Turn your AI conversations into documents anyone can read.
NetCodex finds the chats that Codex, Claude Code, Copilot, Cursor and other AI tools keep on your computer, and exports them as Markdown, PDF or a web page. Nothing leaves your machine.
Why does the invoice search take several seconds? Can you fix it?
exec_command{"cmd": "psql -c \"EXPLAIN ANALYZE SELECT * FROM invoices WHERE customer_id = 42\""}Seq Scan on invoices (cost=0.00..48211.40) time=3104.882 ms
Codex
The query reads the whole table. I will add an index: CREATE INDEX idx_invoices_customer_date ON invoices (customer_id, issued_at);
Index Scan using idx_invoices_customer_date time=41.207 mspytest: 212 passed in 18.4s
The original transcript: every message, tool call and output, exactly as the tool saved it.
Fixing the slow invoice search
You asked Codex why searching invoices took several seconds.
Codex looked at the database query, found that it scanned the whole table, and added an index on the customer and date columns.
After the change the search took 40 milliseconds. Codex ran the tests and all 212 passed.
Result: the search is about 60 times faster, with no other changes.
The readable view: the same conversation retold in plain language, ready to share.

NetCodex 0.8.2 keeps conversation export and adds continuity between agents and a local file explorer.
Export one or all
Choose one chat or export every conversation from an agent. Save Markdown, PDF, HTML or Quarkdown under the conversation name, in Documents or your preferred folder. Keep the original transcript or read it in plain language.
Continue in another agent
Choose a detected AI application, review the project and select attachments. Prepare a compatible new session or a portable package with the full history and a continuity summary.
Find your files
Browse agent folders and temporary files, filter by origin and type, preview images, text and PDF, and save copies of selected files. Files without a confirmed origin appear as Unidentified.
Integrated import is available for compatible Codex CLI and Claude Code variants. Desktop apps, extensions and other agents have their own capabilities; when integration is unavailable, NetCodex explains the manual steps. Original conversations are preserved.
Three steps from chat to document
No setup and no configuration files. NetCodex reads each tool's history where it already is.
1
Open NetCodex
It looks for Codex, Claude Code, Copilot, Cursor, Gemini CLI and the rest, and shows how many conversations each one has.
2
Pick conversations and a look
Keep the conversation as it looks, or switch to the readable view. Choose a template for PDF and web pages.
3
Export to a folder
Markdown, PDF, HTML or Quarkdown files land in a folder you choose, with an index. Next time, only new chats are added.
Two ways to read the same conversation
Sometimes you need the exact record. Sometimes you need something a colleague can read in two minutes. NetCodex gives you both from the same chat.
tool_call: exec_commandoutput: 212 passed
As it looks (original)
Every message, command and tool output in order. Best for audits, debugging and keeping a faithful record.
Plain language (readable)
The same conversation retold as clear prose: what was asked, what was done and what came out of it. Best for sharing.
Templates for documents worth sending
PDF and web exports come with layouts for different readers. Pick one when you export; you can change it any time.
Chat
A clean chat: one bubble per speaker, the assistant's actions folded away.
Transcript
Interview style with the time of every line: who said what, and when.
Report
Summary and key facts first, then the dialogue, then every action.
Book
Serif typography, one chapter per working day and a table of contents.
Minimal
Plain and compact text, ready to read or paste somewhere else.
Private by design
Reads in place
Chats are read from the folders where each tool keeps them. Nothing is copied to a server.
No account
There is nothing to sign up for. NetCodex has no cloud, no tracking and no history of its own.
You choose what to share
Local file paths are left out by default, so exports are safe to send.
Your conversations are already on disk.
Each tool keeps its chats in its own folder. Here is where, on Windows, macOS and Linux. Once installed, netcodex where lists the ones on your machine.
No. NetCodex runs on your computer and reads each tool's chat history in place. Exports are written to a folder you choose. There is no account and no upload.
Which AI tools are supported?
Codex, Claude Code, Claude Desktop, Claude.ai exports, GitHub Copilot Chat and CLI, Cline, Cursor, Gemini CLI, Continue, Aider and Antigravity. Windsurf and Trae encrypt their history, so they cannot be read.
What is the readable view?
It retells a conversation in plain language: what you asked, what the assistant did and the result, without raw tool output. The original view keeps every message exactly as it was saved.
Which formats can I export?
Markdown, PDF, HTML and Quarkdown, each in the template you choose. Quarkdown files need the free Quarkdown program on your computer.
How much does it cost?
Nothing. NetCodex is free software under the MIT license.
