Reconcile In-Text Citation Keys With Bibliography Entries — Free
A citation can be well formatted yet point to no bibliography entry. Count uses and entries under your own stable source keys to expose missing, uncited and duplicate identities before polishing style.
The proof surface
Citation-style checks inspect presentation conventions. This matrix reconciles source identity counts across two places, does not demand one entry for every repeated use, and cannot judge accuracy, authority or whether a citation belongs in the argument.

Sample, not your facts: Illustrative inputs: Smith2024 | 3 | 1; Rivera2023 | 2 | 0; Lee2022 | 0 | 1; Chen2025 | 1 | 2. Expected bibliography entries per cited key = 1. Stable source keys requiring a count check: 3 keys needing review. All records are invented.
Before using the citation-key matrix
Build a stable key list from the actual sources before counting. A key can be a private shorthand such as Rivera2023, but two different works by the same author and year need distinct keys in your working list. This tool does not parse a manuscript, citation manager export or bibliography file. Human counts are explicit so a learner can reproduce why a row is marked. The usual one-entry setting is an entered convention, not an enforcement of a particular style guide. Some assignments legitimately use an uncited reading list; a flagged unused key is then a question to resolve with the assignment instructions. The matrix is useful after drafting because citations and references often drift apart during edits, while a polished formatting pass can make that structural mismatch harder to notice.
Why the flat version breaks
Demanding an entry for every use
One source can be cited many times. Compare identity once with the expected entry count rather than multiplying entries by in-text occurrences.
Collapsing two works into one key
A shared author-year label can hide a missing reference. Assign distinct stable keys before counting to avoid a falsely reconciled row.
Calling zero flags a complete document audit
Only entered keys are checked. Omitted citations, wrong quotations and poor sources remain outside the count matrix.
How to work the citation-key matrix
Assign one key to one actual work
Use non-sensitive short labels and distinguish same-author same-year works. Duplicate keys across rows are rejected. A key is an identity aid, not a replacement for the complete source information in the document.
Count each side independently
Count in-text uses and bibliography entries separately. Repeated uses of the same source are allowed and do not require repeated bibliography entries. Keep counts as whole numbers; the app will not infer them from pasted prose.
Read the mismatch category
A cited key with fewer than the expected entries has a missing-entry gap; one with more has excess entries. An uncited key with entries is marked as unused. A key absent from both is neutral. The summary counts marked keys, not the sum of every citation occurrence.
Resolve against the assignment
Check the manuscript, source manager and current style or assignment requirements. Ask an instructor or editor if an uncited reading-list entry is intended. Reconciliation says nothing about quotation accuracy, evidence quality or plagiarism.

HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.
Citation-count reconciliation only, not source verification, plagiarism detection, grading or editorial approval. It does not inspect the manuscript or decide whether an uncited reading list is permitted. Check actual source identities and assignment requirements with an instructor or editor before submitting a document.
Data note: The citation-key matrix processes stable source key | in-text uses counted | bibliography entries counted locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.

What this is built on
Method: A cited key with fewer than the expected entries has a missing-entry gap; one with more has excess entries. An uncited key with entries is marked as unused. A key absent from both is neutral. The summary counts marked keys, not the sum of every citation occurrence.
All sample records, dates, quantities and labels are invented. No outside policy, contract, rate, clock offset, measurement or accessibility standard is represented as verified.
Google’s official pricing documentation, fetched 2026-09-30, says AI Studio is free in available regions. Optional formatting may require a Google account; manual local entry requires none. Limits can change and free-tier content may be used to improve products. Do not send private records.
Before: polished citation style could hide a missing source identity. After: repeated uses, missing entries and duplicate keys are separate count questions.
Smith2024 has three in-text uses and one bibliography entry, matching the entered one-entry convention. Rivera2023 is cited twice but has no entry; Lee2022 has an entry but no counted use; Chen2025 has two entries for one stable key. Three keys need review for different reasons. Three uses of Smith are not three missing entries. The stable keys are invented labels, not real publications or an automatically extracted citation audit.
Adding the missing Rivera entry, finding an actual Lee use and removing the duplicate Chen entry makes every row reconcile under the one-entry setting. These edited counts are an illustration; in a real document, do not add a citation that does not belong merely to clear a flag. Search the text and bibliography against your own stable key list and correct whichever source record was actually miscounted.
A scratch key absent from both places contributes no mismatch, while one cited key with one entry reconciles. The empty scratch row is visible and can be removed from the working list. It does not prove completeness: a citation omitted from the input altogether is invisible to the tool. This edge separates an explicitly checked absent key from an unreviewed part of the document, and keeps a neutral count from being presented as a successful full-document audit.
Optional AI formatting, never the calculation
Manual entry completes this citation-key matrix for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.
Format only these fictional or non-sensitive notes for a citation-key matrix. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string"]}], "setting": "string"}. The columns are stable source key | in-text uses counted | bibliography entries counted; the setting is Expected bibliography entries per cited key. Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.
An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
