TL;DR
Motion is the best pure auto-scheduler: give it tasks and deadlines and it will keep rebuilding your calendar around them. Sunsama is the best manual daily ritual: you plan your day by hand, deliberately, and shut down cleanly. Argus is the only one of the three that acts like an assistant rather than a planner — it reads your inbox, preps your meetings, builds the plan for you, and can literally call you with it.
If you want a tool you maintain, pick Motion or Sunsama. If you want something that takes work off your plate, pick Argus — and it starts at $9/mo, well under both.
At-a-glance
| Tool | Best for | Price | Scheduling | Voice | Proactive | |
|---|---|---|---|---|---|---|
| Argus | People who want an assistant, not another planner to maintain | From $9/mo | Plans your day, schedules tasks around meetings | Deep — triage, nudges, drafts, and recurring email routines | Two-way calling — call Argus, or Argus calls you | Yes — briefings and routines run on their own |
| Motion | Heavy task-jugglers who live in a calendar | ~$34/mo individual (annual) | Strongest — continuous auto-rescheduling engine | Limited — light email/calendar assistant features | No phone assistant | Partly — reschedules automatically, but you feed it tasks |
| Sunsama | People who want an intentional, manual daily ritual | ~$20/mo (annual) | Manual drag-and-drop timeboxing | Pull emails in as tasks; no autonomous handling | No phone assistant | No — the ritual is deliberately human-driven |

Argus
Argus is a proactive assistant rather than a planning surface. Connect Gmail and Google Calendar and within about five minutes it is running: a morning briefing that covers your schedule, weather, and the emails that actually need you; meeting prep before each call; a day plan that slots tasks around your real calendar; and an end-of-day recap that rolls unfinished work forward.
- Argus Calling — two-way phone conversations with your assistant, 60 minutes included monthly.
- Email routines — recurring, autonomous inbox triage, drafts, and follow-up nudges.
- Text and Slack — capture tasks or ask for a status from wherever you already are.
- Memory — Argus remembers your people, projects, and preferences between conversations.
- Price — from $9/mo, cancel anytime.
Weakness: Argus does not run a continuous auto-rescheduling engine the way Motion does. It plans your day and adjusts, but it will not obsessively re-timebox every task the moment a meeting moves.
Motion
Motion's core idea is that you should never decide when to do something. You add tasks with durations, deadlines, and priorities; Motion's scheduler drops them into open calendar slots and reshuffles automatically when meetings appear. For people with a large, deadline-driven task list, that engine is genuinely the best in the category.
- Strengths: aggressive auto-scheduling, project and team views, meeting booking pages.
- Limits: email handling is thin — it will not run your inbox for you; there is no phone assistant.
- Cost: among the priciest individual productivity subscriptions, roughly $34/mo annually.
- Overhead: the schedule is only as good as the task metadata you keep entering.
Pick Motion if your bottleneck is purely "when do I do all this?" and you are willing to maintain a well-groomed task database to feed it.
Sunsama
Sunsama is the anti-automation option, on purpose. Each morning it walks you through choosing what you will actually do today, pulling tasks in from Gmail, Asana, Jira, Notion, and Trello, then asks you to estimate time and timebox it by hand. At day's end it runs a shutdown review. It is calm, opinionated, and effective for people who like the ritual.
- Strengths: guided daily planning, excellent task aggregation, deliberate pace.
- Limits: nothing happens unless you sit down and do the ritual; no autonomous email work, no voice.
- Cost: around $20/mo annually.
Pick Sunsama if your problem is intention and overcommitment rather than volume, and you want a human ritual instead of an algorithm.
What only Argus does: Argus Calling
Neither Motion nor Sunsama has a phone assistant. Argus does, in both directions:
- Call Argus from your car and talk through your day, dictate tasks, or hear what is in your inbox — hands-free.
- Have Argus call you at a scheduled time to deliver your morning briefing out loud.
- 60 voice minutes included every month; top-ups are non-expiring.
This is the difference between a tool you have to open and an assistant that reaches you. A planner cannot help you at 7:40am on the freeway. A phone call can.
Email: routines vs. task import
This is the second big gap. Motion and Sunsama both let you turn an email into a task — a useful feature, but it still leaves you doing every bit of the email work itself. Argus treats the inbox as a job to be run:
- Recurring triage that separates what needs you from what does not.
- Drafted replies in your voice, waiting for a one-tap send.
- Follow-up detection — threads you sent that nobody answered come back to you.
- Briefings that summarize the inbox instead of just linking to it.
If email is where your day disappears, that difference matters far more than timeboxing precision. See the email features.
Which should you pick?
- You have too many tasks and not enough hours: Motion.
- You overcommit and want a calmer, intentional day: Sunsama.
- Your inbox and follow-ups are the real problem: Argus.
- You want briefings and hands-free access by phone: Argus — the only option here.
- You want the lowest monthly cost: Argus at $9/mo vs roughly $20 and $34.
- You want an assistant, not another app to maintain: Argus.

Frequently asked questions
What is the main difference between Argus, Motion, and Sunsama?
Motion is an auto-scheduling calendar, Sunsama is a guided manual daily planner, and Argus is a proactive assistant. Motion and Sunsama both assume you bring the tasks and manage the plan. Argus works the other way around: it reads your inbox and calendar, builds the plan, briefs you each morning by text or phone call, and follows up on what you did not finish.
Which one is best for email?
Argus. Motion and Sunsama treat email mostly as a source of tasks — you still open your inbox and do the work. Argus runs email routines: triaging what matters, surfacing messages that need a reply, drafting responses, and nudging you on threads that have gone quiet.
Can any of them make phone calls for me?
Only Argus. Argus Calling lets you call your assistant to talk through your day, dictate tasks, or hear your inbox summary hands-free, and Argus can call you at a set time with your briefing. Neither Motion nor Sunsama has a voice or phone assistant.
Is Motion worth it over Argus?
If your single biggest problem is fitting a long task list into a packed calendar, Motion's auto-scheduling engine is the most aggressive on the market. If your problem is broader — email piling up, meetings you show up to unprepared, follow-ups you forget — Argus covers more of the day at roughly a quarter of the price.
Is Sunsama better than Argus for focus?
Sunsama's plan-and-shutdown ritual is genuinely good if you enjoy sitting down each morning to build your day by hand. Argus is for people who would rather that plan already exist when they wake up. Some users run Sunsama for the ritual and Argus for the inbox and phone briefings.
How much do they cost?
Argus starts at $9/mo with cancel-anytime billing and includes 60 voice minutes a month. Sunsama is around $20/mo billed annually. Motion is around $34/mo per user billed annually for individuals. Check each vendor's pricing page for current numbers.
Can I use Argus alongside Motion or Sunsama?
Yes. Argus connects to Google Calendar and Gmail, so it can brief you and handle email and follow-ups while Motion or Sunsama owns your timeboxing. Most people eventually consolidate, but there is no conflict in running both.
