Atlas keeps your story and everything behind it in one place. Write chapters beside character sheets, build your world’s lore and maps, and keep every source you’ve gathered one click away from the page you’re writing. A native app for Mac, iPad, and iPhone. BUILD YOUR PROJECT HOW YOU THINK Nest documents to any depth. Any document can hold its own children, so a character can carry their backstory and a chapter can carry its research. Type [[ to link anything; links survive renames, and backlinks show every place a character or location appears. Hierarchical tags, synopses, custom fields like POV or status, and templates keep hundreds of documents easy to navigate. MAP IT ON AN INFINITE CANVAS Lay out documents, folders, images, sketches, and web pages, then drop pins to build a map of your world. Draw labeled connections between characters, plot threads, and places, gather them into groups, and edit any document right on its card. Add sketches created with Apple Pencil on iPad. KEEP RESEARCH CLOSE The Web Clipper turns articles into clean Markdown with their images and source details, and pulls full transcripts from YouTube videos. Snap a photo on your iPhone, share from any app, and keep PDFs, audio, video, and live web pages inside the project, right next to the draft that needs them. WRITE WITH FOCUS Markdown formats as you type and stays out of sight until you need it. Focus Mode dims everything but the sentence you’re on, and Typewriter Scrolling keeps your eyes in one place. Add footnotes, annotations, and tables, and check grammar privately on device with Apple Intelligence. PUBLISH ON YOUR TERMS Export ePub books with custom chapter breaks, print-ready PDFs including a 5x8” trade paperback layout with mirrored margins and running heads, HTML, RTF, plain text, or Markdown. A live preview shows exactly what you’ll get, and the built-in style editor lets you design your own look. SYNC WITH A SAFETY NET iCloud keeps your Mac, iPad, and iPhone in step. Every save creates a version you can browse, star, and restore across all devices. Edits made on two devices to different paragraphs merge automatically, and if they truly collide, Atlas helps you merge both versions so nothing is lost. YOUR WORK STAYS YOURS Documents are Markdown, canvases use an open format, and sync runs through your own iCloud account, not our servers. Whatever happens with your purchase, you can always open, edit, and export everything you’ve made. PRICING Start free with one project with a limited number of documents.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Prism Notes sells 2 one-off in-app purchases and Atlas sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.9 for Prism Notes against 5.0 for Atlas. That said, the two scores are not equally well evidenced: Prism Notes has 38 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 100% of Prism Notes's written reviews are positive against 83% of Atlas's.
Prism Notes ships an update every 3 days, Atlas every 5 days. The most recent releases landed on October 28, 2026 and October 30, 2026 respectively.
