## DevBot

DevBot is a browser extension aimed at developers who want AI help without switching tabs or opening a separate chat app. It hooks into the page you already have open, so a code block in documentation, a snippet in a tutorial, or a chunk of your own project code can be transformed in place using a single shortcut.

The workflow is deliberately minimal. You select the code you care about, press Ctrl/Cmd+Shift+B, and type a short instruction such as "convert this to TypeScript" or "optimize this loop." DevBot sends the selection plus your prompt to an AI model and returns a revised version that you can paste back into your editor. Because it works on any page, it is most useful for quick rewrites, language conversions, and explanation-driven refactors during reading or debugging.

The extension is distributed through the Chrome Web Store by an independent developer, is small in size, and declares that it does not collect or sell user data. It is best treated as a convenience tool rather than a full IDE replacement.

**Pricing & Plans:** Free Chrome extension. No subscription or pricing page is offered; install it from the Chrome Web Store at no cost.

- **Ctrl/Cmd+Shift+B activation:** Trigger AI assistance instantly on any page with a single keyboard shortcut, no side panel or separate tab required.
- **Selection-based code rewriting:** Highlight a snippet and DevBot generates, refactors, or transforms it according to your written instruction.
- **Works across the web:** Runs on any site you browse, so documentation snippets, forum answers and tutorial code can all be reworked in place.
- **Lightweight install:** A small extension footprint that stays out of the way until you invoke it.
- **Privacy-conscious design:** The developer declares that user data is not sold to third parties.

**Strengths:** Free to install and use from the Chrome Web Store; Single-shortcut workflow keeps you in the page you are reading; Works on any website, not just a specific editor; Small download size

**Limitations:** Only 11 users and one rating, so community feedback is thin; Requires selecting text manually, with no editor integration; Last update was December 2024, so the model behind it may lag newer options

## Smart Assistant by Mailbutler

Mailbutler is an email productivity extension for Apple Mail, Gmail, and Outlook, and its AI component is the Smart Assistant. Rather than being a standalone chatbot, the assistant is embedded in the compose and read views of the inbox you already use. It can compose an email from a few short keywords, draft a reply framed as positive, negative, or neutral, summarize an entire thread, or correct grammar and phrasing in a draft — all without switching apps or copying text elsewhere.

The AI layer is deliberately connected to the rest of Mailbutler's toolkit. Follow-up suggestions analyze tracked emails — opens, link clicks, and engagement patterns — then classify threads as high, medium, or low priority, and the Smart Assistant can draft the follow-up itself. That combination of tracking data plus generation is what makes the assistant useful in sales and client-facing work, where knowing who to chase matters as much as what to write.

The rest of the extension supplies email tracking, message templates, mail merge, smart timing, tasks and notes, shared inbox assignments, and signature marketing. On privacy, Mailbutler is ISO/IEC 27001 certified and GDPR compliant with servers in Frankfurt, Germany. Emails are still sent from your own server, message content is not analyzed or stored in the backend for general operation, and when you use the Smart Assistant the email body is sent to OpenAI only for that request, with email addresses replaced by dummy variables. Plans range from a free-forever Starter tier to paid Smart and Business plans, all starting with a free 14-day trial that includes every feature and no credit card requirement.

**Pricing & Plans:** There is a free-forever Starter plan plus a free 14-day trial with all features and no credit card. Paid tiers are billed per user per month (about $4 Starter, $7 Professional, $11 Smart, and higher Business pricing when billed yearly, with monthly pricing slightly higher) and available in USD or EUR. The AI Smart Assistant is included from the Smart plan upward; email tracking, templates, mail merge, tasks, and signatures are spread across the tiers.

- **AI drafting and reply generation:** Turn a handful of keywords or bullet points into a full, sendable email, and generate replies framed as positive, negative, or neutral depending on the situation.
- **Thread summarization:** Condense long email chains into the key points so you can catch up fast and respond without re-reading every message.
- **Grammar and tone correction:** The assistant rewrites and corrects your message for grammar, spelling, and phrasing before you hit send.
- **Smart Follow-ups:** Follow-up suggestions combined with open and click tracking tell you which threads are urgent, and the assistant can draft the follow-up for you.
- **Built into a full email toolkit:** The AI features sit alongside tracking, message templates, mail merge, tasks and notes, shared inbox assignments, and email signatures so your whole workflow stays in one inbox.

**Strengths:** Works inside Apple Mail, Gmail, and Outlook instead of forcing another app into your stack; AI drafting, summarization, and grammar checks are combined with tracking and follow-up prioritization in one place; Strong privacy posture: ISO/IEC 27001 certified, GDPR compliant, and servers located in Germany; Free 14-day trial unlocks all features with no credit card required

**Limitations:** Most genuinely useful AI features require a paid plan, and full automation sits on higher tiers; Free tier is limited, so the free-forever Starter plan is best treated as a lite entry point; Used for email drafting, email body text is transmitted to OpenAI (addresses are tokenized), which some compliance teams will want to review; Feature depth varies slightly by client since it is an extension layered over three different email apps
