What is the main difference between GPT for Sheets by DocGPT.ai and GPT for Work?

Both bring AI formulas into Google Sheets for bulk tasks. The main practical difference is pricing: DocGPT.ai uses a flat subscription (free tier, premium up to $29.99/month), while GPT for Work sells credit packs (from $29) that are consumed per task and model. Heavy continuous users usually save with a flat subscription; occasional users may prefer packs.

Do I need my own API keys with either add-on?

No in both cases — models are built in. Both also let you plug your own keys: DocGPT.ai via functions like GEMINI_CUSTOM, GPT for Work with a $1 per 1M token platform fee for custom keys.

Which models are supported?

DocGPT.ai's GPT for Sheets exposes GPT, Claude, Gemini, Mistral and Perplexity as separate formulas (=GPT, =CLAUDE, =GEMINI, =MISTRAL, =PERPLEXITY), plus =SERP for Google results. GPT for Work supports GPT, Claude and Gemini selected via its sidebar.

When DocGPT.ai’s GPT for Sheets is the better fit

You run bulk jobs regularly. A flat subscription beats per-credit billing when you generate content weekly — heavy translation or catalog work burns credit packs fast.
You want web-aware research in formulas. =PERPLEXITY() (live web answers) and =SERP() (raw Google results) make enrichment and SEO research native — plus Hunter.io and Google Maps functions for lead work.
You compare models per row. Five model families as plain formulas: run =GPT() and =CLAUDE() side by side and keep the better column.

When GPT for Work is the better fit

You also need Excel. GPT for Work ships for both platforms; DocGPT.ai is Google-Workspace-only.
Your usage is occasional. If you run a big job once a quarter, a $29 pack with 12-month validity may cost less than months of subscription.
Very large one-off jobs. Their infrastructure targets million-row runs.

Pricing math, honestly

A 10,000-row translation job: on a flat plan it costs your normal monthly fee; on per-task billing at “several dollars per 1,000 rows” (their own guidance for complex tasks) it can run $20–50+ per job. Flip it: if you do one 500-row job a month, packs win. Check the current numbers yourself — DocGPT.ai pricing, GPT for Work pricing.
