TubeSplit

TubeSplit is a companion tool to YouTube's native Test & Compare feature, designed to solve a key problem: YouTube Studio doesn't preserve thumbnail test data or provide a unified view across multiple experiments. The platform acts as a persistent archive and analytics hub for A/B/C testing workflows.

The tool works by integrating with your YouTube channel through a Chrome extension that automatically pulls Test & Compare analytics from YouTube Studio into a centralized dashboard. Once connected, you can view all past and current thumbnail tests in one place, track performance trends over time, and compare results across multiple experiments without manually digging through YouTube's interface. This is particularly valuable for channels running frequent tests, as YouTube Studio doesn't retain historical test data long-term.

Beyond data aggregation, TubeSplit offers AI-powered features including automatic thumbnail generation and title suggestions to streamline the testing process itself. Creators can generate thumbnail variants directly in the tool, then easily download them for use in YouTube Studio tests. The platform emphasizes speed—one-click downloads and simplified experiment setup to reduce the friction of running iterative tests.

This tool is built for YouTube creators and channel managers who treat thumbnail optimization as a core growth strategy. It's most valuable for channels running frequent A/B/C tests and needing to track performance patterns over weeks or months. The free trial and unlimited test storage lower the barrier to entry. However, the tool is tightly tied to YouTube's ecosystem and requires active use of Test & Compare; it won't help creators who aren't already running native YouTube experiments.
