This walks through Porter's Five Forces framework to analyze competitive dynamics in any industry. You get structured evaluation of competitive rivalry, supplier power, buyer power, threat of substitutes, and threat of new entrants, with clear criteria for rating each force as high, medium, or low. It's built for assessing market attractiveness before entering a space or when your competitive position shifts. The prompts push you to identify not just current state but trends and strategic responses. Pairs well with SWOT analysis when you need the full strategic picture, though forces analysis alone is often enough to spot whether you're fighting uphill.
