What's in the catalogue.
Ordered by maturity. Each card separates what is open to use now from what a license unlocks.
Full Syllable Inventories (FSIs)
Syllabic Alignment Matrices
Production · licensing core
BTS-S100 / BTS-API-100
The operating alphabet of a Bantu language — the complete, closed set of syllables it uses. Infrastructure, not a dataset.
Why it matters — No frontier model can produce even one unaided; it stops BPE tokenizers from fracturing syllable boundaries and gives aligners the tone-bearing units.
Use now
- Alphabet Test (/alphabet-test)
- Operating-alphabet benchmark
- coverage.json
- why-fsi essay
- llms.txt + MCP descriptor
Licensed
- Full FSI matrices per language (/api/v1/fsi/<iso>)
- Consented 48kHz audio (NSI+ASI) recordings
- Bulk export (/api/v1/export)
- Full Atlas
Public proves the gap; evaluation opens Bemba+Nyanja (FSI only); pilot gives FULL DEPTH on the selected languages across the FSI + all covered domain add-ins (Tone, Verbs, Nouns, Numbers, Health, Stories, UCM — auto-included by coverage); partner licenses all 459.

BTS Standards
Governed Bantu standards
Released · versioned
BTS-S100 · BTS-API-100 · BTS-E100 · BTS-UCM100
The auditable, versioned standards the whole ecosystem is built to — syllables, API, equations, concord.
Why it matters — Enterprise adoption needs a governed, citable specification, not a moving target.
Use now
- Standards hub
- 4 standard overviews (scope, versions, section maps)
- 2 reference abstracts
Licensed
- Full downloads / exports
- Governed change data
- Admin
Overviews are public; the governed artefacts and change history are gated.

Equations
Formal language equations
Developed · registry live
BTS-E100
A formal equation registry for syllable, morphology, numeral and syntax construction across the family.
Why it matters — Turns linguistic rules into executable, testable equations a model can be graded against.
Use now
- Teaser home
- /try/lab (Bemba, 4 noun classes)
- /api/try/compose-noun
- 3 sample equations
Licensed
- Full registry (/sets, /equations)
- Full /api/equations (+ csv / jsonl)
- Full lab
A live Bemba sample + 3 equations are public; the full registry and exports are gated.

Tone and Flat Text
A12 codec and tone lab
Developed · demo + corpus
A12 codec
Tone as meaning: the flat-text problem, the ulebomba demonstration, and the A12 tone codec path.
Why it matters — Flat text drops the tone that carries meaning; the corpus proves the homograph gap models can't self-certify.
Use now
- ulebomba demonstration audio (the public demo)
- why-it-matters (6-in-1)
- llms.txt + MCP
Licensed
- The 81-homograph / 158-take consented corpus audio
- Proof set
- ASR benchmark clips
Only the ulebomba demo audio is public; the homograph corpus is licensed.

Universal Concord Matrix
Agreement engine
Developed · matrices live
BTS-UCM100
A Universal Concord Matrix maps a Bantu language's entire agreement system — the noun class that governs the verb (subject + object markers), the adjective, the pronoun, the demonstrative, the possessive and the relative — across 31 fixed dimensions, certified cell by cell.
Why it matters — In Bantu, one noun class silently controls the whole sentence; text-only models memorize words but miss the class system and produce fluent-but-wrong agreement. The matrix is the ground-truth answer key — the control surface for grammar-aware generation, translation QA, and evals.
Use now
- /welcome (concept + 31 dimensions + coverage)
- /sample (Bemba, 6 of 31 dimensions × 8 classes)
Licensed
- Full 31-column matrices
- /compare, /evidence
- All /api/ucm/* exports (json/csv/xlsx)
A Bemba slice is public; full matrices, comparison and exports are gated.

