You know what you need to say. Turning it into an email that sounds right is the part that eats twenty minutes. Type one line about the situation, pick the context and tone, and get a complete email — subject line, opening, body, sign-off — ready to copy into your mail app and send. This is not another inbox. It is the writing step that happens before you hit send. You steer the draft with real controls instead of guessing at prompts: seven contexts (work, sales, support, academic, job search, networking, personal), nine goals like follow-up, apology, proposal or reminder, ten tones from formal to empathetic, three lengths, six languages. Change one chip, regenerate, and the whole email shifts with it. WHAT YOU GET - A finished, send-ready email from a one-sentence brief — subject line included, no blank page to stare at - Wording that matches the moment: pick formal, persuasive, apologetic, grateful, urgent or empathetic and the draft changes with it - A reply to any message you paste in, written in the tone and goal you choose - Cleaner writing before it goes out: grammar and clarity review, instant rewording, and translation across six languages - 22 ready-made templates for meetings, cover letters, refunds, cold outreach and more — plus your own saved ones with reusable name placeholders - Everything you have written, searchable by keyword and context, exportable as CSV or PDF PERFECT FOR - Professionals who write the same awkward emails every week and want them done in a minute - Job seekers sending cover letters, interview follow-ups and referral requests - Sales and support teams that need outreach, follow-ups and escalations to land right - Anyone writing in a second language who wants to sound fluent and appropriate WHY NOT JUST USE A CHAT APP? Because you would retype the same setup every time. Here your context, tone, goal, length and language are one-tap controls, your best emails are saved as reusable templates, and your history is right there to search — instead of scrolling back through a chat thread hunting for the version that worked. PRIVACY No account, no ads, no tracking. Your drafts, templates and history live in the app on your device. Sending text to the AI is opt-in and you approve it before anything leaves your phone. Voice dictation uses the microphone only while the recording screen is open. FULL ACCESS Full access unlocks unlimited email generation, all ten tones, all six languages, smart reply, grammar check, paraphrase and translate, voice dictation, and unlimited history and custom templates. Choose weekly, yearly, or a one-time lifetime purchase. AI drafting connects to OpenAI using an API key you add once in Settings. Write the email you have been putting off — open the Compose tab, describe it in one line, and send it in the next minute.
