How to debug AI chatbots with Preswald

Category: Use Case
AI chatbots are at the core of customer support, financial dispute resolution, and automated workflows. But when they fail - misclassifying intents, generating incorrect responses, or responding too slowly - debugging the issues can be frustrating and time-consuming.
With Preswald, you can analyze chatbot logs, uncover key insights, and troubleshoot performance issues in an interactive data app.
Your fintech chatbot handles fraud dispute reports, predicting user intent (e.g., fraud dispute, transaction check, account lock). Here’s what can go wrong:
- 🔴 Misclassified intents – AI assigns the wrong category to a user request
- 🔴 Slow response times – Chatbot responses take too long
- 🔴 High escalation rates – AI fails to resolve cases, requiring human intervention
- 🔴 Poor response quality – AI replies are vague, inaccurate, or misleading
Step 1: Install and Set Up Preswald
pip install preswald
Initialize a new Preswald project:
preswald init chatbot_debugger
cd chatbot_debugger
This creates a boilerplate project with all necessary config files.
Step 2: Load and Explore Chatbot Logs
Your chatbot logs user queries in a structured format like this:
Timestamp | User_ID | Query | Predicted_Intent | AI_Response | Response_Time (s) | Escalated | Sentiment | Resolution_Status |
---|---|---|---|---|---|---|---|---|
2025-03-10 14:12 | 10432 | "I didn’t authorize this charge." | Fraud_Dispute4 | "Disputing the charge now." | 1.2 | No | Positive | Resolved |
2025-03-10 14:15 | 20411 | "Someone stole money from my account!" | Account_Lock | "Please verify your identity." | 2.8 | Yes | Negative | Escalated |
2025-03-10 14:20 | 30521 | "Was my card used at a gas station?" | Transaction_Check | "You can view your transactions in the app." | 1.5 | No | Neutral | Resolved |
Connect to Data Source
Add your chatbot logs as a data source in preswald.toml
:
[data.chatbot_logs]
type = "csv"
path = "data/chatbot_logs.csv"
Then, load the dataset in your app:
from preswald import connect, get_df, table
connect() # Load data sources from preswald.toml
df = get_df("chatbot_logs")
chatbot_logs = get_df("chatbot_logs") # Load chatbot logs as DataFrame
table(chatbot_logs, title="Chatbot Logs")
Step 3: Identify and Debug Chatbot Failures
1️⃣ Detect Misclassified Intents
Analyze how often the chatbot assigns incorrect intents.
from preswald import query, table
sql = """
SELECT
Predicted_Intent, COUNT(*) as Count
FROM chatbot_logs
GROUP BY Predicted_Intent
ORDER BY Count DESC
"""
intent_distribution = query(sql, "chatbot_logs")
table(intent_distribution, title="Chatbot Intent Distribution")
💡 Fix: If fraud-related queries are often classified as "Account Lock," retrain the AI model with better labeled data.
2️⃣ Measure Chatbot Response Times
Identify cases where the chatbot is too slow.
from preswald import query, plotly
import plotly.express as px
sql = """
SELECT Response_Time FROM chatbot_logs
"""
response_times = query(sql, "chatbot_logs")
fig = px.histogram(response_times, x="Response_Time", title="Chatbot Response Time Distribution")
plotly(fig)
💡 Fix: If response times exceed 2 seconds, optimize database calls, model inference, or server performance.
3️⃣ Track Escalation Rates
Measure how often the chatbot fails to resolve cases and escalates to human agents.
sql = """
SELECT
Escalated, COUNT(*) as Count
FROM chatbot_logs
GROUP BY Escalated
"""
escalation_stats = query(sql, "chatbot_logs")
table(escalation_stats, title="Chatbot Escalation Rate")
💡 Fix: If escalation rates are high, improve chatbot decision-making by fine-tuning the AI model.
4️⃣ Evaluate AI Response Quality
Check sentiment analysis on chatbot responses to gauge user satisfaction.
sql = """
SELECT Sentiment, COUNT(*) as Count
FROM chatbot_logs
GROUP BY Sentiment
"""
sentiment_stats = query(sql, "chatbot_logs")
table(sentiment_stats, title="User Sentiment Distribution")
💡 Fix: If many responses are negative, improve response quality by adding more empathetic, context-aware replies.
Step 4: Deploy and Share Your Debugging App
Once your chatbot debugging dashboard is ready, deploy it:
preswald deploy --target structured --github <github-username> --api-key <structured-api-key>
🔗 This creates a live dashboard where your team can monitor chatbot performance and debug failures in real-time.
With Preswald, you can quickly:
- Load chatbot logs into an interactive dashboard
- Analyze misclassifications, response times, and escalation rates
- Detect negative sentiment and improve chatbot responses
- Deploy a cloud-based debugging app in one command
