Best 67 AI Knowledge Graph Tools in 2026

Alma is a cognitive memory and identity engine for AI conversations. Instead of starting every chat from scratch, Alma automatically extracts facts (Memories), conversation summaries (Episodes), and learned behavioral patterns (Procedures) from your conversations. A 12-block Soul Engine defines your AI's identity — worldview, communication style, anti-patterns, and behavioral boundaries — and assembles personalized context for every conversation in milliseconds. Three memory types: semantic facts scored by importance and confidence, conversation episode summaries tagged with topics and outcomes, and behavioral procedures learned automatically. Hybrid search combines keyword matching with semantic embeddings for precise recall. Available as web app, MCP server (21 tools, 9 resources for Claude Desktop/Cursor/Windsurf), VSCode extension, and full REST API (200+ endpoints). Powered by Anthropic Claude (3 models). 15 languages. BYOK support. AES-256-GCM encryption. TOTP 2FA. OAuth (Google + GitHub). Full GDPR data export and deletion. Free tier: 500 memories, 50 episodes, Claude Haiku — no credit card, no time limit. Pro $19/mo. Advanced $49/mo. Ultimate $149/mo.

Upgrade when you need more memory and power. Product Overview The Complete Memory Layer for AI Alma is a persistent memory system that transforms stateless AI into a genuine collaborator. It captures facts, summarizes conversations, and learns behavioral patterns — building a cognitive profile that grows with every interaction. Your AI stops forgetting and starts understanding. 3-Layer Memory Architecture Memories facts, preferences, decisions Episodes summaries, context, threads Procedures patterns, triggers, workflows. 01 — Architecture Three layers of understanding Alma's memory system mirrors how humans process and retain information — through facts, experiences, and learned behaviors. 1 Memories Discrete facts about the user — preferences, decisions, technical context, personal details. Each memory is semantically indexed and retrievable by relevance. User prefers TypeScript over JavaScript Project uses PostgreSQL 16 Prefers concise explanations 2 Episodes Compressed summaries of conversations and interactions. Episodes capture the arc of a discussion — what was decided, what changed, what matters. Debugged auth middleware issue Designed new database schema Reviewed API architecture decisions 3 Procedures Learned behavioral patterns and workflows. Procedures define when and how the AI should act — from communication style to complex multi-step processes. When reviewing code, check error handling first Use bullet points for technical explanations Always suggest tests for new functions Soul Engine & Context Assembly All three layers feed into the Soul Engine, which assembles the optimal context for every interaction. It selects the most relevant memories, recent episodes, and applicable procedures — then renders them into a structured system prompt that gives the AI deep understanding of who you are and what you need. 02 — Capabilities Everything you need for persistent AI A complete platform for building AI that remembers, learns, and adapts to every user. Persistent Memory Every fact, preference, and decision is stored and recalled across sessions. No more repeating yourself. The AI remembers what matters to you. Context Assembly Automatically builds the right context for every conversation. Relevant memories, recent episodes, and learned procedures — assembled in milliseconds. Soul Engine v2 A complete cognitive framework that defines how the AI thinks, responds, and grows. Personality, guidelines, and behavioral patterns — all configurable. Multi-Model Support 3 intelligence tiers powered exclusively by Anthropic's Claude models. Free plans include Normal (Claude Haiku). Paid plans add Advanced (Claude Sonnet) and Complex (Claude Opus). Switch freely without losing context or memory continuity. Multi-Modal Dedicated Image Studio with Flux Pro and Leonardo AI. Voice chat with speech-to-text and text-to-speech. File uploads with AI vision analysis. Document generation (DOCX, XLSX, PPTX). All with persistent memory. Background Processing Learns while you chat. Memories are extracted, episodes are summarized, and procedures are refined — all happening seamlessly in the background. 03 — Technical How it works Four steps from zero to a fully memory-aware AI. Integrate in minutes, not weeks. 1 Connect Generate an API key in your dashboard settings. # Generate an API key in Settings → API Keys # Then authenticate with Bearer token curl https://alma.olivares.ai/api/v1/me \ -H "Authorization: Bearer YOUR_API_KEY" 2 Assemble Context Build the perfect context for any conversation with a single API call. # Assemble relevant context for any query curl -X POST https://alma.olivares.ai/api/v1/context/assemble \ -H "Authorization: Bearer YOUR_API_KEY" \ -d '{ "query": "Help me refactor the auth module" }' # Returns: memories, episodes, procedures # ranked by semantic relevance 3 Chat with Memory Send messages through Alma and get responses enriched with full memory context. # Send a message with full memory context curl -X POST https://alma.olivares.ai/api/v1/chat \ -H "Authorization: Bearer YOUR_API_KEY" \ -d '{ "message": "What approach should we take?", "model": "claude-sonnet" }' # The AI knows your preferences, your project # context, and your history. 4 Background Learning After each conversation, Alma automatically extracts and stores new knowledge. # This happens automatically after each chat: # 1. New facts are extracted as memories # → "User decided to use JWT for auth" # 2. The conversation is summarized as an episode # → "Discussed auth refactoring approach" # 3. Behavioral patterns are updated # → "When discussing architecture, provide # trade-offs and alternatives" 04 — Platform Integrate everywhere Alma meets you where you work.
