The best AI for getting things done depends on the kind of doing. Lindy wins for building repeatable automations; ChatGPT's agent mode leads on autonomous web and computer tasks; Martin is a strong chief of staff for your work stack. Memonion is the best for getting personal, everyday things done from your chat — with memory of your life, proactive follow-up, and a human-in-the-loop check before anything irreversible.
For years "AI can do that" really meant "AI can tell you how to do that." The interesting shift in 2026 is the move from advice to action — and the tools split sharply by what kind of doing they're built for. We build Memonion, so we're biased, but this roundup describes each competitor by its real strength and is clear about where it beats us.

The gap that matters: advice vs. action
Every tool here can talk. What separates them is whether they close the last mile — taking the plan and executing it: doing the research, writing the draft, setting up the booking, chasing the reply. The second thing that separates them is where they stop. Doing everything is easy to promise and dangerous in practice; the tools worth trusting stop before your money, your login, and your irreversible calls.
"Here's how you could" is a search result. "It's done, just confirm this one step" is an assistant.
The contenders
Lindy — best for building repeatable automations
Lindy lets you assemble agents that run specific, repeatable cross-app workflows — the recurring machinery of your work, automated once and left to run. For a power user who knows exactly what they want automated and is happy to build it, that control is the strongest option here. The cost is setup: it's a builder, so the doing starts after you've wired it up.
ChatGPT agent mode — best for autonomous web and computer tasks
ChatGPT's agent capabilities can browse, click, and carry out tasks across the web on your behalf, backed by frontier reasoning. For open-ended "go figure this out and do it online" jobs, it's genuinely impressive and often leads the pack. It's oriented around task sessions you launch rather than a companion that remembers your life and reaches back to you over time.
Martin — best chief of staff for your work
Martin executes across your work stack — email, calendar, messages — and pushes proactive briefings, with a strong voice-first feel. For getting work things done with a chief-of-staff style, it's excellent. It's tuned to your professional life more than your whole life, and it rewards connecting your tools.
Manus — best for open-ended autonomous projects
Manus made its name running longer, autonomous multi-step projects — handing it a goal and letting it work through the steps. For ambitious, self-directed tasks, that autonomy is a real strength. It's more of a launch-a-project agent than an always-there companion living in your messages.
Memonion — best for getting life done from your chat
Memonion does the everyday doing that actually clogs your week — research, drafts, plans, reminders, inbox and calendar help — from Telegram, WhatsApp, or WeChat, with no setup and full memory of your life. Crucially, it follows up proactively and stops at the right line: anything touching your login, money, or a final decision is prepped and handed to you. It's not the most autonomous agent on the list; it's the one that gets your real life moving without you leaving your chat. Free to start; Pro is $19/mo.
The honest bottom line
Want to build automations you control? Lindy. Want an agent that roams the web autonomously? ChatGPT agent mode. Want a chief of staff for work, or an autonomous project runner? Martin or Manus. And if you want an AI that quietly gets your life done — remembering your context, following up, and stopping before anything irreversible — that's Memonion.
