ChatGPT is OpenAI's conversational assistant: you type or speak a request and get text answers, generated images, file and data analysis, web-search results with citations, and multi-step deep research reports.
Our take: Start on Free (unlimited everyday text chat with GPT-5.6 Luna); move to Plus at $20/month when you need GPT-6 reasoning models, projects, scheduled tasks and higher tool limits.
Main limitation: Almost every tool (uploads, images, voice, deep research, Codex) has plan-dependent usage caps that OpenAI states can change over time, and the API is billed separately from every ChatGPT subscription.

Based on the vendor's official documentation; we have not tested this product hands-on. What “documented overview” means
Who ChatGPT fits
Start on Free (unlimited everyday text chat with GPT-5.6 Luna); move to Plus at $20/month when you need GPT-6 reasoning models, projects, scheduled tasks and higher tool limits. Based on the vendor's documentation, not on a hands-on test.
Best for: General writing, brainstorming, studying and everyday Q&A
Also a good fit for
Research with web search and cited deep-research reports
Analyzing uploaded files, spreadsheets and images
Teams needing a shared workspace with admin controls and no training on their data
Consider another tool if you need a plan-inclusive API (ChatGPT plans never include API usage)
Or if
You want predictable, published per-tool quotas (limits are described as varying with demand)
You want to build and publish custom GPTs on a personal plan (not available on Free/Go/Plus/Pro)
You need annual billing on an individual plan (only Business and Enterprise offer it)

What is ChatGPT, and how does it work?
ChatGPT is a conversational AI assistant that answers questions, drafts and rewrites text, reasons through problems, translates, analyzes uploaded files and images, generates images, searches the web with citations, runs code for data analysis and can execute multi-step agentic tasks (ChatGPT Work, Codex, dots).
