No. Lattice is not on the App Store yet and there is no public beta build. The waitlist is the only way in, and it exists so I can tell you the day that changes — not to reserve a licence or take a payment.

On your device, in the app’s own store, with iCloud sync between your own devices if you turn it on. The content of every note is plain markdown, and you can import a folder of .md files and export back to one — but Lattice is not a folder of loose files the way Obsidian is. If that distinction matters to you, it should: it is the difference between a database that speaks markdown and a text editor pointed at your disk.

Yes, and with named algorithms you can look up rather than a badge: AES-GCM-256 for note content, with keys derived by PBKDF2-SHA256 and held in the system Keychain. The source is LatticeCore/Crypto/LatticeCrypto.swift.

Less than the roadmap. The plumbing exists — a vault-chat endpoint, a "related notes" call, an embedding service — but the embedding service is still close to a stub and the backend that answers those calls does not run anywhere public. So in a build you could install today, the AI features would fail quietly. I would rather write that here than let you discover it.

Mac and iPhone, built from one shared core, plus an iOS share extension for capturing from other apps. There is also a browser version in this repository, but it is a separate codebase with a different feature set — so I do not claim the four platforms are equivalent, because they are not.

There is no price, and that is a statement about the product rather than a marketing tease. There is no purchase in the app, no subscription, no App Store record and therefore no price tier to publish. Naming a number now would mean naming one I cannot honour.

A folder forces one answer to "where does this belong". A wikilink lets a note belong to every context that refers to it, and the graph is what those references add up to. In practice you stop deciding where things go and start noticing what things touch.

You export the vault and you have markdown. That is the whole reason the content is markdown rather than a proprietary rich-text blob: the exit is a file format that every other tool already reads. I cannot promise I will keep building; I can promise the exit works.

Not from the app as it stands. There is no analytics SDK, no telemetry framework and no crash reporter in the codebase — you can grep for it. The one exception is the AI layer described above: a question you ask about your vault, and the note excerpts needed to answer it, would go to a server. That layer is off today because the server is not running.

Yes. VaultImporter reads a folder of .md files and creates a note per file, keeping the folder structure as paths. Wikilinks between them resolve once they are in.

The parts that are yours do: writing, linking, backlinks, the graph and search all run on your device with no network. The AI layer is the only thing that needs a server, which is also why it degrades quietly rather than blocking anything.

There is a browser build in the repository, and it has things the native apps do not — live collaborative editing and a sandboxed plugin API. It also lacks things the native apps have. I keep them listed separately for that reason.

I do not have a number I would stand behind. The graph is the part that gets slow first, and its performance work is still open in the audit. Publishing "handles 10,000 notes" without having measured it is how a benchmark becomes a support ticket.

Because the two things I wanted were never in the same app: markdown I could take with me, and links that were doing something rather than sitting there. See the note further down the page — it is one person’s answer, not a market analysis.

Not planned. The scope document for this app names three things it deliberately is not, and a collaboration suite is the shape it would drift into first.

Every email carries an unsubscribe link, and /unsubscribe takes an address directly. It answers the same way whether or not the address was on the list — otherwise the form would be a way to find out who signed up.
