You.com
You.com began as a web-grounded, citation-first AI search engine and has pivoted hard toward enterprise and agentic search APIs. As of April 2026 the old unlimited consumer free tier is effectively gone -- free users get a ~25-query Pro trial, with Pro at $20/mo and Max at $200/mo. The real strength now is the developer side: Search, Contents, and Research APIs with $100 in free credits, a free MCP endpoint (100 queries/day) for Claude Code and Cursor, SOC 2 certification, and no training on your data. It's a strong choice for building RAG and agents, less so as a casual consumer chatbot.
Pi
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.
You.com edges Pi on aggregate — 78 vs 56.
A web-grounded search engine that became an enterprise search-API company -- great for developers building RAG and agents, but its consumer free chat is now essentially a trial. 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.
