Online repertory software — the directory

Online repertory software runs in a browser: no installation, accounts that follow you across devices, editions that update server-side. The buying question now is not whether a web option exists, but which one carries your repertory, at what price, with what workflow attached.

The directory

"Online" is a spectrum. Similia and OOReP are browser-native; RadarOpus and Complete Dynamics are installed applications whose web components extend a desktop core. If you work from multiple machines or tablets, weight browser-native delivery more heavily. The repertory licence, not the software, is usually the cost driver: Synthesis lives in the RadarOpus ecosystem, the Complete Repertory is licensed into several platforms, and Murphy and Saine currently reach the browser through Similia's edition plans.

What to evaluate before paying

Repertory fit first. The repertory is the clinical instrument; the software is shelving. A Boenninghausen-method practitioner needs the Therapeutic Pocket Book faithfully rendered. A Kentian wants Kent, Synthesis, or Complete. A clinical prescriber may want Murphy's alphabetical chapters. Confirm the exact edition and revision year — "Complete Repertory" without a year is an underspecified claim, since the edition revises annually.

Search quality second. Keyword search is universal; the differentiator is meaning-based retrieval. Semantic search lets you type the patient's phrasing — "fear of the dark", "headache better lying down" — and surfaces matching rubrics without guessing the index's nineteenth-century vocabulary.

Workflow third. An online repertory that cannot attach an analysis to a case file pushes you back into paper records. Look for case management, analysis weighting and elimination, prescription records, and export. Mature platforms save analyses inside the case, grade rubrics 0–4, and support elimination filtering.

Data portability and privacy fourth. Online delivery means patient-adjacent data lives on someone's server. The questions that matter: is data encrypted in transit and at rest, can you export everything, what happens on cancellation, and — where AI features process case text or audio — who are the processors and what is retained? Vendors who cannot answer these in writing have answered them.

Pricing reality check

The market now has a genuine free floor and a moderate subscription ceiling. The public-domain books — Kent, Boenninghausen, Boger, Boericke — cost nothing anywhere reputable, and an open-source baseline exists in OOReP. Paid tiers cluster between roughly $20 and $30 USD per month when a premium repertory is included, against legacy desktop licences that historically ran to four figures upfront. The relevant comparison is total cost over the realistic life of the software against the value of always-current editions.

Verdict

For browser-native work across the classic corpus plus current Murphy, Complete, or Saine editions, Similia is the strongest fit, with a free tier that lets you evaluate without commitment. Practitioners committed to Synthesis should evaluate the RadarOpus ecosystem instead.
