Common questions from AI teams evaluating Graveiens AI as a data partner.
Graveiens AI provides human-in-the-loop data services for AI teams: data collection, data annotation and labeling, consent-backed multilingual voice data, transcription, LLM fine-tuning (SFT and RLHF) and LLM evaluation. The company is ISO 9001:2017 certified.
We work across text, image, video and audio in 25+ languages — covering data collection, annotation and labeling, transcription, and model-ready human feedback.
Pilots and projects are billed only for approved deliverables. Files pass internal QA and client review, and you are invoiced only for the files you approve — which keeps pilots near zero-risk.
25+ languages, with deep Indic coverage plus major Asian and European languages, for multilingual voice data, transcription and localization.
Yes. Voice datasets are built with explicit artist consent, metadata tagging and QA audit trails, delivered under an ISO 9001:2017-certified workflow.
Share your task, target language(s) and volume. We scope a sample batch, deliver it through our QA workflow, and you approve the deliverables before scaling.
