CTRON Loop flow: Document to Brain to Router to Agent to Output

One engine. Four ideas.

AI Router

One command box. The router classifies each task and sends it to the right model - cheap where it can, strong where it matters.

Company Brain

Upload your documents and spreadsheets once. Every output is grounded in your real company context, not generic AI.

Task Packs

Pre-built templates for documents, communication, spreadsheets and operations - 12 task types, one engine.

Loops

Turn work you repeat into a saved loop and re-run it in seconds with new inputs.

How it works

1

Add your knowledge

Upload PDFs, DOCX, TXT, CSV and XLSX. We chunk and embed them into your Company Brain.

2

Connect your keys

Bring your own OpenAI, Anthropic or Perplexity keys. We never bill you for AI usage.

3

Run a task

Describe what you need. Get a structured, on-brand output grounded in your context.

4

Save as a loop

Keep the ones you repeat and re-run them whenever you need.

Built for operators, not prompt engineers

CTRON Loop is for solo operators and small teams who repeat the same work every week - proposals, reports, client updates, document reviews. It works with your company context, so the output is usable, not generic.

  • - Your data stays in your workspace (row-level isolation).
  • - Your AI keys, your provider account, your control.
  • - Fast: most tasks complete in under 30 seconds.
