The AI browser that reads between your tabs
Starts the day with a consolidated view of your calendar, inbox and key links so you know what is coming before work begins.
Ask once and Dia searches open tabs along with connected Slack, Notion, Teams, GSuite and other tools to answer with full context.
Requests for a deck or a summary come back as presentable slides and shareable reports rather than raw chat text.
Surfaces where work is actually happening, like a specific pull request or spec draft, so one click lands you in the right place.

Track, evaluate, and ship AI models and agents in one connected environment.
Log metrics, losses, and media from training runs and compare them side by side in interactive charts to spot what actually improves your model.
Run automated hyperparameter sweeps and visualize parameter importance so you can converge on better configurations faster.
Version datasets and model artifacts, track lineage, and promote models through a registry from training to production.
Build, log, and evaluate LLM prompts and applications, with tracing and evaluation tools grouped under an LLMOps workflow.
