AI assistants for founders: what each one is good at

The AI assistants worth knowing as a founder fall into a few kinds, and each is good at one job: chat assistants for thinking and writing, assistants inside your email and calendar, meeting note-takers, scheduling assistants, assistants you text, and assistants that keep up with people across your apps. Most founders end up using two or three. The useful question is not which one is best, but which job is costing you the most time.

What kinds of AI assistant are there?

It helps to sort them by the job they do rather than by brand. Many products now overlap at the edges, but each still has a centre of gravity.

Which AI assistant is best for thinking, writing and research?

A general chat assistant is the right tool here, and the three most founders know are ChatGPT from OpenAI, Claude from Anthropic, and Gemini from Google.

All three are good at the work founders do in long stretches: drafting an investor update, pressure-testing a pricing page, summarising a contract, or researching a market before a call. They have also grown beyond the chat box. ChatGPT can connect to Gmail and Google Calendar so it can answer questions about your own email and schedule. Claude connects to apps such as Gmail, Google Calendar, Slack and Google Drive, and can produce documents, spreadsheets and slides from them. Gemini works with Gmail, Calendar and Keep, so you can ask it to summarise emails from certain people or find something in your inbox.

Where they stop is the shape of the work. You open them, bring a task, and get a result. They are excellent at the task in front of you. They are not designed to sit across your WhatsApp, LinkedIn and email and notice who has been waiting on you for three days.

Which of the three suits you is mostly taste and which tools you already live in. If your company runs on Google Workspace, Gemini is close at hand. Many founders keep one as a daily thinking partner and stop there.

Which AI assistant is best for a founder's inbox?

If your inbox is the problem, the assistant built into your email client is the first thing to try, because it works where you already read.

• Gemini in Gmail can draft and reply to emails, summarise long threads, and answer questions from your inbox or Drive. It comes with Google's AI Pro or Ultra plans for personal accounts, and with Workspace plans for business.
• Copilot in Outlook can summarise an email thread, with citations back to the emails it used, and draft a message from a prompt that you then edit and send.
• Superhuman is an email app built for speed, with AI writing that aims to sound like you.

These save real time on reading and replying. Their limit is that email is only one of the places people reach you. An investor who emails, then follows up on WhatsApp, appears as two separate threads in two separate apps, and the email assistant only sees half of it.

Which AI assistant should take notes in meetings?

A dedicated note-taker, if you spend a lot of the week on calls. This is one of the clearest wins in the whole category.

• Granola transcribes from your computer's audio, so no bot joins the call, and turns your rough notes into a clean write-up with action items. It runs on Mac, Windows, iPhone and Android.
• Otter transcribes meetings, captures action items and lets you ask questions across them. It can join Zoom, Google Meet and Microsoft Teams calls, or record from a desktop app.
• Fathom records, transcribes and summarises meetings, works with Zoom, Google Meet and Teams, and can sync notes to CRMs such as HubSpot and Salesforce. It has a free plan.

The choice between them often comes down to whether you are comfortable with a bot in the call, and where you want the notes to end up. Where they all stop is the end of the meeting. The note says you promised to send the deck by Friday. Making sure it goes, and chasing the reply, is still on you.

Which AI assistant is best for scheduling?

A scheduling assistant takes the back-and-forth out of finding time, and there are two main approaches.

Reclaim works on your Google or Outlook calendar and schedules focus time, tasks, habits and breaks around your meetings, moving them as the week changes. It suits founders whose calendar is full and who need protected time to build.

Calendly is known for booking links, and now has an AI scheduling assistant called Callie, in beta, that you copy into an email thread to coordinate a time for you. It also has a note-taker for the meetings it books.

Both are good at time. Neither is meant to keep the wider conversation with a person moving, such as sending the document they asked for or following up after the meeting.

What about an assistant you can just text?

Some assistants live in your messages app instead of a website, which suits founders who are on their phone most of the day.

Poke is an assistant you message through Messages, WhatsApp or Telegram. You can connect your email and calendar, ask it to search or draft emails, and have it set reminders from a text or voice message.

The appeal is speed: no app to open, just a text. The limit is similar to the chat assistants. You still bring each task to it, and its focus is helping you, rather than keeping up with the people who are waiting on you.

Which assistant keeps up with people and follow-ups across apps?

This is the job most founders still do by hand. The same person writes by email, then WhatsApp, then LinkedIn. Every tool above helps with one piece of that, and none of them holds the whole thread with that person.

An assistant built for this job keeps up with the people you hand to it across all your apps, knows where things stand with each of them, and has the next message ready. It suits the conversations that matter but do not need you personally each time: scheduling, sending what someone is waiting on, chasing a reply, keeping a candidate or a supplier moving.

Founders still handle their most important relationships themselves: the co-founder, the lead investor, the first big customer. Those conversations carry judgement and trust that are worth your own time, and a good assistant leaves them to you while clearing the rest.

Where does Mira fit?

Mira is that last kind, and it is the one that changes a founder's week the most. It is autonomous: you text it, and it works inside Gmail, Outlook, WhatsApp, iMessage, LinkedIn, Slack, Google Calendar, HubSpot and Attio, keeping your conversations moving whether you are there or not.

Every other tool on this list helps with a piece of the job when you open it. Mira holds the whole thing. Hand it an investor, a candidate or a customer and it owns that relationship: it knows the history across every app, follows up when things go quiet, and has the next message ready. It reads every conversation and only brings you the ones that need you. It briefs you every morning, preps you before every meeting, and wraps up each evening with what moved and what is waiting. Ask once for a repeat job, such as a CRM update after every call, and it is done every time.

Nothing is sent as you until you say yes. Your messages are never used to train AI models; everything Mira reads is encrypted in transit and at rest with AES-256, and Mira is CASA Tier 2 certified. Mira is free to start.

How should a founder choose?

Start with the job that costs you the most time this month.

• Thinking, writing and research: a general chat assistant.
• Too much email in one inbox: the assistant inside your email client.
• Back-to-back calls: a meeting note-taker.
• A calendar that runs you: a scheduling assistant.
• Too many people to keep moving, across too many apps: Mira.

For most founders that last one is the job that eats the week, which makes Mira the one to start with. Add the others as you need them; two or three well-chosen assistants beat a stack of tools that each need watching.
