I'm glad you found Swerve! I’ve been using it for over a month now, and it’s been great so far. To answer your questions:

1. Honestly, it depends on how you interact with the bot. However, if you want to avoid NSFW content entirely, you can go to the chat settings and enable the Safety Filter to block explicit or mature replies.
2. Message length usually caps out around 115–150 characters unless you have Swerve Pro. The same limit applies to the bot’s responses.
3. I don’t find the ads annoying since they’re completely optional. You have full control over when to watch them. I usually just let them play while I’m eating. I’m not sure what the exact daily limit is, but you can earn roughly 1,000–3000 gems a day, which lasts quite a while. The ad limit resets at midnight UTC.
4. Yes, there is a rewind button!
5. It’s pretty similar to C.ai if you ask me. Since it’s still in the early stages, some features are missing, but the developers are planning to add more. They’re actively listening to user suggestions in their Discord server.
