Pi

FreeAI chatfree

Pi, from Inflection AI, is an empathy-first 'personal AI' tuned for supportive, natural conversation and voice rather than tasks. It's free with no paid consumer tier (now with some message caps), works across web and mobile, and has a uniquely warm, low-friction tone with eight voices. But after Inflection's founding team left for Microsoft in 2024 and the company pivoted to enterprise, Pi has sat in maintenance mode -- it still runs reliably, but the roadmap is uncertain and the feature set is frozen. It's lovely for companionship, but not something to build a workflow on.

Free · no consumer paid tier as of 2026 (some message/usage caps now apply). No public developer API for the Pi app. As of June 2026.

EDITORIAL VERDICT · BIGBANGINDEX

Kore.ai edges Pi on aggregate — 59 vs 56.

If your contact center handles 10k+ tickets a day and needs audit trails, Kore.ai is the answer -- everyone else should look elsewhere. Pi still wins for buyers who prioritise genuinely free, no card, no paid upsell. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
