Kel vs Otto Engineer: Which is better?

Kel is an AI-based assistant embedded in your Command Line Interface (CLI). It is designed to augment productivity by automating repetitive tasks and enhancing the overall efficiency of your CLI. Kel is equipped with multiple Languages for Learning Machines (LLMs) support including OpenAI, Anthropic, and Ollama, whilst also supporting OpenAI Assistants. It further allows users to engage in unique interactions such as 'chatting' with their artifacts by uploading their files to the assistant. Developers can personalize their assistant using their own API keys for OpenAI or Anthropic, a feature that might soon extend to other LLMs.

Otto Engineer, also known as Otto, is an AI-based software that acts as an autonomous coding assistant. Catered for developers, it runs directly in the browser and is designed to simplify the process of software engineering. One of its key features includes the ability to execute code and conduct testing, iterating through the code until a functioning version is achieved. It can handle errors through continuous iterations, striving for functional code. Another feature, aided by Web Containers technology, allows it to execute code safely in isolation, with the use of a virtual, in-memory file system. This means that Otto can operate securely without risking system vulnerabilities. The software also requires no setup, indicating an ease-of-use for users who just need to instigate a new chat and let Otto work. It can run commands and modify code in the embedded terminal and editor, which users can observe. Additionally, Otto is designed to operate in a genuine environment, able to install and use npm packages, amend its TS config, and write its own tests. Users can use it to create complicated utility types, eliminating the issue of 'hallucinated' code that doesn't function properly.
