What users say- REVIEW -

These comments were written in Japanese by their authors and translated automatically.

Since I started using OneComme, my stream screen suddenly got so much livelier and the comments became way easier to read! I'm active on TwitCasting + YouTube simultaneously, and I'm blown away every day by how usable OneComme is ✨ More and more first-time viewers tell me the comments are easy to join in on and that it's a fun stream, so I'm really glad I introduced it!

Above all, as an entry point, the initial setup is surprisingly easy, and the official site's setup guide is so thorough and kind 😊 Even people who aren't tech-savvy will probably think "oh, I can do this!" And on top of that, being able to do all this for free is just amazing~ 🐕️❤️❤️

There are so many fun updates too, thank you so much, OneComme 😆

I've been using this app ever since I first learned about OneComme! It's simple, yet it reaches all the spots that itch — it feels like it has basically every feature you'd want.

I stream from a Mac, so having proper Mac support is honestly such a huge help...!!

I have it set up to notify me with a sound when a viewer shows up, so I can notice even while I'm focused on gameplay — I think that's a lovely feature too. I'll keep using this app as an important partner supporting my streams going forward. I'm rooting for OneComme's service!!

The number one reason I started using OneComme is how easy it is to set up. Even without any knowledge of HTML/CSS, you can just drag and drop a comment box from a template that matches your image straight into OBS.

On top of that, it integrates easily with various text-to-speech services, so you can have comments read aloud in your ideal voice, which is also lovely.

Also, it's updated frequently and responds quickly even to YouTube's sudden spec changes, which is reassuring and makes me happy as a user.

As it stands, I can confidently say it's the number one comment support app in terms of the balance between features and ease of setup! Super recommended!

Since I do viewer participation streams, OneComme's viewer participation management feature comes in especially handy. Also, thanks to the viewer record feature, I can tell at a glance whether someone's a first-time viewer, which I'm very grateful for.

There are also lots of extra features, and the ability to customize things and the entertainment features that liven up the stream really let each streamer's personality shine, which I think is great.

There's no complicated operation or settings, so of course the barrier to entry is low, but the support system is also solid, and it keeps up with all sorts of platforms that are constantly evolving, which I appreciate too. I really hope people give it a try first and feel for themselves just how good "OneComme" is ♡"

  • You can record and take notes on viewers, so you can keep memories of them
  • WordParty lets you liven up the screen in a fun way → viewers love it too. The software is easy to read and easy to set up!
  • You can use all kinds of comment CSS. I use it all the time — I basically can't stream without OneComme.

OneComme is a highly capable comment text-to-speech tool that's usable by everyone from stream beginners to veterans. Setup is really easy, and the template editor's appeal is that once you've set it up, you can just drop it straight into OBS and it's instantly reflected.

Setting up comment text-to-speech is intuitive too, and the UI is simple and easy to read — it's the perfect tool for anyone who wants to build a comfortable streaming environment.

When I do viewer participation game streams, sometimes a participant's YouTube account name and their in-game name are different. Honestly it's hard to remember everyone, but since there's a memo field for each viewer, I can jot down their in-game name there and smoothly invite them the next time they show up, which is a huge help.

Also, I especially love the feature where typing a certain comment makes a set emoji fly across the screen. Since I like drinking, I set it up so that typing "cheers" or "KP" makes drinks fly across the screen. It gives me a real sense of connection with viewers on the other side of the screen — it's not just convenient, it's fun.

I also think it's great that there are comment box templates, and that there are so many customization options, including ones sold by volunteer creators. I'll keep using it going forward!

I got interested in making templates for OneComme and that's how I started using the software. With the comment tester, I can adjust the look of various patterns — like testing Super Chat or membership comments — without even accessing a live stream, which is a huge help. With its rich platform support, minimal missed comments, and the ability to set nicknames for viewers, I felt it was really easy to use even from a streamer's perspective.

The response when bugs occur or when requesting new features is also very kind, and it keeps evolving to be easier to use day by day. Thank you for always pursuing ease of use from the user's point of view. I'll keep using it with love from now on too!!

I use OneComme for grabbing comments and adding effects on my YouTube streams! The ease of just swapping the link to have it show up instantly in OBS is the best, and it's always such a help.

The UI is clean and easy to read, so I could use it right away even as a first-timer, which put me at ease. I can also set up animated effects for member-only stamps or specific words, and viewers love it! During singing streams, the effects react to comments, so everyone gets hyped up together and it creates a great sense of unity.

Even though it's basically free, the paid WordParty toss animations are wonderfully unique and super fun, and they've been a huge hit even in our quirky singing-stream relays!

It's been almost 2 years since I started using OneComme. Being able to tell "is this a first-time viewer or not," which I couldn't before, is such a huge help. People who've just changed their display name are still recognized as the same account, and I can check all their past names too, so it's hard for "fake first-timers" to slip through.

Also, total comment counts get accumulated and listed, so I love that I can visualize who comments a lot.

And above all, I think the standout feature is "WordParty," which lets you trigger specific effects from words viewers send, letting you really liven up the stream. It's fun every day thinking about how to set up effects that feel true to my channel.

I plan to keep using it going forward.

Actually, I recently commissioned custom comment CSS for OneComme for the first time, and I'm here to report it was a huge success ◎ I'm now streaming with a fun, cute original comment box ✨️

For chat streams, the customized liveliness helps a lot, and for FPS streams, it makes managing viewer participation really easy.

Thanks for always livening up my streams!!

It's been over 3 years since I started using OneComme. Back then, I was trying all sorts of things to get images to appear in sync with stream comments. I was stuck and at a loss when I discovered OneComme. I was able to easily implement it with a feature called WordParty!

I've been using it ever since. It just keeps getting more convenient — editing templates is easy, and it even saves viewers' past names, so it's so useful I can't do without it. You can start using it for free, so give it a try!

Even when a streaming site suddenly changes its specs, OneComme responds quickly, cutting down on those "wait, I'm about to stream and the comment box looks weird...!!" moments. That's the kind of powerhouse tool OneComme is.

It's also great ◎ that people using YouTube and people using Twitch can use the exact same CSS.
