AI-powered customer conversation platform for B2C messaging at scale
Bring WhatsApp, TikTok, Instagram, Facebook, Telegram, email and web chat into one shared inbox so no customer thread gets lost between apps.
AI agents qualify leads, answer routine questions, route to the right teammate and follow up automatically when conversations go quiet.
Track tags, custom fields, lead status and lifecycle stage per contact, and move deals through a pipeline without a separate CRM.
Reach thousands of customers with one message, and capture new leads directly from social ads and website links.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
