ABOUT OIAIR
What is OiAir?
OiAir is a marketplace for children’s activities in Brazil: sports, arts, music, science, languages, and other opportunities to grow. Our goal is to bring all organizations and their activities together in one place so families can find the right option easily.


Organizations in one place
We find organizations through public sources, collect and check information, translate it, and put it into a clear, consistent format. Families can then see and compare activities in one catalog. We are expanding it across Brazil.
Organizations describe their groups
An organization describes its activities and groups: which ages they suit, when they meet, what they cost, and whether a free trial is available. We publish confirmed details, helping those groups stand out among relevant options. Families see the terms upfront and can send an inquiry about a specific group.
Joining is simple: just speak
An organization opens a WhatsApp chat. Hermes, our AI agent, asks about its activities and groups. A representative can describe them by voice in about a minute, or answer by text. Hermes transcribes the answers and fills in a listing for the organization to review. Listing is completely free for the organization.
An easy search for families
In a simple interface, families choose a convenient location, their child’s age, weekdays or weekends, and see options on the map. The site is also available in Russian, English, and Spanish. Even without speaking Portuguese, they can write a question in their own language: OiAir helps prepare a Portuguese message for the organization.
Preparing access through AI assistants
We are preparing connections between the OiAir catalog and AI assistants through API, MCP, and WebMCP. A family will be able to ask a connected assistant to find an activity by age, location, and time, then send an inquiry to the organization in the same chat. As more organizations describe their groups, families have more options. A complete listing helps surface a suitable class and gives the organization another way to receive inquiries from new families.
AI agents with specific jobs
AI agents help us find organizations in public sources, check information, translate it, ask questions, and talk to representatives. Each handles a specific part of the work. Voice answers become structured information that families can search.
Families and organizations deal directly
OiAir helps families find an activity and forward an inquiry. The family arranges the details and payment directly with the organization. We do not take payment for classes, build a family purchase history, or sell personal data. We keep the records needed to deliver and track inquiries, along with limited catalog usage statistics.
Why it is free
We want to make life simpler for families, save time searching, and give children more opportunities to learn, play sports, and grow. AI agents handle repetitive work such as collecting, checking, translating, and organizing information. This lowers the cost of maintaining the catalog. That is why OiAir is free for families and organizations.
Free for families and organizationsAn easier way for organizations to receive inquiries
Once published, an organization gets a link to its activities. It can place the link on its website, social profiles, WhatsApp, and map listing. Wherever a family finds the organization, it opens the same simple form, chooses a group, and sends an inquiry. The organization can receive inquiries more easily, and families can find the activity they want.
