Dia AI Browser Integrates Popular Arc Features

November 04, 2025
The Browser Company is adding Arc's most-used features to its AI browser Dia, including sidebar mode and pinned tabs, while testing deeper Atlassian integrations.

The AI browser Dia is incorporating several of Arc’s most popular features as part of its latest updates. The move was confirmed by The Browser Company founder Josh Miller, who said Dia will bring back Arc’s “greatest hits,” such as the sidebar mode, while introducing AI-native capabilities like memory and agents.

The update follows The Browser Company’s acquisition by Atlassian for $610 million. The company continues to operate independently but is now developing integrations with Atlassian’s Jira and other productivity tools. Early users have already seen features like Focus Mode, vertical tabs, pinned tabs in grid view, and automatic picture-in-picture for Google Meet sessions.

Dia’s team is also testing pinned tabs and exploring how to adapt Arc’s Spaces — separate browsing areas with dedicated themes, favorites, and histories — for the new browser. Future updates may include swipeable profiles and search enhancements inspired by Arc Search for the mobile app planned in 2026.

Miller said Dia’s architecture is designed for improved AI performance, security, and speed, while reducing the complexity that limited Arc’s wider adoption.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
