About

In practice. What you can do with ChatGPT.

ChatGPT is a conversational AI assistant for writing, coding, analysis, and automation, available on web, desktop and mobile apps, and through a developer API. Paid tiers add custom GPTs, projects, scheduled tasks, and deep research runs on top of the free base model.

The free plan has no cost but limited usage and no flagship model access. Plus starts at $20/month and raises those limits with roughly 160 messages per 3 hours and about 25 deep research runs monthly. It suits an independent professional using AI assistance daily for client work, while Business ($20/seat/month annual) and a $200/month Pro tier serve teams or heavy users needing higher caps.

Practical uses

Use caseDraft and refine client deliverables (reports, proposals, emails) with the Plus plan's higher message quota and custom GPTs.

Against. What to plan for.

Message and deep-research quotas are still capped on Plus, not unlimited.
Flagship models are locked behind a paid plan; the free tier only gives a base model.

You use it less than once a month

Detailed comparisons

Our verdict. What to know about ChatGPT.

How the score breaks down

Added value

At $20/month, Plus unlocks custom GPTs, projects, scheduled tasks and deep research on top of the free base model, a clear step up for regular use without jumping straight to the $200/month Pro tier.

Simplicity

The free plan requires only signing up to start chatting immediately, with no setup or technical skill needed for a first useful result.

Fit for purpose

It delivers conversational AI assistance for writing, coding, and analysis as promised, though message and deep-research quotas on Plus mean heavy users still hit caps rather than unlimited use.

Performance

Spans a free base model up to the highest-usage Pro tier with the most capable models, custom GPTs, an API, and dedicated Business/Enterprise tiers, a wide range for the category.

Reversibility

Neutral score: whether conversation history, custom GPTs, or project data can be fully exported if a user leaves ChatGPT is not covered by the collected sources.

AI. What it changes for ChatGPT.

AI challenges it

Go further with AI

ChatGPT remains the reference generalist (writing, code, analysis, brainstorming), but specialized vertical tools (Claude for complex code, Perplexity for research, Midjourney for images) often outperform it on their specific task.

Can AI replace it?

Does ChatGPT challenge creative and writing jobs? Partly: it speeds up first drafts, but relevance, fact-checking, and brand voice remain human work. Verdict: ChatGPT augments the generalist user's productivity, without replacing vertical expertise.
