# Frequently Asked Questions

## General

<AccordionGroup>
  <Accordion title="What is thig.ai?">
    thig.ai is an AI-powered platform for creating Product Requirements Documents (PRDs). You describe your product idea through a guided AI conversation, and the platform generates a professional PRD that you can edit, collaborate on, and export. See the [Introduction](/introduction) for a full overview.
  </Accordion>

  <Accordion title="How does the AI conversation work?">
    When you start a new project, you select a template and begin chatting with an AI assistant. The AI asks targeted questions about your product — goals, users, features, constraints — and uses your answers to generate a structured PRD. You can steer the conversation naturally, skip questions, or provide additional context at any time. Learn more in [AI Chat](/user-guide/ai-chat).
  </Accordion>

  <Accordion title="Which AI providers does thig.ai support?">
    thig.ai supports three AI providers: OpenAI (GPT), Anthropic (Claude), and Google Gemini. You can switch providers at any time or bring your own API keys to use your personal accounts. All providers are unified behind a single interface so the experience is consistent regardless of which one you choose.
  </Accordion>

  <Accordion title="Is my data secure?">
    Yes. All data is stored in a secure PostgreSQL database with row-level security. API keys are encrypted at rest using AES-256-GCM. Passwords are hashed with bcryptjs, and accounts lock after 5 failed login attempts. Rate limiting protects against brute-force attacks. Enterprise plans also get two-factor authentication (MFA), IP allowlisting, and comprehensive audit logs. See [Security](/user-guide/security) for more details.
  </Accordion>

  <Accordion title="Does thig.ai support two-factor authentication?">
    Yes. You can enable TOTP-based MFA from **Settings > Security**. Use any authenticator app (Google Authenticator, Authy, 1Password) to scan the QR code. You also receive 10 backup codes for recovery. See [Security](/user-guide/security#two-factor-authentication-mfa) for setup instructions.
  </Accordion>
</AccordionGroup>

## Accounts & Billing

<AccordionGroup>
  <Accordion title="What plans are available?">
    thig.ai offers four tiers: Free, Starter, Professional, and Enterprise. Each plan increases limits on team members, projects, AI tokens, templates, API keys, and exports. Starter and above unlock scheduled exports, REST API access, and additional integrations. Enterprise adds approval workflows, IP allowlisting, and unlimited resources. Visit the [Billing](/user-guide/billing) page for a feature comparison.
  </Accordion>

  <Accordion title="What happens if my payment fails?">
    Your subscription enters a "past due" state with a 7-day grace period. All features remain active during this period so you can update your payment method. If unresolved after 7 days, your organization is automatically downgraded to the Free plan. See [Billing](/user-guide/billing#failed-payments--grace-period) for details.
  </Accordion>

  <Accordion title="Can I use my own AI API keys (BYOK)?">
    Yes. Under **Settings > My AI Keys**, you can add your own OpenAI, Anthropic, or Google Gemini API keys. When a BYOK key is configured, your requests use your personal account and do not count against your plan's AI token limit. Keys are encrypted with AES-256-GCM. See [Settings](/user-guide/settings) for setup instructions.
  </Accordion>

  <Accordion title="How do I cancel my subscription?">
    Go to **Billing** in your admin dashboard and click **Manage Billing**. This opens the Dodo Payments portal where you can cancel your subscription. Your plan remains active until the end of the current billing period. You will not be charged again after cancellation.
  </Accordion>
</AccordionGroup>

## Projects & PRDs

<AccordionGroup>
  <Accordion title="How do I create a new project?">
    Click **New Project** from your dashboard or the Projects page. Choose a template (or start blank), give it a name, and begin your AI conversation. The AI guides you through requirements gathering, and you can generate a PRD at any point. See the [Quickstart](/quickstart) for a step-by-step walkthrough.
  </Accordion>

  <Accordion title="Can I use templates?">
    Absolutely. thig.ai provides curated templates for SaaS, Mobile, eCommerce, FinTech, Healthcare, and more through the template marketplace. You can also create custom templates for your organization with tailored sections, sample questions, and AI system prompts. Learn more in [Templates](/user-guide/templates).
  </Accordion>

  <Accordion title="How do I edit a generated PRD?">
    Once a PRD is generated, it opens in a rich text editor with full markdown support, tables, images, and formatting. You can edit any section directly, use AI writing assistance to refine paragraphs, and track changes through version history. See [PRD Editor](/user-guide/prd-editor) for details.
  </Accordion>

