See how AI-generated emails and summaries accelerate communication workflows, from sales follow-ups to customer feedback analysis.
A sales rep finishes a product demo and asks the AI agent to draft a follow-up email. The agent feeds demo highlights, the prospect's name, and a professional tone into TextCortex's email generator. Within seconds, a polished email with subject line and body appears in the chat, ready to copy and send. Reps send follow-ups within minutes of ending calls, not hours later when the details fade.
A support manager receives a 2,000-word customer feedback email. Rather than forwarding the wall of text to the product team, they ask the AI agent to summarize it. TextCortex condenses the feedback into five key sentences covering the main pain points and suggestions. The product team reads a focused brief instead of parsing paragraphs, and the feedback loop moves faster.
A French-speaking customer submits a support inquiry. Your AI Agent generates a professional response email in French using TextCortex, maintaining the correct tone and language nuances. The customer receives a native-language reply. Your English-speaking support team handles international requests without translation delays.
