The AI-in-homeopathy software buyer's guide
The AI-in-homeopathy software market in 2026 has one shipping vendor and several incumbents that have not entered it. Of the six products in active distribution, only Similia ships LLM-backed features as a first-class product surface — semantic rubric search, case-notes-to-rubrics suggestion, photo analysis, and live consultation transcription. RadarOpus, Synergy's MacRepertory line, Complete Dynamics, and Hompath Zomeo ship no equivalent in their current releases, and Vithoulkas Compass is an expert system in the older, rule-based sense rather than a language-model product.
The AI-capability table
| AI capability | Similia | RadarOpus | MacRepertory | Complete Dynamics | Zomeo | Vithoulkas Compass |
|---|---|---|---|---|---|---|
| Semantic rubric search (natural language) | Yes, on the Free plan | No | No | No | No | No |
| Notes to rubrics (text analysis) | Pro; AI credits | No | No | No | No | No |
| Handwriting OCR for case notes | Pro; AI credits | No | No | No | No | No |
| Photos to rubrics (image analysis) | Pro; AI credits | No | No | No | No | No |
| Live typed-note rubric matching | Pro (Live Mode) | No | No | No | No | No |
| Live audio transcription and SRP extraction | Pro, Beta; AI credits | No | No | No | No | No |
| Rule-based expert system | Miasm analysis panel | Vithoulkas Expert System add-on | Analysis strategies | Polar analyses | Analysis strategies | Core product |
The last row marks a real distinction. Expert systems predate the LLM era and remain useful, but they answer a different question: a rule-based system scores a fixed structured input against fixed weights, while a language-model surface interprets unstructured input — prose notes, speech, photographs — into repertory language.
What each AI feature does in practice
Semantic search is the entry point. The practitioner types the symptom as the patient said it — "headache better lying down", "fear of the dark" — and the system surfaces candidate rubrics by meaning rather than exact wording, with keyword search retained for exact-phrase work. On Similia this ships on the Free plan, which is the cheapest way to test the workflow against real casework.
Notes to Rubrics analyzes consultation notes and suggests rubrics, flagging Strange, Rare and Peculiar details; a selection mode analyzes only highlighted text, and an OCR path converts photographed handwritten notes to text first. Photos to Rubrics extracts symptom phrases from an image of a visible physical sign and maps them to rubric suggestions. Live Mode matches typed symptom lines to rubrics during the consultation, and Live Audio Mode (Beta) transcribes the conversation, extracts SRP symptoms, and adds matching rubrics at roughly one symptom per two-minute cycle, prioritising SRP over modalities, sensations, and locations, and avoiding generic rubrics. In every one of these flows the practitioner reviews and accepts or rejects each suggestion — the model proposes rubrics, the homeopath prescribes.
What it costs
AI features on Similia sit behind the Pro editions — Base $19.99/mo USD, Murphy or Complete $29.99/mo USD, Saine $26.99/mo USD, annual at roughly one month free — and consume AI credits: 100 credits are granted at each subscription renewal, students on Complete access receive 1,000 initial credits, and packs run from $14.99 USD for 200 credits to $49.99 USD for 1,000. Text and image calls are charged from model token usage; Live Audio also meters transcription minutes. Credit economics reward batch workflows — one notes-analysis per consultation — over exploratory clicking.
What AI in homeopathy cannot do
Three limits. First, suggestion quality is bounded by the repertory itself: the model maps language to existing rubrics, it does not generate clinical knowledge, and an inaccurate match is always possible — every suggestion must be reviewed before it enters the case. Second, AI is a workflow layer over the canon, not a clinical authority: faster repertorisation accelerates the path to a prescription but does not substitute for materia medica judgment or careful case-taking. Third, AI processing has a privacy surface: case notes, photos, and audio are processed by third-party providers. Similia documents a consent gate for AI processing, names OpenAI and Deepgram in its stack, states that Business Associate Agreements and zero-retention processing cover the data, and notes that audio recordings are not saved — only the transcript and summary. Any AI product worth using should disclose at exactly this level.
The incumbents' position
The desktop incumbents' absence from the table is a fact, not a prophecy. RadarOpus has the largest rule-based ecosystem — the Vithoulkas Expert System among them — and an obvious incentive to ship a semantic layer; Complete Dynamics has the cleanest cross-platform codebase to build one on. A practitioner who wants AI workflows today buys what ships today.
Per-situation verdicts
| Situation | Recommendation |
|---|---|
| Wanting AI-assisted repertorisation now | Similia Pro — the one shipping product in the category |
| Zero-cost test | Similia Free's semantic search |
| Offline-first practice | No AI option exists offline; Complete Dynamics for the desktop workflow |
| Vithoulkas-method practice | Vithoulkas Compass or the RadarOpus VES add-on — rule-based, not LLM |
| Privacy-cautious clinic | Similia Pro after reviewing the AI-consent and BAA documentation |
For language-model assistance in repertorisation the category has a single shipping occupant in 2026; the natural evaluation path is the Free semantic search at similia.io first, then the 14-day Pro trial.
