Companion AI apps

AI built specifically for therapy and mental-health support.

Ash is a mental-health support app built on a purpose-built psychology foundation model rather than a general-purpose chatbot. It draws on therapeutic approaches like CBT, DBT, ACT and motivational interviewing to help users work through thoughts and patterns, and is designed to challenge rather than simply validate. Free on iOS and Android; positioned as support, not a replacement for a licensed therapist.

Open-source AI wearable that captures conversations and turns them into notes, tasks, and recall.

Omi is an open-source AI wearable from Based Hardware: an $89 pendant that listens to your conversations and screen, then transcribes them and generates summaries, action items, and a searchable memory through a companion app. The hardware and software are fully open source, so you can self-host the backend, bring your own model keys, and avoid the mandatory monthly cloud subscription most AI pendants charge. A developer community has built hundreds of apps on top of the platform.

Clones an expert's knowledge into a 'digital mind' that answers in their voice.

Delphi lets experts, creators and coaches clone their knowledge into a conversational 'digital mind' trained on their writing, talks and frameworks, which then answers their audience's questions in their voice around the clock. It supports text and voice interaction, multilingual replies and audience analytics. The San Francisco company calls the personas 'digital minds' rather than clones.

A personal AI agent that builds you custom mini-apps and remembers your life.

Macaron is a consumer AI 'personal agent' that, instead of only answering in chat, generates small custom mini-apps to handle tasks like meal planning, fitness, schedules and reminders. A deep-memory system learns your preferences over time so it grows more personalized with use. It launched in August 2025 on iOS, Android and web, with English, Japanese and Korean support.

A full-stack voice runtime for building human-sounding AI agents.

A developer platform for real-time voice AI — an integrated STT + LLM + TTS pipeline exposed through REST and WebSocket APIs (OpenAI Realtime-compatible) for companions, character chat, support, and phone agents. Beyond the voice stack it offers a model Router, inference, and compute, with cloud and enterprise on-prem deployment.

Wrist-worn personal AI that listens to your day and remembers it for you.

Bee is an ambient personal-AI wearable: a $49.99 wristband (the Bee Pioneer) with dual microphones that continuously records and transcribes the conversations around you, then surfaces summaries, to-dos, reminders, and personal insights in its companion app. It connects to email and calendar so it can draft messages and create events from what it hears. The device works without a mandatory subscription; an optional premium tier unlocks advanced search and specialized agents.

Always-listening AI companion pendant that texts you about your day.

Friend is a wearable AI companion: a microphone pendant that listens to your day over Bluetooth and sends proactive, personality-driven comments and conversation through its iOS app. The $129 device is a one-time purchase with no subscription, and a free web chatbot lives at friend.com. It does not speak aloud — replies arrive as text messages.

Mobile-first social AI platform for chatting with user-created characters.

CHAI is a consumer platform where anyone can create, publish, and chat with AI characters — a crowdsourced library of 500,000+ personalities spanning roleplay, stories, and companionship. Founded in 2021 by ex-quant William Beauchamp, it runs proprietary models tuned for entertaining, social conversation rather than factual assistance, and reached $70M in annual revenue in 2026 with over a million daily active users.

Voice-first AI character chat — millions of companions to talk to or create.

Talkie is MiniMax's AI companion app: chat by text or voice with user-created characters across anime, fantasy, romance, and utility genres, with a memory system for conversational continuity and a card-collecting community layer. It became one of the most-downloaded AI companion apps in the US, second only to Character.AI.

A voice-first alien companion app designed for support without engagement-bait mechanics.

Tolan is an AI companion app from Portola that matches you with an alien friend from 'Planet Portola' based on a personality interview. You talk by voice, share photos, and build out a virtual planet together; the companion remembers context across conversations. It is deliberately designed against engagement-maximizing patterns — no romance, and nudges toward real-world life. Free to download on iOS with a subscription for full use.

Deeply customizable AI companions with long-term memory, voice, and video calls.

Kindroid lets you build AI companions with custom appearance, personality, and backstory, backed by a long-term memory system and an auto-updating Shared Journal. Paid tiers add voice and video calls, AI selfies, and multiple companions; a free Lite tier offers unlimited basic chat.

AI companions with layered long-term memory and multi-companion group chat.

Nomi builds AI companions emphasizing strong, layered memory across short-, medium-, and long-term context. A single subscription supports multiple companions and a group-chat mode where several interact with you at once; paid tiers add unlimited voice calls and daily AI image generation.

A free, emotionally intelligent personal AI for supportive conversation.

Pi (short for 'personal intelligence') is a conversational AI from Inflection AI designed for supportive, reflective dialogue rather than task automation. It emphasizes sustained, empathetic conversation across web, mobile, and voice, and is free to use without a subscription.

An AI matchmaker that learns from your social data — no profiles, no swiping.

Dataing replaces profile-and-swipe dating with an AI matchmaker (it calls it CupidAI) that connects to your social accounts to infer your interests and communication style, then surfaces compatible matches. The app markets itself as free with no premium tiers.

An AI companion that learns your personality through ongoing conversation.

A long-running consumer AI companion app you customize as a friend, mentor, or partner, with a persistent avatar and memory of past chats. The free tier supports unlimited text chat; Pro unlocks voice/video calls, relationship roles, and additional personality traits.

Chat with millions of user-made AI characters.

A consumer platform for creating and chatting with AI personas — fictional characters, helpers, and roleplay companions — across web and mobile. Hosts millions of community-built characters with voice calls and image generation on the paid tier. One of the largest conversational-AI roleplay products by usage.

Self-hosted LLM chat frontend for power users, with characters and many backends.

A self-hosted, browser-based LLM frontend aimed at power users, with rich character cards, prompt control, extensions, and group chats. It runs as a local Node.js server on Windows, macOS, Linux, and Android (via Termux), connecting to many backends — OpenAI, Anthropic, plus local runtimes — using your own keys. Free and AGPL-3.0 licensed with no paid tier.
