Elicit vs PDFdigest

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors.

The short answer

Entry price: Elicit from $49/mo, PDFdigest from $2.50/credit — different billing units, so no direct winner
Free plan: Both have one
Public API: Elicit has one; not confirmed by us for PDFdigest
Higher Trust score: Elicit — 94 vs 57 for PDFdigest
Best fit: Elicit: Systematic reviews and evidence synthesis where every included paper needs the same fields pulled · PDFdigest: researchers wanting a fast narrated overview of a paper before reading it fully

What our research says

Elicit

Elicit is the only one of these tools that treats a literature review as a structured extraction job rather than a chat, which is exactly right for the work. The price assumes you are billing someone else for the hours it saves.

Pros

Column-per-field extraction into a table is the correct shape for review work and rare elsewhere
Free tier is unusually generous: unlimited search, summaries and full-text chat
Every claim links back to the paper it came from
API access is included from the first paid tier rather than sold separately

Cons

The $49 to $169 jump is steep and Scale is priced for institutions, not labs
Free tier's limits on the Research Agent and Reports are not quantified anywhere on the pricing page
Extraction accuracy still needs spot-checking against the source PDF
Coverage is paper-centric, so grey literature and preprint-heavy fields are thinner

PDFdigest

PDFdigest's niche is specific: hand it a research paper and get a narrated video summary back instead of a text digest, aimed at faster comprehension than reading the paper directly. Because the vendor's own site could not be reached during this check - it returned server errors on repeated attempts - the details here rely on secondhand listings and should be confirmed on the live site before relying on them.

Pros

produces a narrated video summary, not just a text digest
credit packs rather than a locked-in subscription
a small number of free daily credits for logged-in users, per third-party listings

Cons

the vendor's own site returned server errors on repeated fetch attempts during this check
company name and country could not be confirmed
credit-pack quantities per tier aren't clearly documented in available sources
