The answer, as recorded

The honest answer splits in two, because "knowledge base" means two different products. Here's what I'd actually recommend, in order: ## If it's customer-facing (a public help center to deflect tickets) 1. **Help Scout** - my default pick for a small business. It's a help desk with Docs (the knowledge base) built in, so articles and the shared inbox live in one place, and pricing is by *contacts helped* rather than per seat - free up to 50 contacts/month with unlimited agents, then ~$50/mo Standard. That billing model is unusually kind to a small team with lots of part-time helpers. The tradeoff: the KB is deliberately simple, and gets limiting if you want deep article hierarchies. 2. **Freshdesk** - the value play if you want more structure. Entry tiers start around $7/agent/month, and the help center is more configurable than Help Scout's: category-level access control, labels, analytics, customer portals, and community forums. Choose this over Help Scout when you need organization and permissions more than simplicity. 3. **Zendesk Guide** - only if you're already on (or heading to) Zendesk. It isn't sold standalone; it rides along with Zendesk Suite from ~$55/agent/month. Excellent product, but you're buying a whole ticketing platform to get it. 4. **Intercom (now Fin)** - worth naming because of the pricing model, not the docs. Help desk from ~$29/seat/month, with the Fin AI agent billed at ~$0.99 per actual resolution. If your goal is "customers stop emailing us," paying per deflection is the cleanest alignment on this list. 5. **Document360 / Helpjuice** - the specialist tools. Helpjuice has the best search in the category (which matters more than anything else if your KB is large) but starts at ~$249/mo for 30 users, with AI on the $449 tier. Document360 dropped its free tier in late 2024 and now hides pricing behind sales. Both are usually overkill under ~20 people. ## If it's internal (a company wiki / SOPs / onboarding) 1. **Notion** - the pragmatic first choice. Everyone already knows it, adoption is near-zero-friction, and it doubles as your docs, project tracker, and CRM-ish thing. It gets messy at scale and Business runs ~$20/user, but for a small business that's rarely the binding constraint. 2. **Tettra** - best value if you want a *real* wiki rather than a doc pile. Roughly $4-5/user/month with a 10-user minimum, and the base plan includes AI Q&A and content verification (it nags owners to re-confirm stale pages). The Q&A-driven model - questions in Slack become articles - is the right shape for a small team. 3. **Nuclino** - around $5/user/month, fast and clean, blends wiki with light project management. Good middle ground between Notion's sprawl and Tettra's narrowness. 4. **Guru** - ~$10/user/month, 10-seat minimum, annual. Its edge is surfacing knowledge inside Slack and the browser where people already work. Pick it if your problem is that nobody *reads* the wiki. 5. **Slab** - ~$6.67/user/month annual, genuinely nice editor, but no AI, no API, no custom branding. Fine, just outclassed on value by Tettra now. **My one-line take:** small business, customer-facing → Help Scout; small business, internal → Notion if you want zero adoption friction, Tettra if you want the docs to actually stay accurate. The real failure mode isn't picking the wrong tool, it's picking one nobody updates - a stale KB deflects no tickets. Two caveats: the pricing above comes from 2026 comparison roundups rather than each vendor's own page, so confirm current numbers before you buy, and note that several of these sources are published by competing vendors and rank themselves favorably.
