Title
Beyond CRUD: Building Conversational AI Agents in Rails
Abstract
This talk explores the trend of multimodal interactions with Large Language Models (LLMs), focusing on voice interfaces.
You will see how you can leverage tools like RubyLLM, Stimulus, and Action Cable to build AI voice agents that provide natural and engaging user experiences.
It covers the building blocks of AI Agents, in-browser vs server-side architectures, transport layers for audio streaming, token optimization strategies, Retrieval-Augmented Generation (RAG), and tools integration.
Detailed Description
Pitch
It’s 2026, AI agents are everywhere. Understanding how to leverage LLMs for building this kind of application is a must-have skill for developers.
As many providers are developing multimodal models, we can see a trend towards more natural and intuitive ways for users to interact with applications. Voice interfaces are becoming increasingly prevalent, offering hands-free access to information and services.
While working on a software boutique that delivers high-quality software solutions using Rails and AI, I’ve been involved in a couple of projects that required building AI voice agents.
In this talk, I’ll share insights and practical knowledge on how Rails developers can build AI voice agents using the Rails ecosystem.
Outcomes
After attending this talk, the audience should know:
- The building blocks of AI agents and how to architect voice agents
- Ruby and Rails tools available for building AI agents
- The trade-offs between in-browser and server-side architectures for voice agents
Outline
Introduction
- Discuss how AI applications are not a Python-only domain anymore show the difference between AI/Context and ML Engineering

Why This Talk Matters
Large Language Models (LLMs) have been around for a while. They are a thing. They are too big to ignore. Developers need to understand how to leverage LLMs to build AI-powered applications.
Within this context, multimodal interactions are trending. It’s not a coincidence that more and more providers are working on multimodal models. Voice interfaces are becoming more prevalent as they offer a natural and intuitive way for users to interact with applications.
Combining voice interfaces with LLMs can create powerful and engaging user experiences.
Assistant
I have analyzed your CFP draft. It is strong technically and addresses a very relevant topic for Rails developers who feel “left out” of the AI boom (usually dominated by Python).
Here is the breakdown using the 4 U’s Framework and Feature vs. Benefit analysis, followed by title suggestions and specific questions to finalize the submission.
1. The 4 U’s Analysis
- Useful (4/4): Very high. Rails developers are actively seeking ways to integrate LLMs without switching stacks.
- Unique (3/4): Good. While “AI” is common, focusing specifically on Voice and Real-time (ActionCable) in Rails distinguishes this from generic “How to use OpenAI API” talks.
- Urgent (4/4): “Multimodal” is indeed the current trend. The urgency is built into the fear of obsolescence (“LLMs are too big to ignore”).
- Ultra-specific (3/4): You list specific tools (RubyLLM, Stimulus), which is excellent.
- Critique: The “Pitch” section starts with “It’s 2026…” – if this is a prediction, it’s fine. If it’s a typo for 2025, we should fix it. To make it 4/4, the Abstract could hint at the specific use case you built (e.g., “an agent that takes pizza orders” or “customer support bot”) rather than just “AI voice agents.”
2. Features vs. Benefits
You have a tendency to list features. We can sharpen the copy by converting them to benefits.
| Current (Feature-focused) | Improved (Benefit-focused) |
|---|---|
| “It covers the building blocks of AI Agents…” | “Master the architecture of AI Agents so you can stop guessing and start building.” |
| “Discuss the differences between in-browser and server-side processing” | “Avoid costly architectural mistakes by choosing the right execution environment for your specific constraints.” |
| “Show how to use Stimulus for browser audio capture” | “Capture audio effortlessly using the Stimulus controllers you already know.” |
3. Title Suggestions
“Beyond CRUD” is a bit overused in the Rails community. Here are 5 options based on successful headline formulas:
- Direct Benefit: “Build Real-Time Voice AI Agents Without Leaving Rails”
- Contradiction/Challenge: “Real-Time AI in Ruby? Building a Voice Agent with Action Cable and Stimulus”
- How-to: “How to Architect Low-Latency Voice Agents in the Rails Ecosystem”
- Story/Experience: “I Built a Voice AI Agent in Rails: Here is the Architecture that Works”
- Curiosity: “The Stack You Already Own: Unlocking Multimodal AI with Rails”
4. Improvements & Questions
To produce the final, polished submission, I need a few details:
- Conference Name: (Or URL) – This allows me to check their specific themes and tone.
