Built around your business knowledge

Your knowledge.
Your bot.

Give your bot the documents, websites, and tools your business already uses. It answers from your knowledge and connects to your MCP servers for live lookups and actions.

Knowledge Gap Autopilot

Questions your bot couldn’t answer get grouped by meaning, with a drafted answer from your docs. Approve once and every future visitor gets it.

Contextr reads the tools your MCP server exposes

Your tools, inside the conversation

Connect an MCP server or define an HTTP action. Let the bot look up live information and ask for confirmation before running a write action.

Bot Exam

Before you go live, we test your bot with real questions and show which ones it gets wrong, and why.

Employee-Handbook.pdf

  • Probation lasts 6 months.
  • Notice period: 30 days.
  • Reviews happen each April.

Offer-Letter-Template.docx

  • Joining bonus is paid in month 3.
  • Notice period: 60 days.
  • Benefits start on day one.

Conflict found: notice period is 30 days in one document and 60 in the other.

Contradiction Detector

When two of your documents disagree, we flag it before your bot has to pick one in front of a customer.

“मुझे साल में कितनी sick leave मिलती है?”

Customers send a WhatsApp voice note in Hindi, Tamil, Telugu or English. They get the answer back in their own language.

MCP connections

Answers from your knowledge. Actions through your tools.

Connect a server that supports the Model Context Protocol (MCP) to give your bot access to live information and business actions. Keep your existing systems and bring their tools into the conversation.

  1. Connect your MCP server

    Add its HTTPS address, describe what it does, and supply a token or variables if needed. Contextr discovers the tools it exposes.

  2. Choose what the bot can use

    Review the discovered tools, test them with sample inputs, and enable the ones you want. Mark tools that change data as write actions.

  3. Keep the visitor in control

    The bot uses relevant tools as the conversation develops. Write actions wait for the visitor’s confirmation before they run.

Build a bot with your tools

Have a REST endpoint instead? Define an HTTP action with the same testing and confirmation flow.

I’ll check the menu and pickup options, then show you the order to confirm.

Credentials and variables stay on the server. Tool calls and their outcomes are recorded with the conversation.

How it works

From your data to useful answers.

  1. 01

    Connect your knowledge

    Add documents or your website. Menus, catalogs, courses, services: start with the information your business already has.

    PDF · DOCX · CSV · TXT · Websites

  2. 02

    Add the tools it needs

    Answers are grounded in your knowledge. Connect an MCP server or HTTP action when the bot needs live information or a way to act.

    Test, embed, refresh

    Test real questions and tool calls in the playground. Embed your bot on your website or use the REST API, and keep its knowledge and tools up to date.

Don’t take our word for it. Ask.

Explore sample industries with different knowledge. These examples run offline; your own bot uses the documents you publish. Ask something unsupported and watch it decline to guess.

Use cases

Any industry. Your information, your way.

Restaurants & hospitality

Menus

Ingredients, options, and prices

Answer menu questions from your documents. Connect ordering or booking tools through MCP for live availability and confirmed requests.

Ecommerce & retail

Catalogs

Products, variants, and specifications

Explain products and policies from your knowledge base. Connect tools for stock checks and order status, with verification for personal information.

Services & professional teams

Services

Offerings, eligibility, and policies

Explain what you offer using your own service records, guides, and FAQs—not a generic industry template.

Education

Courses

Programs, requirements, and fees

Use approved course data and guidance to answer questions for your institution’s audience.

Examples, not restrictions. Any business purpose works without an industry template.

Security & trust

Your knowledge stays yours.

We built isolation into the foundation, not bolted it on later. Here is exactly what that means.

API GUARDDATABASEVECTOR STORE

  • Tenant isolation, three times over

    Every request, database query and vector search is scoped to your company. Each layer checks it independently.

  • Data stays in India

    Documents, vectors and conversations are stored and processed in Indian data centres.

  • DPDP Act & GDPR ready

    Export or permanently delete everything (files, vectors, chats) with one request.

  • Encrypted everywhere

    TLS in transit, AES-256 at rest. API secrets are hashed, shown once and can be rotated any time.

  • Audit logs

    Key creation, rotation and document deletion are recorded with who, what and when.

  • Your data trains nothing

    Your documents answer your customers. They are never used to train shared models.

Developers

Your knowledge. Your application.

Need more than the website widget? Use scoped server-side keys, document access and streaming chat to connect Contextr to your own stack.

# Create a scoped key in API & Keys.# Keep your API key on your backend. # 1. Choose your botcurl "$CONTEXTR_API_URL/v1/bots" \  -H "Authorization: Bearer $CONTEXTR_API_KEY" # 2.

REST API · v1

Connect your app and your tools

Use the REST API to call Contextr from your backend. To let Contextr call your systems, connect an MCP server or define an HTTP action in your bot’s Actions tab.

  • GET/v1/bots

    Choose a bot from your workspace.

  • POST/v1/bots/:botId/documents

    Upload your knowledge.

  • GET/v1/bots/:botId/documents

    Check when documents are ready.

  • POST/v1/chat

    Stream grounded answers to your app.
