Stop re-explaining yourself. Tell it once in Claude Code — it’s already there in Cursor, Codex, and every tool you connect. Automatically.


Works with your AI tools · + more coming
Close the tab and the context is gone. You re-explain your project, your preferences, and your decisions to the same tools, over and over.
The context you build in one AI tool stays trapped there. Switch to another and you start over — every tool an island, blind to the rest.
Systems that do remember tend to hoard everything — duplicates, dead tasks, facts you've long since changed — until recall is buried in noise and old answers resurface as if they were still true.
Monday, working with your AI, you settle a real decision: the launch moves to March — and the shortcut that burned you last quarter is a trap to avoid. You write nothing down. Atlaso captures both as you work — decisions, watch-outs, open questions — with secrets scrubbed before anything is stored.

Tuesday, a fresh session. Before your first prompt reaches the model, Atlaso has already recalled what matters — yesterday's launch decision, the trap you flagged, the question you left open — and placed it in context. No re-explaining, no cold starts.

Thursday, you open a different AI tool. It already knows — the decision travelled with you, because memory lives with your account, not inside any single app. Personal memory follows you everywhere; each project's memory stays cleanly isolated.

Months later, plans change — the launch moves again. Atlaso doesn't let the two versions quietly coexist: the contradiction is flagged, the outdated decision retired, and every memory graded by the evidence behind it — so your AI acts on what's settled today, never on what used to be true.


Choose where your memory should live — Claude Code, Cursor, Codex, Claude Desktop, and more.
Run the install command below and click authorize — or paste the connector URL if your tool has no terminal. About a minute — no config, no API keys to wrangle.
That's it. Atlaso captures as you work and recalls what matters before every turn — automatically, across every tool you connected. Nothing to manage.
Evidence recall on LongMemEval-S
QA accuracy, full-haystack
We test the real shipped engine on LongMemEval-S — 115k-token haystacks, all six question types, an independent judge. The numbers are strong. But a benchmark is a checkpoint, not the point. The real proof shows up in your everyday work, when the right context is just there.
Read the four-judge benchmark: Atlaso vs mem0 on LongMemEval-S
Hit@k — the right memory surfaced
LongMemEval-S · n=100 · full-haystack · judge: Claude Haiku 4.5 · reader: Qwen 3.5-9B. Headline stats measured through the shipped product path; the chart is our retrieval ablation in the research harness (55.9% → 69.2% with semantic retrieval on).
A personal memory that follows you across every tool, plus per-project memory that stays locked to its repo — no context bleeding between projects.
Start every session already oriented: where you were heading, what's new, and what's still unsettled — before you type a word.
Overnight, a background worker distills raw captures into clean, structured memories — tagged, graded, deduped — so recall keeps getting sharper.
See, search, and manage every memory in one dashboard — with a live Memory Power score, contradictions caught, and a clear next move.
Secrets scrubbed before anything is saved, never trained on or sold — and you can delete any memory whenever you want.
Claude Code, Codex, and the rest started as coding tools — but people now run whole working lives through them: analysis, marketing, research, operations. Whatever you use them for, Atlaso remembers it.
Your AI remembers the codebase, the decisions, and the conventions across every tool — so it never re-learns your project from scratch.
Your models, positions, and past analysis stay in the AI you plan with — so it reasons from your real numbers, not a fresh guess each session.
Clinicians and researchers keep protocols, guidelines, and prior findings intact — privacy-first, with secrets scrubbed before anything is stored.
Case facts, precedents, and client history stay in memory — so your AI can advise the next step with the whole matter in view.
Sources, experiments, and coursework build up over time — turning every new session into a continuation, not a restart.
Every account, deal, and past conversation is remembered — so your AI walks into each one already knowing the customer.
Your memory is some of the most sensitive data you have. We treat it that way — with sensible defaults, real controls, and no fine print.
TLS everywhere, and your data is encrypted at rest by our infrastructure providers. Access tokens are stored only as hashes.
We don't train AI models on your memory or sell it. On the free plan, your memory is never sent to any LLM at all.
Secrets are scrubbed before storage, each project's memory stays isolated, and you can delete any memory — or your whole account — whenever you want.
Atlaso is a memory layer for your AI tools. Connect it once, and it automatically recalls the context that matters before each turn and captures the durable facts after — so your AI remembers your decisions, preferences, and where you left off, across every tool you use.
The tools you already use — Claude Code, Cursor, Codex, Claude Desktop, OpenCode, and Antigravity, with more on the way. Anything else that speaks MCP can connect too. Your memory is shared across all of them, so what one tool learns, the others know.
One command. Paste it into your terminal and it installs Atlaso, opens your browser to link the machine — creating your account if you don't have one — then asks which of your AI tools should share the memory and sets each one up for you. No account needed first, no config files, no API keys. Using a tool with no terminal, like Claude Desktop? Add Atlaso as a connector and authorize in the browser instead.
Built-in memory lives inside a single app, is usually a black box, and doesn't travel. Atlaso is one memory across all your tools that you can actually see, search, and manage — and every recall comes with a verdict on whether the memory is settled or contested, so your AI isn't acting on shaky context.
No. Once a tool is connected, memory works automatically in the background — recall before each turn, capture after — with no new commands. If it ever hits an error, it fails silently and your tool keeps working as normal.
Yes. Secrets are scrubbed before anything is stored, your data is encrypted in transit and at rest, and we never train AI models on your memory or sell it. On the free plan, your memory is never sent to any LLM at all. You can delete any memory — or your whole account — whenever you want.
Atlaso is free for one device and one tool. Pro is $10/month and unlocks unlimited devices and tools that all share one memory, plus Ambient Memory, background enrichment, Ask your memory, and JSON export. Build is $25/month and includes everything in Pro plus a developer memory API for your own app or hardware. No trial gimmicks — cancel anytime.
Connect Atlaso to the AI tools you already use and stop starting from zero. Free to start — no credit card required.
