An answer you can defend when someone asks where it came from.
Every figure in the answer links back to a dashboard calculated from your rows. Filter it, sort it, compare it with the source. The explanation is written for you; the numbers are worked out, not written.
What you get
Everything you need, from one file.
Every row counted
Totals, averages, rates and rankings are calculated from the whole file, whether it has fifty rows or fifty thousand.
Answers in plain English
What changed, why it matters and what to check next, written for someone who has not seen the spreadsheet.
The unusual, flagged
Outliers, sudden jumps and categories that break the pattern are called out so you look in the right place.
Your rows stay yours
When you ask about a dashboard, only the calculated totals on screen go to the model, never the rows of your file.

Questions
Good to know.
Can AI analyse an Excel file accurately?
Yes, when the numbers are calculated rather than estimated. CTRON Loop calculates every figure from the rows of your file and uses AI to explain the results, so the totals always reconcile with your spreadsheet.
Is my data sent to the AI?
When you ask a question about a dashboard, only the calculated totals on screen are sent to the model, never the rows of your file.
Do I need my own API key?
No. Every plan includes managed AI within its limits. You can also connect your own key from OpenAI, Anthropic, Google Gemini, xAI Grok, Perplexity and others.
Which files work?
CSV and Excel files, including multi-sheet workbooks and exports with title rows above the header, plus connected Google Sheets.
Can I try it without signing up?
Yes. The try page runs on your own file or a sample with no account, card or API key.
Do it once. Run it again in one click.
Bring the file behind your next recurring task and see a real result in the next few minutes.
