In short

GPT for Gmail is a Google Workspace add-on that integrates a multi-model AI assistant into Gmail's compose and reading panes. It is best for users who want to draft, translate, and summarize emails using various AI providers without leaving their inbox.

Best for

Pick GPT for Gmail if you live in Gmail and want a model-agnostic drafting and translation sidebar without leaving your inbox.

Skip if

Skip it if you need Outlook support, an API, or deep CRM-style automation beyond per-message drafting.

GPT for Gmail is a Google Workspace add-on from docgpt.ai that bolts a multi-model AI assistant directly into the Gmail compose and reading panes. It generates replies from context, rewrites tone, translates across 40+ languages, summarizes long threads, and ships a library of prebuilt prompts for common HR, sales, and customer-support scenarios. The add-on works on desktop Gmail as well as the iOS and Android apps.

The pitch that sets it apart from the dozens of other Gmail AI plugins is model choice: instead of locking you to one provider, it routes through GPT-4o, GPT-4, GPT-3.5 Turbo, Claude, Gemini, Mistral, and Perplexity, letting users pick the model per task. It is freemium, with basic generation free and heavier usage / premium models behind a paid tier. The 587K+ install base on the Marketplace suggests it is one of the more battle-tested options in the category, though reviews are modest in number.

Integration is sidebar-only inside Gmail, so it does not touch calendar, Drive, or non-Google mail clients. Personalization claims to learn from your writing style, but there is no public API and no self-hosting story — this is firmly a consumer/SMB productivity add-on, not an infrastructure piece.

Editor's take

A solid pick in a crowded niche, mainly because of the model-switching. The Gmail-only scope is limiting, and the polish lags behind first-party Gemini in Gmail, but the multi-provider flexibility and free tier make it a reasonable default for individuals.
