Tesslate is a superintelligent knowledge API that helps developers and AI agents build faster with graduated autonomy levels—from simple search to complex planning.
# Ask Tesslate anything about code
import tesslate
# Level 2: Get an intelligent answer
response = tesslate.answer(
question="How to implement OAuth in Next.js 14?",
context={"stack": ["PostgreSQL", "Prisma"]}
)
# Level 6: Full autonomous planning
plan = tesslate.plan(
goal="Build a real-time collaborative editor",
constraints={"timeline": "3 months", "team": 2}

import tesslate from '@tesslate/sdk';
const client = new tesslate.Client({
apiKey: process.env.TESSLATE_API_KEY
});
// Simple search (Level 0)
const results = await client.search({
query: 'React hooks best practices',
limit: 10
});
// Get an answer (Level 2)
const answer = await client.answer({
question: 'How to handle errors in async React components?',
context: { framework: 'react', version: '18' }
});All API requests require authentication via Bearer token.
Tesslate provides graduated autonomy levels through different endpoints.
Fast, direct search across indexed knowledge.

}We're on a mission to make software development faster, smarter, and more accessible through cognitive infrastructure.
Our Mission
We believe that access to accurate, up-to-date technical knowledge shouldn't be a bottleneck in software development.
Tesslate serves as the cognitive backend for both human developers seeking instant answers and AI agents that need reliable knowledge to build software autonomously.
Our Journey
Started building the core RAG engine and knowledge ingestion pipeline.
Released private alpha with 100 developers testing core endpoints.
Opened beta access, raised seed funding to scale infrastructure.
Opening early access to the public. Join us in building the future!
