A different way to get work done
Martin alternatives.
Find your kind of assistant.
A personal assistant you reach by phone call, text, WhatsApp, email or Slack that runs your calendar, inbox, reminders and notes. If your priorities have changed, these 5 alternatives offer different ways forward.
What would you like to change?
You don’t need the assistant with the longest feature list. You need the one that fits the work you actually do.
Start with Noah AI
Everyday help in WhatsApp
An AI executive assistant you text over SMS, WhatsApp, iMessage, Slack or email to schedule meetings, send emails, set reminders and make phone calls for you. It is worth comparing with Martin when your priority is WhatsApp conversations, ongoing memory and reminders.
If you rely on mobile app or reusable instructions in Martin, check that gap before switching: Noah AI does not offer the same support.
The differences that matter
Keep Martin in the comparison. A different tool only helps if it changes something you care about.

A closer look at your alternatives
Here’s where each one makes sense—and what you give up in return.
01
Noah AI: everyday help in WhatsApp
An AI executive assistant you text over SMS, WhatsApp, iMessage, Slack or email to schedule meetings, send emails, set reminders and make phone calls for you. It is worth comparing with Martin when your priority is WhatsApp conversations, ongoing memory and reminders.
- Remembers you between conversations
- Reminds and nudges you
The trade-off. If you rely on mobile app or reusable instructions in Martin, check that gap before switching: Noah AI does not offer the same support.
Where you can use it
WhatsApp, iMessage, Slack, Email
02
The Librarian: voice and mobile use
A voice-first WhatsApp and SMS AI assistant for real estate agents that captures leads by voice, matches properties, drafts follow-ups, and runs their calendar and CRM tasks from the field. It is worth comparing with Martin when your priority is a native mobile app and voice input.
- Its own iPhone or Android app
- Voice messages
The trade-off. Check The Librarian’s plan limits and the exact apps your work depends on. A similar feature list does not guarantee that your existing Martin setup will transfer unchanged.
Where you can use it
Web / desktop, Mobile app, WhatsApp, Slack
03
Quin: help with ongoing context
Quin joins your meetings, drafts the follow-ups, and updates your CRM and connected tools automatically. It is worth comparing with Martin when your priority is memory between conversations and access to connected information.
- Remembers you between conversations
- Reads your existing files and apps
The trade-off. If you rely on whatsApp in Martin, check that gap before switching: Quin does not offer the same support.
Where you can use it
Web / desktop, Mobile app, Slack, Email
04
Junior: recurring work across apps
An AI employee that joins your Slack or Microsoft Teams and email, connects to your tools, and runs recurring work behind approval gates. It is worth comparing with Martin when your priority is scheduled or triggered tasks and connected-app actions.
- Runs on a schedule or a trigger
- Ready-made app integrations
The trade-off. If you rely on whatsApp or SMS in Martin, check that gap before switching: Junior does not offer the same support.
Where you can use it
Web / desktop, Slack, Email
05
Manus: cloud-based project work
A general-purpose AI agent with its own persistent cloud computer that plans and finishes multi-step work — research, slides, sites, data analysis — and reports back through Telegram, WhatsApp Business, Slack, LINE or email. Consider it if you want cloud computer and web browsing beyond your current Martin setup.
- Gives it a cloud computer of its own
- Browses the web for you
- Creates and edits documents
The trade-off. If you rely on SMS in Martin, check that gap before switching: Manus does not offer the same support.
Where you can use it
Web / desktop, Mobile app, Telegram, Slack, Email
You might be better off keeping Martin.
Someone reachable by phone, SMS, WhatsApp, email or Slack who wants their calendar, inbox and reminders run hands-free. If Martin already fits your work, check the alternative against a real task before taking on a migration.
Take another look at MartinBefore you move, check three things
- Your files and ongoing work. Decide what needs to move and what can stay in Martin.
- Your recurring tasks. Recreate one important task before rebuilding every automation.
- The actual effort. Compare setup, review time and usage costs—not just the demo.
