Installing ReplyLabs
ReplyLabs is available on the Google Workspace Marketplace. To install it, open the listing and click Install, or in Google Sheets search for "ReplyLabs", or ask your Google Workspace administrator to install it for your domain. Click Install and accept the permission prompts. The permissions allow ReplyLabs to display a sidebar in Google Sheets, read and write data in the current spreadsheet, and make network requests to our servers. Once installed, you can access ReplyLabs from the Extensions menu in any Google Sheet.
Signing in for the first time
Open any Google Sheet and go to Extensions → ReplyLabs → Open Sidebar. The sidebar appears on the right. You'll see a login form where you can enter your email and password, or click "Sign in with Google" for passwordless access. If you don't have a ReplyLabs account yet, click "Create account" to sign up. New accounts receive $20 in free credit immediately. After signing in, the sidebar loads your available AI models and current balance.
Understanding your free credits
Every new ReplyLabs account receives $20 in free credit. This is real money that you can spend on any operation: AI prompts, web scraping, or email verification. With GPT-4o-mini, $20 gets you approximately 7,000 short prompts or 3,000 medium-length prompts. Credits never expire. You can check your current balance at any time in the sidebar (top-right corner) or on the dashboard at replylabs.io/dashboard/billing.
Navigating the sidebar
The ReplyLabs sidebar has five tabs at the top: AI Prompt (the main tab for running AI models), Scrape (for extracting data from websites), Verify (for email verification), Flows (view and run saved workflows), and Settings (manage your account and API keys). Below the tabs, you'll see your current balance and the selected AI model. The model picker dropdown shows all available models sorted by cost, so the most affordable options appear first.
