Agix turns Microsoft Excel and Google Sheets into an AI-powered workspace. Instead of switching between your spreadsheet and a separate AI chat tool, you type a question directly in the Agix sidebar — “Show me Q4 revenue by region” or “Predict next quarter’s churn based on the last 12 months” — and the AI reads your data, runs the analysis, and writes results back into your sheet. It is built for business analysts, finance teams, marketers, and anyone who lives in spreadsheets but has outgrown what formulas alone can do.Documentation Index

The problem Agix solves
Spreadsheets store data brilliantly but offer no way to think about it. Getting real insight typically means copying rows into a separate AI chat, pasting results back, opening a browser tab for live market data, and then building a deck in another tool entirely. Agix collapses that four-app workflow into one sidebar. Your data stays in the sheet; the AI comes to it.How it works
Agix registers as an Office Add-in task pane in Excel or as a browser extension sidebar in Google Sheets. When you send a prompt, Agix reads the selected range through the Office.js API, forwards the data and your question to the AI provider you have chosen, and streams the response back into the chat panel. If the AI produces structured output — a table, a set of values, a chart — Agix writes it directly to the target cells. The provider layer is intentionally flexible. You pick a model from the sidebar dropdown and supply your own API key. Requests travel directly from your machine to the provider, so your spreadsheet data never passes through Agix servers.Key capabilities
- Natural language interface — describe a calculation in plain English and Agix executes it on the selected range. No formula syntax required.
- Formula generation and explanation — ask Agix to write a formula into a cell (including XLOOKUP, SUMIFS, and dynamic array functions), or select any existing formula and ask what it does.
- Live internet data — fetch current stock prices, exchange rates, or competitor information and land it directly in your sheet.
- Charts — select a range and ask for a visualization; Agix picks the chart type or follows your instructions.
- Data enrichment and cleaning — parse unstructured text columns into clean rows, fix duplicate entries, and normalize date and number formats.
- Anomaly detection — flag metrics that fall outside their historical range when new data arrives.
- Pattern discovery and sentiment analysis — find correlations across large datasets and score text columns such as customer feedback or product reviews for sentiment trends.
- Stripe integration — connect Agix to Stripe to pull subscription tiers, payment histories, and user data directly into your spreadsheet for churn analysis, cohort LTV, and refund monitoring.
- Connectors — authenticate once to Salesforce, HubSpot, Google Analytics, Notion, or Airtable and keep any object or report refreshed on a schedule.
- Reports — generate PowerPoint decks, PDF reports, or one-page executive summaries from your processed data.
- Scheduler — run recurring AI tasks on a cron-style schedule so the spreadsheet keeps itself updated without manual intervention.
