Ariv - Notes, PKM Second Brain

A local-first second brain with notes, tasks, voice memos, visual maps, calendar, and AI built in. Think freely. No setup required.

Ariv is a local-first second brain for notes, tasks, journaling, study, projects, and personal knowledge management.

Capture ideas, organize work, search your vault, ask questions about your notes, and keep your thinking connected without building a complicated plugin setup.

Everything is built in:

• Markdown notes and daily writing
• Smart dashboard for active work
• Tasks and Kanban
• Quick capture
• Voice memos with transcription
• Ask Brain, an AI assistant for your notes
• Calendar-aware planning and meeting context
• Graph view and visual maps
• Templates and presentation mode
• Unified search across files, tags, and content

Ariv is designed around a simple idea: your notes have a life.

New thoughts land in your inbox. Active notes stay visible while you are working on them. Older notes move out of the way but stay searchable, linkable, and ready to resurface when you need them.

No manual filing system required. No weekend spent setting up plugins. Open the app and start thinking.

Your files stay yours:

• Notes are stored as plain Markdown
• Works with existing Markdown folders and vaults
• No proprietary format
• No account required to use the local app
• Optional end-to-end encrypted sync is available

AI is optional and on your terms. Use your own API key, run supported local models, or use Ariv's managed AI add-on. Ask Brain can answer questions from your vault and point back to the notes it used.

Whether you are a student, writer, researcher, developer, founder, or lifelong learner, Ariv gives you one place to capture, connect, and use what you know.

Think freely. No setup required.
