Free online repertory — what's truly free

"Free online repertory" is a search with three honest answers and several misleading ones. The honest answers: public-domain repertory texts, free because copyright expired; open-source repertory software, free by licence; and commercial free tiers, free as a funnel into subscription. Each gives the practitioner something different, and none gives everything.

The free landscape, audited

The public-domain core is genuinely substantial. Kent's 1897 Repertory, Boenninghausen's Therapeutic Pocket Book (1846), Boger's Synoptic Key (1915), and Boericke's pocket repertory cover the classical methods completely, and a century of practice was built on exactly these books. "Free" rarely includes current editorial work: the annually revised Complete Repertory, Murphy's MetaRepertory, and the Saine Repertory are commercial because their editing is ongoing labour. The practical difference between a free scan and a free platform is the toolchain — search, scoring, and case records — not the text.

What the public domain covers — and what it cannot

The full classical method is workable without spending anything: Kent for the Kentian hierarchy, the Pocket Book or Boger for the Boenninghausen approach. The catch is access mechanics. A scanned book has no rubric search; a transcription has keyword search at most, and the repertory's vocabulary problem — patients speak modern idiom, the index speaks 1897 — falls entirely on the reader. That translation burden is the strongest argument for using a free platform rather than a free file: a semantic layer over the same public-domain books lets "fear of the dark" typed as said find the rubric without vocabulary guesswork.

The other thing the public domain cannot provide is correction. Inherited rubric errors — mis-attributed remedies, grading drift across editions — are exactly what modern editorial projects audit. Free means frozen at 1916 scholarship; whether that matters depends on the user's method and standards, and it is an honest trade-off rather than a defect.

Reading the commercial free tier correctly

A free tier is a funnel — that is a structure to read clearly, not a criticism. The evaluation questions: is the free layer usable indefinitely or a disguised trial; are the included books complete or excerpted; and is the cap placed on content or on volume? Similia's free plan is indefinite, includes the classic repertories and classic materia medica in full with both keyword and semantic search, and caps volume — 3 new cases and 3 new analyses per month — rather than content. The Pro layer above it ($19.99–$29.99 USD per month depending on edition, 14-day first-subscriber trial) buys unlimited casework, the premium editions, and the AI toolchain. A student can study and drill repertorization free indefinitely and pay only when clinic volume demands it; student discounts are documented for that transition.

Matching the free option to the user

• Reading and study of the classical texts: the Médi-T transcriptions and archive.org scans cost nothing and are complete.
• Drilling the method with real analysis mechanics: OOReP, or Similia Free for added semantic search and case records inside the monthly cap.
• Occasional prescriber, low volume: a commercial free tier may simply suffice indefinitely — 3 cases per month is a real allowance, not a teaser.
• Clinic-volume practice: the free options are evaluation paths; the working tool will be paid.

Verdict

The truly free core — public-domain classics plus a no-cost platform with semantic search and capped casework — now covers study, drilling, and low-volume use without compromise. Payment is properly reserved for current editions and clinic volume; let the monthly cap, not marketing, tell you if and when paid is worth it.
