Apexkit vs Sider AI

Sider's tier structure with our AI depth.

Sider AI runs the same 5-tier ladder we do ($4/$6.70/$12.40/$16.70 + Free) but with about 10 tools. We took the same tier structure and built it around a much bigger tool surface — 100 vs 10. Same low entry price, more reasons to stay subscribed.

TL;DR

Sider AI: ChatGPT sidebar + AI tools. ($4.20-16.70/mo (5 tiers))

Things Sider AI still does better

We won't pretend we beat them on everything. Three honest wins for the competition:

  • Sider's Chrome sidebar is its biggest UX advantage today — it sits in every tab. Ours is a tab.
  • Their multi-model picker (GPT vs Claude vs Gemini per query) is on our roadmap but not yet shipped.
  • Sider is genuinely cheaper at the entry tier ($4.20 vs £7.99).
