Des brouillons d'e-mails par IA qui sonnent comme vous, dans Gmail et Outlook
ForthWrite lit les e-mails déjà envoyés pour créer un profil de voix et le rafraîchit environ tous les 50 messages captés, afin de suivre l'évolution de votre écriture.
Les utilisateurs Pro trouvent des réponses prêtes à l'ouverture de Gmail et peuvent traiter des dizaines de fils en parallèle au lieu d'écrire chaque message à la main.
Le ton s'adapte à la personne à qui vous répondez, et les relances, présentations et points d'avancement sont traités comme des tâches distinctes.
Versionnez et testez vos prompts en A/B, puis suivez le taux d'acceptation, la correspondance de voix et la répartition des intentions sur une courbe d'amélioration mesurable.
