How Papira works — and what to expect

A short field guide. Read it once so you know whether your papers fit, what you are paying for, and when we will refund you.

What Papira does

Papira reads your research papers and builds a Coverage Matrix: the problems they tackle, the approaches they propose, the benchmarks they evaluate against, and the gaps between them.

It is not a summarizer, a citation manager, or a writing assistant.

What kind of papers work best

Papira is built for empirical research papers — where you can name a problem, an approach, and an evaluation with benchmarks or metrics.

Strong fit

A problem the paper solves
An approach the authors propose
Evaluation with benchmarks, datasets, or metrics

Not optimized for

Pure theory (no empirical evaluation)
Position papers, opinion pieces, essays
Literature reviews and surveys
Humanities without comparative methods
No explicit benchmarks or quantitative results

Most of CS, ML, NLP, systems, databases, robotics, computational biology, and quantitative social science fit this shape.

What you get

A Coverage Matrix across your uploaded papers
Identified gaps and contribution opportunities
Choose a map size: Discover (up to 5 papers, $9), Position (up to 10, $19), or Survey (up to 30, $49)
Your first matrix is free — up to 5 papers · 20 pages per paper
Pay per map · no subscription

What we cannot guarantee

Papira uses large language models to read and structure your papers. LLMs are probabilistic:

Two runs on the same paper may differ slightly
Unusual structure or ambiguous writing can produce extractions you disagree with
The “right” gap is partly subjective

Refunds

We refund in exactly two situations:

Technical failure

If Papira fails to deliver a Coverage Matrix — crash, empty output, or error before a result — we refund in full, automatically. If nothing arrives within 7 days, email help@papiraflow.com.

Charged but no service

Duplicate charges, billing errors, or paying for an analysis you never received. Email us; we fix it.

Disagreement with extracted problems, approaches, or gaps
Quality concerns when papers fall outside supported types above
Wanting different output than what was produced
Buyer’s remorse after viewing the result

FAQ

How many papers can I upload?: Up to your map tier: 5 papers (Discover), 10 (Position), or 30 (Survey). Need more? Talk to us.
Papers longer than 20 pages?: The limit is 20 pages per paper. Trim or split longer PDFs before uploading.
Languages?: English only, for now.
Share with collaborators?: Yes. The output is yours.
How is this different from ChatGPT reading my papers?: Chatbots do not build a comparable matrix, surface gaps systematically, or extract benchmarks in a queryable form. Papira does one job consistently.
How does pricing work?: Pay per Coverage Matrix, not per paper. Discover $9 (5 papers), Position $19 (10), Survey $49 (30). Your first matrix is free. No subscription.
Student pricing?: Your first matrix is free (up to 5 papers). After that, Discover at $9 is the student on-ramp. No subscription.
