Before you send

  • Choose a local model, remote model, Constellation model, or Autopilot.
  • Select a chat mode and answer style, add chat instructions, and set reasoning control when the model supports it.
  • On iPhone, iPad, or Mac, attach PDFs from the Files interface and wait for the inline indexing status to finish before asking about them. Supported EPUB and text attachments can also be indexed, and you can select an existing dataset for retrieval.
  • Arm only the chat tools you want available for the next turn.
  • Open the chat status drawer to review capabilities, reasoning, Autopilot, MCP, and the current context budget before sending.

Read the chat status drawer

  • Compact capability controls keep the active chat features together.
  • Reasoning and Autopilot status show how the next turn is configured.
  • MCP visibility makes connected tool availability easier to inspect.
  • The detailed context-budget meter shows how much of the model’s window is planned or occupied.

Keep longer conversations responsive

As a conversation grows, Noema can compact older context so the active thread remains useful without making every turn carry the full history unchanged. This reduces the chance that a long chat stalls as it approaches the model’s context limit.

Message actions

ActionWhat it does
BranchStarts an alternate continuation from the selected point.
RegenerateRuns the response again with the active route and settings.
Try ModelRetries the turn with another compatible model.
BookmarkSaves the answer for later review.
Pin to Private ScratchpadKeeps selected material in the private scratchpad.
AuditOpens supporting runtime, citation, receipt, and diagnostic detail.
RerouteRetries an Autopilot answer through a different allowed route.

Find and review earlier work

  • Chat Recall searches past conversations when enabled.
  • Bookmarks collect saved responses without inventing folders or notebook collections.
  • Raw output exposes the model’s unprocessed response when you need to diagnose formatting.
  • Runtime information shows model, route, token, timing, and context details available for the turn.

Evidence and receipts

Web and dataset answers can include cleaner citations, evidence controls, retrieval receipts, and source detail. Numbers and complex formulas use sharper math rendering. Open the source when accuracy matters; a citation shows what material was provided, not that the model interpreted it correctly.

Export and diagnose

  • Export packs collect the conversation and selected supporting material for handoff or review.
  • Diagnostics expose route failures, model events, retrieval behavior, and tool execution without relying on nonexistent message deletion or duplicate controls.
