Built around your business knowledge
Connect menus, product catalogs, services, listings, policies, or your own API. Choose the fields that matter. Build an assistant grounded in your business—not a template for someone else’s industry.
Start free · Documents + websites + JSON APIs · You choose what your bot knows
Illustrative offline examples · Your own API fields are configured in the app.
Product
Your industry defines the knowledge. You define the audience and voice. Contextr connects your information, grounds answers in it, and helps you find what is missing.
How it works
Add documents, your website, or a read-only JSON API. Menus, catalogs, courses, services: start with the information your business already has.
PDF · DOCX · CSV · TXT · Websites · JSON APIs
Preview the data, map the fields in your own words, and approve what your bot can use. Knowledge is indexed for meaning and exact terms.
Custom fields · Preview · Tenant-scoped retrieval
Test your bot against real questions and refresh your knowledge as it changes. Third-party REST API integration is coming first.
Grounded answers · Saved conversations · Usage tracking
Live playground
Explore sample industries with different knowledge. These examples run offline; your own bot uses the documents and API fields you publish. Ask something unsupported and watch it decline to guess.

This demo runs entirely in your browser on sample documents. Nothing you type is sent anywhere.
Use cases
Menus
Ingredients, options, and prices
Connect your menu API or approved information. Answer dining questions from the fields you publish; refresh as your menu changes.
Catalogs
Products, variants, and specifications
Bring product details and policies into one knowledge base. Keep personal orders and live stock behind separately authorized systems.
Services
Offerings, eligibility, and policies
Explain what you offer using your own service records, guides, and FAQs—not a generic industry template.
Courses
Programs, requirements, and fees
Use approved course data and guidance to answer questions for your institution’s audience.
Examples, not restrictions. Custom fields and business purposes work without an industry template.
Security & trust
We built isolation into the foundation, not bolted it on later. Here is exactly what that means.
Every request, database query and vector search is scoped to your company. Each layer checks it independently.
Documents, vectors and conversations are stored and processed in Indian data centres.
Export or permanently delete everything (files, vectors, chats) with one request.
TLS in transit, AES-256 at rest. API secrets are hashed, shown once and can be rotated any time.
Key creation, rotation and document deletion are recorded with who, what and when.
Your documents answer your customers. They are never used to train shared models.
Developers
REST APIs are our first third-party integration. Use scoped server-side keys, document access and streaming chat to connect Contextr to your own stack.
