6 Best Micro (micro.so) Alternatives in 2026
Micro (micro.so) — the “everything app” from founder Brett Goldstein, which launched out of stealth in 2025 — puts email, CRM, meetings, tasks, docs, and an AI agent behind a single login. Its own FAQ describes it as “Superhuman meets Notion meets HubSpot,” and it’s aimed squarely at early-stage founders, investors, and small teams.
The bet is a good one, and the product is genuinely nice. But three things push people to look elsewhere:
- It’s Gmail-only. Micro’s docs walk you through connecting Gmail and Google Calendar. Outlook and Microsoft 365 aren’t listed. If your company runs on Microsoft, Micro is a non-starter.
- Everything is metered against a credit pool. Standard is $29/month for 6,000 credits; Pro is $59/month for 20,000. AI actions burn credits, and per Micro’s docs, integration calls do too. Unlimited credits only arrive at Enterprise, which is custom-priced.
- You have to move in. Micro replaces your inbox, your CRM, and your task manager at once. That’s the whole pitch — but it means migrating your stack before you find out whether the agent is any good, and the native integration list beyond that is short: seven MCP connectors (Granola, Slack, Notion, Linear, Stripe, Mem, Zapier), with everything else reached through Zapier, which is its own subscription.
Here are six Micro alternatives, starting with the one that solves all three.
1. Carly
Carly does the agent half of Micro without asking you to move in. It’s an AI agent platform that works on top of the email, calendar, and CRM you already use — you email it like a colleague and it does the work. Nothing to migrate, and no new inbox to learn.
Where Carly pulls ahead of Micro:
- Gmail and Outlook. Carly runs on Google Workspace and all of Microsoft 365. Micro is Gmail-only, which rules it out for most Microsoft-based teams.
- The metering shape is different. Carly’s Zapier-style workflow steps are free and unlimited — you’re not spending a credit every time a workflow touches an app. AI agents start at $35/month. With Micro, the AI and the integration calls both draw down the same monthly credit pool.
- 200+ native integrations, plus bring-your-own-key. Carly connects to 200+ tools natively, and anything else with a public API connects with your own key. Micro has seven native connectors and routes the rest through a separate Zapier plan.
- Agents can be client-facing. Each Carly agent gets its own name and email address, so it can reply to customers, vendors, and candidates directly. Micro’s agent works inside your workspace, for you.
Best for: Founders and small teams who want the agent and the automation without rebuilding their stack around it — especially anyone on Outlook.
2. Attio
AI-native CRM built for startups, with flexible data models, pipelines, and automations. Micro’s own marketing names Attio as a tool people switch from, which makes it the most direct like-for-like on the CRM side.
What makes it different from Micro: Attio is a real CRM rather than a super app — it syncs alongside your existing email instead of replacing it, and it supports both Gmail and Microsoft 365 Outlook (Microsoft-hosted accounts only; on-prem Exchange won’t sync). You keep your inbox; you just get a much better system of record. See Attio alternatives if you’re evaluating that layer specifically.
Best for: Startups that want a serious CRM and are happy keeping email where it is.
3. folk
Lightweight, Notion-feeling CRM aimed at relationship-driven teams — founders, agencies, recruiters, investors. Contacts, pipelines, and email sequences without enterprise overhead.
What makes it different from Micro: folk natively covers Gmail, Outlook, LinkedIn, and WhatsApp, so conversations land on the contact record whichever side of the Google/Microsoft divide you’re on. It’s narrower than Micro — no meeting recorder, no task manager, no general-purpose agent — but far less to adopt.
Best for: Solo founders and small teams whose CRM is really a relationship tracker.
4. Superhuman
The fast email client, now with AI drafting, triage, and follow-up reminders. If what you actually wanted from Micro was the inbox half, this is the sharpest version of it.
What makes it different from Micro: Superhuman supports Gmail and Outlook, and it stays an email client — no CRM, no pipelines, no credits ledger. You give up the unified workspace and get speed and keyboard-first polish in exchange.
Best for: People whose real complaint is email, not tool sprawl.
5. Lindy
AI executive assistant that triages your inbox, drafts replies in your voice, schedules meetings, and runs multi-step automations across a wide app list.
What makes it different from Micro: Lindy is agent-and-automation-first with no workspace to move into, which makes it the closer comparison to Micro’s agent than to its CRM. The catch is that Lindy drafts and waits for approval, so you’re still the one sending — if you want an agent that finishes and sends the work itself, Carly goes further. More options in Lindy alternatives.
Best for: People who want a proactive assistant and are happy reviewing its drafts.
6. HubSpot
The full CRM platform — contacts, deals, email marketing, ticketing, reporting — with a free tier and a long upgrade path.
What makes it different from Micro: HubSpot is what you graduate to, not what you start with. It’s heavier than Micro by a wide margin and nobody would call it an AI-first super app, but it supports every email provider, has an enormous app marketplace, and won’t run out of credits mid-month. Watch the tier jumps — see HubSpot alternatives before committing.
Best for: Teams that have outgrown founder tooling and need one CRM everyone can live in.

FAQ
Does Micro work with Outlook? No. Micro’s documentation covers connecting Gmail and Google Calendar, and doesn’t list Outlook or Microsoft 365. Carly, Attio, folk, Superhuman, and Lindy all support Outlook.
How much does Micro cost? Standard is $29/month with 6,000 AI credits, Pro is $59/month with 20,000 credits and unlimited connected email accounts, and Enterprise is custom-priced with unlimited credits. There’s a 14-day free trial.
What are Micro credits and what uses them? Credits are Micro’s usage currency for AI work — chat, automations, and skills all draw from the monthly pool, and per Micro’s docs, integration calls consume credits as well. That’s the number to model against if you plan to run automations continuously.
What’s the best Micro alternative if I don’t want to migrate my stack? Carly. It layers an agent and Zapier-style workflows on top of the inbox, calendar, and CRM you already have, so there’s no data migration and no second inbox.
Which Micro alternative is closest on CRM? Attio. Micro’s own site positions itself as the thing people switch to from Attio, so it’s the most direct comparison — with the difference that Attio leaves your email client alone and supports Microsoft 365.
Does any alternative give the AI its own email address? Carly does. Each agent gets its own name and address, so it can email clients, vendors, and candidates directly rather than only working inside your own workspace.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
