The AI tools worth paying for.
Recommendations by business type and by team function, with the reasoning shown and the losers named.
Most tool round-ups are written to rank, not to help — every entry is a winner and nothing is ever ruled out. These are written the other way round: the point of a shortlist is what didn't make it.
What every entry carries
- What it's for
- Who it suits
- Who it doesn't
- Real monthly cost at a realistic seat count
- What it replaces
- What breaks when you scale
- The verdict

We don't take commission on anything we recommend. Prices and verdicts are dated — anything we haven't re-checked recently says so at the top.
