Alchemyst AI - AI-Native Context Management Platform

What You’re Building

An AI that answers questions using YOUR documents instead of guessing. Before Alchemyst:

const answer = await llm.generate("What's our refund policy?");
// "I don't have information about your specific refund policy..." ❌

After Alchemyst:

const answer = await llm.generate("What's our refund policy?");
// "We offer a 30-day money back guarantee. Contact support@example.com..." ✅

Prerequisites

Alchemyst account (sign up)
Your ALCHEMYST_AI_API_KEY
Node.js 18+ or Python 3.9+

Time to complete: 10 minutes

Step 1: Install

npm install @alchemystai/sdk

pip install alchemystai

Step 2: Initialize

import AlchemystAI from '@alchemystai/sdk';

const client = new AlchemystAI({
  apiKey: process.env.ALCHEMYST_AI_API_KEY,
});

import os
from alchemyst_ai import AlchemystAI

client = AlchemystAI(
  api_key=os.environ.get("ALCHEMYST_AI_API_KEY")
)

Step 3: Store a Document

const result = await client.v1.context.add({
  documents: [{
    content: "Our refund policy: We offer a 30-day money back guarantee. Contact support@example.com to request a refund."
  }],
  context_type: 'resource',
  source: 'documentation',
  scope: 'internal'
});

console.log(`✅ Stored ${result.documents?.length || 0} documents`);
// Output: ✅ Stored 1 documents

result = client.v1.context.add(
  documents=[{
    "content": "Our refund policy: We offer a 30-day money back guarantee. Contact support@example.com to request a refund."
  }],
  context_type="resource",
  source="documentation",
  scope="internal"
)

print(f"✅ Stored {len(result.get('documents', []))} documents")
# Output: ✅ Stored 1 documents

What just happened:

Your document was chunked into searchable pieces (~500 word chunks)
Embeddings were generated automatically (vector representations)
Everything is indexed and ready to search

Verify it worked:

Visit platform.getalchemystai.com/context
You should see your document listed
Click to view chunks and metadata

Step 4: Search for Context

const userQuestion = "What's your refund policy?";

const { contexts } = await client.v1.context.search({
  query: userQuestion,
  similarity_threshold: 0.7,
  scope: 'internal'
});

console.log(`Found ${contexts?.length || 0} relevant chunks`);
// Output: Found 1 relevant chunks

console.log(contexts[0].content);
// Output: "Our refund policy: We offer a 30-day money back guarantee..."

user_question = "What's your refund policy?"

result = client.v1.context.search(
  query=user_question,
  similarity_threshold=0.7,
  scope="internal"
)

contexts = result.contexts or []
print(f"Found {len(contexts)} relevant chunks")
# Output: Found 1 relevant chunks

print(contexts[0].content)
# Output: "Our refund policy: We offer a 30-day money back guarantee..."

Understanding similarity_threshold

Value	Meaning	When to Use
`0.5`	Somewhat relevant	Exploratory searches, broad topics
`0.7`	Relevant	Start here - good balance
`0.9`	Very relevant	Precise matches, technical queries

Tip: Start at 0.7, lower to 0.5 if you get no results, raise to 0.9 if results are too broad.

Step 5: Feed Context to Your LLM

import OpenAI from 'openai';

const openai = new OpenAI();

const prompt = contexts?.length 
  ? `Context:\n${contexts.map(c => c.content).join('\n\n')}\n\nQuestion: ${userQuestion}`
  : userQuestion;

const response = await openai.chat.completions.create({
  model: "gpt-4",
  messages: [{ role: "user", content: prompt }]
});

console.log(response.choices[0].message.content);
// Output: "We offer a 30-day money back guarantee. To request a refund, contact support@example.com."

import openai

if contexts:
  context_text = "\n\n".join([ctx.content for ctx in contexts])
  prompt = f"Context:\n{context_text}\n\nQuestion: {user_question}"
else:
  prompt = user_question

response = openai.chat.completions.create(
  model="gpt-4",
  messages=[{"role": "user", "content": prompt}]
)

print(response.choices[0].message.content)
# Output: "We offer a 30-day money back guarantee. To request a refund, contact support@example.com."

Result: Your AI now answers from YOUR data, not generic training data.

