Build or buy / Support
AI support chatbot
Build a retrieval-based assistant with your own data, or buy managed reliability and helpdesk integrations.
Short answer
A narrow assistant over well-maintained documentation can be economical to build. Buy when escalation, analytics, multilingual support, quality control, and helpdesk integrations matter from day one.
What a good-enough build includes
- Documentation ingestion and chunking
- Search and grounded answer generation
- Citations back to source content
- Basic feedback and escalation
- Usage and cost limits
The expensive edge cases
Evaluation, prompt-injection defenses, stale documentation, access control, analytics, and reliable human handoff are where a prototype becomes an operational system.
Who should build
Technical teams with a bounded knowledge base, existing authentication, and the ability to monitor answer quality continuously.
