Questions & Answers

As answered by people managing PropelAI Studio and Diffee.

What makes your product unique?

PropelAI Studio's answer

One tool for the entire client workflow: AI proposals, contracts with e-signatures, and invoices that collect payment — including Paystack (card, bank transfer, USSD) for African and emerging markets, alongside Stripe and PayPal. When payment lands, the invoice automatically becomes an official receipt. No stitching together a proposal app, an e-sign tool and an invoicing tool.

How would you describe the primary audience of your product?

PropelAI Studio's answer

Freelancers, consultants and small agencies (1–10 people) worldwide — especially in Nigeria, Africa and other emerging markets, where clients commonly pay by bank transfer or USSD and USD subscription prices are a real barrier.

What's the story behind your product?

PropelAI Studio's answer

Built solo from Abuja, Nigeria by Ayorinde Ajayi — a petroleum engineer who spent 5+ years in business development and sales before teaching himself to code. He kept watching talented freelancers lose clients to slow paperwork: slow proposals, unsigned contracts, unpaid invoices. PropelAI Studio is the tool he wished existed — launched on Product Hunt in September 2026.

Which are the primary technologies used for building your product?

PropelAI Studio's answer

React + TypeScript frontend, Tailwind CSS, Vite, serverless Netlify Functions (Node.js), Supabase (PostgreSQL), Resend for transactional email, Paystack/Stripe/PayPal payment integrations, fast Groq-powered AI generation, and an official Zapier integration.

Who are some of the biggest customers of your product?

PropelAI Studio's answer

PropelAI Studio is young (launched 2026) and serves individual freelancers and small agencies rather than big brands — designers, writers, consultants and developers across Africa and beyond.

Why should a person choose your product over its competitors?

PropelAI Studio's answer

PropelAI Studio combines proposals, e-signatures and invoices in one place. The free plan includes 3 AI generations with no card needed. Pro is a founding special at $8/month (₦11,000/month in Nigeria). Invoices can be paid by card, bank transfer or USSD through Paystack, and by Stripe or PayPal.
