Repertory software is a digital version of the homeopathic repertory — the structured index of symptoms (rubrics) and the remedies known to cover them — that lets you search rubrics, select a patient's characteristic symptoms, and instantly tabulate which remedies best fit the case. In place of the printed volume and the hand-drawn paper grid, homeopathic repertory software gives you full-text search, multiple repertories side by side, and an automatic repertorisation chart that updates the moment you add or remove a rubric.
For more than a century, repertorisation meant turning pages and tallying remedies by pencil. Today, the same logic runs in seconds. This guide explains what repertory software actually does, how digital repertorisation works under the hood, the features that genuinely matter when you choose a platform, and how free and paid options compare — written for practising homeopaths and students rather than for shoppers chasing a download link.
What Is Repertory Software?
A repertory is the homeopath's index. It catalogues symptoms as rubrics — for example, "Mind; anxiety; health, about" or "Head; pain; pressure, ameliorates" — and lists under each rubric the remedies known, through provings and clinical experience, to produce or cure that symptom. Repertory software is simply that index made digital, searchable, and analysable.
The difference is not cosmetic. A printed repertory such as Kent's Repertory contains roughly 68,000 rubrics; modern repertories run to hundreds of thousands. Finding the right rubric by hand, then cross-tabulating remedies across a dozen selected symptoms, is slow and error-prone. Repertory software does three things the book cannot:
- It searches. Type a symptom and the software finds every matching rubric across one or many repertories at once.
- It tabulates. Select your rubrics and it builds the repertorisation grid automatically, ranking remedies by how strongly and how often they cover your symptoms.
- It connects. From a ranked remedy you can jump straight to its full materia medica entry to confirm the picture — no second book, no lost place.
This is why repertory software has become the backbone of digital homeopathic practice. If you are weighing up a full platform with repertory, materia medica and case management together, see our broader homeopathy software with repertory and materia medica guide; this article stays focused on the repertory dimension specifically.
From Paper Grids to Instant Analysis: How Digital Repertorisation Works
Understanding what the software automates helps you trust — and sense-check — its output.
The manual method
In classical, pen-and-paper repertorisation, the practitioner draws a grid. Each selected rubric becomes a column; each remedy that appears in any of those rubrics becomes a row. You then mark every remedy in every rubric, noting its grade (the degree to which the remedy is associated with that symptom), and add up the columns. Remedies that appear across the most rubrics, at the highest grades, rise to the top of the analysis. It is rigorous and educational — and it can take the better part of an hour for a single chronic case.
What the software automates
Digital repertorisation follows exactly the same logic, only the tabulation is instant:
- Search for each characteristic symptom and pick the rubric that best matches the patient's own words.
- Add the rubric to your analysis. The software pulls in every remedy listed under it, with its grade preserved.
- Repeat for your five to ten most characteristic symptoms.
- Read the chart. The platform ranks remedies by total score and by how many of your rubrics each one covers, usually colour-coding grades so the strongest associations stand out.
Crucially, the software does the arithmetic, not the thinking. It will tell you that, say, Lycopodium covers eight of your nine rubrics at high grades — but whether Lycopodium is the simillimum is still your judgement, confirmed against the materia medica and the totality of the case. Good repertory software makes the mechanical work disappear so you can spend your attention on symptom selection and remedy differentiation, which is where cases are actually won or lost.
Repertory Software vs the Printed Repertory
The printed repertory served homeopathy faithfully for over a century, and many practitioners still keep one on the shelf. But for day-to-day case analysis, software offers advantages that are hard to ignore:
| Printed repertory | Repertory software | |
|---|---|---|
| Finding a rubric | Manual page-flipping; you must know the classical heading | Full-text and semantic search in seconds |
| Repertorising | Hand-drawn grid, manual tallying | Automatic, instantly updated chart |
| Multiple repertories | One book at a time | Kent, Murphy, Boenninghausen, Complete and more, side by side |
| Materia medica check | A separate set of volumes | One click to the integrated entry |
| Portability | Heavy volumes | Laptop, tablet or phone |
| Case records | Paper notes | Cases saved and synced automatically |
The point is not that the book is obsolete — its structure is still worth learning — but that software removes the friction that discourages thorough repertorisation in a busy practice.
What to Look for in Homeopathic Repertory Software
Not all repertory software is equal. When you evaluate a platform, these are the features that make the difference in real clinical use.
Multiple classical repertories
A single repertory gives you one author's view. The best homeopathic repertory software lets you work across several — Kent for its classical rigour, Boenninghausen for generals and concomitants, Boger for pathological generals, and Murphy or the Complete Repertory for breadth and modern clinical rubrics. Being able to compare how different authors handle the same symptom is one of the strongest reasons to go digital. For a deeper look at how these differ, see our comparison of Murphy's vs Kent's vs the Complete Repertory.
