Pick by the job
| If you mainly want… | Look at | Why |
|---|---|---|
| Research with sources you can check | Perplexity | Built around search answers with citations |
| Writing and long documents | Claude | Often chosen for long, careful writing and large documents |
| Tight links with Google apps | Gemini | Integrated with Google services |
| One general assistant with the widest set of features | ChatGPT | The broadest feature set: voice, images, many integrations |
A fair test in ten minutes
- Pick three real tasks you do weekly: something to write, something to summarise, something to look up.
- Give the identical prompt to each assistant, and note whether each one cites where its facts came from.
- Ask each a question you already know the answer to, and see which one admits uncertainty instead of guessing.
- Check the price for the usage you actually have — free tiers and limits change often.
