ChatGPT official site

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
