Opal - Visual Editor vs SignalBrain
A detailed comparison to help you choose the right AI tool for your workflow.
Opal - Visual Editor
Opal is a visual editor that allows users to build, edit, and share mini-AI applications. It facilitates the creation of custom workflows using only natural language, simplifying the process of building AI solutions. It is intended for users who need to automate tasks and build functional AI apps without requiring advanced coding knowledge. As the platform transitions, Opal's custom workflows are migrating to skills within Gemini. While active workflows will cease running after November 17, 2026, all workflow files remain stored and accessible in your Google Drive.

SignalBrain
SignalBrain provides governed AI infrastructure through the Titan runtime, enabling the deployment of AI models into production. It manages complex, consequential workflows by providing an independent execution boundary that controls the flow from probabilistic intelligence to deterministic action. The system executes a fully traceable, multi-stage request lifecycle: routing, evidence collection, policy enforcement, action, verification, decision, and final receipt. This mechanism ensures every action is governed and accounted for, generating a verifiable record of the entire process. This infrastructure is designed for companies already running AI agents but requiring stringent cost control per answer and enforceable accountability. It allows users to build trust through concrete mechanisms, including deterministic verification and inspectable evidence packets.
