Frequently asked questions

Can I set up WhatsApp auto reply without the Business API?

Yes. FastLegal links to your own WhatsApp number by scanning a QR code — the same way WhatsApp Web works. No WhatsApp Business API, no Meta verification, no new number. The AI then replies to customers 24/7 in your own style.

Does the WhatsApp AI chatbot reply in Hindi and Hinglish?

Yes. The agent mirrors each customer's language automatically — Hindi, Hinglish, English or any mix — and it learns your personal texting style from your past chats, so replies sound like you, not a bot.

Can it take orders and collect payments on WhatsApp?

Yes. Upload your products or services, and the AI quotes prices, shares photos, records orders, sends your UPI payment QR, reads payment screenshots and marks orders paid — then updates the customer at every step (confirmed, ready, delivered).

Can it send EMI, GST or appointment reminders automatically?

Yes. Add a list with a due-date column (EMI customers, GST clients, appointments) and FastLegal sends WhatsApp reminders before the due date — and for overdue entries — every day, automatically.

Is there a free trial?

Yes — every new account gets a 14-day free trial with all features. Plans start at ₹499/month after that.

What happens when the AI doesn't know an answer?

It never invents details. It tells the customer it'll check, and messages you privately on your own WhatsApp with the customer's name and question — reply to that message and FastLegal forwards your answer to the customer, written naturally.

Stop leaving clients on read.

Recent agent activity

Inbox

Every conversation your agent is having. Open one to read it or jump in yourself — your replies send from your WhatsApp.

⏸ Agent paused

Replying here pauses the agent for this chat for 30 minutes so it doesn’t talk over you — use the menu above to resume or pause longer.

Your WhatsApp

Link your own number — scan with WhatsApp → Linked devices → Link a device.

Status: idle
WhatsApp QR code

QR refreshes automatically.

When the agent needs you, it messages your own WhatsApp (the “message yourself” chat) with the client’s name & number. Just reply to that message — or send “number: your reply” — and we’ll forward it to that client for you.

Data Lists

Create lists of anything — products, services, customers, leads, EMI/loan schedules. Tell the agent how to use each list and it answers clients from it; lists with a due date can send automatic reminders.

Start from your business — comes with sample items you can change:
Due-date reminders (optional)

Overdue rows are reminded too. Add a column with the number to message and the due date.

Rows

Add a row
Or paste many rows at once (CSV)

CRM & Leads

Everyone who messages you on WhatsApp is captured here as a lead and moves through your pipeline. When they place or pay for an order, they’re converted to a customer automatically. Message people by stage with templates tuned to your business.

Stage messages — write once, send to a whole stage

Use {name} for the contact’s name and {business} for your business name.

Orders

Orders your agent has taken. Move them along — new → confirmed → paid → ready → delivered — and the client is messaged automatically at each step.

Billing

Monthly

Yearly 2 months free

Payments are processed securely by Razorpay. Your plan activates instantly after payment.

🛡️ Admin

Platform keys

Set once here — they apply instantly, no redeploy. Values are encrypted; existing secrets show as “set”. Leave a field blank to keep it, or submit an empty value to clear it.

Users

Team

Give your staff access to this workspace without sharing your login. Operators can work the inbox, orders, lists and CRM; viewers can only look. Only you can change settings, billing and the team.

Ask them to sign up at this site with that exact email — they'll land in your workspace automatically. Use an email that isn't already a FastLegal owner account.

Payment QR

Upload your payment QR (UPI / bank). When a client is ready to pay, the agent sends them this QR to scan — no payment gateway needed.

Payment QR

No QR uploaded yet.

Tell the agent when to send it — e.g. in a list's instructions: “after the client confirms an order, send the payment QR”.

When a client sends a payment screenshot, the agent reads it — if it shows a successful payment it marks the order paid and pings you to verify. (Reading images needs the Claude provider.)

Persona & Instructions

Identity
How it talks

It always mirrors the client's language — replies in Hindi/Hinglish if they do.

Quick Answers

Set up common questions and a short answer for each — office address, documents required, pricing, email, website, or anything you like. You only need the basic facts; the agent answers in its own words and the client's language.

AI Provider

Provider & key

The agent uses the key for the selected provider. Save both, switch anytime.

Stored encrypted. Leave blank to keep the current key.

Get one at platform.deepseek.com. Stored encrypted.

Save first, then test the key stored for the selected provider.

Replies & Follow-ups

Replies

Add numbers with or without the country code — both match. Applies to auto-replies and follow-ups.

The agent waits a random pause in this range after the client's last message — so if they send several texts in a row, it reads them all and replies once, in context. Feels human, not instant. Set both to 0 to reply immediately.

Follow-ups

When you replied last and the client hasn't answered in this many hours, the agent sends one gentle, natural nudge in your style.

Integrations (optional)
