Bottom line
Which tool is worth the price?
For most teams building a customer-facing knowledge base, Document360 delivers the strongest combination of editor quality, analytics, and SEO controls — its per-project pricing is high but predictable.
For internal wikis on a tight budget, Notion's free tier and $10/user/month Plus plan are hard to beat. Slite is the better call for remote teams that want AI-powered search without the flexibility overhead.
KnowledgeOwl's flat $79/month pricing makes it the most cost-effective option for larger support teams who don't want per-user costs to scale.
