Replai.pm's answer

Replai is the only WhatsApp AI built specifically for small businesses that pairs to your existing WhatsApp Business number in 30 seconds — no Meta API approval, no per-message fees, no developer needed.

Most "WhatsApp automation" tools come in two shapes:

• Official WhatsApp Business API platforms (Wati, Respond.io, Trengo) that require weeks of Meta business verification, sign with a BSP, and pass per-conversation Meta fees through ($0.005–$0.10 per conversation depending on country)
• Developer libraries (WAHA, Baileys) that give you protocol access but make you build everything yourself

Replai is a turnkey product on the device-pairing path. You scan a QR with your existing WhatsApp Business app (same mechanism as WhatsApp Web), drop your menu / FAQ / catalog as a Google Doc, and the AI answers from that knowledge base — in your customer's language, including voice notes and product photos, the moment a message arrives.

Built for the way salons, dental clinics, e-commerce DTC brands, tuition centres, restaurants, and other SMBs in Southeast Asia, the Gulf, and Latin America actually use WhatsApp.

Replai.pm's answer

Pick Replai if your problem is receiving messages faster than you can reply (the dominant SMB pain), and any of these specific constraints matter:

• You don't want to spend 2-4 weeks getting Meta business verification + signing with a BSP
• You'd rather pay one flat monthly than per-conversation Meta fees ($0.005–$0.10 each, country-dependent)
• You want the AI included by default — not as a paid add-on with separate credit caps
• Your customers send voice notes and product photos that you want handled natively (most tools either don't support these or charge for higher AI tiers)
• Your customers write in multiple languages and you want auto-detection per message (English, Bahasa Malaysia, Mandarin, Tamil, Arabic, Spanish, Portuguese)
• You're a small business (1-50 employees) and the WABA + agent-routing + per-seat-licensing complexity of mid-market tools is overkill

Pick a competitor instead if:

• You're running broadcast WhatsApp marketing at scale → Wati, ManyChat, Respond.io
• You need multichannel routing across email + WhatsApp + Instagram for a multi-agent support team → Respond.io, Trengo
• You're a developer building custom WhatsApp integrations and only want the protocol layer → WAHA
• You're in a regulated industry (banking, healthcare, gov) that needs official WABA compliance posture → any BSP-route tool

Replai.pm's answer

Owner-operators and small teams (1-50 employees) running businesses where WhatsApp is the primary customer channel — typically Southeast Asia, the Gulf, Latin America, and other regions where WhatsApp dominates customer messaging.

Specific shapes we see most:

• DTC e-commerce brands (fashion, beauty, F&B, electronics) doing $10K-$500K monthly on Shopify, WooCommerce, or similar
• Beauty salons, dental clinics, gyms, tuition centres with appointment-driven inbound
• F&B operators (restaurants, cafes) handling reservation + menu enquiries on WhatsApp
• Real estate agents, photographers, event planners with high-context client conversations
• Professional services (accountants, insurance agents, lawyers) answering recurring policy questions

What they have in common:

• 50–500 inbound WhatsApp messages per day
• 70% of those messages are the same five questions (price, availability, hours, location, "do you have X")
• No dedicated support team — the owner or reception answers personally between actual work
• Customers writing in mixed languages, sending voice notes, sending product/menu photos

Replai's job is to absorb the repetitive 70% so the owner can spend time on the 30% that actually needs human judgment — complaints, custom orders, wholesale enquiries, edge cases.

Replai.pm's answer

Replai started as a hack the founder built to keep his own small e-commerce business afloat.

He was running a phone-accessories store doing real volume on Shopify + WhatsApp. The inbox was the bottleneck — answering 80–150 customer messages a day, same questions, same screenshots, same voice notes asking about MagSafe and shipping. Replies at 11pm and 6am. Answering while driving (badly). The store was growing, but the support inbox was the constraint — not the product, not the marketing, the inbox.

One night he wired up Claude (Anthropic's API) to read the recent WhatsApp threads and generate replies grounded in the product catalog. Within a week, the bot was handling about 70% of inbound. The 30% that needed a human were the actually interesting messages — wholesale enquiries, damaged-shipment complaints, custom requests. He got his evenings back.

He told some other small-business owners about it. A tuition centre operator answering parent enquiries at midnight. A florist whose voice-note inbox was full of orders she couldn't transcribe fast enough. A friend running a Hari Raya promo who needed to capture contest entries by photo. Same problem. Same channel. Same shape of solution. And none of them were going to write Python to fix it.

So the hack became a product: a pairing flow that doesn't need code (QR scan), a knowledge base that accepts a PDF or Google Doc URL, vertical templates so a clinic owner doesn't have to write a system prompt from scratch, safety-net classifier that flags complaints so nothing festers.

Replai.pm's answer

Core AI stack:

• Anthropic Claude — primary LLM for customer replies, grounded in your knowledge base
• OpenAI Whisper — voice note transcription
• Vision models — for reading product photos, receipts, menu screenshots customers send

WhatsApp integration:

• Baileys — open-source library for the WhatsApp Web protocol (same path most "no Meta API needed" tools use). Replai pairs to your existing WhatsApp Business number as a linked device — same mechanism as WhatsApp Web on your laptop.

Knowledge base:

• Vector embeddings over your uploaded source (Google Doc, PDF, FAQ URL) for grounded retrieval

Application stack:

• Next.js for the landing site + operator dashboard
• PostgreSQL for conversations + lead capture data
• Polar.sh for subscription billing + the conversation-cap accounting

Infrastructure:

• Hostinger VPS for hosting (cost-optimised for SEA/MENA latency)

Safety:

• A second AI quietly classifies every reply for complaints, scams, and abuse — flags surface on the operator dashboard before they escalate
• Ban-mitigation built into the outbound flow: jittered scheduling, per-hour/per-day rate limits, warm-up routine for new numbers, automatic STOP/opt-out handling