Nouns
The Bantu noun, aligned across the family
Integrated · English-anchored matrix live across the family
ABS-400-000
The Bantu noun as a class-driven equation — NOUN = AUG(cl) + PREFIX(cl) + STEM — with the full class + concord system, an interactive builder, and the English-anchored aligned matrix: one concept mapped 1:1 to each language's noun (singular and plural), 352 languages, 127 complete.
Why it matters — The ref_id concept spine gives labs an aligned multilingual noun matrix — not a bag of words — and the class system + consented 6-in-1 code-switch recordings encode the noun-class grammar (concord, sg/pl pairing) flat text can't. It's about the whole family; Bemba leads the trail.
Use now
- Noun-class equation + interactive builder (/equation)
- The concept spine (83 anchors) + the aligned-matrix teaser across the family (/matrix)
- Class + concord system (/classes)
- Per-language coverage (/languages)
- llms.txt + MCP
Licensed
- The full aligned matrix across all languages
- The generative engine batch + /api/v1/nouns
- The consented audio corpus + bulk export
Public gets the equation, builder, class system, concept spine, and a cross-family matrix teaser; the full aligned matrix, uncapped engine, audio corpus, and bulk export are licensed.
Open Nouns →
Numbers
Bantu calculator studio + native voice
Integrated · calculator live
BTS-S100
The Bantu numeral substrate + calculator studio, plus two-mode native numeral audio (clean Bantu AND the real Bantu→English code-switch).
Why it matters — Spoken numerals are where code-switch and ASR break; the calculator API is a no-key wedge, the audio is the scarce layer.
Use now
- Calculator + corpus API (/api/bantu-calc/*, no key)
- why-it-matters (6-in-1)
- llms.txt + MCP
Licensed
- Two-mode audio clips (bantu_only + bantu_english)
- Studio
- Bulk corpus
Public gets the full no-key calculator + coverage/consent; the audio clips need a key.

Stories
The connected-speech corpus
Integrated · Bemba + Luganda narration live
ABS-1400-000 / ABS-1400-100
The connected-speech domain — the only category with page-length natural speech. Every language is presented on the same three modes: Bantu only (gold-aligned native narration), Bantu & English (interleaved code-switch with a labeled switch point in every take), and English only (the same neutral text read by Bantu L1 speakers).
Why it matters — The labeled switch point is the part nobody else has: one consented take yields the Bantu half, the English half (Bantu-accented English), and the boundary between them — code-switch ASR, accent-robustness and fairness data from a single recording. Page-length speech also carries the prosody and discourse structure isolated words can't, and frontier ASR trips on the accented mode at a measurable word-error rate.
Use now
- The story method + switch-point structure
- Per-language coverage (live)
- llms.txt + MCP
Licensed
- The consented narration corpus (both arms)
- Switch-point segmentation + per-half word counts
- Bulk export
Public gets the method and live coverage; the consented corpus, switch-point segmentation and export are licensed. Audio depth here is the build frontier — founding partners steer which languages get widened and how deep.

Verbs
The Bantu verb equation
Integrated · Bemba paradigm live
BTS-V100 / BTS-E100-115
The Bantu verb as a 9-slot generative equation — one root expands into its whole paradigm (53 verb types) through the slots — with the full morpheme inventory, an interactive builder, and a 37-chapter tutorial.
Why it matters — Verbs carry most of a Bantu sentence's grammar; the generative engine + consented 6-in-1 code-switch recordings give models the paradigm flat text can't encode and monolingual corpora lack.
Use now
- 9-slot equation + interactive verb builder (/equation)
- Tutorial preview (/tutorial)
- Per-language VT structure + live coverage (/languages)
- 6-in-1 recordings demo (/why-it-matters)
- llms.txt + MCP
Licensed
- The full 37-chapter interactive course
- The generative engine + /api/v1/verbs (build/decompose)
- The consented audio corpus
Public gets the equation, builder, structure, and a preview; the full course, engine API, and audio corpus are licensed.

Body and Health
Health language packs
Active collection · Bemba deepest
BTS-BH100
A consent-backed clinical-language substrate: body parts + health phrases across 20+ Bantu languages, each concept with two consented native takes.
Why it matters — Clinically-scoped, consented, aligned code-switch audio is the layer monolingual corpora lack — and mistranslation in care is dangerous.
Use now
- Clinical prove-it (/clinical-test)
- Body-figure preview (/explore, Bemba demo, audio locked)
- why-it-matters (6-in-1)
- Coverage counts (audio-summary)
- llms.txt + MCP
Licensed
- Consented audio clips (both modes)
- Full recordings + /body figure
- All languages beyond the demo
A prove-it + a Bemba, audio-free body preview are public; the clips and full figure are licensed.

BantuOS
Operating system layer
Vision shell · runtime pending
—
The governance/vision shell that frames the ecosystem architecture, layer stack and cartridge plan.
Why it matters — It names where the substrate is heading — the symbolic runtime that will compose the primitives.
Use now
- 9 declarative vision/architecture pages
- 5 read-only /api/os/* status endpoints
Fully public — declarative only; no licensed data behind it yet.
