Different Jobs, Different Tools
Manus is a task runner — give it a job like “build me a website” or “research this market” and it works autonomously in a cloud browser. It’s impressive for one-off projects.
Slime is a personal assistant — it knows your life and helps you run it, every day. They solve fundamentally different problems.
You talk. Slime remembers.
Say “remind me about Sarah’s birthday” and Slime knows who Sarah is. Say “schedule the usual meeting” and it knows the time, length, and attendees. That’s persistent memory — it gets smarter every day because it remembers you. Manus starts fresh every task. It doesn’t know who you are.
Your notes become something
Talk through a half-baked idea. Slime transcribes on-device, then shapes it into action items, a journal entry, or a step-by-step plan — 7 writing styles, switch anytime. When an idea is ready, promote it to a calendar event, a doc, or a reminder. Manus can’t capture thoughts — it runs tasks you’ve already figured out.
Your day, managed by voice
Morning briefings combine your calendar, email, reminders, and weather into one 30-second update. Triage your inbox by voice in 5 minutes while walking. Create events, reschedule meetings, draft replies — all by speaking.
Costs less, no surprises
Manus charges $19–199/month with credits that expire monthly and don’t roll over. Each task uses credits unpredictably. Slime uses simple pay-per-use credits — no expiration, no subscription tiers, no surprise bills.
Your data stays yours
Manus was acquired by Meta in 2026 — your tasks run through Meta’s infrastructure. Slime is an independent company. Speech recognition runs on-device. Every connector is first-party and audited.
Manus is better if…
You need an AI to do complex computer work — build websites, create presentations, run deep research, automate browser tasks. If you have well-defined projects that need autonomous execution, Manus is built for that.
Slime is better if…
You want an AI that knows your life and helps you manage it — by voice, every day. Notes that become action. A calendar that manages itself. An inbox you handle while walking. An assistant that remembers everything and costs a fraction of Manus.
