Local-first

Local-first means your durable records live as files on a machine you own and can move, while AI tools and cloud services read from or sync to copies of them rather than holding the original.

Local-first means your durable records live as files on a machine you own and can move, while AI tools and cloud services read from or sync to copies of them rather than holding the original. The authoritative copy sits with you, and any service that touches it works against a sync of that source. Picture a folder of plain-text notes and labeled records on your own drive. An assistant reads that folder to draft a daily brief, a backup service mirrors it, and a phone app syncs a copy for quick edits, but the version on your drive stays the master. If a tool shuts down or changes its terms, you still hold the files and can point a different assistant at the same folder.

Builder example

If you build a knowledge system on top of one vendor's storage, your records are only as durable as that vendor's pricing and uptime. Keeping the original as portable files on your own machine means an outage, a price hike, or a discontinued product does not strand your notes, decisions, and contacts. A morning-brief assistant can read the same local folder today and after you switch tools, so the workflow survives the tool that happened to run it.

Common confusion: Local-first does not mean offline-only or a refusal to use the cloud. You can still sync to other devices and let cloud assistants read your material; what stays local is the authoritative original, so syncs and services are copies you can disconnect without losing the source.
