    Sabi vs Martin is a choice between a personal Jarvis and a business assistant with a team behind her. Martin AI is a voice-first personal assistant you call, text, or email; Sabi is an AI executive assistant that runs a business owner's admin over text. This comparison covers price, integrations, reviews, and support as of September 2026.

    What is the difference between Sabi and Martin AI?

    Sabi is an AI executive assistant for founders and owners: she triages your inbox, books meetings, chases leads, and reports on your numbers from a text thread. Martin is a personal AI agent that calls you, texts you, and manages your calendar, inbox, reminders, and to-dos.

    Martin's home page sells it as "Your personal AI agent" and its App Store listing calls it "Your AI like Jarvis." Its founders' seed announcement says they want Martin to know "your morning routine, your travel plans, your kid's soccer schedule." That is a life assistant, and a good one.

    We built Sabi for the business half of your day. You text her "send last month's Stripe revenue and follow up with the three leads from Tuesday," and she does both, inside the tools where your money moves.

    Martin AI is a voice-first personal assistant for your day; Sabi is an AI executive assistant for your business, backed by a human on every support ticket.

    How much does Martin AI cost compared to Sabi?

    Martin AI pricing runs $21 to $49 per month, and Sabi retails at $295 per month; a founding member special running now brings Sabi's price down significantly. The gap reflects the buyer: Martin prices like a consumer app, and Sabi prices against the cost of hiring help for a business.

    A full-time US executive assistant costs $84K to $144K a year plus benefits, so both sit far below that line. Martin's numbers come from its pricing page and Martin Pro launch post as of September 2026; its site still shows a Black Friday banner, so confirm the price at checkout.

    Martin AI costs $21 to $49 a month and prices like a consumer app; Sabi is $295 a month, and a founding member special running now brings that down significantly.

    What can Martin AI do, and what does it connect to?

    Martin covers the personal layer of work: its docs list calendar, inbox, Slack, reminders, to-dos, notes, search, email briefings, proactive drafts, email triage, wake-up calls, and Cc to Schedule. It can also place phone calls to you and to your contacts, which Sabi does not do.

    What its docs do not list is the sales and money stack most owners run on. Its integrations update covers Gmail, Slack, and Google Drive (beta); no CRM, Stripe, or QuickBooks appears anywhere we looked.

    Sabi connects to 200+ tools and acts in them, including the CRM and finance tools where leads and revenue live.

    IntegrationsSabi logo SabiMartin logo Martin

    Martin's documented integrations stop at email, calendar, Slack, and Drive; Sabi's 200+ connections include the CRM, payments, and accounting tools a business owner lives in.

    For calendar-only help, Martin's Cc to Schedule works like Howie; see how Sabi compares to Howie and Sabi's calendar features.

    What do Martin AI reviews say about reliability?

    Martin AI reviews are warm about the idea and mixed on follow-through. The App Store listing shows 4.3 out of 5 from 250 ratings, and a February 2025 review praises a "responsive dev team."

    The most detailed recent review, from March 2026 and titled "Fantastic App Potential but Many Many Problems and Lacking Support," is harder reading. The reviewer, who pays about $50 a month, writes: "I could not sign in even though my credentials were correct. I had to wait weeks for help," and "Martin couldn't call or text others."

    The company context matters too. Martin's YC profile now redirects to Letterbook, a customer support startup from the same founders, whose April 2026 launch post says "We grew our last product, Martin (an AI personal assistant), to 100,000 users."

    The iOS app last shipped an update (Telegram support) in January 2026, and the Martin blog's newest post is from April 2025.

    Martin AI holds a 4.3-star App Store rating, but its founders call it "our last product" in an April 2026 launch post for their next startup, Letterbook.

    What do you get with Sabi besides the software?

    With Sabi you get a team that stays in the loop; with Martin you get an app and a contact form. For a non-technical owner, that is the real split. Text-based AI assistants are getting common, so the layer around the assistant is what you are really choosing:

    • AI-human hybrid. The AI does the work, and real people stand behind her. A human touches every support ticket, and Sabi texts you when someone picks it up and again when it is fixed.
    • Unlimited credits. Sabi Pro is one of the only unlimited credit options: put her to work as much as you want, with no usage caps. Martin Basic limits proactive actions and runs 2 tasks at a time.
    • A private community. A network of business owners and entrepreneurs using AI in your industry.
    • High-level consulting. Pro members get weekly live calls with founders Stephen Diaz and Bruce van Zyl, real humans who know you by name.
    • Step-by-step courses. AI Certification 1.0 and 2.0, sold for $1,000+ on their own, plus AI trainings built for your industry. Pro members can bring their team to the live team trainings.

    One example: a pool service owner needed Sabi to work with a specialized software only pool companies use. There was no connector for it, so we built one for him. Most assistants leave you to figure integrations out alone.

    Our team has grown its own online businesses past $55M in sales (Inc. 5000 #148), and those playbooks are built into Sabi.

    Sabi is an AI-human hybrid that pairs the assistant with a human on every ticket, unlimited credits on Pro, weekly founder calls, a private community, courses, and custom-built connections; Martin pairs it with a contact form, a Discord, and docs.

    Who should pick Martin instead of Sabi?

    Pick Martin if you want a voice-first personal assistant and you like talking more than typing. It calls you with a wake-up briefing, texts and calls your contacts for you, speaks 13 more languages beyond English, and costs $21 to $49 a month with a 7-day free trial.

    Martin also wins on channels. You can reach it by phone, SMS, WhatsApp, email, Slack, and a native iOS app, and it added Telegram in January 2026. Sabi lives in text and iMessage, email, Slack, and web, and she does not place phone calls.

    Pick Sabi if the pain is the business: 300 unread emails, leads going cold, a P&L nobody has read. That needs CRM and payment connections and a team to call.

    For the rest of the field, see our full AI executive assistant comparison, or how Sabi compares to Poke, the other big personal assistant that lives in your texts.

    Martin fits individuals who want a cheap, voice-first Jarvis for daily life; Sabi fits business owners who want the admin done and humans behind it.

    How to choose a Martin AI alternative for your business: step by step

    Use the Backstop Test: for every task you would hand off, ask who fixes it when the assistant fails, and how fast. The assistant with the better backstop wins the tasks that cost you money.

    1. List the ten things you would hand an assistant this week. Include the wake-up call and the overdue invoice.
    2. Mark each one "annoying if it fails" or "expensive if it fails." A missed reminder is annoying. A missed follow-up on a $5,000 proposal is expensive.
    3. Check the tools behind the expensive ones. If they live in HubSpot, Stripe, or QuickBooks, the assistant must connect there.
    4. Find the backstop. Look for a named human, a response time, and a way to get on a call.
    5. Read the newest reviews, not the average. A 4.3 built over three years can hide a bad month.
    6. Run the Backstop Test after a week of real use. If the expensive column is longer, pick the assistant with the team behind her.

    Common mistakes owners make comparing Sabi and Martin AI

    • Picking on price alone. $21 a month is the right price for reminders. It is the wrong frame for the follow-up that closes a deal.
    • Assuming "connects to Gmail" means business-ready. Martin drafts and sends email well, but its docs list no CRM, Stripe, or QuickBooks. Check the tools where your money moves.
    • Trusting the star average. Martin's 4.3 includes 2024 praise; the detailed March 2026 review describes weeks-long sign-in and texting outages.
    • Skipping the roadmap question. Martin's founders launched Letterbook in April 2026 and call Martin "our last product." Ask any vendor who is building the product today.
    • Expecting a team tool. Sabi is single-user today, and Martin is a personal assistant. Neither sells shared seats.
