It connects through web sessions, your own API keys, or a cloud connection, and runs locally in the browser.
Its features include an answer engine with source citations, a Gmail assistant, style-matching writing tools, reusable and fine-tunable commands, price and page monitoring, scheduled commands, advanced automation, and integrations with Zapier, Make.com and n8n. It supports models including GPT-5.4, Claude, Gemini, DeepSeek, Perplexity, Llama and Grok, with AI vision and PDF summarization.
