Short answer
Build a campus student resale marketplace by choosing who can join, deciding what items students may list and setting clear rules for direct meetups. Use AI to plan the screens and create the storefront. Tradly supports seller accounts, listings, messaging and checkout, while student eligibility checks may need a separate process.

Step 1 · Scope
Choose who can list and what can be sold
Start with one campus community and a short list of product categories such as textbooks, electronics and room essentials. Decide whether alumni or staff may join, what items are prohibited and how listings expire at term end. Keep the first version small enough for moderators to review reports and help new users.
Tradly: Tradly supports seller accounts and listings; your campus rules define eligibility, permitted items and listing duration.

Step 2 · Access
Design a practical student eligibility process
The source request asks for college-email-only sign-up, but email-domain verification is not listed in the feature catalog. Decide whether a person or a third-party identity service will check student eligibility. Explain what information is collected, who can see it and how a student can appeal a failed check.
Tradly: Tradly vendor onboarding includes sign-up and an approval flow; use a verified process for any student-only access requirement.

Step 3 · Meetups
Set safe handoff and communication rules
If students exchange items in person, recommend public campus locations and state that buyers and sellers arrange the handoff directly. Provide a process for reporting suspicious listings or missed meetups. Do not imply that the platform inspects items or guarantees a face-to-face transaction.
Tradly: Tradly buyer-seller chat lets participants ask questions and coordinate details inside the marketplace.

Step 4 · Build
Prompt AI with the student journey
Give the AI builder examples of a textbook listing and a buyer looking for a lamp. Ask it to create a simple home page, category browsing, listing details and a meetup-information section. Keep the design fast to scan on mobile, and review all safety instructions with campus administrators.
Tradly: Tradly Vibe Coding turns a plain-language description into front-end code connected to live marketplace listings.

Step 5 · AI
Answer common listing and meetup questions
Train an agent on your marketplace rules, prohibited-item policy and meetup guidance. It can explain how to list a book or report a problem. Use a connected assistant to check new listings awaiting approval, while a human reviews safety reports and eligibility decisions.
Tradly: Tradly Agent Builder uses your files, pages and notes to answer questions; Tradly MCP connects supported AI assistants to marketplace activity.

Step 6 · Launch
Pilot with one campus group
Ask a small group of students to list real items, browse categories and contact a seller. Check whether prices, item condition and meetup details are clear. Invite moderators to test the report process, then adjust listing instructions before opening the site to the wider campus.
Tradly: Tradly supports web and native iOS and Android apps, with seller tools, messaging and listings for the pilot.

Questions people ask
Can students sign up using only a university email?
The feature catalog does not list automatic school-email verification. You can define a manual approval process or connect a suitable third-party verification service, then explain how eligibility data is handled.
Can students arrange in-person exchanges?
Yes, students can use marketplace messaging to ask questions and coordinate a handoff. Set clear community safety guidance and suggest public campus locations; the marketplace does not guarantee that an exchange takes place.
Can AI moderate student listings?
An agent trained on your rules can explain what is allowed and help users report a problem. Keep decisions about eligibility, safety reports and removal of listings with a moderator.
