Who it is for
Stop rebuilding context one prompt at a time
For anyone whose source material is too large, connected, or detailed for a short chat window.
Splitting a large source into tiny fragments makes it harder to compare ideas and preserve the full picture. Long Context keeps more relevant material available in the same workflow.
Codebase understanding
Trace relationships across more files before planning a change.
Mode switching
Move from Long Context to Smart, Fast, or Vision without changing products.
Practical examples
How this fits into real work
Compare reports
Extract themes, differences, risks, and unanswered questions across multiple sources.
Understand a repository
Map modules, dependencies, conventions, and likely impact areas before editing.
Study a textbook
Build chapter summaries, concept maps, and revision notes from connected material.
Clear by design
Choose a brain. Keep the workspace.
- No user-supplied API keys or model downloads
- Switch modes as the task changes
- Long-context and vision available in the same interface
- Use the direct-answer option when standard modes become overly cautious
