• Knowledge, productive note-taking apps: Obsidian and Notion.
• Search Engines/AI: ChatGPT, Gemini, Bing -Copilot-, Claude, perplexity, Deep Seek, Poe, SearXNG (it is an open-source metasearch engine), DuckDuckGo, Gemini, Aria.

  In DuckDuckGo, the exclamation mark ("!") is referred to as a “bang.” It allows you to perform searches on specific websites directly from the DuckDuckGo search bar, e.g., !g (Google), !w (Wikipedia), !yt (YouTube).

• Ollama allows you to run Llama2, Code Llama and other models.

  user@pc:~$ ollama run llama2
  user@pc:~$ A circle has the radius 5. What is the area of the circle?
  The area of a circle can be calculated using the formula: Area =πr², where r is the radius of the circle. In this case, the radius of the circle is 5, so the area of the circle is: Area = π(5)² = 3.14(5²) = 78.5
  
  So the area of the circle is 78.5 square units.
