How BrainUs AI differs from other educational AI APIs
Overview
BrainUs AI is built specifically for developers who need reliable, citation-backed educational content. Unlike other solutions that use simple API proxies or manual PDF selection, BrainUs uses advanced RAG (Retrieval-Augmented Generation) technology to provide accurate, curriculum-aligned responses.
Apilage AI
Apilage AI offers an API for educational chatbots, but with several limitations compared to BrainUs.
Architecture Differences
Apilage AI: Uses direct Gemini API calls without true fine-tuning or RAG. Responses lack verifiable citations and curriculum alignment.
BrainUs AI: Purpose-built RAG system with 1000+ indexed curriculum documents. Every response includes verified citations with page numbers.
Feature Comparison
| Feature | BrainUs AI | Apilage AI |
|---|---|---|
| API Access | All plans (Free starts at LKR 0) | Power User plan (Rs. 1000) |
| Architecture | RAG with document retrieval | Direct LLM API proxy |
| Citations | Yes, with page numbers | No |
| Token Pricing | 300 requests/month (Free) | 150,000 tokens (60 days) |
| Validity | Monthly recurring | 60 days expiry |
| Rate Limits | 10/min (Free), 60/min (Pro) | Not documented |
| Documentation | Comprehensive with SDKs | Basic cURL example |
| SDKs | Python, JavaScript/TypeScript | None |
| Curriculum Alignment | Verified Sri Lankan curriculum | Generic responses |
| Language Support | Sinhala, English, Tamil | Sinhala, English |
| Free Tier | Yes (300 requests) | No |
| Filters | Grade, subject, document filters | Not available |
| Response Quality | Citation-backed, verified | Unverified LLM output |
Why Choose BrainUs?
Better Architecture: RAG ensures responses are grounded in actual curriculum documents, not generic LLM knowledge.
Transparent Pricing: Clear monthly limits with no token counting confusion. Free tier available.
Developer Experience: Official SDKs, comprehensive docs, code examples, and full API reference.
Educational Focus: Purpose-built for Sri Lankan curriculum with verified content sources.
Apilage AI's "150,000 tokens" translates to roughly 112,500 words or ~5,000 requests. BrainUs Free tier offers 300 requests with predictable limits.
Apola AI
Apola AI is a chat interface without a public API. Their approach requires manual grade/subject selection before each conversation.
Architecture Differences
Apola AI: Uses a manual PDF selection mechanism. When you select grade/subject, it loads the relevant PDF and sends chunks with each query. No true AI-powered retrieval.
BrainUs AI: Intelligent RAG system that automatically retrieves relevant content across all documents without manual selection. Smart filtering and semantic search.
Feature Comparison
| Feature | BrainUs AI | Apola AI |
|---|---|---|
| API Availability | Yes, fully documented | No public API |
| Developer Access | REST API + SDKs | Web interface only |
| Content Selection | Automatic intelligent retrieval | Manual grade/subject selection |
| Multi-Document Search | Yes, searches across all docs | Single PDF per session |
| Citations | Automatic with page numbers | Manual PDF reference |
| Integration | Any application via API | Web interface only |
| Scalability | Production-ready infrastructure | Limited to web UI |
| Batch Processing | Yes | No |
| Rate Limits | Clear, documented limits | Not applicable |
| Pricing Model | Transparent per-request | Not applicable (no API) |
Why Choose BrainUs?
API-First: Built for developers to integrate into any application - mobile apps, web platforms, LMS, assessment tools.
Intelligent Retrieval: No need to manually select grade/subject. BrainUs automatically finds relevant content across all curriculum materials.
Scalable: Handle thousands of concurrent users with production-grade infrastructure.
Flexible: Use filters when you want specificity, or let the AI find the best content automatically.

"Why is BrainUs more expensive than Apilage AI's token model?"
BrainUs pricing is per-request, not per-token. This is more predictable and transparent. Our free tier (300 requests) is perfect for testing, and paid plans start at LKR 999/month for 2,000 requests.
"Can I migrate from Apilage AI?"
Yes! Migration is straightforward. We provide migration guides and support. Contact developer@brainus.lk.
"Does BrainUs support custom content?"

"What makes RAG better than direct LLM calls?"
RAG grounds responses in actual documents, providing:
- Verifiable citations
- Reduced hallucinations
- Curriculum-accurate content
- Transparent sourcing
Direct LLM calls can hallucinate facts and provide unverified information.
