Use ChatGPT like your local coding agent.

ThinkForge lets ChatGPT actually work on your project — read your files, search the repo, make precise edits, run your tests, and show you a clean diff before anything changes. It all runs on your own machine, across the project folders you choose, powered by the ChatGPT plan you already pay for.

// why thinkforge

Everything Codex does — on the ChatGPT plan you already have.

Codex is powerful, but its coding usage runs out fast. ThinkForge gives ChatGPT the same kind of hands-on coding abilities, running through the ChatGPT app instead — so you get far more room to work, and your Codex usage stays untouched for when you really need it.

Strong reasoning models

Put the best models your ChatGPT plan offers — like GPT-5.5 with high reasoning — to work directly on your codebase.

Uses your ChatGPT plan

It works through the ChatGPT app you already subscribe to. No extra model account, no separate API bill.

Keeps your Codex usage

Because it runs through ChatGPT, it spends your ChatGPT usage — not your Codex limits. Your Codex allowance stays reserved.

Same hands-on coding

Read, search, edit, run tests, review diffs, and hand off work — the real coding-agent loop, not another paste buffer.

// the problem

Coding with ChatGPT turns into copy-and-paste.

You spend your time shuttling code between a browser tab and your editor by hand. ChatGPT never really sees your project, and nothing it suggests is checked against your machine.

It forgets your project

ChatGPT only knows what you last pasted. It loses track of your file layout, related code, and earlier decisions.

You move every file by hand

Copy out, paste in, copy back. Every round trip is slow and easy to get wrong.

You get blobs, not edits

Instead of a precise change to a real file, you get a chunk of code to re-integrate yourself.

Nothing gets verified

Your tests, lint, and build never run, and you can't see a diff before it touches your repo.

// the solution

Give ChatGPT a real, private workspace.

Install the app, paste your license key, pick your project folders, and paste one URL into ChatGPT. From then on you just talk to ChatGPT — and it works directly across your projects.

01 Install the app
Download the ThinkForge installer and run it. Windows 10 & 11.
02 License key & folders
Paste your license key and point ThinkForge at your project folders — add more anytime. No accounts or tokens to set up.
03 Paste the URL into ChatGPT
Click Start, copy the connector URL from ThinkForge, and add it once in ChatGPT's connector settings.
04 Just ask ChatGPT
Ask it to explore, fix, build, or verify. It works across your active projects and shows you every change.

// features

Built to feel like a real coding agent.

Multiple workspaces at once

Add your frontend, backend, and shared library — or several client projects — then check the ones you want active. ChatGPT can read, edit, and run commands across every active folder in the same conversation, no reconnecting or switching required.

Lightning-fast repo search

One smart search blends ripgrep, filename matching, a live code graph, and git history to find exactly what matters in big repos — fast.

Local caching, lower cost

Results are cached on your machine, so ChatGPT doesn't keep re-searching the same things. That trims token cost and keeps long chats sharp instead of drifting.

Seamless chat handoff

Hit a chat's limits? Start a fresh one and ThinkForge hands over right where you left off — pulling the context from your machine, so you never re-explain the project.

Precise edits

ChatGPT makes exact changes to real files inside the project folders you've activated — nothing outside them.

Runs your checks

It can run your tests, lint, typecheck, and build to verify a change actually works — with a safe command set by default.

Review every diff

See a clean, color-coded diff of what changed before you keep it. Nothing sneaks in.

Plan-and-execute handoff

Let ChatGPT write the plan, then have a local agent carry it out — and send the results back for review.

Cross-platform installer

A simple installer for Windows. No terminal gymnastics to get started.

Security-first defaults

A private, protected connection, locked-down project folders, and sensitive files blocked out of the box.

// straight talk

Clear about what it is.

ThinkForge works with the ChatGPT account you already have. It doesn't sell, share, or change anyone's model access — it just makes your own ChatGPT far more useful for code.

What it is

a local bridge that connects ChatGPT to the project folders you choose on your machine
a way to run your own ChatGPT plan as a coding agent
a repo-aware loop: search, edit, verify, review
seamless handoff between chats and to a local agent
a private, protected, user-controlled connection

What it isn't

not a way to get around rate limits or plan limits
not a model reseller, proxy, or account-sharing service
not a replacement for your ChatGPT subscription — you still need one
not an operating-system sandbox
not a promise that every account, model, or region can connect

// how it works

From a prompt to a verified change.

Your request goes through your own ChatGPT and a private connection you control to a small helper running on your machine. It works across your active project folders and sends the results and diffs straight back to the chat.

