[H2] Algoroo
Algoroo is a Google algorithm tracking tool developed by DEJAN. Our system monitors carefully selected keywords and looks for fluctuations. Both negative and positive movement is added up to create a single SERP flux metric we call “roo”. High roo value indicates a high volatility in Google’s search results. Low roo value is usually displayed on an ordinary day, unlikely to be affected by any algorithmic changes at Google.

[H2] Reverse Prompter Model
We fine-tuned Google’s Gemma 3 (270M) to reverse the typical LLM workflow: given an AI-generated response, the model reconstructs the most likely prompt that produced it. We generated 100,000 synthetic prompt-response pairs using Gemini 2.5 Flash, trained for a single epoch on a consumer GPU, and built a Streamlit app that sweeps 24 decoding configurations to produce ranked prompt candidates.
