# Which AI email assistant writes replies that sound like me? > Fyxer and Superhuman learn your style from sent emails and draft replies for you to review; Lindy drafts by your own rules. Free lesson. Source: https://learn.ynteractive.com/content/questions/ai-email-assistant-writes-in-my-voice · Updated 2026-10-21 · Free from Stepthrough (https://learn.ynteractive.com) By [Robert Breen](https://learn.ynteractive.com/content/about) · Published October 21, 2026 · Updated October 21, 2026 · 4 min read [Fyxer](https://learn.ynteractive.com/content/glossary/fyxer-ai) is the most direct fit: it works inside Gmail and Outlook, learns how you write from your sent emails, and leaves draft replies for you to review, never sending on its own. Superhuman does the same if you are happy to switch to its email app, and Lindy fits when you want strict rules about which emails get a draft and what each draft may say, as in [Answer Client Emails in Half the Time using Lindy](https://learn.ynteractive.com/content/lindy-ai-draft-client-email-replies). "Sounds like me" comes from two things: examples of how you write, and the facts you would use. Tools that read your sent folder get the first part. The second part, your prices, policies and dates, you still have to give them, or check yourself. ## What are my options, and what decides between them? - **Fyxer.** Sorts your inbox and drafts replies inside Gmail or Outlook. Fyxer says it reads your recent sent emails to learn greetings, sentence length and tone, and adjusts by recipient. Deciding factor: you want to keep your current email app and have drafts waiting. - **Superhuman.** A fast email app for Gmail and Outlook accounts. Its Auto Drafts learn formality, word choice, greeting, sign-off and length from your past emails, and you can add personal details in its settings. Deciding factor: you live in email and want a new app built around speed. - **Lindy.** An [AI assistant](https://learn.ynteractive.com/content/glossary/ai-assistant) you give routines: when a certain email arrives, draft a reply. You write the instructions, narrow which emails count and set it to ask for approval before anything is sent. Deciding factor: client email where you want control over every rule. - **Gmail with Gemini.** Drafts replies and summarizes threads inside the Gmail you already use, with your Workspace or Google AI plan. Deciding factor: you want help in Gmail with nothing new to install, and you will edit the tone yourself. - **n8n.** Build your own: an agent reads each new email and saves a reply as a [Gmail draft](https://learn.ynteractive.com/content/glossary/gmail-draft), using a system message you write. Deciding factor: you want full control and your business facts built in. See [the best AI email assistants](https://learn.ynteractive.com/content/compare/best-ai-email-assistants) for more, and [Gmail filters vs n8n vs ChatGPT](https://learn.ynteractive.com/content/compare/ai-email-drafts-gmail-filters-vs-n8n-vs-chatgpt) for the do-it-yourself routes. ## How do I get drafts that really sound like me? 1. **Start with drafts only.** Never let a new assistant send. 2. **Give it real examples.** A few of your best replies teach more than a description of your style. 3. **Write down your facts**: hours, prices, policies and sign-off. An assistant that knows how you write but not what you charge will still guess. 4. **Tell it what to do when it does not know**, such as writing [CHECK] instead of inventing. 5. **Edit for two weeks.** Your corrections are how most of these tools improve. ## What does this look like in a real lesson? In [the Lindy lesson](https://learn.ynteractive.com/content/lindy-ai-draft-client-email-replies) the office at a four-person accounting firm gets about 40 client questions a week. You open Lindy's Gmail integration and set Guardrails to Ask for approval, so nothing that changes data happens without your OK. You create a routine that runs when an email arrives, with a test rule so only subjects starting with "Test - client question" trigger it. The instructions say drafts only, never send, and write [CHECK] when a fact is missing. You send yourself a test, authorize Gmail drafts once, and read the draft in the same thread before widening the routine with a plain-language filter. To give any assistant your voice and facts in one place, [ChatGPT Projects: Your Brand Voice in One Place](https://learn.ynteractive.com/content/chatgpt-projects-brand-voice) has you add brand voice instructions, a price list and a style guide to a project, then answer a price question in a fresh chat without explaining the business again. ## What mistakes should I avoid? - **Turning on auto-send.** A reply that sounds like you but promises the wrong date is worse than no reply. - **Judging it on day one.** Style tools need your edits to settle in. - **Feeding it client data you are not allowed to share.** Check your company's AI policy before connecting a work inbox. - **Skipping facts.** Voice is not knowledge. Give it the details, or check every number. ## Key takeaways - Fyxer: drafts in your style inside Gmail or Outlook. - Superhuman: a new email app with drafts that learn from past mail. - Lindy: drafts by your own rules, with approval required. - Keep every assistant on drafts only, and check the facts. ## Frequently asked questions **Can ChatGPT write emails that sound like me?** Yes, if you give it samples and your facts, ideally in a project. It will not see your inbox unless you connect it, so you paste the thread each time. **Will the assistant send emails without asking?** Fyxer says it never sends without your permission, and Lindy can be set to ask for approval. Keep any tool on drafts until you trust it. **Does it work with Outlook?** Fyxer and Superhuman both support Outlook accounts.
