What it is
ANNIS is an open source, cross platform, web browser-based search and visualization architecture for complex multi-layer linguistic corpora with diverse types of annotation, designed to provide access to data from a variety of projects and linguistic phenomena.
Gabriel’s notes
ANNIS is an open source, cross platform (Linux, Mac, Windows), web browser-based search and visualization architecture for complex multi-layer linguistic corpora with diverse types of annotation. ANNIS, which stands for ANNotation of Information Structure, was originally designed to provide access to the data of the SFB 632 – Information Structure: The Linguistic Means for Structuring Utterances, Sentences and Texts. It has since then been extended to a large number of projects annotating a variety of phenomena. Since complex linguistic phenomena such as information structure interact on many levels, ANNIS addresses the need to concurrently annotate, query and visualize data from such varied areas as syntax, semantics, morphology, prosody, referentiality, lexis and more. For projects working with spoken language, support for audio / video annotations is also required. Data is often annotated using both automatic taggers/parsers and a growing set of manual annotation tools (e.g. EXMARaLDA, ELAN, annotate/Synpathy, MMAX, RSTTool, Arborator, WebAnno, Hexatomic), ANNIS provides the means for visualizing and retrieving this data. Pepper is used to import the multiple annotation formats into ANNIS. For detailed information on the latest version of ANNIS see the User Guide under documentation
Good fit if you want to:

Pricing snapshot (auto-enriched): Free and open source; no pricing or usage limits mentioned.
Work-use / compliance snapshot (auto-enriched): ANNIS is an open-source linguistic corpus tool without publicly documented workplace compliance features such as SOC2, HIPAA, GDPR, SSO availability, or specific data handling and retention policies, making it likely unsuitable for regulated enterprise environments requiring these certifications.
Alternatives (auto-enriched): Alternative: AntConc | Comparison: AntConc is a desktop freeware tool focused on concordancing and text analysis, while ANNIS is a browser-based platform supporting complex multi-layer linguistic annotations and multimedia integration.
