You get most of the core features without paying anything, which is rare these days. We tested the free version extensively and found it works great for everyday use.
What we really like is that the free version doesn't feel like a limited trial. You can use it indefinitely without feeling like you're missing out on essential features.

| Security & Privacy Prod Apps's expert score for the 'Security & Privacy' aspect of each app. | 7.0 Security and privacy get a 7 out of 10 from us. The app uses standard security practices like encryption, which is good. The privacy policy is clear about what data they collect and how they use it. You have some control over your data:
However, some users have concerns about how much data is being collected for AI training. The privacy controls could be more detailed and easier to access. We'd like to see more options for users who want to limit data collection. Overall, it seems safe to use, but we'd recommend reading the privacy policy if you're concerned about data collection. Winner in this category | 7.0 For security and privacy, we give Merlin AI a 7 out of 10. The app uses standard encryption for your conversations and personal data, which is good. However, since it connects to multiple AI providers, your data might be shared with these third-party services. This is mentioned in their privacy policy, but it's something to be aware of. The app doesn't ask for unnecessary permissions, but remember that your conversations and any documents you upload are processed by external AI services. While the company is transparent about how they use data, we would have liked more control over what gets shared with which AI providers. They do a good job of being upfront about it, but some users might want more control over their data. Winner in this category | ||||
