Brave Leo
Brave Leo is the AI assistant built into the Brave browser.

JAIS Chat
JAIS Chat is a bilingual Arabic and English conversational assistant launched by Core42, part of the UAE's G42 group. It runs on the Jais family of Arabic large language models developed by Inception with MBZUAI and Cerebras, and is built to handle Arabic dialects and cultural context rather than translated English.
- Genuinely Arabic-first training rather than an English model with Arabic bolted on
- Dialect handling targets the hardest and most practically important gap in Arabic AI
- Cross-lingual transfer from a large English corpus keeps reasoning ability intact
- Open weights allow independent evaluation and deployment inside a jurisdiction
- Smaller than the frontier models, and it shows on hard reasoning, coding and mathematics
- The surrounding product lacks the tools, file handling and integrations of mature assistants
- The site was not reachable during this check, so nothing could be confirmed on it directly
