Marcus AI is a shared AI employee that a whole team hands work to in its web app, Slack, or Microsoft Teams, billed from one credit pool, and Sabi is one business owner's AI executive assistant you text, at a flat monthly price. In Sabi vs Marcus, the deciding question is whether the bottleneck is your team's output or you. This comparison covers pricing, channels, security, and support as of September 2026.

A quick note on the name: this post is about Marcus from heymarcus.ai, made by Zavo LTD in London. It is not Goldman Sachs' Marcus savings bank.

What is the difference between Sabi and Marcus?

Marcus is an AI employee for companies; Sabi is an AI executive assistant for one owner. Marcus's site guide calls it "a coworker with its own computer" that searches your tools, does the work, and hands back finished reports, dashboards, websites, and analyses. Its home page says it "researches your company, team and website" and then suggests tasks and automations.

Sabi starts from the owner, not the org chart. You text her "chase the two quotes from Tuesday and move my 3pm," and she does both in your Gmail and calendar. We built her for owners who don't want to learn another AI tool: no workspace to set up, no workflow canvas, no prompt engineering.

Marcus AI is a team AI employee that produces dashboards, reports, and campaigns across departments; Sabi is a personal AI executive assistant that runs one owner's inbox, calendar, and follow-ups over text.

	Sabi	Marcus
Category	AI executive assistant	AI employee for teams
Main job	Runs your admin: inbox, calendar, follow-ups, reporting	Team deliverables: dashboards, PDF reports, websites, ad audits, invoicing
How you use it	Text (mostly iMessage), email, Slack, web	Web app, Slack, Microsoft Teams, WhatsApp, text, email
Who it is for	Owners doing $10K to $100K per month	Teams, from marketing and sales to finance, up to Enterprise
Integrations	200+ tools, read and write	3,000+ tools, and it builds its own for any tool with an API
Company	Inovo Studios, United States	Zavo LTD, London, incorporated December 2022 (Companies House)

How much does Marcus AI cost compared to Sabi?

Marcus starts free and its Pro plan starts at $25 a month for 5,000 shared credits, with packs up to $10,000 a month; Sabi is $295 a month flat with no meter, and a founding member special running now brings that down significantly. Marcus's pricing page is per workspace, not per seat: "Your monthly pool, shared by the whole workspace."

Pricing	Sabi	Marcus
Retail price	$295/mo, month to month; currently running a founding member special that brings this down significantly	Pro from $25/mo (5,000 credits); $100/mo (20,000) is its "Popular" pack
Founding offer	Founding member special open now: significant savings for early users	None listed; unused credits roll over
How you pay	One flat price, one owner	Shared credits for the whole workspace, no seat fees
Top of the range	$295/mo; currently running a founding member special that brings this down significantly	$10,000/mo (2M credits), then Enterprise with a monthly minimum
Free start	Free starter credits, no card	Free plan, no card: 1 seat, 5 integrations, 5-minute tasks, 1 automation
Usage limits	Unlimited credits on Pro, no usage caps	Shared credit pool; unused credits roll over
Human support	A human touches every ticket, and Sabi texts you when it is picked up and when it is fixed	Live chat and email (one business day); a named contact on Enterprise

Marcus's pricing FAQ sizes a task: a quick task 50 to 150 credits, a multi-step workflow 250 to 750, a full project 1,000 to 2,500. At the $25 plan's rate of $5 per 1,000 credits, that is $0.25 to $12.50 per job, drawn from one pool every teammate and every automation shares.

Both cost a fraction of a US executive assistant at $84K to $144K a year plus benefits. Marcus's numbers come from its pricing page as of September 2026.

Marcus AI pricing runs from a free plan to $10,000 a month in shared credits; Sabi is $295 a month flat, and a founding member special running now brings that down significantly.

Is Marcus built for a team or for one owner?

Marcus is built for a team; Sabi is built for one owner. Marcus's Pro plan lists unlimited team members, and its security page describes role-based access "for teams of any size."

The customer stories on its home page are companies: a Sheraton hotel with 35 employees using it daily, a healthcare firm with 85.

Sabi has no seats to manage. She is "just you for now," and her memory is built around one person: your clients, your tone, your calendar habits. If you're weighing a similar team tool, see how Sabi compares to Viktor, which also bills a shared workspace in credits.

Team vs owner	Sabi	Marcus
Seats	Single-user	Unlimited on Pro; 1 seat on Free
Whose context	One owner's memory	Company-wide: channels it's invited to, team, website
Setup	About 60 seconds	Web app sign-up, then connect tools; Slack and Teams optional
Typical ask	"Reply to Dana and book Thursday"	"Build a live dashboard for the sales team"
Security paperwork	SOC 2 Type 2 program underway, no report yet	SOC 2 Type II, ISO 27001, ISO 42001
Approvals	Gate applies once you set an approval rule	Irreversible actions pause for approval by default

Marcus AI suits a company that wants one AI employee shared across departments with audit logs and certifications; Sabi suits an owner who wants a private assistant that knows only them.

