## Summary
Field linguists documenting endangered and Indigenous languages depend on annotation software. The dominant tools, ELAN and FLEx, date from the 1990s and fit poorly with workflows where a model proposes labels and humans correct them. Newer tools are numerous, but few have been assessed from a documentary linguistics perspective.

The authors gathered 98 annotation tools from prior surveys, documentation literature, community wikis, commercial platform listings, and ComputEL/LREC papers. They coded each tool against a 32-dimension rubric grouped into seven categories: cost, sustainability, portability, usability, ethical sensitivities, linguistic annotation capabilities, and active learning. Speech transcription tools were excluded. Coding relied on public documentation rather than hands-on testing.

The tools serving field linguists turn out to be very few. Morpheme-level glossing, collaboration, and machine-in-the-loop support rarely coexist in free tools. The paper offers a feature matrix, a short list of recommended free tools, and advice for developers. The rubric can also guide how future platforms, including LLM-era ones, are judged.

## Key points
- Of the 98 surveyed tools, 44 were both free and accessible for evaluation, while 32 could no longer be accessed.
- Of the 44 free tools:
  - 15 handle morpheme segmentation and glossing.
  - 6 of those also allow remote collaboration.
  - Only PACTE adds active learning, and it is closed-source.
- The Interlinear Text Editor in SIL FLEx remains the de facto IGT standard despite being desktop-only, offering little collaboration, and lacking active learning.
- INCEpTION cannot yet segment morphemes, but its open-source, plugin-based design makes it the most promising candidate for extension.
- The authors recommend that tool repositories be archived (e.g., Software Heritage) and that data be exported to interoperable formats such as EAF, LIFT/FLEXTEXT, or Ligt RDF. Stated limitations include no inter-annotator agreement statistics and reliance on self-reported features.
