Formula Dog vs Numerous.ai

Formula Dog turns spreadsheet problems written in plain English into working Excel or Google Sheets formulas. You describe what you need, and the tool returns a paste-ready formula, often with a short explanation of how it works. The first five requests each day are free with no account required.

The product centers on a fine-tuned model trained on real spreadsheet formulas paired with human-written descriptions. That focus shows up in the output: fewer invented function names and syntax tuned for Excel, Google Sheets, VBA, regex helpers, and basic Airtable or Notion formulas.

It fits analysts, ops teams, and anyone who lives in spreadsheets but does not want to memorize every function variant. The site also ships a searchable cheat sheet, a playground with worked examples, and support for 12 interface languages.

Numerous.ai is a spreadsheet add-on that brings ChatGPT into Google Sheets and Microsoft Excel. You install the plugin, type formulas like =AI in any cell, and run language tasks across rows and columns without managing your own API keys.

Where standalone chat tools make you copy answers back into cells one at a time, Numerous.ai treats each row like a batch prompt and caches identical formula inputs so sheet refreshes do not re-bill the same query. That spreadsheet-first design is the trade-off: you get bulk generation and team prototyping inside Sheets or Excel, not a general-purpose chat window.

It fits marketers running campaign research, content teams batching social posts, students organizing research data, and product teams testing prompt structures before shipping features. The team is US-based in San Francisco, and both the Google Sheets and Excel add-ins are listed in their respective official marketplaces.
