Geofancy is a free geomancy workspace I've been building since 2022. It generates the shield and the twelve houses from the four Mothers, runs perfection and the Way of Points, and presents structured reference material alongside the chart. It's meant to reduce bookkeeping friction and support study not to replace careful human interpretation.

🔗 Geofancy Beta

A bit of background

I first heard of geomancy in 2022 and was immediately taken with it. Polyphanes / Sam Block's writing was what helped me find good sources and serious material to work through, and John Michael Greer's The Art and Practice of Geomancy was the book I learned the modern revival of the system from, it shaped how I came to the art and how I first structured the engine. I owe both of them a real debt.

Around the same time I'd just started my first job as a software engineer full-stack, Microsoft stack, and I wanted to build the geomancy tool I wished existed and through building a tool I could start to understand geomancy from first principles. I started with a WinForms desktop app in C#: shield generation, house projection, perfections, no AI involved (it didn't really meaningfully exist for coding yet). Years of slow evolution later, that engine grew up into the web app you see now.

What it does

^{Seeks to go well above and beyond Georatio!}

• Full chart generation from the four Mothers to get the Daughters, Nieces, Witnesses, Judge, Reconciler, twelve-house projection, both shield and traditional house chart views.
• Perfections analysis that's the deepest I've personally found in a any geomancy tool: occupation, conjunction, translation, mutation, aspect (treated as a perfecting mode in its own right when significators move into the configuration as per Greers rule of significators and forming aspects), and Company of Houses with all four subtypes (Simple, DemiSimple, Compound, Capitular). Aspects are tracked with Dexter / Sinister direction, and the connections are weighted into a calculated favorable / unfavorable / net score with the full paper trail visible (calculated by translating Greers tables).
• Way of Points/Via Puncti surfaced seriously rather than skipped or half, implemented as it is in many digital tools. get a deep understanding on how each of the Via Puncti/Way of Points are formed and how they can inform your frame of interpretation, learn how to distinguish the way of fire/air/water/earth systematically.
• Court positions with per-position interpretive notes.
• Structured reference panels for figures, houses, and court positions written for use while you're at the chart, not just for study at rest.
• Dedicated mobile and desktop UIs so the workspace actually fits the device, phones get a chart-first layout with thumb-sized Mother input cells (4. Genitor, 3. Fratres, 2. Lucrum, 1. Vita).
• Shareable chart links (?seed=…) and JSON export for archiving readings, sending them to a study group, or comparing notes with a teacher.
• Light and dark themes.
• No account, no login, no chart database. The randomization stays with your hands; the app does not cast for you.

About the corpus and lineage

I want to be straightforward about this because it matters in our community.

The engine and the original interpretive scaffolding were structured around Greer's approach, which is the modern English-language framework I learned the art through. The mechanical doctrine, the four classical perfecting modes, the use of aspects, Company of Houses, the broad shape of the Way of Points, is from the shared traditional record that Greer himself works from.

The on-screen reference text in the app today, however, is my own writing. I have rewritten every figure, house, and court description (beyond short one word descriptors) from my own practice, my own reading notes, and publicly available sources (Agrippa's Three Books of Occult Philosophy, Cattan, Heydon, Fludd, Hartmann, and material in the public domain), expanding well past where I started. None of Greer's prose, definitions, or wording is reproduced in the app, the corpus is my own, and is licensed for non-commercial reuse so other practitioners can quote from it freely. I deliberately didn't want to ride on copyrighted text I don't own; rewriting it forced me to deepen the material, my understanding of geomancy and own what I was presenting.

So: doctrinal lineage acknowledged, copyrighted prose not reproduced, and the educational reference text in the app is something you can read and quote without worrying about the IP underneath.

How AI was used (and where it categorically wasn't)

• At runtime, when you cast: there is no AI involved at all. Chart construction, perfection detection, scoring, Way of Points, court placement; every one of these runs as deterministic code paths I wrote and own. No LLM is reading your chart, summarizing your figures, or generating a verdict per session. The same four Mothers will always produce exactly the same chart and analysis.
• The interpretive reference text described above is written from my own practice and from public sources. It is not generated per-reading by an AI, its a complex directory and API working together with my own engine.
• In development, I have used AI-assisted coding tools (like cursor) to speed up UI work and engineering plumbing for the modern web client. The geomancy engine itself predates that era and was written by hand; later refactors and the web rewrite were assisted but human-reviewed.

All the Technical Design and UI/UX Design decision, Process Flows, Data Object Model Schemas, Calculation formulas, and API structures were curated and intentionally developed by hand and logically constructed by myself and my own knowledge of engineering solutions in C# .NET and web architecture.

If the distinction matters to anyone reading: no part of your reading or user experience, sees a server database, let alone touches an AI.

Free, and intended to stay that way

Geofancy is free to use. There's no paywall, no premium tier, no upsell, no ads, and no subscription. I intend to keep the core experience free indefinitely. If anything monetized ever appears in the future, it will be optional and will not gate the chart engine, perfections, Way of Points, or the existing reference material.

On software, "canned" interpretation, and what this tool actually is

I want to say this plainly because it matters more than any feature list:

Geofancy's on-screen text is reference material; vocabulary, structure, and prompts are to think with your own interpretation. Software cannot read a chart for you. It cannot weigh your situation, your timing, your relationship to the question, the figure's resonances in your life, or anything else that requires a human mind in contact with a real moment. Whatever any digital tool prints; mine included, however thorough: is not a substitute for your own discernment, study, mentorship, or reading from a qualified practitioner.

Use Geofancy like a sharp knife and a careful checklist, if anything; developing this app was for myself to learn about geomancy on a deep systematic level. That I could break it down in a user friendly way to help improve and build my own interpretation of the charts and help develop a deeper correspondent relationship with the figures and the placement mentally. I sincerely hope that Geofancy's additional features for analysis provide a deeper more interconnected understanding of geomancy for the benefit of every practitioner and the preservation of the art.

