Most AI chat tools struggle with real spreadsheets: they truncate large tables and lose the details that matter. Octo takes a different approach by living inside Google Sheets as a Chrome extension, querying the full dataset like a database and then acting on the results. It is built by data professionals with more than 15 years in the field and is aimed at people who want answers from their data without mastering spreadsheet formulas.
In practice, you add Octo to Chrome, connect a sheet in one click, and start asking questions. Octo cleans messy data automatically — filling gaps, repairing two-row and merged headers, skipping banner rows and handling broken-formula cells — then returns answers, summaries, trends and outliers, and guided follow-up suggestions. Beyond simple summaries it runs real statistics such as correlations, regressions, forecasts and distributions, and generates charts with an appropriate type chosen for your data.
Automation is where the Pro plan adds most value. You can schedule recurring analyses and data refreshes and have the results emailed on a daily, weekly or monthly cadence, or set alerts that fire when a cell crosses a threshold or the data changes. Octo works within Google's limited drive.file scope, so it only touches the spreadsheets you explicitly connect, and its data is never sold or used for advertising.