Complete Working Example

TypeScript
Python

import AlchemystAI from '@alchemystai/sdk';
import OpenAI from 'openai';

const alchemyst = new AlchemystAI({
  apiKey: process.env.ALCHEMYST_AI_API_KEY,
});

const openai = new OpenAI();

async function main() {
  // 1. Store document
  await alchemyst.v1.context.add({
    documents: [{
      content: "Our refund policy: We offer a 30-day money back guarantee. Contact support@example.com to request a refund."
    }],
    context_type: 'resource',
    source: 'docs',
    scope: 'internal'
  });
  console.log("✅ Document stored");

  // 2. Search for context
  const userQuestion = "What's your refund policy?";
  const { contexts } = await alchemyst.v1.context.search({
    query: userQuestion,
    similarity_threshold: 0.7,
    scope: 'internal'
  });
  console.log(`Found ${contexts?.length} relevant chunks`);

  // 3. Generate answer with context
  const prompt = contexts?.length
    ? `Context:\n${contexts.map(c => c.content).join('\n\n')}\n\nQuestion: ${userQuestion}`
    : userQuestion;

  const response = await openai.chat.completions.create({
    model: "gpt-4",
    messages: [{ role: "user", content: prompt }]
  });

  console.log("AI Response:", response.choices[0].message.content);
}

main();

Expected Output:

✅ Document stored
Found 1 relevant chunks
AI Response: We offer a 30-day money back guarantee. To request a refund, contact support@example.com.

import os
from alchemyst_ai import AlchemystAI
import openai

alchemyst = AlchemystAI(api_key=os.environ.get("ALCHEMYST_AI_API_KEY"))

def main():
    # 1. Store document
    alchemyst.v1.context.add(
        documents=[{
            "content": "Our refund policy: We offer a 30-day money back guarantee. Contact support@example.com to request a refund."
        }],
        context_type="resource",
        source="docs",
        scope="internal"
    )
    print("✅ Document stored")

    # 2. Search for context
    user_question = "What's your refund policy?"
    result = alchemyst.v1.context.search(
        query=user_question,
        similarity_threshold=0.7,
        scope="internal"
    )

    contexts = result.contexts or []
    print(f"Found {len(contexts)} relevant chunks")

    # 3. Generate answer with context
    if contexts:
        context_text = "\n\n".join([ctx.content for ctx in contexts])
        prompt = f"Context:\n{context_text}\n\nQuestion: {user_question}"
    else:
        prompt = user_question

    response = openai.chat.completions.create(
        model="gpt-4",
        messages=[{"role": "user", "content": prompt}]
    )

    print("AI Response:", response.choices[0].message.content)

if __name__ == "__main__":
    main()

Expected Output:

✅ Document stored
Found 1 relevant chunks
AI Response: We offer a 30-day money back guarantee. To request a refund, contact support@example.com.

Next: Add Real Documents

Now that you understand the basics, let’s add real documents:

From File
From API
Multiple Files

import fs from 'fs';

const content = fs.readFileSync('./docs/policy.txt', 'utf-8');

await client.v1.context.add({
  documents: [{
    content: content,
    metadata: {
      file_name: "policy.txt",
      file_type: "text"
    }
  }],
  context_type: 'resource',
  source: 'documentation',
  scope: 'internal'
});

console.log("✅ File uploaded and indexed");

with open('./docs/policy.txt', 'r') as f:
    content = f.read()

client.v1.context.add(
    documents=[{
        "content": content,
        "metadata": {
            "file_name": "policy.txt",
            "file_type": "text"
        }
    }],
    context_type="resource",
    source="documentation",
    scope="internal"
)

print("✅ File uploaded and indexed")

const response = await fetch('https://api.example.com/docs');
const apiDocs = await response.json();

const docs = apiDocs.map(doc => ({
  content: doc.body,
  metadata: {
    file_name: doc.title,
    doc_id: doc.id
  }
}));

await client.v1.context.add({
  documents: docs,
  context_type: 'resource',
  source: 'api',
  scope: 'internal'
});

console.log(`✅ Indexed ${docs.length} documents from API`);

import requests

response = requests.get('https://api.example.com/docs')
api_docs = response.json()

docs = [{
    "content": doc["body"],
    "metadata": {
        "file_name": doc["title"],
        "doc_id": doc["id"]
    }
} for doc in api_docs]

client.v1.context.add(
    documents=docs,
    context_type="resource",
    source="api",
    scope="internal"
)

print(f"✅ Indexed {len(docs)} documents from API")

const docs = [
  {
    content: "Refund policy: We offer a 30-day money back guarantee...",
    metadata: { file_name: "refunds.md" }
  },
  {
    content: "Shipping policy: We ship worldwide within 5-7 business days...",
    metadata: { file_name: "shipping.md" }
  },
  {
    content: "Privacy policy: We collect and protect your data...",
    metadata: { file_name: "privacy.md" }
  }
];

await client.v1.context.add({
  documents: docs,
  context_type: 'resource',
  source: 'documentation',
  scope: 'internal'
});

console.log(`✅ Indexed ${docs.length} policy documents`);

docs = [
    {
        "content": "Refund policy: We offer a 30-day money back guarantee...",
        "metadata": {"file_name": "refunds.md"}
    },
    {
        "content": "Shipping policy: We ship worldwide within 5-7 business days...",
        "metadata": {"file_name": "shipping.md"}
    },
    {
        "content": "Privacy policy: We collect and protect your data...",
        "metadata": {"file_name": "privacy.md"}
    }
]

client.v1.context.add(
    documents=docs,
    context_type="resource",
    source="documentation",
    scope="internal"
)

print(f"✅ Indexed {len(docs)} policy documents")

