Composer AI vs WriteMail.ai

Composer AI is an email drafting tool for Gmail that uses an email thread and the user’s tone to prepare replies. Users connect Gmail, open a message, review and edit the generated draft, then send it. The homepage states that replies are produced in under three seconds. Composer AI is available on the web and as a browser extension, using Google APIs to read Gmail threads during composition. Its Free Beta Tier costs nothing and includes 20 draft compositions per account; users may request a manual limit increase. The privacy policy says thread content and prompts are sent to OpenAI, retained for up to 30 days, and not used for model training. Full conversation and email content is logged to LangSmith for debugging and service improvement, with deletion after 14 days. The service is experimental beta software without service-level agreements or uptime guarantees and advises against highly sensitive communications.

WriteMail.ai drafts and refines emails from a user's goals or key points, and can also generate replies from a pasted conversation and a reply goal. Users can adjust length, style, tone, mood, emoji use, and language. The site advertises generation in more than 30 languages and lists cold outreach, follow-ups, marketing, customer support, and personal email among its use cases. Browser integrations include a Chrome extension for Gmail, Firefox and Google Workspace Gmail extensions, and an Outlook add-in. The service prepares generated text for the user's default email client rather than sending messages itself. WriteMail.ai says generated messages do not touch its servers and personalized options are stored in a browser cookie. The free plan allows five AI emails per month. Paid monthly plans list 50 emails for Regular at $6.95, 150 for Basic at $11.95, and 500 for Pro at $19.95. The pricing note lists paid access from $5 per month billed annually. The Mail Assistant's real-time suggestions are limited to paid plans. Apps or access are listed for Android, iOS, macOS, Windows, web, and extensions.
