I will build an ai customer support agent for live chat widget, whatsapp and slack


About this gig
I build custom AI support systems using n8n, PostgreSQL with pgvector, and OpenAI, giving you full ownership of your automation, data, and workflows. Theres no vendor lock-in, no black-box platform, and no recurring conversation fees beyond your own AI usage.
Your AI assistant can answer customer questions using your documentation, FAQs, knowledge base, and past support tickets. When it can't answer with confidence, it automatically creates a support ticket so no customer is left behind.
- 24/7 AI customer support
- RAG-powered knowledge retrieval
- Hybrid search (vector + keyword) for accurate answers
- Website chat widget, Slack, and WhatsApp integration
- Automatic ticket creation and escalation
- Easy knowledge management (upload files, spreadsheets, or add content manually)
- Editable n8n workflow (JSON) included
- Self-hosted solution with full ownership of your data
- Perfect for SaaS companies, startups, agencies, and businesses looking to reduce support workload, improve response times, and own their AI support system instead of paying ongoing subscription fees.
Message me before ordering if you need a custom workflow or integration.

FAQ
Do I need to already have n8n and a Postgres database set up?
No. I'll guide you through getting both running (n8n Cloud or self-hosted, and a free-tier Postgres from Supabase or Neon both work great), and provide the full database schema ready to run.
What if I don't have technical knowledge of n8n?
You don't need to build anything yourself — I deliver working, imported workflows. You'll just need to plug in your own API keys and credentials (I provide exact step-by-step instructions for this).
Does this use my own OpenAI account?
Yes — you keep full control of your AI usage and costs, and can swap the model at any time. I don't take a cut of your ongoing API spend.
What do you need from me to get started?
Your existing docs/FAQs/support content (any format), and access to create accounts for n8n, a Postgres provider, and OpenAI if you don't already have them.
Do you offer support after delivery?
Yes — Premium includes 14 days of bug-fix support. Extended support or new feature work can be arranged separately.
