Yes. The Free plan includes one managed documentation site per workspace, pull-request previews, documentation analytics, unlimited pages and readers, all four output formats, and the MCP server. The engine is also open source under the MIT license and free to self-host forever. Thally Cloud adds three managed sites, AI answers, Track, custom domains, and team controls.

Everyone can search the docs or open an issue on GitHub. Cloud customers receive priority support, while Enterprise support and migration requirements are scoped with each customer.

Our team supports customers across US and EU business hours. Enterprise customers can arrange coverage and response commitments for production-critical issues.

We usually reply to sales and support messages within one business day. Enterprise response commitments depend on your support agreement.

Owners and Editors can invite teammates by email from the admin dashboard. Thally Cloud includes five team members in any role. Each additional active member or pending invitation adds $20 to the monthly bill.

Owner, Editor, and Viewer. Owners manage billing and workspace access, Editors write and publish, and Viewers get read access to private documentation.

Thally Cloud costs $199 per workspace per month, or the equivalent of $166 per month with $1,990 billed annually. Both include three managed sites, 10,000 shared monthly AI credits that roll over, unlimited connected product repositories, and five team members. Extra members are $20 per month or $200 per year, and extra sites are $39 per month or $390 per year.

Yes. A one-time $79 credit pack adds 10,000 AI credits to your workspace. Credits roll over while your subscription remains active, usage stops when the balance reaches zero, and packs never auto-recharge.

Yes. You can change or cancel your plan. Your docs remain in Git, so cancelling paid services does not take away your content or site source.

Thally is the product knowledge layer for software teams. It connects product changes to your docs, website, help center, and other customer-facing content, identifies what needs to change, and opens evidence-backed pull requests for your team to review.

Thally is a complete documentation platform, and it also keeps customer-facing knowledge aligned with the product. Track evaluates product changes, maps them to affected pages across your docs, website, and support content, and prepares evidence-backed updates for human review.

Thally can update your documentation site, including guides, API references, examples, and the changelog, plus connected customer-facing repositories such as your website and support content. Most teams start with docs and connect other surfaces as they go.

Yes. Thally optimizes for understanding before generation. If the available evidence does not show that a customer-facing page needs to change, Track can return a no-change result instead of producing unnecessary content.

Every page serves polished HTML for people plus JSON, JSON-LD, and Markdown for machines. All four formats come from one MDX source and the same URL.

⌘K hybrid search blends keyword and semantic matching over your indexed docs, returning instant results with inline previews and jump-to-section links.

Answers are retrieval-grounded: the engine only quotes your indexed docs and cites the exact pages inline. If the docs don't contain an answer, it says so rather than guessing.

Yes. Point Thally at an OpenAPI spec and it renders a fully typed reference with a live Try-It console, wired up automatically on every deploy.

Yes. Run the open-source engine wherever Next.js runs, including Vercel, Netlify, Cloudflare, Docker with the included Dockerfile, or a static export.

GitHub and Google sign-in are available today. Contact us to discuss enterprise identity and provisioning requirements for your organization.

Your content stays in your Git repo. Cloud processes only what's needed to serve and index your docs, and never trains models on your content.

Thally does not currently claim a public compliance certification or standard uptime SLA. Contact us with your security and procurement requirements so we can answer them directly.

Use Thally Cloud to migrate a public docs site, or run npx create-thally-docs migrate <your-repo-url> for a GitHub repository. Supported sources are converted to editable MDX in a Thally project.

If Thally is not the right fit within your first 30 days on a paid plan, contact our team to request a refund of your most recent payment. Enterprise agreements, misuse, and repeat subscriptions are excluded. Cancellations take effect at the end of the current billing period.

Thally's open-source engine is free for every project, including commercial use. Contact our team to discuss nonprofit or education pricing for managed services.

Open a discussion on GitHub or send a note to our team. We prioritize work that improves Thally's understanding of product changes, strengthens product-specific knowledge, reduces communication work, or keeps customer-facing knowledge synchronized.
