Sketchbook, release by release
Sketchbook is a notebook, diary, sketchpad and scratch space in one, with mail built in. It runs in the browser and as an Android app for the tablet, the phone and the car, and it is the place where its owner and Claude work on the same pages. It was built with Claude Code, using the habits described in the guide.
- Publish now, through one gateway A Ready draft in Social can now be published straight to Instagram or LinkedIn through the platforms’ own programming interfaces. Accounts are connected with each platform’s own sign-in, Claude may publish only where a per-account switch allows it, and every attempt is written down.
- Tap a picture to see it full screen Every picture in Sketchbook now opens full screen when you tap or click it, on a black background, with zoom, the next and previous picture, and Download or Share. On the web, the tablet and the phone.
- Jump to the latest reply, and no more jumps to the top The Claude chat gets a round button that takes you straight to the newest reply, with a count of what came in while you were reading further up. And the chat no longer throws you back to the start of the conversation.
- Files and photos on the go, and a lock on memory Sketchbook can now show its owner’s own files and photos on the web, the tablet and the phone, with pinned files on the home screen. Personal and finance folders, the photos and Claude’s memory sit behind the same PIN as the private journal.
- Social, drafts of posts that show the work Sketchbook has a Social section. Claude drafts a post from a notebook page, with its photos prepared for Instagram, Facebook, LinkedIn or X, and the post goes out from the phone’s own share sheet. Sketchbook itself never publishes anything.
- Two Claude accounts, side by side Sketchbook’s Claude section now works with two Claude accounts at once. Every session says which account it runs on, and new sessions, the terminal and Ask Claude can each use either one.
- The Library moves into Sketchbook Everything in the narrated library can now be browsed, read, listened to, edited, archived and deleted inside Sketchbook, with one player that keeps going in the background, and Android Auto for the whole library.
- Mail in its own window, and notifications Mail moves out of the sidebar into a window of its own, and a bell on every screen collects alerts, reminders, new mail and Sketchbook’s own events, with phone notifications on Android.
- Five tools: Print, Reminders, Drop, Calculators and Service status Print a page on a real printer at the right paper size, manage phone reminders, share a file with a link, work out engineering numbers from cited sources, and see at a glance whether everything is answering.
- A critic loop, and every shared file saved Four rounds of independent critics found and fixed dozens of bugs and rough edges across the web, tablet and phone, and files from the file-share page are now saved into the notebook automatically.
- Manuals, a Tools page, and Ask Claude as a floating button A Manuals section filed by manufacturer, category and model; a Tools page for the things that keep being added; Claude’s memory as a readable graph; and Ask Claude floating over every page.
- Links, emailing files, and Ask Claude Web addresses become links everywhere, any file in the notebook can be emailed, other apps can share into Sketchbook’s mail, and a quick Ask Claude lives in the sidebar and on the home screen.
- Pictures inside an email Pictures placed inside a draft are shown on the compose screen and sent exactly as you saw them.
- One Inbox Mail drops the Focused and Other tabs and shows a single Inbox.
- Many photos and files at once A camera that stays open, batches of photos and files in one go, and an upload queue that shows progress, retries and survives going offline.
- The phone and tablet catch up, and a browser of their own Sending mail from the phone with a fingerprint, the journal’s quick ask and PIN on every device, a Claude terminal, and links that open in Sketchbook’s own light browser.
- Navigation, housekeeping by Claude, and a real mail client The sidebar in the owner’s own order, folders that Claude names and tidies, and mail with folders, a list and a reading pane.
- The car, the tablet, and the instrument look The whole notebook on the car screen, a tablet in landscape with three resizable panes, and a new design that looks like an engineering instrument.
- How Sketchbook started A design brief written late on 5 October, then a notebook, a web app and an Android app built over the following day.
