If you searched for Cara homeopathic software, you are looking for a program that is no longer sold. Cara (Computer Assisted Repertory Analysis) was David Witko’s 1980s repertory for the Royal London Homeopathic Hospital. Cara Professional followed in the late 1990s. The line then became ISIS, then ISIS Vision, then Vision — Miccant’s current desktop repertory. Similia does not appear on that SERP today; this page is the Cara-shaped door into a browser alternative.
ISIS is mentioned here only as the successor name in that lineage. We do not ship an ISIS URL.
Disclosure: I'm the founder of Similia. I've tried to be even-handed below — corrections welcome by email.
TL;DR — Cara vs Vision vs Similia
Cara is discontinued. You cannot buy a new Cara licence. Old installs may still run on a machine that has not been upgraded; they are not a 2026 product.
Vision (Miccant) is the living desktop successor. Vision version 2 is listed at £389 lifetime (Windows or Mac) as of August 2026, with book add-ons extra. The dedicated comparison is Vision homeopathy vs Similia.
Similia is web-based, with a free forever classical tier and Pro plans from $19.99/month.

What Cara was
David Witko began digitising Kent for PCs in the early 1980s at the Royal London Homeopathic Hospital. That program became Cara. Cara Professional was the late-1990s expansion. In 2003 the line was reborn as ISIS, later ISIS Vision, later shortened to Vision (“for obvious reasons,” in Miccant’s own historical note). Witko was appointed a Fellow of the UK Society of Homeopaths for that work.
Cara mattered because it was early, hospital-tested, and British. It does not matter as a shopping SKU in 2026. If a forum thread still says “get Cara,” the practical question is Vision (if you want that desktop lineage) or a browser platform (if you do not want another orphaned installer).
What succeeded Cara
Miccant’s current repertory is Vision version 2. Combined Repertory plus a listed classical set ship in the box; Complete, Saine, Murphy, and materia medica titles are add-ons. There is no Miccant browser suite and no advertised AI assistant. Full library list and the £389 breakdown: Vision vs Similia.
We mention ISIS only so searchers who remember that name know it is the same family. We do not publish an ISIS product URL.
What is Similia?
Similia is a cloud-native homeopathy platform. The free tier includes seven classical repertories, 21 classic materia medica books, semantic search, and basic case management capped at 3 new cases and 3 analyses per month. Pro unlocks unlimited cases, the AI toolkit, and premium repertories (Murphy, Complete Repertory 2026, Saine).
No USB dongle. No Cara-era installer. Safari, Chrome, or a phone browser.
Side-by-side
Can I still buy Cara?
No. New purchases in this family are Vision plus optional books. Second-hand Cara discs are unsupported nostalgia.
Desktop lineage vs the browser
If you loved Cara’s one-click UK desktop feel, Vision is the continuity product. If what you actually need is Kent-plus-cases that will still open after the next OS update, Similia is the free homeopathic software path: no binary to orphan.
AI
Cara never had it. Vision does not advertise it. Similia ships semantic search on Free and named AI tools on Pro.
When Vision (the Cara successor) is the better choice
- You want the Miccant desktop lineage and a published sterling lifetime price.
- You already think in Combined Repertory + optional Complete and will buy books as add-ons.
- Offline native Windows or Mac is non-negotiable.
When Similia is the better choice
- Cara is gone and you do not want another desktop licence that an OS upgrade can break.
- You want 21 classic MM books and seven classical repertories without a book basket.
- You want AI tools Vision does not sell.
- You want to start at $0 and only pay if Pro earns its keep.
Verdict
Cara was important. It is not for sale. Vision is the honest desktop successor; read Vision vs Similia if that is the comparison you now need. Similia is the browser alternative: repertory software, a free classical tier, patient records, and the rest of the feature set without a 1990s installer.
