Type picks the shape (subject pattern, opening line, call to action), tone picks the voice (greeting and sign-off), and your key points carry the content. The measurements below come from the actual draft on screen.

• Two writers, one page. Write email with AI posts your brief to the free AI text API (text.pollinations.ai) and drops the answer back here; Local draft builds everything inside this tab.
• The free API is best-effort. The anonymous tier allows one email every 15 seconds - when the API is busy or limited the page falls back to the local draft automatically and says so, instead of hanging on a spinner.
• The local draft is a standard template. Your type, tone, recipient and name assemble into a subject pattern, greeting, bullets, call to action and sign-off - the same inputs always give the same draft.
• Type picks the shape. Ten types each carry their own subject pattern, opening line and call to action, from cold outreach to a friendly reminder.
• Tone picks the voice. The greeting (Hi, Hey, Dear), the sign-off and the closing line change with the tone you choose.
• Key points stay yours. The local draft lists them as bullets untouched; the AI version rephrases around them without changing meaning, facts or numbers.
• Checks are measurements, not a score. Subject length, greeting position, sign-off presence, echoed phrases and word count are counted from the draft on screen - there is no invented quality percentage.
• The 60-character subject line is a common guideline the Checks panel measures against - it is a count, not a promise about how anyone reads their inbox.
• The AI answer must look like an email - a greeting, a sign-off and at least a dozen words with a subject and body - otherwise the page treats it as unavailable, says so, and shows the local draft instead.
• Copy or download the result as plain text, subject line included - ready for your mail app. Your text travels to the API only when you press the AI button, and nothing is stored.
• Read-time is arithmetic: words divided by about 3.3 words per second, rounded up - the same rough pace a person skims a short note at.
