| Tool | Best for | Price from | Free plan | Score | ||
|---|---|---|---|---|---|---|
| 1 | A small team that wants a dedicated answer bot trained on existing documentation, and is willing to test accuracy against its own content before paying | $49/mo | Yes | 4.1/5 | Visit | |
| 2 | Small teams with one or two writers and a public or gated help center that wants AI search and drafting included from the cheapest paid tier | $100/mo | No | 4.5/5 | Review | |
| 3 | Small teams already living in Slack that want AI-answered questions inside the channel they already use, without an upsell to unlock it | $8/user/mo | No | 4.4/5 | Review | |
| 4 | Small internal teams that want a real free wiki today and are willing to pay for AI search once they outgrow it | $6.67/user/mo (Startup, billed annually) | Yes | 4.0/5 | Review | |
| 5 | Small teams running a public help center that want AI drafting and an "Ask AI" feature included from the first paid tier | $129/mo (Sprout) | No | 3.9/5 | Review | |
| 6 | Teams that want a mature, heavily reviewed knowledge base and are planning to pay for AI from the start, not bolt it on later | $249/mo (Knowledge Base, no AI) | No | 3.8/5 | Review |
