ChatGPT - Pros & Cons
Pros
- ✓Most widely used AI assistant with the largest ecosystem of Custom GPTs, integrations, and third-party extensions
- ✓Six pricing tiers from free to enterprise provide options for every user profile and budget
- ✓Codex integration turns ChatGPT from a chat assistant into a software engineering platform that handles multi-file coding tasks autonomously
- ✓Meaningful free tier with GPT-4o mini access competes with paid tiers on simpler platforms
- ✓File Library and Google Drive integration make it easy to work with documents across conversations without re-uploading
- ✓Canvas mode enables collaborative document and code editing beyond chat-style back-and-forth
- ✓Deep Research capability produces comprehensive multi-source reports that would take hours of manual research
- ✓Mobile apps for iOS and Android with voice input, camera, and full feature access
Cons
- ✗Can hallucinate facts, especially on niche or very recent topics — verification against primary sources remains essential
- ✗Steep price jump between Plus ($20/month) and Pro ($200/month) with no intermediate option
- ✗Usage limits vary by plan and can change based on demand — specific message counts are not guaranteed long-term
- ✗Web browsing is inconsistent — sometimes fails to load pages, returns stale cached results, or misinterprets page content
- ✗Data used for model training on individual plans (Free, Go, Plus, Pro) by default — opt-out is available but not prominently surfaced
- ✗Custom GPTs vary wildly in quality — the GPT Store lacks effective curation, making it hard to find reliable ones
