## Overview

Letterbot AI is a browser extension built by the team behind letterbot.ai that turns Gmail's compose window into an AI-assisted writing surface. Instead of switching to a separate chatbot tab, you click a small robot icon in the compose toolbar, pick a tool, describe what you want to say, and the assistant produces a complete draft you can insert with one click. The extension is aimed at people who write a lot of email — sales reps, recruiters, customer support staff, job seekers — and want to cut down repetitive drafting time.

The extension bundles six distinct functions. "Write Email" generates a full message from a short prompt, "Smart Reply" reads the incoming thread and drafts a contextual response, "Subject Line Generator" proposes three options, "Email Summary" condenses long threads into bullet points, "Grammar Correction" fixes spelling and punctuation, and "Sales Email" produces persuasive cold outreach. Users can choose among formal, casual, friendly, polite, or respectful tones, and pick from ready-made templates such as follow-up nudges, meeting requests, thank-you notes, and resignation letters. Letterbot advertises support for English, German, Spanish, French, Portuguese, Croatian, Japanese, Korean, Simplified and Traditional Chinese, Arabic, Hindi, and Russian.

Pricing follows a freemium request-quota model: a free tier allows a handful of requests per day, while paid tiers scale up to 100 and 800 requests per day through the letterbot.ai website. The extension is independently developed and distributed — it is not an official Google or Gmail product, and the developer notes that data it handles (personally identifiable information, communications, and website content) is disclosed in its own privacy policy.

## Pricing & Plans

Freemium request-quota model: a free tier offers about 5 requests per day, with paid plans raising the cap to roughly 100 (Basic) and 800 (Professional) requests per day. Exact prices are listed on letterbot.ai.

## Key Features & Capabilities

- **Six email tools in one extension:** Write Email, Smart Reply, Subject Line Generator, Email Summary, Grammar Correction, and Sales Email cover the most common Gmail writing tasks from a single toolbar button.
- **13 languages and 5 tones:** Compose in English, German, Spanish, French, Portuguese, Croatian, Japanese, Korean, Chinese (Simplified and Traditional), Arabic, Hindi, or Russian, and switch between formal, casual, friendly, polite, and respectful voices.
- **Thread-aware smart replies:** When replying, Letterbot extracts the existing conversation so the AI understands the context before drafting a response.
- **Template library:** Start from ready-made templates including follow-ups after no reply, meeting requests, interview thank-yous, polite complaints, status updates, and resignation notices.
- **One-click insert into Gmail:** No tab switching: generate a draft and paste it straight into the compose window with the Insert button.

## Primary Use Cases

- **Cold outreach at scale (Sales reps):** Generate persuasive sales and follow-up emails quickly, adjusting tone per prospect while keeping a consistent professional voice.
- **High-volume candidate communication (Recruiters and HR):** Draft interview invitations, rejections, and status updates in bulk with correct tone and grammar.
