How Jev Powers Chem Autocomplete
ChemIllusion's post on how its structure autocomplete works: RDKit builds and checks every candidate from your drawing, and Jev picks which checked cards to show and in what order, in one request of about 0.2 seconds.

Highlights
- RDKit builds and checks every candidate structure from your drawing before anything reaches the model.
- Jev, a decision model from TypeSafe, picks which checked cards to show and in what order they appear.
- The selection runs in one request of about 0.2 seconds, per the post.
Watch out
Grounding is two sentences of page text captured on 2026-10-15, the post's introduction, with no meta description in the digest, so details beyond the RDKit-plus-Jev division of labour and the request time, such as benchmarks, pricing, model versions or a byline, were not available.
Questions about this entry
Short answers drawn from the linked project or page.
A feature that suggests the next structure while you draw, described in a ChemIllusion blog post. Candidates are built and checked before anything is presented, and the ordering of the suggested cards is a model decision rather than a chemistry computation.
RDKit builds and checks every candidate structure from your drawing, and Jev, a decision model from TypeSafe, then picks which of those checked cards to show and in what order they appear.
No. The post assigns building and checking to RDKit; every candidate is already verified before the model sees it. Jev's role is choosing among the checked cards and ordering them for display, which keeps chemistry validity with RDKit rather than the model.
About 0.2 seconds for the selection request, per the post. The capture gives no latency breakdown between the RDKit computation and the Jev call.

No byline appears in the captured text; the post is published on the ChemIllusion blog at chemillusion.com, with 2026-09-25 in its URL slug.
The capture does not say. Only the description of how Jev powers the autocomplete is recorded, with no repository, licence or API details.
