Most tools help you do the work. This one keeps the context.

One local workspace for terminal, notes, and AI. Everything persists. Nothing gets lost between sessions.

"I was tired of rebuilding context every morning. So I built a workspace where terminal, notes, and AI stay together."

NotesCodex terminal with Agent Mode running autonomous tasks

The real problem

You keep losing technical context

The problem is not taking notes. The problem is that your terminal, your notes, your reasoning, and your AI live in different places. Every context switch costs you time and focus.

Without NotesCodex
  • You close a terminal and lose the commands that fixed a production bug
  • Your notes about a session live in a different app than the session itself
  • You spend 10 minutes rebuilding context every time you resume work
  • Snippets, logs, decisions, and reasoning are scattered across 5 tools
With NotesCodex
  • Terminal sessions persist across restarts, tabs, splits, paths, colors, groups
  • Notes and terminal live in the same window, connected by AI
  • Resume any session exactly where you left off, zero daily setup
  • One local workspace for commands, notes, AI reasoning, and technical memory

Real workflows

Where NotesCodex fits in your day

Not a tool you open once a week. A workspace you keep open all day.

Multi-step debugging

You are investigating a production bug. Terminal output, log analysis, hypothesis notes, and fix attempts all happen in the same window. Close the app, come back tomorrow, everything is there.

Codebase onboarding

New project, unfamiliar code. You run commands, read files, take notes on architecture. The AI tags and connects your notes as you go. In a week, you have a navigable map of the codebase.

Long refactoring sessions

A refactor spans days. Decisions, trade-offs, and reasoning sit next to the terminal where you test them. Nothing gets lost between sessions.

AI-assisted terminal work

You launch Claude Agent on a task. It works autonomously in a terminal tab while you keep writing notes in another. When it finishes, the context is already connected.

Operational knowledge base

Commands you run every week but can never remember. Config snippets. Deployment steps. They live in your workspace, tagged and searchable, not buried in a .txt file.

Features

How it keeps your context alive

Every feature exists to reduce context loss. Nothing here is decorative.

Integrated Terminal

Your terminal and your notes in the same window. Split panes, run parallel tasks. No more switching between apps to check what you wrote while debugging.

Session Persistence

Close the app with 8 tabs open. Reopen it tomorrow. Everything is exactly where you left it: tabs, splits, directories, colors, groups. Zero daily rebuilding.

Tab Colors

Assign colors to terminal tabs so you can find the right session instantly. When you have 10+ tabs open, this saves real time every day.

Tab Groups

Group tabs by project. Switch between projects with one click. The tabs you are not using stay alive in the background, ready to resume.

AI Enrichment

Save a note and the AI does the rest: title, type detection, language, up to 5 tags, summary, project assignment, and relationships with other notes. Your memory organizes itself.

Agent Mode

Describe a task, press Enter. Claude Code works autonomously in a terminal tab while you keep writing notes in another. Context stays connected.

Knowledge Graph

The AI links your notes automatically: related topics, dependencies, contradictions. Instead of searching, you navigate your technical memory visually.

Git Panel

See branch, staged files, diff stats, and last 10 commits in a sidebar. It follows the active tab, so the git context updates as you switch projects.

Snippets

Promote any note to a snippet. Commands, code blocks, configs you reuse often get a dedicated view. One click to copy. Your operational cookbook.

AI Search

Search by status, project, type, language, or tag. Or ask in natural language and the AI finds the most relevant note and generates a consolidated answer from your workspace.

Flexible Layouts

One click switches between horizontal and vertical layouts. Portrait monitor? The whole interface rearranges. Your workspace adapts to your setup.

Your Machine, Your Data

All data in local SQLite. Cloud sync via your own Firebase is optional. 15MB installer, no dependencies, no account. Your technical context never leaves your machine.

Pay Once, Own Forever

No subscription. One purchase, lifetime license, all updates included. Built with Tauri v2 and Rust. The workspace is yours.

Settings
NotesCodex settings panel with AI provider and cloud sync configuration

Configure AI provider, Claude Agent, and cloud sync - all optional.

Who is it for

Built for people who build things

NotesCodex sits where your notes meet your terminal. If any of these sound like you, it was made for your workflow.

Vibecoders

You build with AI - describe what you want, let the agent write the code. NotesCodex is where it all happens: AI agent in the terminal, notes auto-organized, everything connected in a knowledge graph.

Developers

You write code, debug, deploy, and document - often at the same time. You need your terminal, your notes, and your AI in one window instead of alt-tabbing between 5 apps.

DevOps & SysAdmins

You run commands all day and forget which fix worked last Tuesday. NotesCodex captures your commands, tags them automatically, and lets you search them by what they do.

Technical Leads

Architecture decisions, meeting notes, code reviews, snippets. Everything documented and connected in a knowledge graph you can actually navigate.

Freelancers

Multiple projects, multiple clients, zero time to organize. The AI handles tagging and project assignment. You search "that nginx fix for client X" and actually find it.

Privacy-First Users

Your notes contain credentials, internal URLs, proprietary code. NotesCodex runs 100% on your machine - including the AI. No cloud required.

Not a notes app. A workspace.

Honest take

NotesCodex is not for everyone

And that's fine. Here's how to tell if it fits your workflow.

It's for you if...
  • You take notes fast and organize later
  • You work in the terminal daily
  • You want AI to connect your notes, not just store them
  • You care about owning your data
  • You're tired of paying monthly for tools you barely use
It's probably not for you if...
  • You prefer visual, drag-and-drop note editors like Notion
  • You need real-time collaboration with a team
  • You never use a terminal
  • You want a polished, consumer-grade experience - this is a power tool
