Numerous.ai

What it does

Numerous.ai adds a single, focused capability to Google Sheets and Excel: an =AI() formula that calls a GPT-style model directly from a cell, without requiring users to set up their own API key. It’s built around applying that formula consistently across many rows at once, which makes it well suited to tasks like classifying, summarizing, or generating text for large datasets.

Compared to broader tools like Formula Bot, it trades scope for simplicity — there’s no chat interface, scheduled reporting, or data-cleaning toolkit, just a reliable AI formula that works the same way in both major spreadsheet platforms. That narrower focus makes it a good fit for teams whose main need is applying AI text processing at scale inside a spreadsheet they already use.

Ideal users

• Spreadsheet users who want GPT-style text generation, classification, or summarization directly in cells, applied across many rows at once
• People who want AI formulas without setting up or paying for an OpenAI API key separately
• Teams processing large datasets (thousands of rows) that need consistent AI-generated labels, summaries, or extracted values

Who should avoid it

• You need complex data cleaning, scheduled reporting, or a chat interface for exploring data — Formula Bot covers more of that ground
• You already have Gemini or Copilot licensed and don't need a separate AI formula layer
• You need live data connectors to external databases rather than row-by-row AI text processing

Key features

• The =AI() formula for calling AI directly inside a Google Sheets or Excel cell, referencing other cells as input
• No OpenAI API key required — access is bundled into the subscription
• Optimized for applying AI functions across large datasets (reported to handle 5,000+ rows)
• Works across both Google Sheets and Excel with the same formula approach
• Supports common use cases like classification, summarization, sentiment tagging, and text generation at the row level

Pricing

Paid — $8-10/month (Personal plan, billed annually)

As of July 2026, numerous.ai/pricing lists a Personal plan at $10/month (billed annually, with a 7-day trial for $1) including 500,000 characters of AI input/output and 500 formula generations per month, and an Enterprise plan at $10/user/month (billed annually, up to 8 users) with 1 million characters per person, priority email support, and optional video onboarding. Cancelling keeps any remaining tokens.

Typical workflows

• A support team uses =AI() across thousands of rows of customer feedback to generate a one-word sentiment label for each row.
• A marketer applies an AI formula down a column of product descriptions to generate short social captions for each one.

Integrations

• Google Sheets add-on
• Excel add-in

Privacy & security notes

Numerous.ai's privacy policy states it does not use spreadsheet content to train AI models and does not access or store spreadsheet data outside of what is explicitly passed into an =AI, =WRITE, or =INFER function; requests are processed through OpenAI's API, which Numerous.ai states retains submitted data for 30 days for abuse monitoring before deleting it. Numerous.ai separately caches formula results in its own database to reduce repeat token usage.
