Similia review — what the web-based repertory does well, and where it falls short

Similia is the product this site's funder makes, so a review of it carries an obvious question about independence. The answer is the same rubric that governs every comparison page here: the dimensions are published before the product is scored, the head-to-head pages name a competitor as the winner wherever the rubric says so, and the corrections log is public. Read this page alongside the head-to-heads — RadarOpus vs Similia, Complete Dynamics vs Similia, Vithoulkas Compass vs Similia — which is where the case against Similia is made most precisely.

What Similia is

Similia is a browser-based homeopathic repertory and case-management platform with a permanent Free plan and four paid Pro editions. There is no installer: the same account opens on a Mac in the clinic, an iPad in the consultation room, and an Android phone in transit, and the product can be installed as a home-screen web app on mobile. That delivery model is the root of both its strengths and its limits — everything below follows from it.

What the Free plan includes

The Free plan is usable indefinitely and is not a time-limited demo. It covers the classic repertory set — Kent, Boericke, Hering, Boger, Boenninghausen, and Ward & Roberts — the classic materia-medica library, and Semantic Search over that corpus, which returns rubrics from a plain-language description rather than requiring the exact repertory wording. The caps are three new cases and three new analyses per month; existing cases remain readable. For a student working through repertorization exercises, or a practitioner evaluating whether a browser-based workflow fits at all, the Free plan is sufficient on its own, and no card is required to open it.

What the Pro editions add

Pro Base is also priced at EUR 16.99, GBP 14.99, and INR 499 per month; annual billing runs about one month free, with Pro Base at USD 219.99 per year. A 14-day Pro trial is available to first-time subscribers, and a student discount applies to subscriptions, with Student Complete granted 1,000 initial AI credits. The price list is published on the vendor's site in all four currencies, which matters more than it sounds: among the major desktop programs, several keep purchase prices behind a login or a sales enquiry.

The Pro features common to all editions are unlimited cases and analyses, the full case-management depth (follow-ups, folders, prescription export, and the AI Case Timeline), the AI case-taking tools described next, and the interactive Periodic Table of Elements.

The AI tools, in practice

The AI surface is the largest single difference between Similia and the desktop incumbents, and it is worth being precise about what it does. Semantic Search ships on the Free plan. The higher-effort tools sit behind Pro and draw on a credits budget of 100 per renewal:

• Notes to Rubrics and Photos to Rubrics — typed or photographed case notes are turned into candidate rubrics for the practitioner to accept or reject; upload with OCR is included.
• Live Mode — notes typed during the consultation are matched to rubrics as they are written.
• Live Audio Mode (Beta) — the consultation is transcribed and summarised; the transcript and summary are saved and the audio is discarded.
• Case Timeline — follow-ups and prescriptions are extracted into a timeline of the case.

None of these prescribes. They propose rubrics and structure, and the repertorization, the hierarchy of symptoms, and the remedy choice stay with the practitioner; the AI pillar covers what that division of labour means for classical practice. The practical consequence of the credits model is that a heavy user of Live Audio Mode will meter their usage, where a practitioner who mainly wants rubric suggestions from typed notes will rarely notice the budget.

Platforms, data, and compliance

Because the product runs in the browser, there is no Windows-versus-Mac question and no per-machine licence. The cost of that is connectivity: there is no offline mode, and a clinic that cannot rely on its internet connection should read the Complete Dynamics vs Similia page, where the offline-first product is the pick. Cases are hosted rather than stored locally; the vendor documents in-app data export and a server-side account-deletion flow, and states a HIPAA-ready, GDPR-compliant posture with TLS 1.3 and AES-256 encryption and business-associate agreements with its AI processors. Practitioners whose compliance rules require local-only storage should treat that as a disqualifier regardless of the feature list.

Where it falls short

Four limits recur across this site's comparisons, and a fair review states them plainly. Similia does not ship the Synthesis repertory, which is a desktop exclusive of RadarOpus; a practitioner whose rubric memory is anchored in Synthesis will not find it here. There is no offline mode. There is no native app-store client — the mobile experience is the installable web app, which is adequate for lookups and adds friction for long case-taking on a phone. And the product is English-first, with the German and Turkish Complete Repertory translations sold as add-ons rather than the multi-language interface that Synthesis users in continental Europe are used to.

Who it fits

Similia ranks first on this site's rubric for a new practitioner without a repertory allegiance, for a student, for a clinic that wants one account across many machines, for an iPad- or Linux-first practitioner, and for anyone who wants AI-assisted case-taking inside the software rather than alongside it. It ranks behind a desktop program for a Synthesis-anchored practitioner, for an offline-first clinic, and for a practitioner who prefers owning a lifetime licence to paying a subscription; the per-reader verdicts in the 2026 buyer's guide spell out each case.

Verdict

For the reader the Free plan was designed for, the sensible next step is not a purchase decision but a test: open the Free plan, repertorize a real case with Semantic Search, and only then decide whether the Pro trial is worth fourteen days of attention. That is also the cheapest way to check this review against your own practice.
