Zero-Hallucination Customer Support
Strict 0.78 vector similarity threshold with confidence gating. Cites original sources and politely defers unanswered queries with 0-token waste. Never promises fake discounts.
Custom RAG Knowledge Ingestion
Automated document parsing for sitemaps, PDFs, and internal manuals into Supabase pgvector HNSW semantic index with Reciprocal Rank Fusion keyword matching.
Why Businesses Choose Saathi
Enterprise Features Built Without Enterprise Overhead
Traditional chatbots hallucinate policies, leak across tenants, and cost a fortune. Saathi Bot solves all three.
Zero-Hallucination Gating
If the similarity score is below the confidence threshold, the bot responds with a safe fallback without invoking the LLM. Never promises fake discounts.
Native Hinglish & Hindi
Multilingual embeddings allow customers to query in colloquial Hindi or Hinglish, while accurately mapping back to English knowledge base documents.
Lightweight Shadow DOM Widget
Single <script> tag embed. Shadow DOM prevents host CSS pollution on Shopify, WordPress, Webflow, or custom React apps.
Hybrid Search + RRF
Combines full-text Postgres tsvector keyword matching with pgvector HNSW semantic embeddings via Reciprocal Rank Fusion.
Active Learning & Semantic Clustering
Clusters semantically equivalent fallback queries (e.g. “prices” vs “cost”) with unified frequency counts. Features 1-click grounded draft answer suggestions.
Allowed Domains & Live Test
Strict database-backed domain allowlist blocks unauthorized embedding. Includes a real-time Origin tester to verify CORS security without leaving the dashboard.
Turn Unanswered Questions into Instant Knowledge
When visitors ask questions your bot can't answer with high confidence, Saathi Bot groups them semantically so you see true topic frequency instead of hundreds of duplicate rows.
Semantic Question Clustering
Combines variations like “how much is it” and “pricing plans” into one single actionable item.
Grounded Answer Suggestions
Runs relaxed retrieval against your existing documents to draft suggested answers for review before saving.
Zero Hallucination Gate
If no related content exists, it refuses to invent answers, prompting the owner to author authoritative content.

Meet the Architect Behind Saathi Bot
Designed, built, and open-sourced by Tushar Singh (Code with Mr Singh) to prove that world-class, zero-hallucination AI customer service doesn't require monthly SaaS gouging or bloated AWS infrastructure.

AI Automation Architect & Full-Stack Systems Engineer
“I built Saathi Bot to eliminate the absurd monthly token markups and hallucinations that plague small businesses and indie developers. Grounded RAG with BYOK is how AI customer support should have been designed from day one.”
What Makes Saathi Bot Different
Key architectural choices made during development to protect privacy, eliminate hallucination, and guarantee production resilience:
Custom Supabase pgvector cosine distance pipeline with 0.78 similarity thresholds. If your docs don't answer it, the bot admits it rather than inventing lies.
Trained prompt architectures for romanized Hindi-English conversations commonly used across India, giving authentic vernacular customer support.
Zero EC2 instances, zero S3 or DynamoDB bill surprises. Pure Vercel Edge runtime and Supabase with pgmq queueing for background document scraping.
Author of open-source TypeScript packages (env-schema-guard, retry-circuit). Transparent codebase released under the permissive MIT License.
