Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
Coparenting calendar, custody tracking and court-ready records in one app
One calendar both parents can see, with hand-offs, swaps and overnights tracked; either parent can confirm a change in a tap.
Overnights and custody splits are tallied automatically into monthly reports, so the division of time is based on logged data rather than guesswork.
Timestamped, preserved chat with a pre-send tone scan that offers Balanced, Minimal and Polite rewrites; drafts and analysis are not stored with your messages.
In-app calls are transcribed and kept with custody records, alongside photo attachments, notes, shared files and an uneditable activity log.
