Ask a yes/no question and receive a random Yes, No or Unknown answer
Enter starts the pendulum. While it moves, press the button again or Escape to reveal the selected answer. Stopping does not change it.
A random prompt for everyday reflection. Do not use it for medical, financial or legal decisions: the answer is not advice or a prediction.
The browser uses crypto.getRandomValues to draw an integer from 0 to 99. Values 0–44 mean YES, 45–89 mean NO, and 90–99 mean UNKNOWN: the configured weights are 45%, 45% and 10%. Rejection sampling discards the excess upper values of the 32-bit range before taking a remainder.
The question text and animation do not influence the draw. These are software weights, not the probability of an event. A new explicit start makes a new draw, so answers can differ.
This tab keeps the last answer through reloads until the next start. Existing history below stores up to 10 answers and times in this browser, without question text. Use its clear button to remove history and the saved answer. If browser storage is blocked, the tool works without saving.

The online pendulum is a random prompt for reflection on everyday choices. The program selects Yes, No or Unknown with weights of 45%, 45% and 10%. These are generator settings, not the probability of an event. The question text and animation do not influence the selection; the result is not advice or a prediction. Do not use it for medical, financial or legal decisions.
Enter one everyday yes/no question and press Start the pendulum or Enter. The answer is selected immediately; Stop and show answer or Escape reveals it without changing it. You can choose Without animation. The last answer survives a reload in this tab; Start a new draw makes another selection. Optional reflection questions let you write down your expectations and reasons. Question text and notes are not added to history.
Online Pendulum is useful when you want a quick online result, a symbolic hint or a starting point for reflection. It is suitable for personal use, comparison of options and a calm pause before a decision.
The result is informational and symbolic. It does not replace professional advice and should not be used as the only basis for medical, legal, financial or other high-stakes decisions.
