🚀 Introducing TrixGenius Alpha 0.1.2 – Now with AI-Powered Math Evaluation!

April 15, 2025

📢 I just released a new version of my Rails engine and gem: TrixGenius! This gem extends the beloved Trix Editor with some fresh, AI-powered superpowers — all using Hotwire (Turbo + Stimulus).

Whether you’re building internal tools, CMS interfaces, or AI-enhanced content platforms, TrixGenius gives your rich text editor a serious productivity boost.

✨ What’s New in Alpha 0.1.2?

This update introduces a brand-new feature that I’m super excited about:

➕ Calculate Math Expressions with a Single Click!

Users can now type math expressions inside the Trix editor (like (5 + 3 * 2)), hit the new “Calculate” button, and automatically get the result injected back into the content.

🧠 Under the hood:

• Detects top-level math expressions in parentheses.
• Uses a secure Ruby evaluator to compute results (e.g., (3+4*2) becomes 3+4*2=11).
• Optionally calls an AI (e.g., DeepSeek) to reformat the text while preserving the original context.

🎥 Here’s what it looks like:

Input: Let’s compute (8/2+3*2).

Result after clicking “Calculate”: Let’s compute 8/2+3*2=10.

🔧 How it Works – Under the Hood

The magic happens through:

✅ A Stimulus Controller

• Adds a “Calculate” button to the Trix toolbar.
• Collects the editor content.
• Sends it via AJAX to your Rails backend for evaluation.

✅ A Rails Endpoint (/trix_genius/calculate_expression)

• Securely parses and evaluates expressions.
• Integrates optional AI enhancement.
• Returns transformed HTML content.

✅ Generator Updates

The gem now automatically injects this route:

# TrixGenius: Auto-added route
post "/trix_genius/correct_spelling", to: "trix_genius#correct_spelling"

It’s all scaffolded into your app with a single command:

bin/rails g trix_genius:install

---

🧪 Still in Alpha — But Growing Fast

This gem started with a simple idea: make Trix smarter. The first feature was a “Correct Spelling” button. Now, we’ve added math evaluation, and we’re already working on:

• Integrating ChatGPT & Qwen.ai
• Feature toggles (enable/disable toolbar buttons)
• Specs for all features

---

🔗 Try It Out

You can install the gem from RubyGems:

gem 'trix-genius', '~> 0.1.2'

Then run the install generator:

bundle install
bin/rails g trix_genius:install

Demo it with Action Text + a simple scaffold:

bin/rails g scaffold Post title:string content:rich_text
