chat AI tools

Babylon 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 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.

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.
