Composer AI vs MailSome

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.

MailSome is an AI email writer for Gmail, available through a browser extension and the web. It reads the current email thread and places contextual suggestions in Gmail’s reply field. You can choose neutral, friendly, critical, formal, or casual tones, then correct, rephrase, or translate text. Replies are available in German or English, while the PRO plan is described as multilingual. The free service provides five emails each day without signup. A 14-day PRO trial is available without commitment. PRO costs €9 a month and includes unlimited AI replies, multilingual support, updates, and priority support. The homepage says registration and storage are not required and describes user data as private and secure. MailSome appears automatically in Gmail after installation. It is made by Campus IT Consulting GmbH in Grünwald, Germany.
