Almanac AI (usealmanac.com) is a $20-a-month Mac workspace that turns your work into a self-updating wiki and task list, and Sabi is an AI executive assistant you text who does the admin. In Sabi vs Almanac, the question is whether you want a better desk or fewer tasks. Price, setup, and support as of September 2026.

What is the difference between Sabi and Almanac AI?

Almanac AI is a personal AI workspace for people who work at a Mac; Sabi is an assistant for business owners who run the day from a phone. Almanac's home page calls itself "a personal workspace for working with AI" that keeps "your tasks, projects, conversations, and knowledge" organised, with a wiki you can explore and correct.

It is not the older Almanac wiki tool at almanac.io. This Almanac is a Y Combinator Summer 2026 company, founded in 2025 by a team of three in San Francisco, per its YC profile.

Sabi works from the other end. You text her "chase the Henderson quote and move my Thursday call," and she does both in your Gmail and calendar. We built her for owners who don't want to learn another AI tool: no app to install, no workspace to organise, no prompts to write.

Almanac AI organises your work into a wiki and task list on your Mac; Sabi is an AI executive assistant that takes the task off your plate from a text.

	Sabi	Almanac
Category	AI executive assistant	Personal AI workspace with a self-updating wiki
Main job	Does your admin: inbox, calendar, follow-ups, reporting	Organises tasks, projects, and knowledge; prepares drafts
How you use it	Text (mostly iMessage), email, Slack, web	Mac desktop app, plus iMessage once connected
Who it is for	Owners doing $10K to $100K per month	People who work at a Mac with AI; "built for teams" next
Company	Inovo Studios, United States	Reverie Project, Inc. (dba Almanac), San Francisco, YC S26

How much do Sabi and Almanac AI cost?

Almanac AI pricing is one plan, $20 a month, but it also needs your own ChatGPT subscription; Sabi is $295 a month flat with nothing else to buy, and a founding member special running now brings that down significantly. Almanac's pricing page says: "Bring your ChatGPT subscription. Almanac runs on your Codex usage limits; the subscription is paid separately."

Pricing	Sabi	Almanac
Retail price	$295/mo, month to month; currently running a founding member special that brings this down significantly	$20/mo (Almanac Pro, the only plan)
Founding offer	Founding member special open now: significant savings for early users	None listed
AI usage	Unlimited credits on Pro, AI included: no usage caps	Runs on your ChatGPT subscription's Codex limits, billed separately
Free start	Free starter credits, no card	7-day trial, card required, renews at $20/mo
Refunds	Month to month, cancel anytime	Fees non-refundable except where law requires, per its terms
Human support	AI-human hybrid: a human touches every ticket; weekly live founder calls for Pro members	A Contact link that opens an email to a founder

Both cost a fraction of a US executive assistant at $84K to $144K a year. Almanac's numbers are from its pricing page, September 2026.

Almanac AI costs $20 a month plus a ChatGPT subscription you already pay for; Sabi costs $295 a month with the AI included; a founding member special running now brings Sabi's price down significantly.

Does Almanac AI do the work, or prepare it for you?

Almanac prepares by default and finishes when you tell it to; Sabi is built to finish the task. Almanac's FAQ says its "default instructions are to prepare drafts and leave consequential final steps to you, unless you have asked it to carry them out."

Almanac can go further. Its YC launch post says it "works with its own browser and terminal, signed into the accounts you connect," files GitHub issues, fixes small production bugs, and "pings you or hands you the live browser" at a login or payment.

Doing the work	Sabi	Almanac
Default	Does the task you text her	Prepares drafts; final steps are yours unless you ask
Inbox and calendar	Triages, drafts, sends; books and moves in Gmail, Outlook, Google Calendar	Drafts replies in the thread; meeting briefs from email and calendar
Business tools	200+ connections: HubSpot, Salesforce, HighLevel, QuickBooks, Stripe	No count listed; connected accounts, MCP servers, and a managed browser
Engineering	Not her job	Terminal, GitHub issues, small fixes as pull requests
Automations	"Every Monday at 7 a.m., send last week's Stripe revenue"	"Automations are just sentences," no workflow builder
Memory	Learns you over time; Sabi Brain (MCP) carries it into Claude, ChatGPT, Cursor, rolling out	Source-backed wiki you can correct; Claude Code and Codex can read it

Almanac AI drafts and waits for your go by default, with a terminal for code; Sabi completes inbox, calendar, and follow-up tasks across 200+ business tools from a text.

Where do you use each one: at a desk or on your phone?

Almanac starts on a Mac; Sabi starts in your messages. Almanac's download page lists Apple Silicon, macOS 12 or later, version 0.24.1, and its FAQ says to "start with the Mac desktop app" and connect iMessage during setup to keep going from your phone.

Sabi needs no computer at all; you can also reach her by email, Slack, or the web.

