ThunderAI

ThunderAI is a Thunderbird Addon that uses the capabilities of ChatGPT, Google Gemini, Claude or Ollama to enhance email management.

It enables users to analyse, write, correct, assign tags, create calendar events or tasks and optimize their emails, facilitating more effective and professional communication.

ThunderAI is a tool for anyone looking to improve their email quality, both in content and grammar, making the writing process quicker and more intuitive.

You can also define, export and import your own custom prompts!

In any custom prompt you can use additional data placeholders!
