Threadwrench

Stop searching for weeks. Find the thread that fixed it.

Every plan searches enthusiast forums and Reddit the way owners actually word things, reads the threads, and shows the fix quoted from the person who did it, with a link.

Prices in USD. After you pay, you get a Threadwrench key that unlocks your plan. It's saved in your browser, and you can enter it on any device. Subscriptions renew automatically and can be canceled any time. See the terms and privacy policy.

Threadwrench users are working on their own cars, with a specific problem, right now. Parts sellers, shops, tool brands and tuners can reach them next to the search results, matched to the make they're working on.

We'll email you rates and options.

Questions

Why are there ads on the free plan?

They help pay for the searching and AI reading behind every result. Ads are always labeled, never mixed into the thread results, and paid plans have none.

What counts as a search?

One problem description. Threadwrench runs about 10 forum searches and reads up to two dozen threads behind the scenes, but that all counts as one.

Does Threadwrench tell me what's wrong with my car?

It shows what people with the same car and the same symptoms found, quoted from their threads. Interpret mode adds a written read of those threads, and every point links back to the thread it came from.

What's Interpret mode?

The AI reads the matching threads and reasons through your case: what's most likely, what your tests rule out, and what to check next. It only uses what the forums say.

Does it work on swapped and modified cars?

Yes. Add your swap and ECU and it searches the engine and ECU communities too, not just your chassis.

What if it doesn't find a solved thread?

You get free re-searches. Keep the same car, add more detail (exact sounds, when it happens, what you've already replaced) and search again. Up to 2 per search (1 on the Search Pack), within 48 hours, and they don't count against your plan.

Do unused searches roll over?

Monthly searches reset each billing period. Search Pack searches don't expire.

Can I cancel?

Any time, from the "Manage subscription" link on the search page, or through the link in your Stripe receipt email. You keep your plan until the end of the period you paid for.