What do you get with Sabi besides the software?

Sabi comes with people. Text-based AI assistants are getting common, so the layer around the software is where Sabi and Marcus split:

An 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's 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. Marcus draws every task from a shared credit pool.
High-level consulting. Pro members get weekly live calls with founders Stephen Diaz and Bruce van Zyl, real humans who know you by name.
A private community of business owners and entrepreneurs using AI in your industry.
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 invite their team to the live team trainings.
The 1st AI Hire Challenge, included when you try Sabi free: a 4-day live training where we give away for free what most AI gurus charge four to five figures for.

Marcus is self-serve on most plans, with live chat, email support, and a named contact on Enterprise; its partner page leaves training and rollout to agencies that charge implementation fees.

Beyond the software	Sabi	Marcus
Human help	AI-human hybrid: a human touches every ticket, with a text when it is picked up and when it is fixed	Live chat and email, reply within one business day
Onboarding	Sabi learns from your texts and memory	Marcus researches your company and suggests tasks
Live consulting	Weekly live calls with founders Stephen Diaz and Bruce van Zyl for Pro members	Not stated; a named contact on Enterprise
Community	Private network of owners using AI in your industry	Not stated
Courses and training	AI Certification 1.0 and 2.0, industry AI trainings, the 1st AI Hire Challenge free when you try Sabi	Training via partner agencies
Usage limits	Unlimited credits on Pro	Shared credits; every task and automation draws from the pool
Custom connections	White-glove: our team builds niche connections for you	The agent builds its own integration if the tool has an API
Built-in playbooks	From a team with $55M+ in online sales (Inc. 5000 #148)	A use-case library of 16 task types
Memory in other AI tools	Sabi Brain (MCP) into Claude, ChatGPT, Cursor, rolling out	Not listed on its site

One example from our own queue: a pool service owner needed Sabi to work with a specialized software only pool companies use. We built that connection for him. Marcus can write its own connector when a public API exists; many niche trade tools don't have one, and that is where a human team earns its keep.

Marcus AI pairs a capable team AI with self-serve setup and paid partner agencies; Sabi is an AI-human hybrid with unlimited credits, weekly founder calls, a private community, and courses built in.

Who should pick Marcus instead of Sabi?

Pick Marcus if a team, not one owner, needs an AI employee that ships finished deliverables: live dashboards, ad-spend audits, PDF reports, websites. Marcus reaches 3,000+ tools, shares one credit pool with no seat fees, and already holds the SOC 2 Type II and ISO 27001 certifications procurement asks for.

Sabi does none of the website or dashboard work and has no team seats today.

Marcus also has the lower entry price: a free plan and a $25 Pro tier.

Pick Sabi if you are the bottleneck. If the pain is your inbox, your follow-ups, and your calendar, and you'd rather text than learn a workspace tool, Sabi is the better Marcus AI alternative, at one flat price. For other team-style options, read our breakdown of Sabi vs Lindy or how Sabi compares to Skydive.

Marcus AI wins for teams that need cross-department deliverables and certified security; Sabi wins for one owner who wants admin handled over text at a flat price.

How to choose between a team AI employee and a personal assistant: step by step

Use the Bottleneck Test: name the one thing that slows the business down most this month. If it's the team's output, hire a team AI employee; if it's you, hire an assistant that works for you.

Write down the three jobs you'd hand off first. "Weekly ad report for the marketing team" is team output. "Answer the 40 emails I've ignored" is you.
Count who would ask it for work. One name means the Bottleneck Test points to Sabi. Five names point to Marcus.
Price a month of tasks. Take Marcus's ranges (50 to 2,500 credits a job) at $5 per 1,000 and compare the total to a flat $295.
Count the automations. Every scheduled run on Marcus spends credits; on Sabi, recurring tasks sit inside the flat price.
Ask what procurement needs. If a client or IT team requires a SOC 2 Type II report today, Marcus has one and Sabi doesn't yet.
Try both on real work. Marcus's Free plan and Sabi's free starter credits both skip the card.

Common mistakes owners make comparing Sabi and Marcus

Comparing $25 to $295 as if both were flat. Marcus's $25 buys 5,000 shared credits, roughly 33 to 100 quick tasks. Sabi's $295 has no meter. Price your month, not the entry tier.
Judging Marcus by the Free plan. Free caps each task at five minutes and one automation. Real team use starts on Pro.
Buying a team tool for a team of one. Unlimited seats and role-based permissions are wasted on a solo owner who mainly needs email and calendar handled.
Trusting every Marcus AI review on social media. Marcus runs a creator programme that pays up to $10,000 per post based on views. Look for disclosed sponsorships.
Expecting Sabi to build dashboards or websites. She runs your admin. If you need a live sales dashboard for 20 people, Marcus does that and Sabi doesn't.

We've watched owners stall for weeks on capable tools because nobody showed them where the ROI was. For the whole field, see our full AI executive assistant comparison.
