Read detailed guideGuide the AI toward specific terminology in your field. Custom instructions help capture domain-specific terms, proper nouns, and concepts that matter most for your index.
Navigate and understand your generated index using the powerful viewer tools.
Explore your index with the dual-panel interface. The left panel shows your full index organized alphabetically or by AI-detected groups, while the right panel displays detailed information about each term including all page references and cross-references.
Click any page number to instantly view the source text where a term appears. The text viewer highlights your term in context, making it easy to verify extractions and understand how concepts are used throughout your document.
Switch between two viewing modes: Index mode shows curated, professional-quality page references, while Concordance mode reveals every AI-detected mention for comprehensive coverage. Perfect for deciding which references to include in your final index.
Read detailed guideShape your index with powerful editing tools for merging terms, adding relationships, and organizing content.
Master the fundamental editing operations. Merge duplicate terms to consolidate references, create "see" and "see also" cross-references to guide readers, and organize terms into parent-child hierarchies with subentries.
Manually add terms that the AI may have missed. Enter single terms, batch import multiple entries, or upload a CSV file. Indexia automatically checks for deleted terms and offers to restore them instead of creating duplicates.
Edit multiple terms at once for efficient index refinement. Select terms using the multi-select interface, then apply bulk operations like merging, adding cross-references, or creating subentries across your selection.
Indexia automatically detects semantically similar terms and groups them together. Use groups to quickly identify terms that might need merging, cross-referencing, or reorganization. Collapse and expand groups to focus on specific areas of your index.
View and manage all relationships for a term in one place. See incoming and outgoing cross-references, parent-child connections, and AI-suggested relationships. Accept or reject suggestions to build a well-connected index.
Automatically identify and remove less significant terms to meet your target index size. The AI analyzes term importance based on mention frequency, relationships, and semantic significance, then suggests which terms to cut while preserving the most valuable entries.

Read detailed guideQuestions and workflows that have come up from professional indexers using Indexia on real book projects. Each entry is a short answer to a specific real-world question.
To decide whether to keep an entry, demote it to a subentry, or remove a page reference, you often need to look at the actual page.
Click the term in the index so its entry box appears in the left panel. In the entry box, click the page number. A Full Text popup opens with that page in plain text. The term is highlighted; scroll if you need to find it.
Caveat: the popup shows reading-order text extracted from the PDF, not the visual page layout. Definition boxes, figure captions, and other floating elements often appear at the bottom of the page rather than where they sit in the PDF.
Publishers usually want lowercase entries; AI extraction sometimes produces title case.
Double-click the term name in the left panel (or in Index View). Type the corrected form. Enter saves; Escape cancels. This updates the standardized display name only — the raw text in the source document is not altered.
It is worth scanning the index after generation specifically for casing inconsistencies, since they tend to be systematic rather than one-off.
The right-click menu in Index View and Graph View is faster than the hover buttons on a term box, but it is less forgiving.
Right-click → Delete executes immediately, with no "Confirm Delete?" intermediate step. The hover-button delete on a term box in Graph View requires a second click within 1.5 seconds to confirm.
Right-click deletions are still recoverable via Restore Deleted Terms in the toolbar, but if you tend to use the right-click menu, treat each click as committing the action.
Some subentries have no detach control — they're labeled "contextual" in the entry box and the broken-chain icon is missing.
Two kinds of subentries exist. Hierarchical (referential) subentries are ones a user created by linking a term as a child of another — these can be detached anywhere. Contextual subentries are auto-generated by the AI from the parent term's mention contexts during indexing, and they are managed by the AI grouping system. They have no detach control by design.
Workaround: open the contextual subentry's Subentries popup and re-link it to its current parent. The conversion converts it from contextual to hierarchical. After that the broken-chain icon appears and detach works normally.
A common cleanup move: pull a narrow term out of the top-level alphabet and nest it under a broader one.
Click "additive bilingualism" in the index so it appears in the left panel. Hover over its entry box; a Subentries button appears at the bottom-left. Click it.
In the popup, select "bilingualism" as the target term. Default direction: the term you clicked (additive bilingualism) becomes the parent, and the term you selected (bilingualism) becomes the child. That is the reverse of what you want, so click the Swap button to flip the relationship.
Click Convert. "additive bilingualism" now appears indented under "bilingualism."
Reverse of the move above.
Click the child term to bring its entry into the left panel. Hover the entry box and click the broken-chain (Detach) icon mid-left. The term becomes a top-level entry again.
This only works for hierarchical (referential) subentries. See "Why can't I detach this subentry?" for the contextual case.
Deleting a subentry outright would lose its mentions. There is a two-step workaround.
Hierarchical subentries keep their own mentions separate from the parent's mentions, so simply deleting the subentry also deletes those pages. To preserve them on the parent:
Step 1: Detach the subentry (broken-chain icon). It becomes a top-level term, carrying its mentions with it. Step 2: Find that newly top-level term in the index and Merge it into the original parent. The detached term is deleted and its mentions transfer to the parent.
Example: "variegated babbling" as a subentry of "babbling" → detach "variegated babbling," then find it under V in the index and merge it into "babbling."
Publishers typically recommend no more than five page references per entry. AI extraction will often over-include.
Review each entry's page list and remove pages where the term is mentioned in passing rather than elaborated. Example: a chapter introduction listing topics will trigger a mention for each topic, even though only the body of the chapter actually develops them.
To remove a single page: select the term, expand its entry box via the box-with-arrow icon at the top-right, then click the trash can next to the page reference. Each page is its own mention. To remove a span like 84-86, you delete page 84, then page 85, then page 86 individually.
To collapse a series with gaps (e.g., 154, 156, 159) into a clean range (154-159) when the term is genuinely covered across that span, double-click the page list and type the range manually.
Manual addition runs a text search across the document for the new term and creates mentions automatically. If no mentions are found, the term still gets created — you just need to add pages by hand.
Toolbar → Add Terms → Add Terms Manually → type the term → click the green Add button. Indexia searches the document for the term and adds any pages it finds.
If the search finds nothing relevant, the term is still created but won't appear in the index until it has at least one page. Add pages manually by double-clicking the page list (or, in Graph View, using the + button next to the page list).
Real example: a user added "vocal tract, infant and adult" expecting the search to fail. It did. They then manually added pages 59-60, and the term appeared in the index.
Some line-layout and punctuation refinements are easier to do after export than in the editor.
For fine punctuation control (specific commas, semicolons, hanging indents to publisher spec) and rare line-break decisions, finish the structural edit in Indexia first, export to Word (.docx), and do the polishing pass in your downstream word processor.
