Common Questions
Q: Can Tettra be used for customer-facing documentation like HubSpot KB?
A: No. Tettra is strictly an internal knowledge base — it does not support public-facing documentation portals, custom domains, or external user access. HubSpot Knowledge Base is specifically designed for customer-facing self-service with a branded portal and custom domain. If you need to serve both internal teams and external customers, neither tool alone covers the full requirement.
Q: Does HubSpot Knowledge Base work without the full Service Hub subscription?
A: No. The HubSpot Knowledge Base feature is exclusively available on Service Hub Professional ($450/month for 5 seats minimum, billed annually) or Service Hub Enterprise ($1,500/month for 10 seats minimum). There is no standalone knowledge base product from HubSpot. Teams evaluating it purely for documentation will be paying for ticketing, SLA management, customer feedback surveys, and other Service Hub features they may not need.
Q: Which tool has better AI — HubSpot or Tettra?
A: Tettra's Kai AI is more purpose-built and practically useful for its use case — it answers questions in Slack, routes unanswered queries to experts, and converts answers into new KB articles. HubSpot's AI assistant is a basic writing aid for drafting articles. Neither tool offers AI-powered video conversion, autonomous content agents, or agentic search with tool calls. For teams wanting AI that actually reduces documentation creation effort, both tools are limited.
Q: Is there a better alternative to both HubSpot Knowledge Base and Tettra?
A: Yes — Docsie is designed precisely for teams that outgrow both tools. Where HubSpot KB is expensive and ecosystem-locked, Docsie offers purpose-built documentation starting at $199/month with no forced service suite. Where Tettra is internal-only, Docsie delivers to both internal teams and external customers through multi-tenant branded portals. Docsie also adds capabilities neither competitor has — video-to-docs AI conversion, 100+ language auto-translation, built-in LMS with certifications, autonomous agents, and real-time compliance monitoring for HIPAA, SOX, ITAR, and GDPR.
Q: How does Tettra's pricing compare to HubSpot Knowledge Base at scale?
A: The difference is dramatic. A 50-person team on Tettra's Scaling plan pays $400/month ($8/user). The same team accessing HubSpot Knowledge Base through Service Hub Professional would pay $5,000/month ($100/seat). HubSpot's price reflects its full service suite — ticketing, SLA management, customer portal, and CRM — not just the KB. Teams that only need documentation will find HubSpot's pricing hard to justify unless they are actively using the broader Service Hub platform.
Q: Which tool is better for a team already using Slack heavily?
A: Tettra wins clearly for Slack-heavy internal teams. Its Kai AI integration means employees never have to leave Slack to find answers — the bot searches the knowledge base and responds in-thread, routes unknown questions to experts, and can publish new articles from conversations. HubSpot has a basic Slack integration for notifications but does not offer anything comparable to Tettra's embedded Q&A experience within Slack channels and direct messages.
Deep Dive
An in-depth analysis of how these two tools differ across use case fit, AI capabilities, enterprise readiness, and pricing value — to help you make the right decision.
HubSpot Knowledge Base and Tettra serve fundamentally different audiences. HubSpot KB is designed for customer-facing self-service — articles live on a branded portal, tie into CRM records, and help support teams deflect tickets. Tettra is strictly internal — teams use it to document processes, onboarding guides, and institutional knowledge shared through Slack. If your primary need is customer support deflection, HubSpot wins. If your goal is reducing repetitive internal questions, Tettra wins. Neither tool handles both audiences simultaneously, and neither supports multi-tenant delivery to multiple external clients from a single system.
Tettra's Kai AI is genuinely useful for internal teams — it answers questions directly in Slack by searching your knowledge base, reducing context-switching. It also routes unanswered questions to the right expert and turns responses into new KB articles. HubSpot's AI assistant is more basic — primarily a writing assistant for drafting and editing articles, not an intelligent Q&A engine. Neither tool offers AI-powered video-to-documentation conversion, autonomous content pipelines, or agentic search with tool calls. Teams expecting serious AI-driven knowledge automation will find both tools fall short of modern knowledge orchestration platforms.
HubSpot has a meaningful enterprise security posture — SOC 2 certified, GDPR compliant, EU data residency, 99.99% uptime SLA, and audit logs on Enterprise. However, SSO requires the Enterprise tier at $1,500/month minimum, and HIPAA compliance is not available. Tettra offers GDPR compliance but lacks SOC 2 certification entirely, has no published uptime SLA, no audit logs at any tier, and no data residency options. For regulated industries — healthcare, financial services, government — Tettra's compliance profile is a hard blocker. HubSpot's compliance is solid but the cost to access it is steep. Neither tool offers HIPAA-ready infrastructure or real-time compliance monitoring.
Tettra's pricing is genuinely accessible — free for teams up to 10, $4/user/month for the Basic plan with Kai AI and Slack integration, scaling to $12/user/month for SSO and custom branding. A 50-person team on Scaling pays $400/month. HubSpot's knowledge base, by contrast, is not available at any price below $450/month (5 seats on Service Hub Professional). A 50-person team on Service Hub Professional would pay $5,000/month. The pricing gap is enormous — but so is the use case gap. HubSpot is a full service platform; Tettra is a focused internal wiki. Buyers should evaluate what percentage of HubSpot's $450/month floor they're actually using, versus Tettra's narrow but well-executed feature set.