Ask ChatGPT to explore the project — it searches and reads only what it needs.

Approve a change — it makes a precise edit inside the right project folder.

It runs your tests or build to check the change really works.

You review the diff, then keep it — or hand off to a fresh chat.

// setup

Up and running in about a minute.

No accounts, no tokens, no domains to set up. Install the app, paste your license key, pick a folder, and you're connected — after that, you just open the app and start.

1 Install & open the app
Run the one-click installer for Windows, then open ThinkForge.
2 Paste your license key
Copy the key from your purchase email and drop it into ThinkForge. One time, one click.
3 Pick your project folders
Choose one folder to start — add more anytime from the Workspaces tab. Nothing outside your active folders is exposed.
4 Click Start
ThinkForge connects out to its hub — nothing to expose on your machine, no tunnel to configure.
5 Copy your URL into ChatGPT
Paste it into ChatGPT → Connectors with authentication set to None, and you're connected.

// security

Your code stays on your machine.

ThinkForge is built with layered protections to keep your project as safe as possible. It runs locally, you stay in control, and you review every change before it lands.

Built to protect you

Your connection is private and tied to your license key.
ChatGPT can only touch the project folders you choose to activate.
Commands run in a safe, limited set by default.
Your files, edits, and commands run on your machine — the hub only routes your connection and never stores your code.
You see and approve every change before it's kept.

Sensitive files stay off-limits

secret files like .env and API keys
private keys and login credentials
your .git internals and node_modules
build and cache folders
anything outside your chosen project folder

No software can promise perfect security. ThinkForge reduces risk with strong defaults, but you should still use it with projects you trust and keep your own backups.

// faq

Good questions, straight answers.

What is ThinkForge, really?

It turns ChatGPT into a coding assistant that can actually work on your project. Instead of copy-pasting code back and forth, ChatGPT reads your files, searches your repo, makes real edits, runs your tests, and shows you a diff — all on your own computer, across the project folders you choose to connect.

Do I still need a ChatGPT subscription?

Yes. ThinkForge works through your own ChatGPT account — it doesn't include or replace one. The upside: it puts the plan you already pay for to work as a hands-on coding agent.

Does it use up my Codex usage?

No. ThinkForge runs through the regular ChatGPT app, so it uses your ChatGPT usage — not your Codex limits. Your Codex allowance stays reserved for when you actually want it.

What model does it use?

Whatever strong models your ChatGPT plan gives you, including GPT-5.5 with high reasoning. That means you can get serious, Codex-style coding done straight from the ChatGPT subscription you already have.

Does it get me around any limits?

No — and we're careful about this. ThinkForge doesn't lift, dodge, or change anyone's plan limits. It simply lets your ChatGPT plan, which comes with its own separate allowance from Codex, do a lot more of your coding. Normal plan limits still apply.

Is my code uploaded anywhere?

Everything runs on your machine. ThinkForge only shares the specific files, snippets, search results, and diffs with your own ChatGPT chat when you ask it to do something. There's no separate ThinkForge server storing your code.

How does the handoff between chats work?

When a chat gets long or hits its limits, you just open a new one. ThinkForge quietly saved the important context on your machine, so the new chat picks up right where the last one stopped — no re-explaining the project, and no relying on ChatGPT to "remember." It keeps long projects moving and stops chats from getting fuzzy over time.

Can ChatGPT work across more than one project?

Yes. In the Workspaces tab, add the project folders you want ChatGPT to see and check the ones that should be active — a frontend, a backend, and a shared library, for example. ChatGPT can then read, edit, and run commands across all of them in the same conversation, without reconnecting or switching folders. One folder is marked primary for tools that only make sense against a single repo, like Git.

How fast is the repo search?

Very. It combines several search techniques — plain text search, filename matching, a map of your code, and git history — into one step, then caches the results locally. So ChatGPT finds things quickly and doesn't waste time (or tokens) searching for the same thing twice.

Which platforms are supported?

Windows 10 & 11, through a simple installer. You don't need to be comfortable in a terminal to get started.

How much does it cost?

It's free during early access — no card, no subscription. You just download it and activate with your email. You'll still need your own ChatGPT plan (ThinkForge runs on the plan you already pay for). We may add paid plans later, but early-access users get in free.

Will it work with my ChatGPT account?

You'll need a ChatGPT account where connector/Developer Mode features are available and turned on. Not every account, model, or region can connect, so we can't promise it works everywhere — but setup will tell you quickly if you're good to go.
