Everyone now thinks with the same AI, which quietly flattens originality into a confident average. DotSpark is the mirror that keeps your judgment yours. Connect it once and your assistant reads your Thinking Shield at the start of every conversation and follows it for the whole session: challenge before agreeing, make you reason first, keep your ideas and voice yours. As you work, it captures the residue of your thinking — insights ("dots"), connections across them ("sparks"), and a periodic read of how you think — into your personal DotSpark graph. Nothing is sent back to make the AI smarter about you; every signal points at your own self-knowledge.
