Numerous.ai
Numerous.ai adds an =AI() formula to Google Sheets and Excel that runs a plain-language instruction on each cell, useful for classifying, summarizing, rewriting, or extracting data at spreadsheet scale. Pricing starts at $8/month billed yearly (Personal, 1 million characters/month, single user) with a 7-day trial for $1, up to $24/month billed yearly (Pro, 5 million characters, up to 3 people, email support). The site's verdict is this is a narrow tool, but genuinely the cheapest, lowest-friction way to add AI to a spreadsheet workflow you already run, without paying for a whole automation platform.

Numerous.ai adds a single new function, =AI(), to Google Sheets and Excel. Write the instruction as the argument, point it at a cell or range, and it runs like any other formula, including filling down a column automatically.
Numerous.ai's formula slots into any cell exactly like SUM or VLOOKUP, except the argument is a plain-language instruction instead of a range reference. Drag it down a column and it reruns the instruction on every row, which is how it's used to generate ad copy variations, classify survey responses, or clean up messy user-submitted text at spreadsheet scale.

Why this beats copy-pasting into a chatbot
The alternative to a tool like this is copying a column of messy data into ChatGPT, writing a prompt, and pasting the results back, one batch at a time. Numerous.ai's formula runs the same instruction down an entire column automatically and fills down like any other spreadsheet formula, which is a meaningful time save for anyone who regularly cleans, tags, or summarizes data inside a spreadsheet instead of a dedicated database tool.
