Question: I need a chat companion that can help me generate ideas and compose emails, while ensuring the security and privacy of my data.

First, ChatGPT Writer is a powerful AI tool that can help you with your writing tasks, including emails, with features like grammar checking, rewriting, tone shifting and summarization. It works in multiple languages and has a sophisticated integration with Gmail. It's got strong security and confidentiality protections, too, so it's a good option if you're concerned about keeping your data private.

Another option is Langdock, which serves as a daily chatbot for idea generation and writing but also comes with customizable assistants and workflows to automate repetitive tasks. Langdock is GDPR compliant and uses AES-256 data encryption, so your data is protected. It also integrates with other tools and can be customized to your needs.

For a dedicated email writing assistant, WriteMail.ai uses AI to suggest clarity, concision and tone in real time. It works in multiple languages and has AI editing for grammar and spelling. With its simple interface and fast response time, WriteMail.ai can help you save time and write better emails.

Last, Addy automates and optimizes email workflows, for example with prioritized emails and follow-up reminders. It works with Gmail, Outlook and Yahoo, and it's got data privacy protections with strict security controls, so you can draft, reply and follow up without worrying about losing control over your data.
