Key capabilities include:

• 250+ pre-made AI agents to cover common roles such as coding help, marketing content, tutoring, and planning
• Custom agent creation and training using provided data (files, links, and more) and configurable skills (including options like image generation and web research via Shards)
• Multi-model access across major providers, including OpenAI (ChatGPT), xAI (Grok), Meta, Google, Mistral, Perplexity, Anthropic, and DeepSeek, with unlimited conversations and messages
• Privacy-focused chat controls, including built-in encryption, private chats, and secure share links for conversation sharing

Pricing: Freemium, with a free plan (conversation depth limits and limits on AI agents added) and paid plans starting at $19/month; an Agent Plus annual plan unlocks full features and premium resources.

What makes it notable is the combination of a large agent library, no-code agent building and training, and an in-app ecosystem that includes an AI Apps Hub (with automatic updates) plus a Store for Shards and digital resources such as prompt packs, guides, templates, and SOPs.
