting used to. The auto-announcements feature saves me time on repetitive server messages. While it has a learning curve, overall AdvancedChat does what it says on the tin and has improved our server's chat experience.

An incredibly scary plugin. Do not give money to this plugin and do not throw your money in the trash. I have used other plugins of this developer, they are seamless. But this plugin is incredibly flawed. I've been waiting for weeks for an error to be resolved. They promised that it was solved every time, but it was never solved. There are too many errors in the plugin.

AdvancedChat is a game-changer for Minecraft servers. The AI-powered moderation catches things I never could, keeping chat clean without constant babysitting. Custom formatting makes our server feel unique, and being able to edit any in-game message is incredibly useful. The auto-moderation and custom commands have saved me countless hours of work. What really sets it apart is how well it plays with other plugins - it just fits right into our existing setup. If you're looking to upgrade your server's chat experience, this is the plugin to get.

Pretty packed full of features, performance works well. Just needs more updates addressing common issues and constant error console spam.

I use all Advanced plugins made by GC, very good plugins with high quality and good performance. Only recommend from me.

The plugin is okay, and if it were free, I would give it 4 or 5 stars. However, I encountered a few issues and was underwhelmed with its performance overall.

First I'll start with the good. One of the main reasons I bought this plugin was for a high-quality chat filter, and this plugin not only delivered, but it knocked it out of the park. The AI-Powered filter and the community swear filter manages to block pretty much every swear word that normal chat filters would, plus more phrases and sentences that normal chat filters would not. This feature alone is a 5/5.

However that's the only feature that really impressed me, and quite a few other features are not only mediocre and buggy, but can be outperformed by other free plugins. Yes, it's nice that all the features are packed into one plugin, but I personally would rather have 10 high-quality plugins than 1 substandard plugin (although that may not be the case for other customers). As an example, the chat games that this comes with aren't the greatest, and I ended up replacing it with another free plugin that works so much better.

Here is a list of bugs I experienced:
- Emojis don't work (Other players also reported this on GitHub)
- [item] doesn't work (Other players also reported this on GitHub)
- @Player mentions work half the time (No reports on github)
- The cool player head display upon player joining stopped working (Other players also reported this on GitHub)

While there are bugs and issues with this plugin, the main feature it advertises (chat moderation) excels, which is why I'm giving it a 3 and not a 1 or 2. If you are strictly looking for a good chat-filter, then buy this. If you want it for the extra features it has, don't but this.

Most excellent chat plugin. I recently came back and noticed other chat plugins being abandoned, and this one popped up on my radar - it's very well made.

Very well made with good AI integration! Definitely feels futuristic seeing the chat messages protected from nonsense and harrasement of other players. 10/10

It's a great plugin, but the support member Vision was not very helpful with Verification saying that I was required to show my receipt after providing the required proof in their rules (which is not the receipt). This was highly inconvenient for someone with hundreds of transactions across multiple Paypal accounts. After providing enough information Visions left the chat completely during a live conversation. I can understand why but this was just frustrating.

I rarely write reviews anywhere but this time I will just so you can improve your service. Thank you.

The plugin itself is somewhat decent. But as Network owner, turns out you need to PAY 10 EUR more to have more than one server works with the plugin. This makes the overall product cost 30EUR. This behavior is more than greedy. And this info is HIDDEN in the LAST "SPOLIER" of the terms of use.

NO other "premium" plugin does this. And I hope no one will do.
IP limit should be there to prevent distribution of the resource. Not preventing customers from using it.

has good features but chat filter obfuscate doesn't work at all so swear words don't get censored and chat filter AI is not very customizable ether

Me gustó muchísimo este plugin, vale la pena totalmente. Solo me gustaría que tuviera la integración con DISCORDSVR

I was just looking for the best modern chat plugin on spigot, and ofcourse right when i need it, mister GC goes on and creates one with features i all need. Thanks, i will report any bugs if i find one.

One of the best chat plugins I could find and staff were able to fix my issue that I was having with the plugin.

Seems like a good plugin but is not functional on my 1.19 server once my problem is fixed I will change review

Seems like a good plugin but I cant type in chat it just shows a list of permissions that I have whenever I type anything and I get this error in console

Excellent! Really impressed how they integrated AI into chats and been quick to respond to questions. Switched from CHC Red, killer features from AdvancedChat were the games and AI!

Keep on doing what ya'll are doing, guys. Excellente!
