Memory

Atlas remembers everything in your vault

Every conversation is journaled as Markdown. BM25 retrieval pulls the relevant notes into each turn, and Atlas auto-links what it writes back into a real wikilink graph — no separate database to manage.

Action

When you need something done, Atlas acts

Every capability is an MCP server — Atlas can search the web, write files, message you on WhatsApp, or scaffold a brand-new tool when nothing else fits. Every action lands in a full audit log.

Frequently asked questions

Is the browser preview full Atlas? No — see what's simulated →
Does my data leave my machine?+
Not with a local model backend like Ollama or LM Studio — everything, including speech-to-text, runs locally. Using a hosted API means only the relevant text is sent to that provider.
Do I need Obsidian?+
No — the vault is just a folder of Markdown files. Obsidian is a nice way to browse and edit it, but entirely optional.
What happens if a model provider goes down?+
Atlas fails over to the next tier in your configured Model Hierarchy mid-message, and tells you it switched.
Is WhatsApp required?+
No, it's on by default during setup but fully skippable, and re-run setup anytime to add it later.
