No-code AI apps

Dify (Dify Open Source License, Apache plus conditions): build chatbots and AI workflows visually.
Langflow (MIT): a drag-and-drop builder for agents and RAG, with built-in API and MCP servers.
n8n (fair-code, not OSI-approved): automate work across apps, APIs and AI, with a visual canvas and custom code when you need it.

Image generation

ComfyUI (GPL-3.0): a node-based visual editor for diffusion models, very flexible.
Fooocus (GPL-3.0): a one-click, Midjourney-style generator that works offline.
InvokeAI (Apache-2.0): a polished creative studio for AI images.

Video generation

Wan2.2 (Apache-2.0): text or image to video with open models.
HunyuanVideo (check the licence): Tencent's open text-to-video model.
LTX-2 (check the licence): fast video with synchronised audio.

Speech

Whisper (MIT): transcribes and translates speech, including Urdu.
faster-whisper (MIT): the same model running up to four times faster with less memory.
Piper (GPL-3.0): lightweight offline text-to-speech voices.

The warning I put on the slide

Model weights can carry separate terms from the code. A project's code can be MIT-licensed while the model it downloads has a different licence that limits commercial use. Always read the model card before using a model in a product or a paid project.

A first project for each

Whisper: transcribe a lecture recording in Urdu and clean the transcript.
n8n or Dify: make a bot that answers questions from your department's handbook.
ComfyUI or Fooocus: generate illustrations for a school project, and credit the tool in your report.

These tools need a decent computer for images and video. If yours is slow, start with speech and no-code tools and leave video for later.
