# Upload your document
client.rag_upload("Q3 financial report...", "report.txt")

# Ask a question — get a verified answer
result = client.rag_query("What was the Q3 revenue?")

print(result.answer)       # "$47.3 million"

Why teams switch to Wauldo

Without Wauldo
  • Manage 5+ provider APIs separately
  • No fallback when a model fails
  • LLM invents plausible-sounding facts
  • Hard to track cost, latency, accuracy
  • Build retry, rate limiting, caching yourself
With Wauldo
  • One API — best model auto-selected per query
  • Built-in fallback — transparent provider failover
  • Every answer verified — citations + confidence score
  • Audit trail included — model, latency, grounded status
  • Production-hardened — retry, rate limiting, tenant isolation

When evidence is weak, we say so.

If the documents don't contain enough evidence, we return:

  • Low confidence score
  • grounded: false
  • Or no answer at all

So your users never get misleading information.

TRUSTED ANSWER
"answer": "Q3 revenue was $47.3M"
"confidence": 0.92
"grounded": true
"sources": [2 passages, 87% match]
UNVERIFIED — REJECTED
"answer": "Insufficient evidence to answer"
"confidence": 0.23
"grounded": false
"sources": [0 relevant passages]

Built for production AI systems

Every feature exists to save you time, money, or risk.

Zero Hallucinations

Your users never get misleading information. Every answer is verified against source documents before being returned.

Full Audit Trail

Know exactly why each answer was generated. Source passages, confidence scores, model used, latency — on every response.

Cut Costs Automatically

Intelligent routing picks the cheapest model that meets quality requirements. Simple questions don't need GPT-4.

Never Go Down

Built-in fallback across 5+ providers. If OpenAI is slow, your request automatically routes to the next best model.

Switch in 2 Lines

OpenAI-compatible API. Change your base URL, keep your existing code. Zero migration effort.
