Onboard Your Team
We set up your company, teams and training scenarios in minutes.
Pick a Scenario
Sales call, complaint, negotiation, upselling and more.
Talk to the AI Customer
Have a real spoken conversation — the AI listens, objects and adapts.
Get Instant Feedback
Scores and coaching on every skill, right after the call.
Feedback your team can act on
After every call, employees get 0–100 scores, what they did well, what to improve, better example responses and the next scenario to practise.
AI Coach: You handled the concern professionally, but moved to pricing too quickly. Practise Objection Handling next.

Real practice against realistic AI customers, with objective scoring after every session.
Realistic AI customers
AI personas that ask questions, raise objections and show emotion.
Dynamic conversations
No fixed scripts — the AI adapts to every response.
Objective scoring
0–100 scores on clarity, confidence, empathy, objection handling and more.
Secure & consented
Sessions recorded with consent and stored with access controls.
Practice anywhere
Employees train remotely, on their own schedule.
End-to-end platform
Training, evaluation, analytics and reporting in one place.
Built for customer-facing teams
We help teams that live on the phone improve with every simulated call.
Consent first. Always.
How training sessions and recordings are handled responsibly — from the first word to final report.
Informed consent
Contributors read and sign a consent agreement explaining how their voice will be used before any recording.
Purpose-limited collection
We record only what the project needs and strip unnecessary personal details from metadata.
Secure storage
Recordings are stored with access controls and shared only with the client who commissioned them.
Right to withdraw
Contributors can ask questions or withdraw consent by contacting us, as set out in our policy.
Languages we cover
Train your teams in the language they serve customers in — with more added for every rollout.
Questions, answered.
What clients and contributors ask us most.
What kinds of AI data do you deliver?
Speech recordings and transcription, text and conversational data, image and video annotation, and quality evaluation — across many Indian and global languages.
How fast can a project start?
Most pilots start within 1–2 weeks after scoping. Book a meeting and we'll share a timeline and sample data.
How do you handle contributor consent?
Every contributor gives informed consent before recording, and personal identifiers are separated from delivered data wherever possible.
Can I work remotely as a contributor?
Yes. Contributors work from anywhere with a smartphone or laptop and are paid for work that meets project guidelines.
Where can I learn how my data is used?
Read our Privacy Policy and Data Consent Policy, or ask the Policy Assistant for a plain-language answer.
