I am seeking a freelance developer to create a small FAQ assistant web application utilizing Retrieval-Augmented Generation (RAG). This project is paid and will serve as a practical evaluation for potential longer‑term work on similar AI features. What we need built - A simple [login to view URL] web app (App Router, TypeScript preferred) with: • One page containing: A text input/textarea for a user question. A submit button. An answer area directly under the input, with clear, modern styling. - A backend route (e.g., app/api/ask/[login to view URL]) that: • Accepts a JSON payload { question: string }. • Uses local text embeddings (e.g., @xenova/transformers or similar) to find relevant snippets from a small docs/ folder. • Calls the Perplexity AI Chat Completions API (e.g., sonar model, set via environment variable). • Returns a JSON response containing the generated answer and the sources used. - A simple indexing step/script to: • Read the docs. • Split them into chunks. • Compute and store embeddings for retrieval (e.g. in a JSON file). Deliverables - Git repository with: • Frontend and backend code. • A docs/ folder with example content. • A short README explaining: o Set up and installation. o Required environment variables (Perplexity API key, model name). o How to build the index and run the app locally. Brief note on your design decisions and possible next improvements (1–2 paragraphs). Required skills - Strong experience with [login to view URL] and React. - Familiarity with calling external APIs (REST) and handling JSON. - Basic understanding of vector embeddings and RAG is a plus (or willingness to learn). Payment & evaluation - This is a paid fixed‑price project, not an unpaid test. - Successful completion with clean, understandable code and clear documentation may lead to follow‑up projects and ongoing work.

Hello, I’ve read your RAG FAQ assistant brief and can build a compact, maintainable [login to view URL] (App Router) app in TypeScript that answers questions from a local docs/ folder. I’ll implement a single page with a textarea, submit button and a clear answer area, and an API route (app/api/ask/[login to view URL]) that accepts question , retrieves relevant chunks using local embeddings (for example @xenova/transformers), calls the Perplexity Chat Completions API (model via env var), and returns answer plus sources. I will provide an indexing script to chunk docs, compute embeddings and store them in a JSON file, plus a README with setup, env vars and run instructions. Design notes: I’ll keep the frontend minimal and accessible with scalable state handling, and the backend modular so swapping vector stores or models is straightforward. Next improvements would be secure caching, incremental index updates and improved chunking/semantic search tuning. I can start by confirming the Perplexity model you prefer and any constraints on docs size. Do you have a preferred Perplexity model name, max docs size, or an example doc you want included in the initial index? Best regards, Fabian

Hey there, I can help you to make an RAG based FAQ assistant, I have made one earlier and can help you to make one for you. I will be using nextjs, but for training and building, I will be using python, any maybe for api too. DM me to discuss more.

Hi there This build depends on keeping the RAG flow simple and reliable, with fast retrieval from local docs and a clean answer path through the API. The main risks are weak chunking, poor snippet matching, slow local embeddings, unclear source output, and an API route that works in dev but is hard to run locally. In the first hour I will set up the App Router page and ask route, then build the indexing script and test retrieval quality on a small docs set before wiring the final response format. Should retrieval stay fully file based with embeddings saved to JSON, or are you open to a lightweight vector store later? Do you want the answer to cite exact chunk text or only source file names? I have built small AI tools where the key was clean retrieval, readable code, and a README another developer could run without guesswork. I can start right away and keep it clean and practical. Hope to discuss more on chat. Mykola Nahurskyi

Hello, Will the web application need to handle concurrent user queries efficiently to ensure smooth user experience? Are there any specific security requirements that need to be implemented to protect user data during the question-answer process? I take full ownership of the development process, ensuring stable and production-grade delivery. Communication will be direct and efficient throughout the project. Let’s align on the details and move forward. Best regards, Vitalii

Hi there, THE CHALLENGE is integrating the RAG model effectively to provide accurate answers to user questions by leveraging local text embeddings and the Perplexity AI Chat Completions API. Ensuring seamless communication between the frontend and backend, as well as optimizing the indexing process for efficient retrieval of information, will be key technical hurdles to overcome. I will approach this by meticulously testing each component, debugging any issues that arise, and continuously refining the system to enhance performance and user experience. Regards, Matheus

⚙️ I'm available to start right away. ⚙️ Your main challenge is getting a clean, minimal RAG FAQ app that’s easy to run, read, and extend later. You also want this to be a real signal of how someone will work with you long term, not just a throwaway demo. ✔️ Communication / Customer Interaction I’ll confirm the flow (question → retrieval → Perplexity answer → sources) before coding. You’ll get short, focused updates and can review progress in small, working increments. ✔️ Process Tracking / Organization / Reporting I’ll structure the app with a clear API route, a simple indexing script, and a tidy docs/ folder. The README will walk through setup, env vars, index building, and running locally, plus a brief note on design choices and next steps. ✔️ Reliability / Consistency / Proactive Communication I’ll keep the code small, readable, and well‑named so future features are easy to add. Any trade‑offs will be documented. I’d be glad to build this first version and set a solid base for future work together. Hermann M.

Hi Amigo, I can build your project. I've delivered similar AI-powered apps, like a React-based search tool with local embeddings that cut API costs by 40% while boosting response relevance on internal docs. For this, I'll implement a clean indexing script splitting docs into 500-token chunks, storing embeddings in a JSON vector store; the /api/ask route will embed the question, cosine-similarity search top-3 matches, and prompt Perplexity with context + sources for transparency. Your repo will include styled UI (Tailwind for modern input/answer layout), TypeScript throughout, example docs/, full README with env setup (PERPLEXITY_API_KEY, MODEL), index build command, and notes on scaling. Let's hop on a quick call to review your docs format and kick this off-when works for you?

Hi, I’ll build a clean, maintainable RAG-style FAQ system using TypeScript. It will generate local embeddings with @xenova/transformers, store them in a simple JSON index, and retrieve the top-3 relevant chunks using cosine similarity. The API will process questions, fetch context, and call Perplexity Sonar to return answers with sources. A minimal Tailwind frontend and an indexing script for the docs folder will be included. Delivery in 3 days for $220, with clear documentation and notes for future scaling. Looking forward to working together.
