LinkedIn automation API for leads, outreach and AI agents
Send messages, connection requests, reactions and comments, and run people or company searches — chained into conditional workflows up to five levels deep.
Search companies and people with advanced filters, pull employee lists, enrich profiles and return clean JSON for your CRM or data warehouse.
Each account runs in its own cloud browser with a matching device profile, human-like timing and custom mouse/typing behaviour.
An MCP server, agent skills, CLI and official Node.js SDK let assistants in Claude, ChatGPT, Cursor and similar tools call LinkedIn operations directly.
Turn any text, PDF, image or book into lifelike AI speech
Voices trained on large language models deliver lifelike delivery, while Content Aware voices read the text and adjust tone to fit the material.
Speak in over 90 languages and create a custom multilingual AI voice by uploading or recording your own.
Read PDFs, Word documents, ePub, web pages and images, and scan physical books with the built-in OCR camera scanner.
Turn long readings into AI podcasts, get instant recaps, analyse screenshots and equations, chat with your document and generate practice quizzes.