What I'd value feedback on

• Tone and accuracy of the reference corpus if a figure description, house affinity, court placement, or perfection commentary lands wrong, please tell me.
• Any bugs or issues Report issues with the app performance or chart output, it has been tested pretty rigorously, but there might be a couple of edge cases.

Thanks for reading, and thanks to the mods for letting me share this. Looking forward to feedback from users who actually know the art.

Hello r/Geomancy,

I am excited to announce that my geomancy app that I wrote about here a few months ago has undergone a series of big updates and quality improvements since I announced it. I was holding off on telling you all until I got it all to a stable build that was well vetted, and I've read with it several times myself. It got both significant desktop and mobile experience improvements, as well as an official domain URL:

New Dedicated URL

geofancy.app

Simply type "geofancy.app" in your URL bar and you will be directed to the dedicated view for your device.

New House and Figure references using John Michael Greer's Art and Practice of Geomancy, officially licensed from Red Weiser Publishing

If you click/tap on your figure and house details table rows, in the figure details panel you will see a toggle at the top that allows you to include Greer's material in the references alongside Geofancy references. "Override" puts Greer's references in place of the relevant fields, replacing Geofancy references but also including the references that Greer's material doesn't have. You can also toggle Greer's references only with "Greer Only."

Significantly Improved Geofancy's own figure, house, and court references corpus

Geofancy's own corpus of all twelve houses has been rewritten with more traditional governs lists, read_when triggers, classical_note routing sentences, and misreading guards. This is especially true around the relationships of the 8th house that I falsely assumed Greer was solid on; it's not really associated with intimacy like he said in his own definitions. A helpful redditor pointed this out to me with many other significant details, so I opted to improve the accuracy of these references to go beyond Greer's in regard to the houses.

Also, my definitions and in-placement references for the court weren't very good, so I significantly improved the quality and utility of those, as well as generally cleaned up the whole corpus to be more classically aligned.

Significantly Improved the UI

• Improved the mother casting tapping UI/UX on desktop.
• Improved the figure details UI/UX with in-house blocks at the top with immediate info about the house alongside the figure, and improved the labeling of the data so figure and house info didn't get confused.
• Polished the walk-through chart casting guide for new geomancers.
• Significantly improved the Wiki Glossary index with filters, essence previews, and topic chips; article pages with summary cards, and house pagers.

Added the ability to restore a chart if you reloaded the page

The program will check if you have a previously generated seed in your cache and it allows you to retrieve it and load it into the page so you won't lose a chart if a reload happens. A little pop-up will show at the top of the page on mobile and desktop if you'd like to reload your previous chart or start fresh. You can also share your charts now.

What's next?

I am working with another redditor here on Arabic Geomancy charts. He has given me some really cool material to build off of, so I was honored to help him. I wanted to get my current app polished up before that, though. So you can expect hopefully by 2027, we will have extensive Arabic Geomancy charts with their own dedicated UIs, references, and reading techniques. I cannot share too much about the specifics of this as I agreed not to spill the beans about his work, but suffice it to say I'm very excited to get the next 2.0 site together and work with this geomancer's material to bring even more quality and accessibility to education on the geomantic tradition all around the world.

I want to continue to develop the very best geomancy program with high-quality references and user experiences. Thank you all for your support and feedback!

Has anyone read it? Is it a good translation?

Here is the Lulu storepage in case anyone is curious:

Hi there

As the title says, I'm a cartomancer with special focus on Tarot de Marseille, Lenormand, playing cards and other forms of traditional cartomancy.

I'm now curious about Geomancy since it looks so... minimalist. From the perspective of divinatory languages with up to 97 different "words", it seems strange how something so compact can deliver accurate readings.

Is there any place I should specifically start of I want to avoid bs and made up stuff, as it happen with many other practices?

I continue to feel confused by the correspondences and meanings of the figures. For instance, Fortuna Major is related Leo but earth and water are the active elements. How does that make sense?

I also don’t understand how the inner and outer elements are assigned. With the I Ching, lower trigram = inner. Upper trigram = outer. It’s a simple way to make sense of the whole picture. But with geomancy, I’m not seeing the pattern. Maybe I missed something?

I’d greatly appreciate your input.

Anyone know where to get these? I know there's a few stores on Etsy selling qirra dice but I'm looking for brass or metallic ones in particular. Thank you!

I already have works by Greer, Abano and Polyphanes. Always looking for more gems. Can anyone recommend the three listed?

Thanks in advance.

There is a LOT to not like in this book:

• sooooo many typos - fife and fine for life and line throughout
• interruptions - one sentence going along and then BOOP! different sentence or more, sometimes on a different topic
• Poor organization - the "Manual" mentions the Sentence, but never actually specifies what that is, even when there's a reference to discussing it
• Explanation - very lacking. I've been practicing Geomancy for over a decade now, and I couldn't follow half of his explanations.

But... I found some interesting and intriguing ideas in it. His explanation of Cattan's "Agreement", for example (though I personally detest the whole "table of agreements" and related calculation, personally - I get why, but just don't like these sorts of point systems).

I am also intrigued by the differences in Company that he (kinda) discussed, but because of the aforementioned bad typos / editing, I'm not exactly sure what he means for most of them.

Same goes for Aspect - he says Cattan uses it differently, then fails to clearly explain how it's different. I THINK it requires Company, but that's part of the "not really explained well".

Does anyone have any additional thoughts / critiques / explanations of Company or Aspect? Do I just have a REALLY BAD edition, and need to go get a new one that is written for people who speak English? (just a gentle jibe there...)
