Getting Started questions

How do I set up SheetMagic?
Install the extension from the Google Workspace Marketplace, then add your API key via Extensions → SheetMagic → Set API keys. Step-by-step guides are in the dashboard after you sign in.
What AI models does SheetMagic use?
SheetMagic supports the major AI models, including GPT-5.5, GPT-4o, Claude Opus 5, Claude Sonnet 5, Gemini 3.1 Pro and Gemini 3.5 Flash. For image generation, GPT Image 2, DALL-E 3, Gemini 3 Pro Image and Gemini 3.1 Flash Image are available. Which models you can pick depends on your provider: OpenAI, Anthropic, Google, Mistral, OpenRouter or Perplexity.
Do I need my own API key?
No. All paid plans include platform-managed API keys, so AI features work immediately. If you prefer, turn on BYOK (Bring Your Own Key) to use your own keys from OpenAI, Anthropic, Google, Mistral, OpenRouter or Perplexity for unlimited usage at provider rates.
Can I use my existing AI subscription (ChatGPT Plus, Claude Pro, etc.)?
No. Consumer subscriptions such as ChatGPT Plus and Claude Pro cover their chat apps and do not include API access. To bring your own key, create an API key on each provider's developer platform, where you are billed on actual usage.
Does SheetMagic work on mobile?
No. SheetMagic works in Google Sheets on desktop web browsers only. The Google Sheets mobile app does not support add-ons or custom functions. Use Chrome, Firefox, Safari or Edge on a computer.
Does SheetMagic work with Excel?
No. SheetMagic is built for Google Sheets on Google Apps Script and does not work with Microsoft Excel.
Can collaborators use SheetMagic on shared sheets?
Each person who runs SheetMagic functions needs their own SheetMagic subscription and API key. Collaborators on a shared sheet see the results of your formulas but cannot run SheetMagic functions without their own subscription.
How much will API calls cost me?
With your own key, cost depends on the model and how much text you send and receive. Each provider publishes its rates on its pricing page. For an estimate in SheetMagic terms, use the cost calculator.
Which API provider should I choose?
OpenAI is the simplest to set up and includes GPT-4o with web search. Anthropic gives you Claude models with web search support. Google offers Gemini models and native image generation through Gemini 3 Pro and Flash Image. OpenRouter gives you many models from multiple providers behind one key. Perplexity suits research tasks with built-in web search. Most people start with OpenAI or Anthropic.
