ChatGPT review: still the default AI assistant in 2026
After a year of daily use across research, writing, and code, ChatGPT remains the most well-rounded assistant — even as rivals close the gap.
ChatGPT is still the assistant we open first. GPT-5.5 is genuinely better at multi-step reasoning, the voice mode finally feels conversational, and the ecosystem of custom GPTs and connectors is unmatched. It's not the cheapest and it's not always the most accurate, but it's the safest default for most people.

Pros & cons
PROS
- Best-in-class reasoning on GPT-5.5
- Excellent voice + multimodal flow
- Huge custom GPT / connector ecosystem
- Reliable code interpreter for data work
- Mobile + desktop apps both solid
CONS
- $20/mo Plus still feels limited at peak hours
- Hallucinates confidently on niche facts
- Memory feature leaks context between chats
- Image generation lags Midjourney
What we tested
We ran 30 days of daily prompts across research summaries, blog drafts, SQL debugging, and a 200-page PDF analysis. Plan: ChatGPT Plus ($20/mo).
Reasoning & accuracy
GPT-5.5 nails multi-step problems that tripped GPT-4 — tax math, contract review, multi-file refactors. On factual recall it still hallucinates ~8% of the time on obscure topics, so always verify citations.
Writing
Best tone control of any assistant we tested. The new style memory means it picks up your voice after 3-4 examples.
Code
Code Interpreter remains the killer feature for data work — upload a CSV, get charts and analysis in 20 seconds. For inline IDE coding, Cursor + Claude is still faster.
Pricing
- Free: GPT-5.5-mini, limited
- Plus $20/mo: full GPT-5.5, voice, image gen
- Pro $200/mo: o-series reasoning, longer context
Verdict
If you can only pay for one AI subscription, this is still it.
