Google Sheets™ can now run AI in a cell, and it stops at 350 of them.

ReplyLabs has no cap. Point it at a column of leads, press Run, and it works across thousands of rows in the background. You are only charged for rows that succeed. A row that fails costs you nothing.


WHAT IT DOES

AI on every row
- Write one prompt and run it down the whole column. Reference your own data with {{first_name}} or {{company}} and it fills in per row. Use it to write cold email openers, score leads against your ICP, categorise companies, or clean messy data. Bring your own OpenAI or Anthropic key and pay the provider direct with no margin from us.

Bulk email verification
- Check an entire email list before you send. Catches invalid addresses, catch-all domains and role accounts, so your bounce rate stays low and your sending domain stays healthy. From $0.005 per address.

Website scraping and enrichment
- Give it a column of URLs and get back what those pages say. Company websites, LinkedIn company pages, pricing pages, anything public. Good for firmographic enrichment, competitor research, or gathering context before you write. From $0.005 per URL.

Flows
- Chain all three into one pass. Scrape a company's site, score the fit with AI, verify the contact's email and write a personalised opening line, in a single run across the sheet.


WHY NOT JUST USE A FORMULA

Sheets™ formulas run inside the spreadsheet, so they inherit its limits. The built-in AI function generates the first 350 cells and stops. IMPORTXML caps out around 50 calls per spreadsheet and fails on any page that needs JavaScript. Apps Script™ gives up after six minutes.

ReplyLabs runs off your spreadsheet, so none of those apply. Start a run on 40,000 rows, close the tab, come back later. Results write into new columns as they land.


WHO IT IS FOR

People who build lead lists in a spreadsheet: SDRs and sales teams, RevOps, lead generation agencies, recruiters, and founders doing their own outbound.

If your prospect list already lives in Google Sheets™ and you have been exporting it to a CSV, uploading it to an enrichment platform, then importing it back, this removes that round trip. No new interface, no seat minimum. Your sheet is the interface.


HOW IT WORKS

1. Install the add-on and open any Google Sheet™.
2. Open ReplyLabs from the Extensions menu.
3. Pick the column you want to work from.
4. Press Run.
