If you want a browser that's tightly integrated with popular messengers and social networks, Opera Browser is a good option. It's got built-in messengers for quick chat and integration with a range of social networks. It also comes with a free VPN, ad blocker and AI assistant, so it's a good all-purpose tool for getting things done and staying safe online.
Another top contender is Brave, which is designed to offer private and secure web browsing. It's got an integrated AI assistant and a strong VPN that protects your entire device. Brave blocks ads, trackers and cookies by default so you don't have to worry about distractions while you're browsing.
Texts is a messaging app that centralizes messages from services like iMessage, WhatsApp and Telegram into a single inbox. It's designed with privacy as a priority and has features like chat summaries, draft chat replies and scheduling. It's not a browser, but it's a useful tool for managing multiple chat apps.
If you want an AI assistant, Lunabot brings ChatGPT abilities into your browser, working with Chrome, Edge, Firefox and Arc browsers. It offers shortcuts and custom commands for translation, summarization and writing, and it can help you get more done with an interface that's built into your browser.
These options should meet your needs for a browser that's integrated with popular messengers and social media sites while offering other tools to help you get more done and stay better protected.
