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.

Curate, annotate and QA multimodal training data in one governed workspace
Annotate image, video, audio, text, documents, medical imaging, pathology, geospatial, sensor and tabular data in one governed workspace rather than stitching together separate tools.
Bring your own models into the labeling loop for pre-annotation, segmentation and object tracking, with multiple model stages combined with human review before anything is approved.
Consensus, Quality Gate and expert review stages validate labels against hidden answer keys to keep training data reliable — Unitlab cites 99%+ QA-backed accuracy.
Build dataset versions as data evolves, assign tasks, track changes and keep annotation history and label lineage auditable across the AI lifecycle.
