Write, think, and build with Aristra — and every session makes your AI sharper. Not a chatbot. Not a note-taking app. A cognitive layer that compounds the longer you use it.

AI tools today are powerful but amnesiac. ChatGPT remembers your name. That's not knowing you. Aristra builds a model of how you actually think — and it gets sharper every day.
Finds similar text. Doesn't understand relationships, contradictions, or how your thinking has evolved.
Stores facts like "prefers bullet points." Resets or bloats. No sense of what matters most right now.
Maps how ideas connect. Your pivot last quarter changes how it thinks about your roadmap today. That connection gets made.
Context that stays sharp. Old irrelevant memories fade. What matters surfaces. Your AI never drowns in its own history.
Self-updating context that learns from every interaction. Not a list of facts — a living map of relationships. The pivot you made last quarter changes how Aristra interprets what you're building today. That connection gets made.
Relational reasoningDocs, conversations, notes, code, voice memos — Aristra ingests it all and maps meaning, not just keywords. It finds the connections your other tools miss, then surfaces them when they actually matter.
Multimodal ingestionAs memory compounds, most systems collapse under their own weight. Aristra's decay mechanism surfaces what matters and retires what doesn't — so your agents always have the right context, never the full archive. Sharp by design.
Decay algorithmUse Aristra like Notion — write docs, upload files, work how you normally do. Everything you add builds the memory layer your agent runs on. The more you put in, the smarter it acts.
A full writing editor with AI built in. Slash commands, drag-and-drop blocks, code, tables, math — plus inline AI that writes alongside you. Your documents don't just live here. They inform how your AI thinks.
Like Notion, but smarter over timeDump everything — PDFs, voice memos, images, URLs, video. Aristra reads it, understands it, and connects it to everything else you've added. Stop copy-pasting context into every AI chat.
Any format · Semantic understandingEvery Aristra user gets a personal agent powered by Aristra's memory engine. Chat with it, assign tasks, let it run autonomously. It knows your projects, your decisions, your style — and it shows up wherever you already work.
Autonomous · Multi-platform · Always in contextYour memories aren't a list — they're a living map. See how ideas connect, watch your knowledge grow, and catch when things contradict. Your thinking, visualized.
Relational memory · VisualAristra captures context as you browse — articles you read, research you do, pages you revisit. No copy-pasting, no manual logging. Your memory grows in the background, automatically.
Ambient capture · Always onEvery Aristra user gets a personal agent powered by everything they've built in their workspace. It doesn't just answer — it acts. Autonomously, across every platform you already use.
Assign it work and step away. Your agent executes tasks, makes decisions grounded in your memory, and reports back. No babysitting required.
Slack, WhatsApp, Claude, ChatGPT, your own interface — your Aristra agent is available everywhere via MCP. Same memory, every platform.
Every task it runs is informed by your full cognitive layer — not just what you typed in the last message. It knows your history, your preferences, your context right now.
Routes to the best model for each task — Claude, GPT-4, Gemini and more. You get the output. Aristra handles the infrastructure.
Aristra is designed to compound. Every interaction makes the next one better — for you and for every agent you connect.
Write docs, upload files, have conversations. Use it like any workspace — Aristra works in the background to map meaning and relationships.
→Every session builds your cognitive layer. Aristra understands more about how you think, what you're working on, and what matters most right now.
→Your agents — Claude, ChatGPT, your own — tap into this memory via MCP. They stop starting from zero. They stop hallucinating your context.
Consumer users build the memory layer. Developers plug into it. Connect any agent to your Aristra workspace via MCP or REST API — and give it the context it actually needs to behave correctly.
One config block. Claude, ChatGPT, any MCP-compatible agent instantly reads your memory layer. No SDK, no code.
Create memories, run semantic search, manage decay policies, trigger agents. Build Aristra into your own products.
