The quiet return of local-first software
For fifteen years the default answer was the server. Your documents lived somewhere else, your edits were round trips, and an aeroplane was enough to make the tool useless.
Local-first inverts that. The device holds the real copy; the network is a synchroniser, not a landlord. Conflict-free replicated data types made the merge tractable, and cheap local storage made the rest obvious.
AI Summary
inkandatoms.comFor fifteen years software defaulted to the server — documents lived remotely and every edit was a round trip.
Local-first inverts the relationship: the device holds the authoritative copy and the network merely synchronises it.
CRDTs made conflict-free merging practical, while cheap local storage removed the last reason to centralise.
The tradeoff moves to sync infrastructure: teams own the merge semantics they used to rent from a database.
The pattern pays off where offline use is a real requirement, not an aesthetic one.

Chatbots make you bring the screen to them. Arc is already on it.
Arc: AI Screen Assistant is an AI assistant app that runs on the screen you are already looking at. On Android it's a floating sidebar over every app; on Mac and Windows it's a panel you open with Control+Space (Ctrl+Space on Windows) over any window. It reads the current screen and acts on it: summarize, read aloud, rewrite, chat, extract.
You don't describe your situation to it, because it already has the screen. It's free on Android, Mac and Windows with 7 requests a week; iPhone is in development.

With Arc
One assistant for everything on your screen.
Pick what you need done. Arc does it on the page, message or document you're already in.
Get the point of anything in seconds.
Arc turns articles, PDFs, long emails and threads into numbered key points, then answers follow-up questions about the same screen, so you never have to re-explain the context.
- Numbered key points with an auto-detected title and source
- Ask follow-ups about the page you're on
- Explain or translate in 10+ languages

Write better, right inside the text box.
Rewrite in any tone, fix grammar, draft a reply or turn notes into a post. Insert drops the result back into the field you were typing in: Gmail, WhatsApp, Slack or anything else.
- Rewrite, reply, fix grammar or create a post
- Inserts in place, with no copy-paste
- Works in every app with a text field

Hear any screen, read aloud.
Natural text-to-speech with automatic language detection. Listen to articles, documents and messages while you commute, cook or rest your eyes, straight from the floating sidebar.
- Natural voices with automatic language detection

Pull out the dates, contacts and codes.
Smart Extract reads the screen and hands back the structured bits: meeting times, addresses, phone numbers, tracking codes. Each one is ready to copy or act on.
- Dates, contacts, links and codes in one pass
- Nothing to select or highlight first
- Copy each item with a single tap

Arc works with virtually any app. However, it automatically disables itself in nearly 400 sensitive apps (banking, crypto, password managers) by default.