Advanced: Organize with Metadata

Use group_name to filter searches by category:

// Store with groups
await client.v1.context.add({
  documents: [{
    content: "Refund policy: We offer a 30-day money back guarantee...",
    metadata: {
      file_name: "refund-policy.md",
      group_name: ["customer-support", "policies"]  // ← For storage
    }
  }],
  context_type: 'resource',
  source: 'documentation',
  scope: 'internal'
});

// Search within specific groups
const { contexts } = await client.v1.context.search({
  query: "refund policy",
  scope: 'internal',
  metadata: {
    groupName: ['customer-support']  // ← For search (note: camelCase)
  }
});

console.log(`Found ${contexts?.length} results in customer-support`);

# Store with groups
client.v1.context.add(
    documents=[{
        "content": "Refund policy: We offer a 30-day money back guarantee...",
        "metadata": {
            "file_name": "refund-policy.md",
            "group_name": ["customer-support", "policies"]  # ← For storage
        }
    }],
    context_type="resource",
    source="documentation",
    scope="internal"
)

# Search within specific groups
result = client.v1.context.search(
    query="refund policy",
    scope="internal",
    metadata={
        "group_name": ["customer-support"]  # ← For search (note: snake_case)
    }
)

print(f"Found {len(result.contexts or [])} results in customer-support")

Naming difference: Storage uses group_name (snake_case in metadata) but TypeScript search uses groupName (camelCase). Python uses group_name consistently. Both refer to the same field - this is due to API design conventions.

Why use groups?

Benefit	Description
Faster searches	Smaller search space = lower latency
More relevant	Only search customer-support docs, not engineering docs
Better organization	Hierarchical structure like folders
Access control	Filter by team, project, or user permissions

Example hierarchy:

group_name: ["company", "customer-support", "policies"]
group_name: ["company", "engineering", "api-docs"]
group_name: ["company", "hr", "employee-handbook"]

Troubleshooting

No results from search

Error symptoms:

contexts?.length returns 0
Empty array in search results

Common causes:

similarity_threshold is too high
Document wasn’t stored successfully
scope mismatch between add and search

Fixes:Step 1: Lower the threshold:

similarity_threshold: 0.5  // Instead of 0.9

Step 2: Verify documents were stored:

const stored = await client.v1.context.view();
console.log("Total documents:", stored.length);
console.log("Documents:", stored);

Expected output:

Total documents: 1
Documents: [{ id: "doc_123", content: "Our refund policy...", ... }]

Step 3: Check scope matches:

// Both must use the same scope
await client.v1.context.add({ scope: 'internal', ... });
await client.v1.context.search({ scope: 'internal', ... });  // ✅ Match

Too many irrelevant results

Error symptoms:

Getting documents that don’t match the query
Too many results to process efficiently

Common causes:

similarity_threshold is too low
Documents are too broad or generic
Not using group filtering

Fixes:Step 1: Raise the threshold:

similarity_threshold: 0.8  // More strict (was 0.5)

Step 2: Use group filtering:

metadata: { 
  groupName: ['customer-support']  // Narrow to specific category
}

Step 3: Add more specific metadata:

await client.v1.context.add({
  documents: [{
    content: "...",
    metadata: {
      group_name: ["support", "refunds"],  // More specific
      category: "policies",
      department: "customer-service"
    }
  }]
});

Document already exists error

Error message:

{
  "error": "Document with file_name 'policy.md' already exists",
  "code": "CONFLICT",
  "status": 409
}

Cause: Trying to add a document with duplicate file_name in metadata.Fixes:Step 1: Delete old version first:

// Delete by file name
await client.v1.context.delete({ 
  metadata: { fileName: "policy.md" } 
});

// Then add new version
await client.v1.context.add({
  documents: [{
    content: "Updated content...",
    metadata: { file_name: "policy.md" }
  }]
});

Step 2: Use versioned names:

file_name: "policy-v2.md"  // or "policy-2024-02-01.md"

Step 3: Use unique identifiers:

file_name: `policy-${Date.now()}.md`  // Timestamp
// or
file_name: `policy-${uuid()}.md`       // UUID

