Workflow
From source coverage to controlled customer answers.
Use this workflow to compare whether a tool can be operated safely after launch.
Step 1
01Connect the knowledge that should ground the answer
Corthex indexes files, URLs, product context, and operational policies so the assistant has a controlled evidence layer before it ever speaks to a visitor.
- Upload documents, paste text, or import URLs.
- Chunk and embed content for vector retrieval.
- Keep source names available for answer citations.
Step 2
02Answer with retrieval, page context, and tool policy
The assistant combines the user's message with relevant knowledge, current page context, and enabled tools such as commerce lookup or live site lookup.
- Prefer exact source matches before general model knowledge.
- Route unclear or risky questions to fallback behavior.
- Show source-backed answers when evidence is available.
Step 3
03Escalate, measure, and improve the coverage loop
Human teams can take over live conversations, review unresolved questions, and turn gaps into new knowledge sources or better prompts.
- Use staff handoff for high-intent or complex conversations.
- Track questions, leads, contact history, and usage.
- Improve source coverage from real support demand.
Decision frame
Compare the workflow, not just the chatbot label
When comparing Corthex and Zendesk AI, focus on how each system gets evidence, shows sources, routes uncertain conversations, and helps teams improve the knowledge base after launch.
- Does the assistant cite or expose source context?
- Can staff take over without losing conversation history?
- Can developers embed or stream the assistant where they need it?
Corthex fit
Choose Corthex when source control is the buying criterion
Corthex is intentionally positioned around grounded support: RAG knowledge sources, citations, page context, live lookup fallback, staff handoff, analytics, and developer APIs.
- Best for support and commerce teams with content-heavy answers.
- Useful when operators need to review unresolved questions.
- Strong when widget, API, and human support must stay connected.
Procurement checklist
Questions to ask before switching or buying
Use a consistent checklist across vendors so the comparison is based on operational fit rather than brand familiarity.
- How does the assistant ground answers and expose evidence?
- How are escalations, leads, and staff replies handled?
- What limits, pricing units, and API restrictions apply?
FAQ
Questions this page should answer clearly.
Is Corthex a Zendesk AI replacement?
It depends on your workflow. Corthex is focused on source-grounded AI assistants, website widgets, commerce-aware chat, developer APIs, and staff handoff rather than replacing every part of a large support suite.
What should I test in a proof of concept?
Test real support questions, stale or conflicting policy content, product-page questions, escalation requests, API usage, and how quickly your team can identify missing knowledge.
Why compare source citations?
Source citations make it easier to inspect why an assistant answered a certain way, improve weak sources, and give support teams confidence in customer-facing responses.
Does Corthex support ecommerce workflows?
Yes. Corthex includes storefront-oriented widget and connector flows for product-aware support, especially around WooCommerce and PrestaShop use cases.
