Why Users Switch From Sider
Sider is a capable tool, but it has limitations that push users to look for alternatives. These are the most common pain points we hear from users who switched to Prophet.
Sider's subscription costs add up quickly even during months when you barely use AI assistance
Limited browser automation - Sider reads page text but cannot click buttons, fill forms, or navigate for you
Closed-source extension means you cannot verify what browsing data is collected or shared with third parties
How Prophet Solves These Problems
Prophet was designed from the ground up to address the gaps in existing browser AI tools. Here is how it tackles each pain point listed above.
Prophet's pay-per-use model charges only for the tokens you actually consume, so quiet months cost near zero
Prophet includes 18 browser automation tools that click, type, scroll, navigate, and manage tabs via Chrome DevTools Protocol
Prophet is fully open source on GitHub - audit the code yourself to verify exactly what data leaves your browser
