ReplaiGPT makes you build reusable context profiles — details about yourself, your products, your standard answers — and then uses that stored context plus the currently open email to produce a reply that fits the actual request. The extension works directly inside Gmail. You click the ReplaiGPT icon on an open message, pick one of your saved contexts, choose a language, and hit Generate. The result appears in roughly 10–15 seconds and can be sent after a quick edit. It is aimed at people who answer the same kinds of recurring requests over and over and want a faster first draft. Privacy is handled locally: contexts and emails are stored in your browser rather than on ReplaiGPT's servers, and you supply your own OpenAI API key, so usage is billed by OpenAI directly. The basic version is free, with in-app purchases available. **Pricing & Plans:** Freemium. The basic version is free to use and requires your own OpenAI API key (billed by OpenAI). Optional in-app purchases unlock extra functionality. - **Custom context profiles:** Create and save reusable descriptions of yourself, your products or your business so every AI reply carries the right background. - **One-click Gmail replies:** Open a message, click the extension icon, select a context and generate a draft reply without leaving your inbox. - **Bring your own OpenAI key:** Connect your own OpenAI API key so generation costs go to your own account and you keep control of the model. - **Local-first privacy:** Emails and contexts stay in your browser instead of being stored on the developer's servers. - **Multilingual output:** Choose the language from the context dropdown and generate replies in any popular language. **Strengths:** Replies reflect your own context instead of generic AI phrasing; No server-side storage of emails — contexts stay in your browser; Works in any language and with your own OpenAI API key; Free basic tier with no upfront cost **Limitations:** Requires a separate OpenAI API key and account; Generation takes around 10–15 seconds per reply; Limited user base, so fewer community tips or reviews [Profile (Markdown)](https://openaitools.app/tool/replaigpt.md) ## SIFA Reply SIFA Reply is a small, single-purpose browser extension for people who live in Gmail and want to cut down the time they spend typing routine messages. Rather than being a full email client or an inbox manager, it focuses narrowly on the writing itself: reading the message in front of you, understanding its intent, and handing back a draft you can send with minimal editing. The extension presents itself as a personal AI email assistant. When a thread is open you can ask it for a reply, and it will generate an answer written for that specific context, along with a suggested subject line and greeting. A separate mode lets you start from scratch, generating a fresh message from your own short description of what you need to communicate. Because it runs as a Chrome extension, everything happens in the same tab where you already read your mail, so there is no app switching. SIFA Reply is published by the team behind trysifa.com and is distributed through the Chrome Web Store. The listing is modest in scale, with a small number of users and its most recent version dated to early 2023, so it is best suited to individuals who want a simple drafting shortcut rather than an enterprise-grade assistant with a large support organisation behind it. **Pricing & Plans:** Free to install, with in-app purchases listed in the Chrome Web Store. The developer has not published a public price sheet, so check trysifa.com for current tiers and allowances. - **AI-drafted replies in one click:** Highlight an incoming email and SIFA Reply produces a thoughtful, personalised answer you can edit or send as written. - **New email composition from a prompt:** Describe what you want to say and the extension writes a complete message rather than forcing you to start from a blank page. - **Smart subject and greeting suggestions:** The tool inspects the context of a thread and proposes a fitting subject line and salutation to match. - **Works inside your Gmail tab:** A small pop-up UI on top of Gmail keeps the AI assistant one click away while you read and triage. - **Tone that stays professional:** Replies are written to sound like a normal business email rather than a robotic template, which helps avoid an obviously machine-generated tone. **Strengths:** Installs in seconds and adds a drafting button directly to Gmail; Handles both replies and brand-new messages from one small interface; Suggests subject lines and greetings as well as body copy; Discloses how it handles personal communications data **Limitations:** Very low install base and only a 2023 update, so active development is unclear; Requires a paid unlock (in-app purchase) to access its full feature set; Limited to Gmail; no Outlook or other mail client support mentioned [Profile (Markdown)](https://openaitools.app/tool/sifa-reply.md) ## Frequently Asked Questions ### How do ReplaiGPT and SIFA Reply compare in monthly traffic?
