## GPT for Gmail™ | AI Email Assistant

GPT for Gmail lives where your email already is. After installing the add-on from the Google Workspace Marketplace and granting it access, a side panel appears in Gmail with options to generate a reply to the open thread, compose a fresh email from a prompt, rephrase what you have written, correct mistakes, or translate the whole message. The vendor states that the add-on works with ChatGPT, Gemini, Claude, Perplexity and Mistral models, so you can pick whichever engine suits the task without managing API keys yourself.

The main appeal is speed. Instead of writing routine responses from scratch, you describe what you want to say and let the assistant produce a draft you can edit. Template prompts cover common business scenarios such as HR replies, interview invitations, student and teacher communication, and client responses. There is also a summarization option for long threads, which is useful when you only need the essentials before replying.

Translation is a headline capability: the listing advertises support for more than 40 languages and dialects, making the tool popular with non-native English speakers who need polished business English. Pricing follows a freemium model - the add-on is free to install and core features are free, while advanced capabilities sit behind a paid plan handled on the vendor's own site. The listing has hundreds of thousands of installs and a 4.6-star average, which suggests it is actively maintained, with updates continuing through 2026.

**Pricing & Plans:** Freemium. The add-on is free to install and core features are free to use; premium features require a paid subscription purchased through the vendor's website. No API key is required for the built-in ChatGPT functionality.

- **One-click AI replies:** Open a thread, describe your intent, and generate a ready-to-edit reply inside Gmail's sidebar.
- **Multi-model choice:** The vendor advertises support for ChatGPT, Gemini, Claude, Perplexity and Mistral engines from a single add-on.
- **Rephrase, improve and correct:** Rewrite a draft for tone, tighten wording, fix grammar, or simplify an overly technical explanation.
- **Email translation in 40+ languages:** Translate incoming or outgoing messages across a long list of languages and dialects.
- **Template and prompt library:** Prebuilt prompts for HR, recruiting, teaching, support and client communication, plus custom instructions.

**Strengths:** Works directly inside Gmail with no copying and pasting between tabs; Covers several major AI providers, so you are not locked into one model; Translation across 40+ languages is genuinely useful for global teams; Free tier makes it easy to test before paying

**Limitations:** Requires granting an add-on access to your mailbox context; Premium capabilities are not fully spelled out on the marketplace listing; AI drafts still need human review for confidential or high-stakes email

## Missive

Missive was built around a simple observation: email was designed for individuals, but most businesses run on shared inboxes that several people need to work on together. Missive turns those inboxes into team workspaces. Every email becomes a conversation where colleagues can discuss the reply internally, assign ownership, and see who is handling what. Team inboxes, shared tasks, private notes, and tags replace forwarded messages and side-channel chat apps, keeping context attached to the message it belongs to.

The platform is a full email client as well, supporting Gmail and Google Workspace, Microsoft 365 and Outlook, IMAP, plus SMS and other channels. On top of that sits an automation layer: rules can handle repetitive routing and tagging tasks automatically, and integrations with more than 25 apps such as Stripe and CRMs pull extra context into the inbox. The AI assistant is positioned as a real assistant rather than a generic sidebar, gathering context from connected tools via MCP before drafting a reply.

Missive is popular with small and mid-sized businesses that live in email, including accounting, legal, real estate, logistics, and professional services firms. Customers include teams of 100-200 and above, and the company publishes customer stories, a status page, and a partner program for certified consultants.

**Pricing & Plans:** Missive offers a free trial so teams can invite colleagues and evaluate the product before paying. Paid plans are subscription-based per user, with tiers determined by team size and required features. Exact rates are published on the Missive pricing page.

- **Shared team inboxes:** Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
- **Internal conversation on emails:** Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
- **Tasks and workload visibility:** Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
- **Automations and rules:** Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.
- **AI assistant and integrations:** An AI assistant that gathers context from connected tools via MCP, plus integrations with 25+ apps including Stripe and CRMs.

**Strengths:** Turns shared inboxes into genuinely collaborative workspaces with internal chat; Combines email, tasks, automations, and integrations in one client; AI assistant pulls context from connected tools rather than acting as a generic sidebar; Strong fit for small and mid-sized teams that run on email

**Limitations:** Pricing is per-user and scales up with larger teams; The depth of features can be more than a very small team needs
