Build a StackEdit-style markdown editor. Split-pane layout with a monospace editor on the left and a live HTML preview on the right. Toolbar with bold / italic / heading / link / list / quote / code buttons + ⌘B / ⌘I / ⌘K shortcuts. Multi-doc sidebar where the title follows the first heading the user types. Autosave to localStorage every 400ms. Export current doc as a slugified .md file.

Create a distraction-free writer's workspace like IA Writer. Single-pane focus mode, large monospace text, sentence-level focus mode that dims everything except the current sentence, dark theme by default, word/character/reading-time counter pinned to the footer, no UI chrome at all when typing.

Design a personal-wiki note app like Obsidian. Multi-document sidebar with nested folders, [[wiki-link]] support that turns into a real link when the target note exists (creates a new note on click otherwise), backlink panel showing every note that mentions the current one, full-text search across all notes.

Build a meeting-notes app for fast capture during calls. Single-pane editor, autocomplete for @mentions of attendees, hashtag tags that the sidebar groups notes by, /TODO / /DECISION / /BLOCKER slash-commands that insert a styled callout block, end-of-meeting 'summarise' button that calls FloopAI to extract action items.

よくある質問

How does this compare to StackEdit / Bear / Typora / Obsidian?
StackEdit is the closest functional match — both run in the browser with localStorage and a side-by-side preview. The difference is ownership: this is YOUR app on YOUR subdomain that you can refine indefinitely. Bear / Typora / Obsidian are downloadable native apps with their own file formats; FloopFloop generates a web app you can extend with whatever feature you describe next ('add tag filtering', 'add a daily-note auto-create', etc.) without touching code.
Where are my notes stored?
The default template uses browser localStorage so the editor works instantly with no signup. Notes live on whatever device you're typing on and don't sync across devices. Refine with 'add a Postgres backend so notes sync across devices via a login' to move to server storage — the codegen scaffolds the schema, the API routes, and the sync logic in one round. The scanner blocks every external database (Supabase / Firebase / MongoDB) so the data stays on your own per-tenant Postgres schema.
Is the rendered preview safe from XSS?
The default template renders markdown through `marked` and injects the result with dangerouslySetInnerHTML. That's safe for a single-user localStorage editor because the markdown source IS the user — you can't XSS yourself. The src/lib/markdown.ts file explicitly warns operators to add DOMPurify before extending to multi-user / shared notes (anywhere a hostile collaborator's markdown could reach another user's browser).
What markdown flavor is supported?
GitHub Flavored Markdown (GFM): tables, autolinks, line breaks, fenced code blocks, lists, blockquotes, strikethrough, task lists, headings, images. Refine with 'add KaTeX rendering for $...$ math expressions' or 'add Mermaid rendering for ```mermaid code blocks' to extend — the codegen wires the parser and the preview CSS in one round.
Can I share a note with someone?
Not in the localStorage default — notes are per-device. For sharing refine with 'add a per-note share URL that anyone with the link can read; show a read-only rendered view at /share/[id]'. The codegen generates the route, the per-note share token, and the read-only renderer. Public-write sharing (anyone with the link can edit) follows the same pattern with a separate token tier.
Does it work offline?
Reads/writes work offline because everything is localStorage — there's no network call after the initial page load. Refine with 'add a service-worker that caches the app shell so I can open the page with no connection at all' to add full PWA offline support; the codegen scaffolds the manifest and the cache-first service worker in one round.
Can I export all my notes at once?
The default exports the active document as a single .md file. For bulk export refine with 'add an Export All button that bundles every note as a .zip of .md files'. The codegen wires the JSZip dependency and the download flow. Markdown-to-PDF / -DOCX is the same shape (`add an Export as PDF using @react-pdf/renderer`).
