Tomo vs Martin: Which AI Should You Text in 2026?
Both live in your texts, but they do opposite jobs. Tomo is a text-based AI accountability coach that learns your goals, checks in on you, and nudges you to stay consistent with habits and personal projects. Martin is a personal AI assistant you reach by text, call, WhatsApp, email, or Slack that actually runs your calendar, inbox, and to-do list. If you mainly need someone to keep you on track, Tomo. If you want someone to do your admin work, Martin.
The One-Sentence Answer
Use Tomo if you want a coach that changes your behavior; use Martin if you want an assistant that clears your busywork.

When to Use Tomo
- You want daily check-ins that keep you honest about habits and goals
- You’re a student, creator, or freelancer who needs a nudge, not a chief of staff
- You like a low-friction AI that lives in your text thread and follows up naturally
- Your problem is follow-through, not a full inbox
Tomo grew to more than 10,000 paying users largely by word of mouth, and it can connect to your calendar, email, Notion, and Google Drive. Reviewers note its memory is still imperfect and replies can get repetitive, and it is not built for large business workflows. Think of Tomo as a pocket coach that texts you to keep you moving.
When to Use Martin
- You want your calendar scheduled and rescheduled without touching it
- You need email triaged, drafted, and replied to on your behalf
- You want an assistant reachable by phone call, WhatsApp, or Slack, not just an app
- Your problem is too much admin, and you’d hand off tasks if you could
Martin’s Basic plan lets you assign a couple of tasks at a time with limited proactive actions; the Pro plan adds unlimited proactive actions, premium AI models, email pre-drafting, and longer-term memory of your preferences. It works with both Gmail and Outlook and offers a seven-day free trial.
The Accountability vs Admin Line That Decides It
The real split is what you want the AI to change. Tomo works on you. It remembers your goals, sends proactive check-ins, and keeps you consistent, which is why users message it most days of the month. It can hook into your calendar and email, but that is a side feature, not the point. Martin works on your accounts. It connects to Gmail or Outlook, manages your calendar, drafts and sends email, sets reminders, and even makes calls for you across multiple channels. Tomo is closer to a habit and life coach; Martin is closer to an executive assistant. Pick by whether your bottleneck is motivation or minutes.
Rule of thumb: need to stay accountable to your goals → Tomo; need someone to run your calendar and inbox → Martin.
If the real goal is getting the work done rather than managing either app, neither tool goes as far as a full assistant. Carly is an AI executive assistant you email or text — it schedules meetings, handles email, and runs tasks on your behalf. It also automates multi-step workflows across 200+ integrations.

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."