  <Accordion title="What PRD styles are available?">
    When generating a PRD, you can choose from five styles: **Comprehensive** (detailed, all sections), **Technical** (engineering-focused with specs and architecture), **Business** (stakeholder-oriented with market analysis), **Lean** (minimal viable scope), and **Agile** (user stories and sprint-ready). Each style adjusts the structure and depth of the output.
  </Accordion>
</AccordionGroup>

## Collaboration

<AccordionGroup>
  <Accordion title="How do I share a PRD with external stakeholders?">
    Open your project and click **Share**. You can generate a shareable link that external recipients can view without logging in. Options include password protection, expiration dates, view count limits, and download permissions. See [Collaboration](/user-guide/collaboration) for all sharing options.
  </Accordion>

  <Accordion title="Can multiple people edit a PRD at the same time?">
    thig.ai supports real-time presence — you can see who is currently viewing a document and where they are in it. Threaded comments allow asynchronous discussion on specific sections. If someone else saves changes, you receive a notification with an option to reload.
  </Accordion>

  <Accordion title="How do team invitations work?">
    Organization admins can invite new members from the **Team** page. Enter the invitee's email and assign a role (Admin, Member, or Viewer). They receive an email with a link to join your organization. If they do not have an account, they can create one during the acceptance flow. See [Team Management](/user-guide/team-management) for details.
  </Accordion>
</AccordionGroup>

## Exports

<AccordionGroup>
  <Accordion title="What export formats are supported?">
    thig.ai supports five export formats: **PDF** (styled with tables and your org logo), **HTML** (self-contained, opens in any browser), **DOCX** (Microsoft Word compatible), **Notion** (creates a Notion page via OAuth), and **Google Docs** (creates a Google Doc in your Drive). See [Exports](/user-guide/exports) for format details and setup.
  </Accordion>

  <Accordion title="Can I schedule automatic exports?">
    Yes, on Pro plans and above. Go to **Settings > Scheduled Exports** to configure recurring exports. You can schedule weekly digests, trigger on status changes, set custom cron expressions, or schedule one-time exports. Delivery methods include email and webhooks. See [Exports](/user-guide/exports#scheduled-exports) for configuration options.
  </Accordion>
</AccordionGroup>

## API & Integrations

<AccordionGroup>
  <Accordion title="Does thig.ai have an API?">
    Yes. thig.ai provides 225+ RESTful API endpoints for managing projects, chat conversations, templates, exports, notifications, audit logs, team workspaces, and organization settings. Authenticate with session cookies or REST API keys (`thig_...`) created from **Settings > Developer**. API keys are available on Starter plans and above. See the [API Reference](/api-reference/introduction) for full endpoint documentation.
  </Accordion>

  <Accordion title="How do I connect to Notion or Google Docs?">
    Go to **Settings > Integrations** and click **Connect** next to Notion or Google Docs. You will be redirected to authorize thig.ai with your account. Once connected, you can export PRDs directly to those platforms. Google Docs uses your existing Google sign-in credentials if you registered with Google OAuth.
  </Accordion>

  <Accordion title="What are webhooks used for?">
    Webhooks let you receive real-time notifications when events happen in your organization — such as a project status change, PRD generation, or export completion. thig.ai supports 40+ event types across project, PRD, comment, team, AI, and billing categories. Configure webhook endpoints in **Settings > Webhooks** and select which events to subscribe to. See [Webhooks](/user-guide/webhooks) for all event types.
  </Accordion>

  <Accordion title="Can stakeholders approve PRDs without an account?">
    Yes. Share a PRD via link, and stakeholders can review, approve, or reject it with feedback — no login required. See [Stakeholder Reviews](/user-guide/stakeholder-reviews).
  </Accordion>

  <Accordion title="What are approval workflows?">
    Enterprise organizations can configure multi-approver workflows for critical actions like publishing PRDs, exporting documents, or deleting projects. Workflows require a configurable number of approvals before the action proceeds. See [Approval Workflows](/user-guide/approval-workflows).
  </Accordion>

  <Accordion title="How does the AI model tier system work?">
    thig.ai uses three AI model tiers — Fast, Balanced, and Powerful — that automatically match the right model to each task. Quick tasks like suggestions use fast models; PRD generation uses powerful models. Organization admins can customize which models and tiers are available. See [AI Model Configuration](/user-guide/ai-model-config).