- Talk Format: Is this a standard 30-40 min talk or a lightning talk?
- Speaker Bio: You mentioned “working at a software boutique,” but I need your actual bio bullet points to ensure the submission highlights your authority properly.
- Clarification: In the pitch, did you mean “It’s 2026” as a “future scenario” opening, or was it a typo for the current year?
Once you provide these details, I will generate the final submission formatted for the CFP.

Here is a complete CFP submission tailored for Tropical on Rails 2026.
The proposal emphasizes the “Rails-native” approach to a trending topic (AI Agents), fitting perfectly alongside the conference’s high-level technical lineup (which includes speakers from GitHub Copilot and Shopify).
1. Talk Title
Option A (Recommended): Talk to Your App: Architecting Real-Time Voice Agents with Action Cable Option B (Playful): Silence the Python Envy: Building Native Voice AI in Rails Option C (Direct): Beyond Chatbots: Building Multimodal AI Agents in Rails Option D (Future-focused): Rails in 2026: The Architecture of Voice-First AI Agents Option E (Specific): From STT to TTS: A Rails Guide to Streaming Voice Agents
2. Abstract
It is 2026, and text-based chatbots are old news. Users now expect fluid, multimodal voice interactions, but most tutorials still point you to Python. In this talk, we will break that cycle by building a real-time AI voice agent using the stack you already love: Rails, Action Cable, and Stimulus. We will cover the full pipeline—from browser audio capture to server-side LLM processing—proving that Rails is the perfect home for the next generation of AI interfaces.
3. Description / Detailed Outline
The Pitch It’s April 2026. AI agents are everywhere, and the “chatbox in the corner” is no longer enough. As multimodal models become standard, users demand natural, hands-free voice interactions. For many Rails developers, this domain feels inaccessible or requires a complex microservice architecture in Python.
It doesn’t have to be that way.
In my work as a Developer Advocate at Codeminer42, I have helped teams ship production-grade AI agents—including an automated call center agent and a voice-driven product feedback collector. I discovered that Rails, with its robust WebSocket support (Action Cable) and modern frontend integration (Stimulus), is actually uniquely suited for these stateful, real-time flows.
This talk is a practical deep dive into architecting voice-first agents without leaving the Ruby ecosystem.
Outline
- The State of Agents in 2026
- Why “Multimodal” is the new standard.
- The shift from simple “context stuffing” to genuine Agentic workflows (Tool usage, Memory).
- Why Rails (and Ruby) is arguably better for orchestration than we give it credit for.
- The Anatomy of a Voice Agent
- The Pipeline: Speech-to-Text (STT) → LLM Brain → Text-to-Speech (TTS).
- Latency is the Enemy: Why standard HTTP requests fail for voice, and why streaming is non-negotiable.
- Building it in Rails (Code & Architecture)
- The Ears (Stimulus & Web Speech API): Capturing audio in the browser and streaming binary data over WebSockets.
- The Nervous System (Action Cable): Managing bi-directional streams for real-time conversation.
- The Brain (RubyLLM): Hooking into model providers (OpenAI/Anthropic) with tool calling capabilities.
- Case Studies from the Trenches
- Project 1: The Call Center: Handling interruptions and turn-taking (barge-in).
- Project 2: The Opinion Collector: Using structured outputs to save voice data as database records.
- Performance & Trade-offs
- Server-side processing vs. In-browser models (Transformers.js).
- Token optimization strategies to keep costs down.
- Conclusion
- The “Rails Advantage” in the AI era.
4. Target Audience
Intermediate to Advanced Rails Developers. Attendees should be comfortable with standard Rails architectures. No prior AI/ML engineering experience is required, but familiarity with the concept of an LLM API (like OpenAI) is helpful.
5. Learning Outcomes
- Architectural Clarity: Understand the specific components needed to build a voice agent (STT, LLM, TTS) and how they fit into a Rails monolith.
- Real-Time Skills: Learn to use Action Cable for binary audio streaming, going beyond simple chat updates.
- Tooling Awareness: Discover the Ruby-native ecosystem for AI (RubyLLM, LangChain.rb) effectively.
- Practical Implementation: Walk away with a recipe for building a “Talk to Data” feature using Stimulus and standard Rails controllers.