Rubric search — including semantic search
The oldest hurdle in repertory work is the gap between how a patient describes a symptom and how the repertory phrases it. A patient says "I feel a tight band around my head"; the rubric reads "Head; constriction; band, as if." Traditional search needs you to know the classical wording. Semantic search closes that gap — you type the patient's language and the software maps it to the correct rubrics. For students especially, this turns the repertory from an intimidating glossary into a usable tool from day one.
Grading, weighting and analysis views
Good software preserves the three-grade system and lets you weight rubrics by importance, so a single highly characteristic symptom can carry more influence than several common ones. Look for clear analysis views: a sortable chart, the ability to see which remedies cover which rubrics, and the option to eliminate or emphasise particular symptoms as you refine the case.
Integrated materia medica
Repertorisation is never finished until you confirm the remedy in the materia medica. Software that keeps repertory and materia medica in one place — so you can move from a ranked remedy straight to Boericke, Clarke, Allen or Kent without switching tools — saves time and keeps your reasoning continuous.
Case management and cloud sync
The repertory analysis is most useful when it lives alongside the case. Platforms that save your repertorisations, prescriptions and follow-ups, and sync them across devices, help you build good habits and review what worked. Begin a case at your desk, review it on your phone, present it on a tablet.
Data security
You are handling sensitive patient information. Favour software with proper encryption and a clear privacy posture; if you practise in a regulated jurisdiction, confirm it meets your obligations before you store real patient data.
Free vs Paid Repertory Software
Because the classical repertories are in the public domain, you do not have to pay simply to access Kent or Boenninghausen. That changes the question from "can I afford repertory software?" to "which features justify a paid plan?"
Free repertory software typically gives you the classical repertories and basic repertorisation. That alone is enough to learn the craft and analyse straightforward cases. Similia, for example, includes seven classical repertories, semantic search, twelve classical materia medica books and case management on a free-forever plan — no credit card, nothing to install.
Paid plans generally add breadth and power: the larger modern repertories, AI-assisted symptom extraction, advanced analysis, and tools for high-volume practice. Whether that is worth it depends on your caseload. A student or occasional prescriber may never outgrow a good free tier; a full-time practitioner usually will.
A note on "free download" searches: much of what is advertised online as free downloadable repertory software is either outdated, unsafe, or pirated commercial software. There is no need for any of it. Modern, legitimate repertory software runs in your browser — you simply open the repertory and start, with the public-domain repertories included at no cost.

Repertory Software for Students
For students, repertory software is as much a learning aid as a clinical one. Semantic search lets you find rubrics before you have memorised classical terminology. Working across several repertories shows you how different authors organised the same symptoms. And an instant chart lets you test "what if I add this rubric?" in a way the paper grid never could, building intuition case by case. The one caution: learn the manual logic too. Knowing why the chart ranks a remedy where it does is what stops the software becoming a crutch.
Getting Started
If you have never used repertory software, the fastest way to understand it is to try one case. Take a well-documented teaching case, select five or six characteristic symptoms, open an online repertory, and watch the chart build as you add each rubric. Then confirm your top two or three remedies in the materia medica.
Similia offers a free tier with seven classical repertories, semantic search and integrated materia medica, so you can explore repertory software without cost or installation. The repertory has been the homeopath's most trusted companion for two centuries — software simply lets you use it at the speed of a modern practice.
Frequently Asked Questions
What is repertory software?
Repertory software is a digital homeopathic repertory: a searchable database of rubrics and the remedies that cover them, with automatic repertorisation. You select a patient's characteristic symptoms and the software instantly ranks the remedies that best fit the case, replacing the manual paper grid.
Is there free homeopathic repertory software?
Yes. The classical repertories — Kent, Boenninghausen, Boger, Hering and others — are in the public domain, so several platforms offer them at no cost. Similia includes seven classical repertories with semantic search on a free-forever plan, with no credit card and nothing to download.
Do I need to download repertory software?
No. Modern repertory software runs in the browser, so you can repertorise on any device with no installation and your cases saved to the cloud. Beware "free download" listings, which are often outdated or pirated; legitimate online repertory software gives you the public-domain repertories without any download.
Which repertory should I start with?
Most educators recommend beginning with Kent's Repertory, since its structure underlies nearly every modern repertory. Once you are comfortable with Kent, exploring Murphy's clinical organisation or the breadth of the Complete Repertory will make immediate sense — and good software lets you switch between them instantly.
Can repertory software choose the remedy for me?
No, and it should not. Repertory software narrows and ranks the candidates, but the simillimum is confirmed by matching the remedy's full picture to the patient in the materia medica, using your clinical judgement. The software is a compass that points you in the right direction, not an autopilot.
What is the difference between repertory software and materia medica software?
Repertory software works from symptoms to remedies: you enter rubrics and it ranks the remedies that cover them. Materia medica software works in the opposite direction, giving you the complete symptom picture of a single remedy so you can confirm it. A good platform integrates both, so repertorisation flows straight into confirmation within one workflow.
