New to ReplyLabs? Our step-by-step guide walks you through installation, signing in, and running your first AI prompt in under two minutes.
Read the Setup Guide →Browse our knowledge base for detailed guides on AI prompts, web scraping, email verification, billing, team management, API keys, and troubleshooting.
Browse Help Center →Found a bug or something not working as expected? Let us know with as much detail as possible and we’ll investigate immediately.
Report a Bug →Go to the Google Workspace Marketplace and search for ‘ReplyLabs’, or use the direct install link we provide. Click Install and grant the requested permissions. Once installed, open any Google Sheet, go to Extensions → ReplyLabs → Open Sidebar. The sidebar appears on the right side of your spreadsheet. If you’ve previously installed ReplyLabs but don’t see it in the Extensions menu, try refreshing the page or clearing your browser cache.
ReplyLabs uses a prepaid credit system. Every new account starts with $20 in free credit — enough for thousands of AI prompts with affordable models like GPT-4o-mini. When your credits run low, add more from the dashboard at replylabs.io/dashboard/billing. Each operation (AI prompt, scrape, or verification) costs a fraction of a cent, and you can see the exact cost estimate before running any job. There are no monthly fees required — the Starter plan is entirely pay-as-you-go. Pro ($19/month) and Scale ($39/month) plans add features like bring-your-own API keys, higher team member limits, and priority support.
Yes, and this is one of the biggest advantages of ReplyLabs. On Pro and Scale plans, go to replylabs.io/dashboard/settings and add API keys for OpenAI, Anthropic, Google, DeepSeek, Mistral, or xAI. When you use your own keys, AI operations are free on ReplyLabs — you pay the provider directly at their standard rates with no markup. Your keys are encrypted with AES-256-GCM before storage and are never visible in the UI or our logs. You can remove them at any time.
Your spreadsheet data never leaves Google. ReplyLabs operates as a sidebar within Google Sheets — all sheet read/write operations happen through Google’s own infrastructure. When you run an AI prompt, only the specific cell content referenced in your prompt is sent to the AI provider you selected. We do not store, log, or retain your spreadsheet data on our servers. API keys are encrypted at rest with AES-256-GCM. Passwords are hashed with bcrypt. All data transmission uses TLS encryption. Our database enforces row-level security, meaning each user can only access their own organisation’s data.
Go to replylabs.io/dashboard/billing and click ‘Manage Subscription’. You can upgrade, downgrade, or cancel at any time. If you cancel, your plan remains active until the end of the current billing period. Your remaining prepaid credits never expire and can be used even after cancellation. If you want to delete your account entirely, go to Settings → scroll to the bottom → Delete Account.
ReplyLabs provides access to over 140 AI models from six providers: OpenAI (GPT-4o, GPT-4o-mini, o3, o4-mini, GPT-5), Anthropic (Claude Sonnet 4, Claude Haiku 4.5), Google (Gemini 2.5 Pro, Gemini 2.5 Flash), DeepSeek (V3, R1), Mistral (Large, Medium, Small), and xAI (Grok 3, Grok 4). Models are sorted by cost so you can easily find the best value for your use case. We sync new models automatically as providers release them.
Yes. Every ReplyLabs account belongs to an organisation. On the Starter plan, you can invite up to 3 team members. Pro allows 10, and Scale allows unlimited members. All team members share the same credit balance and API keys. Go to replylabs.io/dashboard/team to invite members by email. They’ll receive an invitation link to join your organisation.
First, try refreshing the Google Sheet page and reopening the sidebar. If the error persists, check your internet connection and try again. If you’re seeing a specific error message (like ‘Insufficient balance’ or ‘Rate limit exceeded’), the message itself explains the issue. For any other errors, visit our Report an Issue page at replylabs.io/report-issue and include the error message, what you were doing when it happened, and which browser you’re using. We typically respond within a few hours.
