AI in client communication: lessons learned What leading companies tried, what they learned, and our reflections

This page collects published articles on situations where companies used AI agents to automate too much of their written communication with potential clients, existing clients and consumers, and what came back. It also includes studies of where AI in writing works well. Each finding comes with its source and our take.

Part of the guide: Speech to text vs. AI automation vs. AI writing assistants

  1. Speech to text

    You speak, AI writes it down

    You say what you want to write. A speech-to-text tool such as WritingAnt turns it into well-written text instantly or within a few seconds. The content and the judgment stay yours.

  2. Agentic AI workflow

    AI writes by itself

    A workflow or AI agent writes and sends the text from data and rules. A person approves the draft, if anyone does.

  3. AI chat or writing assistant

    You and an AI iterate on one text

    You refine one text with an AI chat or writing assistant over several rounds, mixed with editing on the keyboard.

    An MIT study of generative AI in companies found that about 95% of pilot projects showed no measurable effect on profit and loss, and that purchased tools succeeded far more often than systems built in-house. The study defines success narrowly and has been criticized for it.

  • Klarna announced in 2024 that its AI assistant did the work of 700 customer service agents. In May 2025 its CEO said the company was hiring people for customer service again, and that customers should always be able to reach a person.

  • Alex Mashrabov, founder and CEO of the AI video company Higgsfield, said in September 2026 that probably over 60% of customer support requests, especially first-line ones, can be handled with AI, but that in B2B support AI automation just doesn’t work. Yet the company spends more than 10,000 dollars per employee per month on AI models, on average across its roles.

    A study by OpenAI’s economic research team and the Harvard economist David Deming, based on more than a million ChatGPT conversations, found that writing is the most common use of ChatGPT at work: about 40% of work-related messages in June 2025. About two-thirds of those writing messages ask ChatGPT to modify text the user already wrote (editing, critiquing, translating) rather than to create new text from scratch.

  • ZoomInfo, the US sales-data company, ran a one-month pilot of an AI sales development agent from the startup 11x in early 2025. ZoomInfo said the product “performed significantly worse than our SDR employees”, and it did not move forward. A former 11x employee told TechCrunch the startup was losing 70–80% of the customers that came through the door; 11x put its retention rate at 79%.

This is a forecast, not a measured result.

The findings show one pattern. Automation works for information. Where a relationship, a judgment or a liability is involved, the text should come from a person who stands behind it, and that person should be able to write it fast.
