Pi
General-purpose LLMs are not rated as companion apps. See methodology.
Inflection's 'personal intelligence', the general-purpose model that behaves most like a companion out of the box: gentle voice options, a warm check-in style, and zero cost. Development has slowed since Inflection's pivot, so it isn't improving the way the big LLMs are, but as a free, kind, always-available listener it still fills a niche nothing else does.

Memory benchmark
Not yet benchmarked. We run every companion through the same published memory test: the same facts planted at increasing distance, then probed. No score appears here until a real run exists, and every score links to its raw data. How the benchmark works.
Pi pricing
Current price: Free (Free). Prices in this category change quietly and often; any price change we record appears as a dated entry in the timeline below, so this page doubles as Pi's price history.
