Visual line-by-line diffs
Red strike for removals, green for additions. Side-by-side on demand. Works on any tracked page.
Every other tool pings you when a page updates. SpyGlow shows you the old line and the new line, scores how much it matters, and hands you a drafted response before you finish reading.

Change detection tells you that a page changed. SpyGlow gives you exactly what changed, why it matters strategically, and an importance score so cosmetic tweaks stay quiet.
