This guide will walk you through registering, choosing an Expert, and starting your first AI conversation in 5 minutes.

​
Before You Begin

All you need is a modern browser (Chrome, Firefox, Safari, or Edge) and a phone number or WeChat account.
1

Register & Log In

Visit app.profy.cn. You can register using either of the following methods:
  • Phone number login: Enter your phone number and receive a verification code to log in (no password required)
  • WeChat QR code login: Scan the QR code with WeChat for one-tap authorization login
New accounts automatically receive 2,000 credits (default; operations can adjust), valid for 90 days, usable across every Expert on the platform.
A daily check-in grants another 200 credits (default). But check-in credits are valid for the calendar day only — cleared at midnight Beijing time rather than 24 hours after the grant — so there is no point stockpiling them.

Browse the Expert Marketplace

After logging in, go to the homepage or click “Marketplace” in the top navigation. You’ll see Experts across various domains:
  • Featured: Quality Experts curated by the platform
  • Browse by Category: Filter by domain — writing, programming, design, data analysis, education, etc.
  • Search: Enter keywords to directly search for the capabilities you need
Each Expert card displays its name, description, rating, and number of users to help you quickly determine if it’s a good fit.

Choose Your First Expert

Click any Expert card to enter its detail page. Here you can see:
  • Overview: Introduction to the Expert’s capabilities and applicable scenarios
  • Pricing: Free or one-time unlock (only these two; a price of 0 means free), plus your remaining trial turns
  • Reviews: Feedback from other users
Choose a free or trial-supported Expert and click “Start Chat”.
Paid Experts grant 3 free trial turns by default (creators can raise this up to 10). Trial turns accumulate per “you × this Expert” and never reset — deleting the session or switching devices will not refill them.
A “free Expert” means the creator charges nothing, not that usage is free. Every turn still deducts credits at your selected model’s rate, because compute cost is incurred in real time. The same holds after unlocking a paid Expert — the unlock fee and the conversation cost are two separate bills.

Start Your First Conversation

After entering the chat interface, you’ll see a chat-like interaction area. The Expert may send an opening message introducing what it can do.The Expert replies in real-time streaming. How you word that first message decides whether it starts working or asks you three clarifying questions:
The rule is simple: put the shape of the deliverable in the first sentence. Goal, constraints, audience, length — give all four and nothing is left to guess.
5

Try Uploading a File

Next to the chat input box, you’ll see a file upload button. Experts can process various file types:
  • Documents: Word, PDF, PPT, Excel
  • Code: Source code files in various programming languages
  • Images: Screenshots, design mockups, photos
  • Archives: ZIP-format project files
Try uploading a file and ask the Expert to analyze or process it.
Per-file limits are set by type and do not vary by plan: images 20 MB, documents 512 MB, code 50 MB. Up to 10 attachments per message.The total storage quota does follow your plan: 10 GB on Free, 15–30 GB on paid tiers. Full inventory in Limits.
6

Explore the Workspace Panel

If the Expert you’re using has the sandbox workspace enabled, a workspace panel will appear on the right side of the chat interface:
  • Code Editor: View and edit code generated by the Expert
  • Website Preview: Preview web pages built by the Expert in real time
  • File Browser: Manage all files in the workspace
  • Terminal: View command execution results
Files in the workspace are persistently saved — close the browser and come back, and your files will still be there.

Useful Tips for Conversations

Plan Mode

Activate Plan Mode from the ”+” menu in the input box. The Expert will first research and create a plan, then execute after your confirmation

Multi-turn Conversations

Experts understand context. You can keep asking follow-up questions and modifying requirements within the same session — the Expert remembers previous content

Select Plugins

Some Experts offer optional plugins (e.g., website building, video production). Enable them as needed from the ”+” menu before chatting

Temporary Chat

If you don’t want the Expert to remember this conversation, you can select “Temporary Chat” mode before starting

What you have on day one

​
Managing Your Credits

Each AI conversation consumes credits, and the amount depends on the model used and the type of interaction. You can check your current credits balance from the avatar menu in the top-right corner. When you’re running low on credits, you can:
  • Upgrade your plan: Plus grants 3,900 / Pro 11,000 / Flagship 30,000 per month
  • Purchase a top-up pack: 100 credits per ¥1, with a 5–12% bonus from the ¥30 tier up
  • Refer a friend: 1,000 credits to each side
Expired credits are neither refunded nor reissued. Four validity windows are worth memorising:
  • Daily check-in — same calendar day (cleared at midnight)
  • Signup bonus — 90 days
  • Plan bonus — one billing cycle (monthly)
  • Purchased credits — never expire
Deduction runs bonus-first, purchased-last, so you never need to plan which batch to spend.
