Strengths & Weaknesses
Deep Dive
Tettra delivers solid value at $4–$12/user/month for teams that genuinely only need an internal wiki with Slack Q&A. For a 20-person team, that's $80–$240/month—reasonable for what you get. Zendesk Guide offers exceptional power, but the $55–$249/agent/month price point includes a full ticketing platform you may never use. If your goal is documentation alone, Zendesk forces you to pay for ticketing infrastructure, routing logic, and agent tooling that adds zero value. For pure knowledge base use cases, Tettra wins on value. For support teams already on Zendesk, the bundled value is strong.
Tettra's per-user model scales linearly—a 100-person team on Scaling tier pays $800/month. That's predictable, but adds up. Zendesk's per-agent model scales painfully for support-heavy organizations. At 20 agents on Suite Professional ($115/agent), you're at $2,300/month before any AI add-ons. Add Autonomous AI Agents ($50/agent) and Agent Copilot ($50/agent) for all 20 agents, and costs jump to $4,300/month. For enterprises at Suite Enterprise Plus with AI, costs can exceed $350/agent/month. Tettra scales affordably for internal wikis; Zendesk scales cost-effectively only for teams deeply embedded in the Zendesk support ecosystem.
Tettra's hidden cost is what it can't do—no customer-facing portal, no video support, no multi-language documentation, no LMS. As your team grows and needs expand beyond internal Q&A, you'll need to bolt on additional tools. Zendesk's hidden costs are more literal—AI Agents and Agent Copilot are both $50/agent/month add-ons not included in any plan, and onboarding/professional services for complex deployments can add thousands. Both tools also share a critical gap—neither supports multi-tenant client portal delivery, making them unsuitable for agencies or consultancies serving multiple clients from a single documentation source.

Pricing Verdict
Our Recommendation
Tettra and Zendesk Guide serve fundamentally different buyers at opposite ends of the price spectrum. Tettra is an affordable, focused internal wiki for Slack-heavy teams that want simple knowledge sharing—nothing more, nothing less. Zendesk Guide is a premium customer support help center deeply embedded in a full ticketing platform, justifying its price only for teams that need both. If you need documentation beyond internal Q&A or support deflection, both tools leave significant gaps.
Choose Tettra if you need...
Choose Zendesk Guide if you need...
Choose Docsie if you need...
Winner: Docsie
Both Tettra and Zendesk Guide leave the same critical gaps—no video-to-documentation conversion, no multi-tenant client portal delivery, and no built-in LMS for training and certification. Tettra is locked to internal wikis; Zendesk Guide forces you to buy a full support suite for documentation. Docsie's AI credit model eliminates per-seat pricing inflation, its six-pillar platform covers CONVERT → MANAGE → DELIVER → LEARN → AUTOMATE → MONITOR in one system, and its multi-tenant architecture lets consultancies and enterprises serve unlimited clients from a single knowledge source—at a fraction of Zendesk's enterprise cost.
Common Questions
Q: Can I buy Zendesk Guide without purchasing the full Zendesk Suite?
A: No. Zendesk Guide is not sold as a standalone product. You must purchase a Zendesk Suite plan starting at $55/agent/month, which includes ticketing, messaging, and a full customer support platform. If you only need a knowledge base or help center without ticketing, you are paying for infrastructure you won't use. This makes Zendesk Guide a poor value for documentation-only use cases.
Q: How much does Tettra cost for a 50-person team?
A: On Tettra's Basic plan at $4/user/month, a 50-person team pays $200/month. On the Scaling plan ($8/user/month) that unlocks analytics and API access, costs rise to $400/month. On Professional ($12/user/month) with SSO and custom branding, the bill reaches $600/month. Pricing is predictable, but costs grow linearly with headcount and enterprise features are gated behind higher tiers.
Q: What are the hidden costs of Zendesk's AI features?
A: Zendesk's base Suite plans include only basic AI. Autonomous AI Agents—which automatically resolve tickets without human intervention—cost an additional $50/agent/month. Agent Copilot, which assists human agents, also costs $50/agent/month. For a 20-agent team on Suite Professional ($115/agent), adding both AI add-ons brings the total to $215/agent/month, or $4,300/month before any professional services or onboarding fees.
Q: Does Tettra have a free plan and is it worth using?
A: Yes. Tettra's free plan supports up to 10 users with basic knowledge base functionality and Slack integration. It is genuinely useful for very small teams exploring internal wiki tooling. However, it lacks AI features (Kai AI requires the $4/user Basic plan), analytics, API access, and SSO—so teams with more than 10 users or any enterprise requirements will need to upgrade quickly.
Q: Is there a better alternative to both Tettra and Zendesk Guide?
A: Yes—Docsie addresses the core limitations of both tools. Tettra is internal-only with no customer-facing portal, no video capabilities, and no multi-language support. Zendesk Guide forces you to pay for a full support suite even if you only need documentation. Docsie's workspace-based pricing ($199–$750/month for entire teams) includes video-to-documentation conversion, multi-tenant branded portals for multiple clients, 100+ language auto-translation, a built-in LMS, and enterprise compliance (SOC 2, HIPAA, GDPR)—all without per-seat fees or bundled products you don't need.
Q: Which tool is better for a company that needs both internal and customer-facing documentation?
A: Neither Tettra nor Zendesk Guide serves both use cases well. Tettra is strictly internal with no external publishing capability. Zendesk Guide is customer-facing but tied to a support ticketing platform and does not support multi-tenant client portals. Docsie is purpose-built for both—internal knowledge bases and multi-tenant external portals can be managed from one system, with granular content rules controlling what each audience sees.
Tettra caps you at internal-only wikis. Zendesk Guide charges $55–$249/agent/month for a support suite you may not need. Docsie converts your training videos and documents into multi-tenant branded portals, delivers to unlimited clients in 100+ languages, includes a built-in LMS with certifications, and costs a flat $199–$750/month for your entire team—no per-seat inflation, no bundled products you don't use.
Free plan includes AI credits to convert a 10-minute training video. No credit card required.
