This guide helps you install T3AC Premium (EXT:ns_t3ac) on a TYPO3 project for the first time. T3AC needs AI Foundation (EXT:ns_t3af). AI Foundation connects your AI providers (API keys, models, prompts, and shared AI services). Without it, T3AC cannot run. These extensions do not change how your website looks on the frontend by themselves. They work in the backend and power the AI chatbot. Keep both T3AC and AI Foundation enabled.

​
Quick overview for new customers

You will install and activate these pieces:
  1. License Manager (EXT:ns_license) — unlocks your Premium download
  2. T3AC (EXT:ns_t3ac) — the AI Chatbot extension (and related packages such as T3CS where required)
  3. AI Foundation (EXT:ns_t3af) — shared AI engine used by T3AC (free on TER)
  4. Database updates — so TYPO3 creates the required tables
  5. TypoScript includes — load the required static TypoScript
  6. AI provider setup — so T3AC can send AI requests
  7. Final check — confirm modules load and the license is active
Follow the steps below in order. Choose either Non-Composer or Composer in Step 2 — not both. After installation, you will use the T3AC backend module to:
  • Manage data sources such as sitemaps, PDFs, TYPO3 pages, web pages, and Q&A records.
  • Run a training pipeline that keeps chatbot answers in sync with your project content.
  • Configure and monitor the AI chatbot.
  • View usage analytics for chatbot activity.
If you are upgrading from an older version (2.2.1 or earlier) to the latest release, follow Reinstall After Upgrading instead of this installation guide.

​
Before you start

Make sure you have:
  • Backend access as an administrator
  • Your T3AC license key from T3Planet
  • Decided whether your project uses Composer or the TYPO3 Extension Manager
  • An AI provider account/API key ready (for example OpenAI) for Step 6

​
Step 1 — Install the License Manager

Install the latest version of EXT:ns_license before continuing. The License Manager controls access to T3Planet Premium packages and is required to download and activate T3AC.

​
Step 2 — Activate the License

Pick the path that matches your project.

​
Non-Composer Installation

Use this workflow when your project installs T3Planet extensions from the TYPO3 backend:
  1. Open Admin tools → T3planet License Manager.
  2. Enter your T3AC license key.
  3. Activate the license.
  4. Confirm that the latest T3AC package is downloaded.
  5. Confirm that AI Foundation (EXT:ns_t3af) is installed automatically or available after activation.

​
Composer Installation

Use this workflow when your TYPO3 project is managed with Composer:
  1. Check the T3Planet Composer repository configuration.
  2. Update the only parameter so the project can download T3AC and T3CS:
  1. Install the T3AC package:
  1. Verify that the installation completed successfully.
  2. Confirm that AI Foundation (nitsan/ns-t3af / EXT:ns_t3af) is installed. If it is missing, install it using Step 3 — Install AI Foundation.

​
Step 3 — Install AI Foundation

AI Foundation (EXT:ns_t3af) is required before T3AC can be used. It provides the shared AI provider configuration, models, API access, logs, and service layer used by T3AC. If AI Foundation was already installed in Step 2, you can skip to Step 4. AI Foundation is the shared AI infrastructure for T3Planet AI Universe extensions. Complete the parent setup first, then continue with the remaining T3AC steps below. AI Foundation is available from the TYPO3 Extension Repository (TER). Download / TER page: https://extensions.typo3.org/extension/ns_t3af

​
AI Foundation has two provider modes

In AI Foundation → AI Providers, choose how T3AC gets AI access: Your Own API Keys Use this mode when you want to connect your own AI vendor accounts. You store and manage your API keys (for example OpenAI, Anthropic, Gemini) in AI Foundation and run AI features through those providers. T3Planet Credits T3Planet Credits is T3Planet’s managed AI access for AI Foundation. It lets your TYPO3 site use AI features without storing or managing your own vendor API keys.

​
Option 1 — Extension Manager (TER)

  1. Open Admin Tools → Extensions.
  2. Select Get Extensions.
  3. Search for ns_t3af or AI Foundation.
  4. Install and activate the extension.
  5. Flush all TYPO3 caches.

​
Option 2 — Composer

If AI Foundation is not already present after installing T3AC, install it with:
Then flush all TYPO3 caches. Helpful AI Foundation references:

​
Premium Version

T3AC is a Premium extension and requires a valid T3Planet license for download and activation. For license activation and access to premium features, see: https://docs.t3planet.de/en/latest/License/Index.html
AI Foundation (EXT:ns_t3af) is free and available from the TYPO3 Extension Repository (TER). Premium licensing applies to T3AC — not to AI Foundation.

​
Step 4 — Run Database Analyzer

After installing the extension, apply all pending database changes:
  1. Open Admin Tools.
  2. Go to Maintenance.
  3. Open Analyze Database Structure.
  4. Apply all pending database schema updates.
Run this before using T3AC modules in the TYPO3 backend.

​
Step 5 — Configure/Load required TypoScripts

T3AC and T3CS ship static TypoScript that must be included on your site.
  1. Switch to the root page of your site.
  2. Open the TypoScript module and select Edit TypoScript Record / Info/Modify.
  3. Click Edit the whole template record and open the Includes tab.
  4. Under Include static (from extensions) / site sets, add:
  • AI Chatbot/Search - TYPO3 Extension [nitsan/ns-t3cs]
  • AI Chatbot - TYPO3 Extension [nitsan/ns-t3ac]
  1. Save the template and flush TYPO3 caches.

​
Step 6 — Configure the AI Provider

After installation:
  1. Open AI Foundation in the TYPO3 backend.
  2. Configure your preferred AI provider.
  3. Save the provider and model configuration.
  4. Verify the AI connection with a test request.
T3AC will not function correctly until AI Foundation has a working AI provider configuration.

​
Step 7 — Verify the Installation

Before handing the system to editors, verify that:
  • EXT:ns_t3ac is installed and active.
  • EXT:ns_t3af is installed and active.
  • The T3AC license is active.
  • Database Analyzer changes are applied.
  • The AI provider is configured in AI Foundation.
  • TYPO3 caches are cleared.
  • T3AC backend modules load without errors.
If all items above are true, installation is complete. Next, add data sources and run training in the T3AC module.
