Millions of tokens of context

Most models forget after a few pages. Quasar holds entire codebases, full papers, and long conversations — all at once.

Features

Research, grounded in reality

GitHub integration

Connect repos, browse file trees, read source code, and search issues. Quasar understands your codebase in full context.

arXiv papers

Search papers, reference by ID, and extract full text from PDFs. Ground your work in real, peer-reviewed research.

Tool-augmented AI

The model decides when to call tools — reading papers, fetching code, or searching. Not just chat, but autonomous research.

Use Cases

Built for how you actually work

Codebase analysis

"Walk me through how auth works in this repo and find any security gaps."

Literature review

"Find recent papers on RLHF and summarize how they compare to DPO approaches."

Document analysis

"I uploaded a spec PDF — extract the API requirements and flag any inconsistencies."
