Hello, Your description cuts off, but I'm catching something important: most chatbot projects fail because teams focus on the AI first and user experience second. Before we talk NLP models, we need to nail what "answering users" actually means in your workflow — are you handling FAQs, complex multi-turn conversations, integrations with external data, or something else entirely? We've built conversational AI and backend systems for SaaS platforms over the last decade. Python, Java, API architecture, NLP pipelines — we've shipped this stack across dozens of projects. We know the gap between a chatbot that technically works and one that actually solves your users' problems. The 15-25 range is a starting point. Once you clarify scope — especially around data sources, conversation complexity, and whether you need integrations — I'll give you a real number that matches the actual work. Let's hop on a quick call so I can ask the right questions about your use case. No pressure, just want to make sure we're building the right thing. Message me whenever you're ready. Regards, Nurul Hasan

Interesting project, I will build your Q&A chatbot — NLP intent extraction, knowledge base retrieval, fallback logging, and a clean webhook API ready to plug into any frontend or messaging platform. For a 100-question test set at this scale, I would use a RAG approach with a lightweight vector store over your curated content, falling back to an LLM only when confidence is low. This keeps responses fast and accurate while minimizing API costs. Questions: 1) Is your knowledge base already drafted, or do we need to build it together? 2) Do you have a preferred cloud provider for deployment? Looking forward to potentially working together. Thanks, Kamran

Hi, You have written one of the clearest briefs I have seen for this kind of project. You know what you want, you have defined acceptance criteria, and you are not asking for bells and whistles in the first release. That makes this a project I can commit to confidently. Here is how I would approach it. For the NLP layer I would build on a Python stack using LangChain with a retrieval-augmented generation setup rather than Rasa or Dialogflow. The reason is simple. You mentioned pulling answers from a curated knowledge base, and RAG handles that better than intent-based frameworks for a Q&A use case. Your knowledge base lives in structured documents or markdown files, gets indexed into a vector store like Chroma or Pinecone, and the model retrieves the most relevant context before generating a response. This is also what makes the 90 percent accuracy target realistic on a broad question set, because the bot is grounding its answers in your actual content rather than guessing. For the API layer I would build a clean FastAPI service with well-documented endpoints. Dropping it into a website widget or a messaging platform like Slack or WhatsApp would be a matter of pointing the webhook at the right URL, nothing more. The architecture is channel-agnostic from day one, so voice or additional integrations later would not require any rethinking. Looking forward to hearing from you.

@DeveloperStation

Hi there, We’ve developed several AI-driven personal assistants that excel at answering user questions accurately and quickly. For example, we created a product called ConvoAI, which uses LLMs to summarize meetings and extract actionable insights. We also built a custom LLM-based solution for a client that answers questions based on internal documents, achieving over 90% accuracy. With our extensive experience in both LLMs and traditional NLP, we can deliver a robust solution that meets your needs. We can use Rasa or Dialogflow for intent extraction and combine it with LLMs for a more reliable answer. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. Best, Adil

@Mobilehead

Hello, I will build a fast, reliable AI personal-assistant chatbot that understands natural language, extracts intent, and finds answers from a curated knowledge base or an external LLM. I will deliver a robust NLP pipeline (Rasa or custom Python), a secure webhook API, simple JSON/MD content editing, fallback logic, and logging for missed queries. You will get a cloud sandbox deployment, commented source code with a short README for setup and training, and one brief hand-off screen-share, and I will aim to meet at least 90% on your 100-question test with responses under two seconds. Best regards, Sherman.

@slavkom1

Hello, The main thing here is keeping the Q&A path boring and reliable. The fallback and missed-query logging matter more than adding extra assistant features too early. I’ve built Python chatbot/API systems with LLM fallback, curated knowledge files, intent routing, and deployment handoff docs. - Build a text-only assistant with a clean Python API/webhook layer - Use JSON or MD knowledge files so answers can be updated without code changes - Add intent matching plus external LLM fallback when confidence is low - Log unanswered or weak-confidence queries for review - Deploy to a cloud sandbox and include README setup, training, and deploy steps - Run against your 100-question test set and tune toward the 90% target I can start right away and keep the first version focused on response speed under two seconds for normal queries. For the 100-question acceptance test, will the expected answers be exact-match style, or should the evaluator allow semantically equivalent answers with different wording? Regards, Slavko
