Which general AI assistant is worth paying for if you freelance or sell digital products? A side-by-side of published prices, free plans and the side hustles each suits best.
How we made this comparison: this is a research-based comparison compiled from official pricing pages, help docs and public documentation, checked on October 21–22, 2026. We did not run hands-on tests for this page. Prices exclude tax, may differ by country and change often — confirm on the official site before buying. Some links may later become affiliate links; that never changes the price you pay.

Pros and cons
ChatGPT
Best for: All-round drafting, brainstorming, images and Custom GPTs · Published price (USD): Go $8/mo · Plus $20/mo · Pro from $100/mo
- 👍 Pros: Huge feature set (files, images, voice, Custom GPTs) in one app
- 👎 Cons: Free tier is limited; output needs fact-checking
Claude
Best for: Long documents, careful editing and natural-sounding writing · Published price (USD): Pro $20/mo ($17/mo billed yearly) · Max from $100/mo
- 👍 Pros: Strong at long context, structure and tone
- 👎 Cons: Usage limits reset in 5-hour windows; fewer media features
Gemini
Best for: Google Workspace users, research and video generation · Published price (USD): Google AI Plus $4.99/mo · AI Pro $19.99/mo · Ultra from $99.99/mo
- 👍 Pros: Built into Gmail/Docs; Pro plan bundles 5 TB storage

Our take
All three have capable free tiers — test your real tasks on each first. ChatGPT is the most versatile (images, voice, Custom GPTs you can sell). Claude is a favourite for long-form writing and editing. Gemini is the value pick if you live in Google Workspace or need storage. Many freelancers pay for one and keep the others free.