API authentication errors

Error message:

{
  "error": "Invalid API key",
  "code": "UNAUTHORIZED",
  "status": 401
}

Fixes:Step 1: Verify API key is set:

console.log("API Key exists:", !!process.env.ALCHEMYST_AI_API_KEY);
// Should output: API Key exists: true

Step 2: Check key format:

// Should start with "alch_" or similar prefix
console.log("Key prefix:", process.env.ALCHEMYST_AI_API_KEY?.substring(0, 5));

Step 3: Get a new key:

Visit platform.getalchemystai.com/settings
Generate a new API key
Update your .env file

Rate limit exceeded

Error message:

{
  "error": "Rate limit exceeded",
  "code": "RATE_LIMIT",
  "status": 429,
  "retry_after": 60
}

Cause: Too many requests in a short time period.Fixes:Step 1: Add retry logic:

async function searchWithRetry(query: string, retries = 3) {
  for (let i = 0; i < retries; i++) {
    try {
      return await client.v1.context.search({ query, scope: 'internal' });
    } catch (error) {
      if (error.status === 429 && i < retries - 1) {
        const waitTime = error.retry_after || 60;
        console.log(`Rate limited. Waiting ${waitTime}s...`);
        await new Promise(resolve => setTimeout(resolve, waitTime * 1000));
      } else {
        throw error;
      }
    }
  }
}

Step 2: Check your rate limits:

Free tier: 100 operations/day
Pro tier: 10,000 operations/day

Step 3: Upgrade your plan: View pricing

Best Practices

Document Organization

// ✅ Good - organized with meaningful metadata
await client.v1.context.add({
  documents: [{
    content: "...",
    metadata: {
      file_name: "refund-policy-2024-02.md",
      group_name: ["customer-support", "policies"],
      department: "support",
      last_updated: "2024-02-01"
    }
  }]
});

// ❌ Bad - minimal metadata, hard to search
await client.v1.context.add({
  documents: [{
    content: "..."
  }]
});

Chunk Size Considerations

Small documents (under 1000 words): Add as-is
Medium documents (1000-5000 words): Let Alchemyst auto-chunk
Large documents (over 5000 words): Consider splitting by section

// For large documents, split manually for better control
const sections = [
  { title: "Introduction", content: "..." },
  { title: "Features", content: "..." },
  { title: "Pricing", content: "..." }
];

const docs = sections.map(section => ({
  content: section.content,
  metadata: {
    file_name: "product-docs.md",
    section: section.title
  }
}));

await client.v1.context.add({ documents: docs });

Search Optimization

// ✅ Good - specific query with filtering
const { contexts } = await client.v1.context.search({
  query: "How to request a refund for damaged items",
  scope: 'internal',
  similarity_threshold: 0.7,
  metadata: {
    groupName: ['customer-support', 'refunds']
  }
});

// ❌ Bad - too broad, no filtering
const { contexts } = await client.v1.context.search({
  query: "help",
  scope: 'internal'
});

Error Handling

async function safeSearch(query: string) {
  try {
    const { contexts } = await client.v1.context.search({
      query,
      scope: 'internal',
      similarity_threshold: 0.7
    });
    
    if (!contexts || contexts.length === 0) {
      console.log("No results found. Try a broader query.");
      return null;
    }
    
    return contexts;
  } catch (error) {
    console.error("Search failed:", error.message);
    // Fallback or retry logic here
    return null;
  }
}

Verify Your Setup

After implementing context search, verify everything is working:

Check Platform UI

Visit platform.getalchemystai.com/context
You should see your stored documents
Click to view chunks and embeddings
Check document count matches what you uploaded

Test with Code

// Test the complete flow
async function testSetup() {
  // 1. Store a test document
  console.log("Step 1: Storing test document...");
  await client.v1.context.add({
    documents: [{
      content: "Test document: The answer is 42",
      metadata: { file_name: "test.txt" }
    }],
    scope: 'internal'
  });
  
  // 2. Search for it
  console.log("Step 2: Searching for test document...");
  const { contexts } = await client.v1.context.search({
    query: "What is the answer?",
    scope: 'internal',
    similarity_threshold: 0.5
  });
  
  // 3. Verify results
  const found = contexts?.some(c => c.content.includes("42"));
  console.log("✅ Test passed:", found);
  
  // 4. Cleanup
  console.log("Step 3: Cleaning up...");
  await client.v1.context.delete({
    metadata: { fileName: "test.txt" }
  });
}

testSetup();

Expected Output:

Step 1: Storing test document...
Step 2: Searching for test document...
✅ Test passed: true
Step 3: Cleaning up...
