Price: $12-199 vs $29+-499/mo
Doofinder positions as "more affordable Klevu/Algolia" — and really is on the market. Starter $29+/mo (~3-4× cheaper than Klevu). However compared to AI Search at same volumes, we cost 2-3× less.
On 10k SKU: $70/mo savings = $840/year. On 50k: $220/mo = $2,640/year.
Integration: native module vs API+JS
Doofinder: API + JS-layer
Doofinder has an OpenCart module, but inside it works through combination:
- Backend: your OpenCart server sends catalog to Doofinder API via cron
- Frontend: Doofinder JS-script intercepts search form and renders own UI over your theme
Pros: fast integration, mature product. Cons: result design is Doofinder UI; SEO for search pages limited (JS-rendered).
AI Search: native OpenCart module
OCMOD-installer. Subscribes to event hooks. Replaces only ID list — rest is OpenCart's twig.
Multilingual: both good, but differently
Area where Doofinder is traditionally strong — as Spanish product, has focused on EU multilingual from the start. On UA/RU/PL it works well (better than Klevu/Searchanise).
AI Search uses multilingual-e5-large-instruct — open-source model trained on 100+ languages in parallel. Our benchmark shows ~92.7% top-3 on Ukrainian houseware store 30k SKU.
| Language | Doofinder | AI Search (e5) |
|---|---|---|
| Ukrainian | good | excellent |
| Russian | good | excellent |
| Polish | good | excellent |
| Spanish | excellent (native) | good |
| German | good | excellent |
| Chinese | limited | good |
