Connect Codex to Extend

Give an AI agent your Extend account as a tool and it can read documents itself instead of handing them back to you. It can start an extract run on a file, parse and split a stack of pages, classify each document, and spin up a classifier or extractor on the fly, calling each operation as a tool while it works through a batch. It can even launch evaluation set runs to check accuracy before it acts on the results.

What you can build

When a new PDF lands in your inbox or storage, start an Extend extract run and write the structured fields straight into your database.
When an Extend run completes, pick up the extracted data and route it to the right team based on the document type.
Classify every incoming file with a sync classify call, then branch the workflow by document type before extracting.
Split a merged scan of many documents into separate files with a batch split run, then classify and extract each one.
Batch parse a folder of contracts overnight and collect the parsed output for search and review.
Publish a new classifier version, run it against an evaluation set, and compare accuracy before you rely on it in production.

About Codex

Codex is OpenAI's command-line coding agent. NoClick runs it as a hosted agent and lets you connect your apps to it as tools, turning it from a coding assistant into an operator that can act across your systems. Connect an integration to the agent and Codex can query, create, and update records in that app directly. You keep the Codex experience and give it real reach into the tools your team already uses.

Fast, capable code generation and editing
Good at well-scoped, concrete tasks
Strong at API and data manipulation
Familiar to teams already on OpenAI tooling
