In the world of AI assistants and productivity tools, Sider.ai has emerged as a popular all-in-one sidebar AI that promises to supercharge reading, writing, summarization, and research — plus rewards affiliates for promoting it. But is it actually worth your time as a user and as an affiliate?

What Is Sider.ai? (Tool Overview)
