General
What is flashcardaudit.com?#
flashcardaudit.com is a tool I built that renders Anki flashcards so an AI auditor can review them. This helps learners ensure that the educational material they are studying is verified to be factually accurate.
What is Anki?#
Anki is open-source flashcard software that has been in use since 2006. It is widely recognized as one of the most effective memorization tools in the world. It is one of my favorite software projects of all time.
Is the code open source?#
No. I don't want anyone trying to exploit the audits or LLMs training on the code. I also think trying to ingest/detect AI slop PRs will make this very unfun for me. The code is great because I'm obsessed with it and have a strong mental model of the entire system. The code will remain proprietary.
Why does it take so long?#
flashcardaudit.com is optimized for quality > cost > speed. My target processing time is 48 hours (but that is an arbitrary number to be honest). In general, I try to underpromise and overdeliver so results should usually be available sooner than the 48 hour target. No promises, but things have been pretty snappy so far.
Do I need to create an account?#
No. flashcardaudit.com uses alien technology to support a login-free experience.
Does it fix the cards for me?#
No. In the current version, the tool provides you with a report to help you identify which cards need to be updated. The process of updating your own cards is likely to be a educational experience.
How did you do the hero animation?#
I hired an amazing HUMAN BEING to do the hero artwork. An incredible artist from Spain, Dima handled both the illustration and motion of the art piece. We collaborated for weeks to create an asset that best captures the flashcardaudit.com system. You can find more of Dima's work at illustratordima.com.
Is this vibe coded?#
Which LLM Model?#
Gemini 3.5 Flash. Most of my infrastructure resides in GCP, so Gemini was a natural choice. I plan to continue to update the models if it means increased intelligence or decreased costs. Right now, I find the Gemini models in particular to be extraordinary in their multimodal capabilities. Also feeling hella bullish on HASSABIS.
Are the audit results private?#
No. But the results are not indexed, which means unless you share the link, it is extremely unlikely that anyone will be able to find your results. You may choose to keep your link private or share it with the world. This is similar to the way "unlisted" videos on YouTube work.
Is it better to do many sample audits or one large one?#
Either works. The system is designed for you to do many smaller samples at whatever pace you choose. Due to Sample Mode and Cached Cards, you never have to pay to audit the same card twice. Though I do recommend starting with a small sample to first test for audit quality.
Why haven't you answered my message?#
I am primarily commited to my full time role in education technology. I work on flashcardaudit.com on nights and weekends, so please be patient and I will do my best to get back to you.
Technical
What are the upload limits?#
The total cards limit is 50,000. The file size limit is 2GiB.
What file formats are supported for file uploads?#
.apkg files. See the tutorial if you need assistance exporting.
Will it handle my flashcards?#
If your note types are simple (KISS), the answer is almost certainly. I've been building battle scars for thousands of note types, but ultimately there will always be note types that I have never encountered before. I recommend starting with a small sample audit to first test for audit quality. See the Compatibility List for more information.
Pricing
How is the pricing determined?#
The pricing is ultimately dictated by upstream AI provider token costs (Google). As the cost of inference fluctuates, my plan is to continually adjust cost of audits. I'm betting that in the future, AI providers will be able to provide smarter, cheaper, and faster inference. These are the very early days of AI.
What payment methods do you accept?#
I use Stripe for all payment processing. If they can do it, I can (probably) do it.
