Built this to add a persistent toggle for filtering Google results to pre-2023. Yes, you can use date parameters manually, but having a one-click toggle has proven surprisingly useful for technical research.

Implementation details: - Modifies search URL parameters for date filtering - No analytics/tracking - Lightweight, just handles date toggling - No background processes

Been using it for my own development work. Posted on r/programming where other developers found it useful for filtering out AI-generated technical documentation and finding original solutions.

Happy to answer any technical questions about the implementation.
