Pi (Inflection AI)
Inflection AI launched Pi in May 2023 as a 'kind and supportive' chatbot built on its own Inflection-2.5 model, raising $1.3B at a $4B valuation. In March 2024 Microsoft hired CEO Mustafa Suleyman, co-founder Karen Simonyan, and most research staff in a $650M licensing deal that left Inflection a hollowed-out shell. Pi still loads and answers messages, but new models are not in active training and the company pivoted to enterprise AI services.
Why Abandoned
Microsoft hired the founders and most researchers in March 2024 for $650M; Inflection pivoted to enterprise services. Pi still loads but is not the company's priority.

8 Best AI Chatbots Like Pi (Inflection AI) in 2026
Pi from Inflection AI was the warmest chatbot of 2023 — a calm, voice-first personal assistant from Reid Hoffman and Mustafa Suleyman — but Microsoft's March 2024 acqui-hire of the founding team stalled the consumer product and pushed millions of users to shop for a replacement. ChatGPT Plus at $20/mo with Advanced Voice Mode is the closest all-round match, Claude Pro is the best pick for thoughtful long-form conversation, Gemini Advanced is the strongest free tier for Google-ecosystem users, Character.AI is the winner for persona-driven roleplay, Replika is the best dedicated daily companion with persistent memory, Kindroid is the pick for privacy-first companion chat with lifetime memory, Poe is the multi-model gateway for anyone who cannot pick one, and Meta AI is the free voice-first assistant already built into WhatsApp and Ray-Ban smart glasses. These eight tools like Pi, ranked by use case with a price chart, capability matrix, decision tree, and migration playbook, cover every reason a Pi refugee is looking for a new home in 2026.
🪦 Other dead chat tools
Babylon Health
🔴Shutdown / DeadBabylon Health was a UK telehealth and AI symptom-checker company that went public via SPAC in 2021 at a $4.2B valuation. Its 'AI doctor' chatbot drew regulatory scrutiny from the UK MHRA over accuracy claims. After delisting from the NYSE and an attempted private rescue in 2023, the US subsidiary filed Chapter 7 bankruptcy in August 2023 and the UK operation went into administration. The brand and apps are gone.
Forefront AI
🟠Possibly DeadForefront launched in 2022 as a free playground for chatting with GPT-3.5, GPT-4, Claude, and image models in one interface. It briefly trended on Hacker News and Product Hunt and built a free-tier audience before paid alternatives like Poe and Perplexity captured the market. Forefront's chat app stopped accepting new signups in mid-2024 and the company pivoted toward enterprise data products. The original consumer site no longer functions.
