What an AI assistant can do — and where it stops
A clear look at the four kinds of AI assistant, what each is genuinely good at, and the work that still needs a person behind it.
An AI assistant is software that understands a request in plain language and acts on it. The category covers a wide range: consumer voice assistants like Siri and Alexa that handle timers and simple lookups; general chat assistants like ChatGPT and Claude that draft, summarize, and reason; and business AI assistants that connect to your calendar, inbox, and tools to carry out real work.
All of them share one limitation. An AI assistant does what it is asked, in the moment it is asked. It does not chase the vendor who never replied, notice that two commitments now conflict, decide which of them matters more, or take responsibility for the outcome. That last mile — judgment, persistence, and ownership — is still human work.
Marlow is built around that gap. You get a dedicated, handpicked human executive assistant, and an AI platform that removes the friction of working with one. You say what you need in plain language; the AI turns it into a clear, repeatable process; your assistant executes it and closes the loop. You get the speed of AI and the accountability of a person, as a single hire.
Four kinds of AI assistant
Consumer voice assistants — Siri, Alexa, Google Assistant. Excellent for hands-free commands, reminders, and quick facts. They do not touch your business systems and cannot be trusted with work that has consequences.
General chat assistants — ChatGPT, Claude, Gemini. Genuinely strong at drafting, summarizing, analysis, and thinking through a problem with you. They work inside a conversation: they will not act unless you are there, prompting, every time.
Business AI assistants and agents — tools that connect to your calendar, inbox, and CRM to automate defined workflows. Powerful when the workflow is stable and well specified, brittle when the work is ambiguous or changes week to week.
AI plus a human assistant — the model Marlow uses. AI captures the process and removes the delegation overhead; a trained person carries the work to completion and is accountable for the result. It is the only option on this list that can be given an outcome rather than a task.
What AI still can't be handed
- Chasing the person who never replied
- Deciding which of two conflicting priorities wins
- Noticing that something changed and flagging it
- Judgment calls with incomplete information
- Relationships with vendors, clients & your team
- Owning the outcome when something goes wrong
AI for the friction, a person for the outcome

AI assistant: FAQ
What is an AI assistant?
An AI assistant is software that interprets requests in natural language and acts on them — scheduling, drafting, summarizing, answering questions, or triggering a workflow. The term spans consumer voice assistants, general chat assistants, and business tools that connect to your systems and carry out defined tasks.
What is the best AI assistant for business?
It depends on the work. For drafting and analysis, a general chat assistant like ChatGPT or Claude is the strongest option. For fixed, well-defined workflows, a business automation tool works well. For work that needs judgment, follow-through, and someone accountable for the outcome, an AI assistant alone is not enough — you need AI paired with a real assistant, which is the model Marlow provides.
Can an AI assistant replace a human assistant?
Not today, and not for the work that matters most. AI is excellent at drafting, summarizing, and executing clearly specified steps. It does not exercise judgment on ambiguous calls, chase people who go quiet, notice that circumstances have changed, or take responsibility when something goes wrong. The effective pattern is AI handling the mechanical layer and a trained person owning the outcome.
How is an AI assistant different from an executive assistant?
An AI assistant is software that responds to instructions. An executive assistant is a person who owns an area of your working life — your calendar, your inbox, your travel — and works proactively without being asked. Marlow combines both: a dedicated human EA whose work is made faster and more durable by an AI platform.
Is my data safe with an AI assistant?
It depends entirely on the provider. Look for clear statements on whether your data trains their models, where it is stored, and who can access it. Marlow keeps each client's knowledge base isolated to that client, and the assistant working with you is employed by Marlow and bound by confidentiality terms.
How much does an AI assistant cost?
Consumer voice assistants are free. General chat assistants run roughly $20–$30 per user per month. Business AI tools vary widely by seat and usage. Marlow is a single flat monthly rate covering both a dedicated human executive assistant and the AI platform — see the pricing page for current rates.
