100+ Models

Continuously expanding, each Gateway independently configurable

Vecstruct Core Features

One platform for AI model access, knowledge base queries, and AI memory — from personal productivity to team collaboration, scale as you need.

AI Gateway Unified Access

One API Key for 100+ AI models, 100% compatible with OpenAI SDK. Auto-switches to a backup model when the primary is unavailable, with rate limiting and request caching.

RAG Knowledge Base

Upload documents to build your AI knowledge base. AI answers questions from your own data, with source citations and relevance scores on every answer to reduce hallucinations.

Agent Memory

Give AI persistent memory across conversations. Remembers user preferences and interaction history. Memory survives after sessions end — building a truly personalized AI.

OpenAI API Compatible

Just replace base_url — no code changes needed. Works with Python, Node.js, Go, and all OpenAI SDKs.

Audit Log

Every AI interaction fully recorded — track token usage (AI call costs) and cost breakdowns. Business plans support report export and tamper-proof audit chains.

Budget Control & Alerts

Set monthly budget caps with alert notifications. Track token consumption and costs for each Gateway in real-time.

One platform, complete AI capabilities.

From AI model access to knowledge base queries to cross-session memory — current features available now, more capabilities continuously expanding.

AI Gateway

Available now

One API Key for 100+ AI models, fully compatible with OpenAI format. Swap base_url, zero code changes; multi-Gateway configs, automatic fallback, request caching. Pay as you go, no subscription required.

Knowledge Base

Plan required

Upload PDFs, documents, notes — AI instantly answers questions from your data. Every answer includes source citations (which file, which passage) so you can verify directly. No more AI hallucinations.

AI Memory

Plan required

Let AI remember each user's preferences and interaction history. Memory persists after conversations end — pick up right where you left off. Build a truly personalized AI experience.

How exactly do you apply the Feynman Technique step by step?

Based on Personal Learning Notes.pdf Chapter 2

The Feynman Technique has 4 steps: 1. Pick a topic and write it out in the simplest language from scratch; 2. Find where you get stuck and can't explain clearly; 3. Go back to the source material to fill in those gaps; 4. Use analogies to make the concept even simpler. Core principle: if you can't explain it in plain language, you don't truly understand it yet.

...every place where your explanation gets stuck is exactly where your understanding is incomplete. Filling those gaps is what real learning looks like...