Setup	Sabi	Almanac
What you need	A phone	An Apple Silicon Mac and a ChatGPT subscription
Setup time	About 60 seconds	Download the DMG, move to Applications, sign in, connect ChatGPT
Laptop closed	Nothing to keep open	Cloud work continues; local files and apps need the Mac on
Windows or no computer	Works	Mac only on its download page

If you run your business between job sites and calls, the device settles most of this. For a team-agent contrast, see Sabi vs Lindy.

Almanac AI requires an Apple Silicon Mac and your own ChatGPT plan to start; Sabi needs only a phone and about 60 seconds.

What do you get with Sabi besides the software?

Sabi comes with people: a human on every ticket, unlimited credits on Pro, weekly founder calls, a private community, courses, and connections we build for you. Almanac's site lists a founder's email as its contact and no community, courses, or onboarding calls.

Beyond the software	Sabi	Almanac
Human help	AI-human hybrid: a human touches every ticket and texts you when it's picked up and fixed	Email to a founder via the Contact link
Usage limits	Unlimited credits on Pro, no usage caps	Runs on your ChatGPT plan's Codex limits
Live consulting	Weekly live calls with founders Stephen Diaz and Bruce van Zyl for Pro members	Not listed
Community	Private network of business owners using AI in your industry	Not listed
Courses and training	AI Certification 1.0 and 2.0, industry AI trainings, live team trainings for Pro members; the 1st AI Hire Challenge when you try Sabi free	Not listed beyond the FAQ
Custom connections	White-glove: we build niche connections for you	You configure custom integrations and MCP servers yourself, per its terms
Built-in playbooks	From a team with $55M+ in online sales (Inc. 5000 #148)	Not listed
Memory in other AI tools	Sabi Brain (MCP) into Claude, ChatGPT, Cursor, rolling out	Wiki readable by Claude Code and Codex, per its launch post

Text-based AI assistants are getting common. The layer around Sabi is what sets her apart:

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. Almanac runs on your ChatGPT plan's Codex limits.
A private community 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 for your industry; Pro members can bring their team to live team trainings. Trying Sabi free includes the 1st AI Hire Challenge, a 4-day live training where we give away what most AI gurus charge four to five figures for.

One example from our own queue: a pool service owner needed Sabi to work with Skimmer, a specialized software pool companies use. We built that connection for him. Almanac's terms put that job on you: if you configure a custom integration, "you are responsible for" its "security, configuration, permissions, and data."

Your data is never sold or used to train AI, you can download a copy any time, and you can import your ChatGPT memories into Sabi's private brain.

Almanac is a self-serve app from a three-person team; Sabi is an AI-human hybrid with unlimited credits, founder calls, a private community, and courses.

Who should pick Almanac instead of Sabi?

Pick Almanac if you already pay for ChatGPT, work all day on a Mac, and want your projects organised into a wiki you can correct. At $20 a month it is a cheap way to get an AI that remembers your work, and its terminal handles technical jobs Sabi doesn't touch, like filing GitHub issues.

Its direction also points at teams. Almanac's YC profile says it "starts with individuals, but it's built for teams," and its launch post says teammates' Almanacs share one wiki. Sabi is single-user today: "just you for now."

Pick Sabi if you are the bottleneck and the pain is volume: 300 unread emails, leads nobody chased, a calendar you manage by hand. If you want context carried into other AI tools, see how Sabi compares to MyGentic and our OpenClaw alternative breakdown.

Almanac AI wins for Mac-based knowledge workers who already pay for ChatGPT; Sabi wins for business owners who want admin handled over text with a team behind her.

How to choose between an AI workspace and an AI assistant: step by step

Use the Desk-or-Pocket Test: if most of your work happens at a Mac where you would open a workspace and review drafts, pick a desk tool; if it happens on your phone between everything else, pick an assistant you text.

Track a normal Tuesday. Six hours at a Mac points to Almanac; six hours on the road or on calls points to Sabi.
List the five tasks you'd hand off first. Mark each "organise" or "finish." A wiki and task list help with organising; an assistant helps with finishing.
Add up the real bill. Almanac is $20 plus the ChatGPT plan it runs on; Sabi is one price with the AI included.
Check your devices. No Apple Silicon Mac means Almanac isn't an option today.
Ask who helps when you're stuck. A founder's inbox, or a human on every ticket plus weekly founder calls for Pro members.
Run one real week. Almanac gives 7 days with a card; Sabi gives free starter credits with no card.

Common mistakes owners make comparing Sabi and Almanac

Comparing $20 to $295 as if both were complete. Almanac's $20 runs on a ChatGPT plan you pay for separately. Price the whole setup.
Buying a better desk when the problem is the pile. We've watched owners organise a workspace for a week and still have the same follow-ups undone.
Assuming "drafts ready" means done. Almanac's default is to leave consequential final steps to you. That is safe, and it also means you still press send.
Mixing up the Almanacs. Almanac AI at usealmanac.com is not the Almanac wiki tool at almanac.io. Check the domain before you read a review.
Expecting Sabi to write code. She runs your admin. If you want an agent in a terminal fixing bugs, Almanac does that and Sabi doesn't.
