The repertory software buyer's guide

Repertory software is the digital descendant of the index volumes — Kent's Repertory, Boenninghausen's Therapeutic Pocketbook, Boger's Synoptic Key — that practitioners have used to map symptoms to remedies since the nineteenth century. A modern package does three jobs: it stores one or more repertories as a navigable rubric tree, it lets the practitioner search and select rubrics for a case, and it computes the remedy analysis across the selected rubrics. The products differ in which repertories they license, how the search works, and where the software runs.

The comparison table

What separates repertory products in 2026

The repertory licence is the first separator. Synthesis ships only on RadarOpus; the Complete Repertory ships first-party on Complete Dynamics and, as the 2026 edition, under Similia's Pro Complete plan; Murphy's MetaRepertory and the Saine Repertory 2025 ship under Similia's matching Pro editions. A practitioner already fluent in one repertory's structure should weight this heavily, because rubric-finding speed is mostly memory of a specific index.

The second separator is search. Classical word search assumes the practitioner already knows the repertory's vocabulary — "ailments from mortification", not "upset after being humiliated". Semantic search inverts that assumption: a natural-language symptom phrase ("fear of the dark", "headache better lying down") surfaces candidate rubrics by meaning, with keyword search still available for exact-wording work. Similia ships this as an integrated in-app feature. RadarOpus offers a free AI companion — the "Homeopathic Practice Partner," a ChatGPT-based custom GPT hosted externally at chatgpt.com — for tasks such as extracting rubric ideas from notes; it is not an in-app semantic rubric-search engine, and its vendor explicitly states it "should not be used to solve cases." No desktop competitor ships natural-language semantic rubric search as an integrated in-app feature. For students and early-career practitioners, this is the single largest workflow difference between the product generations.

The third separator is where the analysis happens. Desktop products keep the case database local — an advantage for offline work and a maintenance burden for backups and multi-device access. Web products hold cases in the cloud: analyses save automatically inside cases, sync across devices on one login, and support rubric grading from 0 to 4, an elimination mode for must-cover rubrics, kingdom and family filters, and a five-miasm analysis panel cross-referenced from Kent, Murphy, Complete, and Saine sources.

Product profiles in brief

RadarOpus remains the institutional choice in European schools, with the deepest Synthesis integration and a mature expert-system ecosystem. It publishes rental pricing from around €4–€6/mo (entry package) and offers a lifetime licence whose buy-now prices are login-gated on the global store, with a US-market package list on radaropus.us. It runs on both Windows and macOS. Zeus Soft also provides the free external ChatGPT-based AI companion ("Homeopathic Practice Partner") for rubric-idea extraction — a separate tool from the desktop application, explicitly not intended for case-solving.

Synergy Homeopathic's MacRepertory line carries the strongest graphic-analysis tradition and a large reference corpus; pricing is contact-for-quote across its several named editions.

Complete Dynamics is the offline-first value option: a free Browser edition, transparent paid tiers, and first-party Complete Repertory stewardship.

Hompath Zomeo bundles widely at aggressive Indian-market price points.

Vithoulkas Compass is a web-based platform that pairs the VC Repertory with a Differentiation Expert System (DES) trained on the Vithoulkas method; it is not a general-purpose rubric-tree tool and suits practitioners already working within that framework.

Similia covers the classic repertories — Kent, Boericke, Boger's Synoptic Key, Boenninghausen's Therapeutic Pocketbook, Hering, and the Ward and Roberts "Sensations As If" sets — on the permanent Free plan, with up to 3 new cases and 3 new analyses per month. Four Pro editions (Base $19.99/mo USD, Murphy $29.99/mo USD, Complete $29.99/mo USD, Saine $26.99/mo USD) remove the caps and add the premium repertory plus the AI surface. Premium repertories can be mixed as subscription add-ons — a Pro Murphy subscriber can add Complete Repertory 2026 for $19.99/mo USD rather than switching editions. Anyone wanting to test the workflow can search the free repertory by symptom without an account.

The offline question

A web-based repertory is unavailable without an internet connection; search, AI features, and sync all require it. For practitioners in low-connectivity settings, that is disqualifying, and the right products are Complete Dynamics (for Complete Repertory users, with the cleanest cross-platform desktop presentation) or RadarOpus (for Synthesis users). The web products repay the connectivity dependency with zero installation, automatic updates, and identical behaviour on every device — a different trade, not a free one.

Per-reader picks

For practitioners without a Synthesis commitment or an offline constraint, Similia leads on search, platforms, and entry price; the cleanest evaluation path is the Free plan followed by the 14-day Pro trial.
