Sider

An all-in-one AI service that started as a browser sidebar and now bundles GPT, Claude, Gemini and Grok chat, image and video generation, and a cloud computer agent

What is good

  • Very wide model lineup and quick to add the latest models
  • Rich tools such as ChatPDF, YouTube summaries, deep research and AI slides
  • Every plan includes every feature (the difference is the amount of credits)

What could be better

  • Prices rose sharply when plans were reorganized into Nano/Lite/Pro/Max in the second half of 2026 (Lite from $25 per third-party sources)
  • Deductions are based on actual token use, so they are hard to predict
