Aeralis solves a specific problem: you're writing the same emails over and over, but each one needs different context. Templates don't cut it because you end up rewriting half of them anyway.

With Aeralis, you feed the AI your context - product docs, pricing pages, FAQs, knowledge base URLs. When you generate a draft, it pulls from that context to write emails with the right details, not generic filler.

It lives inside Gmail as a Google Workspace add-on. No tab switching, no copy-pasting. Click a button, get a draft, edit if needed, send.

Key features: โ€ข Context-aware generation using your URLs and documentation โ€ข Multiple profiles for different use cases (support, sales, personal) โ€ข One-click drafts for new emails and replies โ€ข Reply All support โ€ข Google Search grounding for real-time information โ€ข Google Maps grounding for location-aware responses โ€ข Tone customization (professional, casual, formal, friendly)

Built for support teams, sales teams, founders, and anyone who spends too much time on repetitive emails.

Pricing: Free tier available, Pro and Business plans for advanced features.

Possible disadvantages of SimpleX

  • Limited advanced features
    SimpleX focuses on simplicity, which means it may lack more sophisticated decision analysis features such as sensitivity analysis, probability weighting, or Monte Carlo simulations that more advanced tools offer.
  • Low visibility and community
    SimpleX is a relatively niche tool with a small user base, which means limited community support, fewer tutorials, and less peer feedback compared to more established decision-making platforms.
  • Potential oversimplification
    For complex decisions involving many interdependent variables, the simplified framework may not adequately capture nuances, dependencies, or non-linear relationships between criteria.
  • Limited collaboration features
    The tool may lack robust collaboration capabilities for team-based decision-making, such as real-time co-editing, role-based access, or voting mechanisms for group consensus.
  • No offline functionality
    Being a web-based tool, SimpleX requires an internet connection to function, which can be a limitation in situations where connectivity is unreliable or unavailable.

Questions & Answers

As answered by people managing Aeralis.ai and SimpleX.

What makes your product unique?

Aeralis.ai's answer

Most AI email tools write generic text that you end up rewriting anyway. Aeralis is different because it actually knows your stuff - your pricing, your product details, your FAQs. You feed it context URLs and it uses that information to write emails with accurate, specific details. It's not just AI writing, it's AI writing with your knowledge base built in.

Why should a person choose your product over its competitors?

Aeralis.ai's answer

Three reasons: context, location, and simplicity. Unlike standalone AI writers, Aeralis lives inside Gmail - no copy-pasting between tabs. Unlike generic tools, it pulls from your actual documentation so emails include real details, not filler. And unlike complex enterprise solutions, it takes 2 minutes to set up. You add your URLs, pick a tone, and start generating.

How would you describe the primary audience of your product?

Aeralis.ai's answer

People who answer a lot of similar emails but need each response to be different. Support teams handling customer questions. Sales people doing personalized outreach. Founders and freelancers managing client communication. Anyone who's tried email templates and found themselves rewriting them every time.

What's the story behind your product?

Aeralis.ai's answer

I built Aeralis to solve my own problem. I run another product called Sync2Sheets, and I was spending my mornings answering support emails. Templates weren't enough - every email needed the same information (pricing, features, troubleshooting) but in different contexts. So I built something that could write emails with my product knowledge baked in. Started as a personal tool, now it's available for anyone with the same problem.

Which are the primary technologies used for building your product?

Aeralis.ai's answer

Google Gemini for AI generation, Next.js for the web application and API, Firebase for authentication and database, and the Google Workspace Add-ons framework for Gmail integration. Built primarily using Claude Code for AI-assisted development.

Who are some of the biggest customers of your product?

Aeralis.ai's answer

  • Early-stage product, growing organically
  • Currently used by indie founders, freelancers, and small support teams
  • No enterprise customers to list yet
