tl;dr — Local-first macOS app. Markdown notes + EPUB + media + AI chat, all offline-capable. PolyForm Noncommercial 1.0, macOS 14+.
Local-first notes, ebooks, and media — with AI that can run fully on-device
Open-source macOS app for Markdown notes, EPUB reading, and media playback. Three on-disk roots (Notes / Media / Ebooks), multi-provider AI (on-device MLX + remote OpenAI-compatible + Google Gemini), optional YouTube downloads via yt-dlp. No account, no telemetry.
Four pillars in one app — each backed by a plain folder on disk
Plain .md files on disk, folder tree sidebar, split preview, tabs, search, focus mode, per-note chat, dashboard, daily digest.
Inline .epub reader with TOC, click-edge page turn, highlights, fonts, themes. Ebooks folder auto-scanned.
Music + video auto-scanned from Media root. AmbientPlayer for audio, inline MediaPlayerView for video.
Polish / summarize / translate / grammar / continue writing. Swap providers in Settings — MLX on-device, Ollama / vLLM / LM Studio, or Google Gemini with free-tier key rotation.
Every note has its own chat session scoped to that note's context. Switch note — switch chat.
[[Note]] syntax renders as clickable pills in the preview. Status-bar pill lists every note that links back, auto-rebuilt in the background.
Fuzzy-find across the whole vault. Recent files first, exact / prefix / contains / subsequence scoring. Open Recent submenu keeps the last 30 across launches.
Inline #tag and YAML frontmatter tags are indexed vault-wide. Workflow > Browse Tags... opens a two-pane browser keyed by tag.
Streaming 3-5 bullet summary of the active note. Uses the same provider stack as inline AI tools.
Paste a URL, yt-dlp downloads to the Media folder (mp3 / mp4). ffmpeg unlocks mp3 + ≥1080p.
No account — open the app, pick three folders, start writing.
No telemetry — nothing leaves the device unless you wire a remote AI provider.
Plain files on disk — notes are .md, ebooks are .epub, media is whatever you drop in. Zero lock-in.
On-device AI — MLX runs Apple-Silicon models locally. No network round-trip, no API bill.
For contributors. End users: grab the .dmg from Releases.
brew install xcodegengit clone https://github.com/NextAgentBC/NextNote.gitcd NextNote && make buildmake runNextNote is source-available under PolyForm Noncommercial 1.0 and actively developed. Issues, PRs, and forks welcome.
No. Notes are plain .md files on your disk. The only time data leaves the machine is if you choose a remote AI provider (Gemini or a remote OpenAI-compatible endpoint) — and only the text you pass into that AI feature.
No account, no subscription. MLX on-device AI is free. Gemini free tier works out of the box with key rotation. Bring your own keys for anything else.
Not currently planned. NextNote is a native SwiftUI + SwiftData app and depends on Apple frameworks. macOS 14+ only.
Yes — it's source-available under PolyForm Noncommercial 1.0 (free for personal/research/nonprofit use; commercial use needs a separate license). TUTORIAL.md walks through the architecture, and the test target is deliberately open for contributors. Issues and PRs on GitHub.
