Common Questions
Q: How much does ReadMe actually cost for a team that wants AI features?
A: ReadMe's AI features—the Agent Owlbert suite including doc linting, Ask AI search, and docs auditing—are only available on the Business plan at $349/month. The Startup plan at $79/month includes no AI whatsoever. Review workflows and SSO are also Business-tier features, meaning most teams end up paying $349/month regardless of their initial plan choice. There is no free trial to test AI features before committing.
Q: Is Tettra's per-user pricing competitive at scale?
A: Tettra is genuinely affordable for small teams—$4/user/month for the Basic tier with Kai AI included is hard to beat. However, the math changes quickly at scale. A 50-person team pays $200–$600/month on Tettra, and organizations needing SSO and custom branding pay $12/user/month ($600/month for 50 users). By comparison, Docsie's Organization plan at $750/month covers 90 users with SSO, analytics, and advanced features already included—often making it cheaper per user at mid-size.
Q: Does ReadMe charge per user or per project?
A: ReadMe charges a flat monthly fee per account tier rather than per user—the Startup, Business, and Enterprise plans are fixed-price regardless of how many team members access the platform (within limits). This makes ReadMe's pricing model attractive for larger developer teams where per-seat costs would otherwise balloon, but it also means the feature gating between Startup ($79/month) and Business ($349/month) is the primary cost driver rather than headcount.
Q: What hidden costs should I watch for with ReadMe and Tettra?
A: With ReadMe, the main hidden cost is the mandatory upgrade to Business ($349/month) once teams discover that SSO, AI features, analytics, and review workflows are all gated there—making the $79/month Startup plan a limited entry point for most production use cases. With Tettra, the hidden cost is custom branding and SSO both requiring the $12/user/month Professional tier, tripling the base price. Neither tool has transparent credit-based or consumption-based pricing—you pay for the tier regardless of actual usage.
Q: Can ReadMe be used as an internal knowledge base like Tettra?
A: ReadMe is specifically designed for external, developer-facing API documentation portals and is not well-suited as an internal team wiki. It lacks features like Slack Q&A integration, content verification workflows for internal teams, and the simple editing experience that makes Tettra effective for non-technical employees. Tettra, conversely, has no customer-facing capabilities whatsoever. These tools have essentially zero functional overlap—choose based on whether your primary need is external API docs (ReadMe) or internal team knowledge (Tettra).
Q: Is there a better alternative to both ReadMe and Tettra?
A: Yes—Docsie addresses the core limitations of both tools. ReadMe is exclusively for API documentation with no multi-tenant portals, no video conversion, and no multi-language support. Tettra is internal-only with no customer-facing delivery, no SOC 2 compliance, and no enterprise features. Docsie covers the full documentation lifecycle—converting training videos and PDFs into structured knowledge bases, delivering them through multi-tenant branded portals in 100+ languages, with a built-in LMS, autonomous agents, and real-time compliance monitoring for HIPAA, SOX, and GDPR. At $199–$750/month with AI credit-based pricing, Docsie often costs less than ReadMe's Business tier while doing significantly more.
Deep Dive
An in-depth analysis of how ReadMe and Tettra price their core features, where hidden costs emerge, and what you're actually buying at each tier.
ReadMe's value proposition is strongest for developer-facing API portals where the interactive explorer and versioned hubs justify the $79/month Startup entry point. However, value deteriorates quickly—AI features and review workflows require the $349/month Business tier, a 4.4x price jump. Tettra delivers genuine value at $4/user/month with Kai AI included from the Basic tier, making it affordable for small internal teams. For a 20-person team, Tettra costs $80–$240/month versus ReadMe's $79–$349/month flat fee, depending on features needed. Neither tool offers compelling value for teams needing both internal and customer-facing documentation.
ReadMe's per-project pricing model is initially predictable, but the $3,000+/month Enterprise tier creates a steep cliff for growing companies. There is no graduated mid-tier between $349/month and $3,000+/month—teams either stay on Business or absorb a massive cost jump. Tettra's per-user model scales linearly, which is manageable at small sizes but becomes expensive for larger organizations. A 100-person company pays $400–$1,200/month on Tettra versus ReadMe's fixed $349–$3,000+ depending on features. Neither tool offers volume discounts or credit-based models that let organizations pay proportionally to actual usage.
ReadMe's most significant hidden cost is the feature gating strategy—SSO, AI, analytics, and review workflows all sit behind the $349/month Business plan, meaning most teams end up there regardless of initial Startup plan intentions. ReadMe also has no free trial, so evaluating AI features requires paying $349/month upfront. Tettra hides costs in its tier structure too—custom branding and SSO require the $12/user/month Professional plan, tripling the base $4/user cost. Both tools also lack capabilities that teams frequently discover they need after signing up: multi-language support, video documentation, customer-facing portals, and compliance monitoring are entirely absent from both platforms.
