Description

Pi (short for 'personal intelligence') is a conversational AI companion from Inflection AI designed for empathetic, natural back-and-forth rather than productivity or search. It's aimed at everyday individuals who want a kind, supportive presence to talk through decisions, vent, learn topics, or practice conversation, and it differentiates itself with human-sounding voice options and a distinctly warm, non-transactional tone. It runs free across web, iOS, Android, and messaging apps.

SignalZen is an AI-powered customer support and live chat platform for small and medium businesses. Its AI answers from your website, files and help center and hands conversations to human agents. The platform includes a customisable chat widget, an AI copilot that drafts replies for agents, a public knowledge base, two-way translation and conversation summaries. Agents can reply from Slack, Microsoft Teams or Google Chat. Plans are monthly: Starter is $29 (up to 2 operators), Basic $49 (up to 5), Pro $99 and Business $199 (both unlimited operators), with a 30-day free trial and no permanent free plan.
