Outside of ChatGPT: Reka vs. Manus
When to use Reka and Manus
Everyone’s talking about agentic AI right now.
And if you’ve heard of Reka, you might’ve seen people comparing it to Manus — claiming they both belong in the same “autonomous AI” category.
After testing both, I can tell you:
👉 They’re not playing the same game.
Let’s break it down.
Reka = A smarter, faster assistant
Reka is a high-performing multimodal LLM — a competitor to ChatGPT and Claude.
It’s designed for:
Conversational Q&A
Quick content creation
Brainstorming and editing
Understanding text, images, and even video
It’s fast. It’s free. And it’s very good at saving time across the types of marketing and strategy work we all do daily.
If you need to:
Spin up a draft
Review a PDF
Rewrite something for a client
Brainstorm social content
Summarize a webinar or meeting notes
Reka is a fantastic option — especially if you're looking to expand your AI toolkit beyond ChatGPT.
But don’t confuse it with agentic AI.
Manus = A digital team member
Manus isn’t here to co-write your emails.
It’s here to run your systems.
You give it a directive like:
“Build and launch a 3-email nurture campaign in ConvertKit, tag leads in my CRM, and create a content brief for the follow-up blog post.”
And it just... does it.
It doesn’t ask for 3 more prompts. It doesn’t spit out a to-do list.
It breaks down the task, chooses the tools, and executes.
That’s what agentic AI really means — and that’s what separates Manus from tools like Reka or ChatGPT.
TL;DR — What They’re Built For
If you’re wondering which tool to use, here’s the breakdown:
✅ Use Reka if you want to...
Write faster
Generate content or brainstorm ideas
Answer complex questions
Analyze documents, images, or video
Get quick insights and move faster
✅ Use Manus if you want to...
Run multi-step campaigns or workflows
Automate tasks across tools and platforms
Build systems (like CRMs, funnels, or follow-up flows)
Delegate entire projects, not just tasks
Work like a team of 5 with just you and AI
💡 Bottom line:
Reka helps you think and write faster.
Manus helps you get things done without lifting a finger.
Final thought
A lot of people are lumping every AI tool into the same bucket.
But tools like Reka and Manus are solving very different problems.
Reka is about speed, writing, insight. A smart assistant.
Manus is about scale, execution, and system-building. A digital team member.
If you’re a marketer, strategist, or solo founder trying to build smarter and move faster, both are worth your time — but use them for what they’re good at.
