What is Multimango? The AI rating tool behind Outlier's Aether project
Overview · 1 week ago
Multimango is not a company you apply to. It is a web tool where contractors rate and annotate AI outputs, and its terms say you are engaged and paid by a separate administrator: in practice the vendor you already work through, such as Outlier, TELUS Digital, RWS, Mercor or CrowdGen. Here is what its terms say, how people get access, and what changed in 2026.
The short answer
Multimango is a web tool, not an employer. Contractors open it to rate and annotate AI model outputs, but nobody signs up with Multimango directly. Its terms of use say participants are engaged and paid by a separate "Research Administrator", and in practice that is the vendor you already work through.
Worker reports name five or six vendors sending people into the same Multimango tasks: Outlier, where the project is called Aether, TELUS Digital, RWS, Mercor, CrowdGen by Appen and Workada. That is why so many people search for the name: they meet it inside a vendor's dashboard, with no explanation of what it is.
What Multimango's own terms say
Multimango's terms of use, checked on 3 October 2026, describe it as a platform for research projects that "rate the quality and relevancy of outputs generated from various AI models". The privacy notice, dated 9 September 2025, calls it "an open resource" for the same kind of research.
The key points for a worker:
- Someone else pays you. The terms describe a Research Administrator that may pass your details to Multimango and pays you under its own agreement with you. Taxes on that pay are your responsibility, and either party may withhold tax where it is legally required to.
- You are not an employee. The terms say you are free to work for anyone else.
- Location limits. You must have the right to work in the country you are in. The terms exclude citizens and permanent residents of countries under comprehensive US trade sanctions (they name Cuba, North Korea, Iran, Sudan and Syria), and say some research excludes residents of Illinois and Texas.
- A lot of personal data. Beyond name, contact details and date of birth, the terms allow collection of your Facebook or Instagram ID, race, ethnicity, household income, education level, country of origin and native language, along with your responses and recordings. Our privacy checks before AI training work explain what to weigh before agreeing to that.
The terms and privacy notice refer to the operator only as "the Responsible Data Controller". The company name sits behind a "Show details" button on a separate legal page, not in the documents themselves. Privacy requests go to dataprivacy@multimango.com.
What the work looks like
Workers describe mostly multimodal judgement tasks: choosing the better AI edit of a photo, judging images generated from sketches, drawing boxes on screenshots, and rating answers in conversations that mix text, images and video. Multimango's own interface also includes an audio annotation task: labelling who is speaking, correcting a transcript and marking sound events.
Workers report that the generalist tasks needed no specialist degree, which made the project one of the easier ones to get onto in 2025. Our guide to video, image and design AI training jobs covers this kind of work and what it pays across platforms.
How you get access
There is no public sign-up. Your vendor places you on the project, and you keep seeing your status, hours and pay on the vendor's side; you sign in to Multimango only to do the tasks.
Pay is set by the vendor, not by Multimango. Workers report rates that vary widely by vendor and by country, so two people doing the same task can be paid very differently. Check the rate on your vendor's project page before you start, and see how much AI training jobs pay for typical ranges.
What changed in 2026
According to worker reports, the large generalist phase of Multimango work wound down between late 2025 and early 2026, and some workers say their onboarding documents listed that end date from the start. A smaller group is still working in Multimango on image and video evaluation, which on Outlier is the Aether project.
If you lost your Multimango tasks, the vendor account usually still exists. Our guide to being accepted but getting no tasks covers what to do next, and applying to several platforms at once explains why one project should never be your only source of work.
Is Multimango legit?
As a tool, yes: it is the place where established vendors send real, paid contractors, and it publishes full terms and a privacy notice. The thing to check is the invitation, not Multimango itself. A genuine invitation comes through a vendor you already have an account with. Nothing in Multimango's published terms involves paying a fee, and a message offering Multimango work from someone you have never contracted with should be treated as a likely scam. Our guide to spotting fake AI training jobs covers the warning signs.

Questions
- What is Multimango?
- Multimango is a web tool where contractors rate and annotate AI model outputs for research projects. It is not an employer: its terms say participants are engaged and paid by a separate Research Administrator, which in practice is a vendor such as Outlier, TELUS Digital, RWS, Mercor or CrowdGen.
- How do I sign up for Multimango?
- You cannot sign up directly. A vendor you already work for places you on a Multimango project, and you sign in to Multimango only to do the tasks. Your status, hours and pay stay on the vendor's side.
- Is Multimango legit?
- Yes, as a tool: established vendors send paid contractors into it, and it publishes full terms of use and a privacy notice. A genuine invitation comes through a vendor you already have an account with. Treat any Multimango offer from someone you have never contracted with, or any request for a fee, as a likely scam.
- How much does Multimango pay?
- Multimango does not set the pay. Your vendor does, and workers report rates that vary widely by vendor and by country. Check the rate on your vendor's project page before you start.
- Is Multimango the same as Outlier's Aether project?
- Aether is the name Outlier uses for its work inside Multimango, according to worker reports. Other vendors send their contractors into the same tool under their own project names.
- Is Multimango still hiring?
- Worker reports say the large generalist phase wound down between late 2025 and early 2026, and a smaller group still works on image and video evaluation. There is no open sign-up; new access depends on a vendor placing you on a project.
