Cognitive Memory
for Any Ai System

Autonomous robots. Self-driving vehicles. Defense systems. Coding assistants. Personal Ai companions. Any Ai system that needs to remember. CogmemAi gives your Ai persistent recall across sessions, devices, users, and teams — and captures knowledge autonomously, even when your Ai forgets to save.

Cognitive Memory — personalize your Ai companion
Your Ai learns and adapts to you — just tell it what you want, no settings pages needed

Ai Systems Have No Memory

Every session starts from zero. Every operator re-explains. Every asset forgets what it learned.

Amnesia After Every Session

Ai assistants, autonomous systems, and agents start fresh every time. Weeks of context, decisions, and learned patterns — gone.

Knowledge Walks Out the Door

When engineers retire, operators rotate, or assets are replaced — institutional knowledge disappears. The next person starts from scratch.

Locked Into One System

Switch tools, switch models, switch machines — start over. Memory doesn't travel. CogmemAi is portable across any Ai system.

CogmemAi Fixes All of This

Add persistent Cognitive Memory to any Ai system — from personal assistants to autonomous fleets. CogmemAi captures knowledge automatically, even when your Ai forgets to save.

Cognitive Memory

Your Ai learns your name, preferences, family, goals, and history — and understands them by meaning. Say "how's my kid?" and it recalls your daughter plays soccer, even if you never used those exact words.

Custom Personalities

Make your Ai a professional assistant, casual friend, study buddy, life coach — or create your own personality from scratch.

Reminders & Tasks

Ask your Ai to remind you about meetings, birthdays, or deadlines. Get email reminders and a daily digest of what's ahead.

Any Provider, One Cognitive Memory

Use OpenAI, Anthropic, or Google — your memories travel with you. Switch providers without losing a thing.

File Uploads

Upload images, PDFs, Word docs, spreadsheets, and more. Your Ai analyzes them instantly — up to 10MB per file.

Choose Your Ai Model

Pick the exact model you want — GPT-4.1, Claude Sonnet 4.5, Gemini 2.5 Pro, and more. Your API key, your choice.

Voice Input

Tap the mic and talk naturally. Your words are transcribed instantly — perfect for hands-free chatting on the go.

Not Just Memory. Intelligent Memory.

95.10% on LongMemEval — top published score on the field’s hardest long-term memory benchmark. 91% on LoCoMo, above human performance. Most Ai memory is a text file that gets bigger until it breaks. CogmemAi is a multi-layer intelligence system that gets smarter the more you use it.

Structured Recall

Memories are categorized — identity, relationships, preferences, events, emotions — and ranked by importance. The right facts surface at the right time.

Importance Decay

Fresh, frequently-referenced memories stay strong. Old, trivial details fade naturally — just like human memory. No clutter, no bloat.

Semantic Understanding

Your Ai finds memories by meaning, not keywords. Ask about "my pet" and it recalls your golden retriever Max — even if you never said "pet" before.

Precision Reranking

Every recall runs a second-pass reranker that re-scores all candidates for precision. The most relevant memory always surfaces first — not just the closest match.
