What has shipped.

First public release. The full critical-edition workflow, from

• Multi-witness workspace — compare up to eight witnesses in resizable, synced panes, with per-pane image filters (brightness, contrast, gamma, rotate) and a deep-zoom OpenSeadragon viewer.
• Upload pipeline — drag-and-drop PDF, TIFF, image, and plain-text ingest with direct-to-R2 uploads; the server never touches the file body.
• OCR for 10+ scripts — Tesseract.js runs in your browser for Arabic, Greek, Latin, Syriac, Hebrew, Coptic, Ethiopic, Persian, Ottoman Turkish, and Old English, as resumable jobs with progress that survives a reload.
• Witness metadata and citations — repository, shelfmark, date, material, hand, and script-style fields, with one-click SBL, Chicago, and MLA citation output.
• Line-locked alignment and variant clustering — anchor passages across witnesses; cluster-based readings emerge automatically, in ECM/NA28 style, with orthographic normalisation rules.
• Lexicon hover across traditions — Sefaria, Perseus, Scaife, CAL, Sedra, Coptic Scriptorium, QAC, Lane, Steingass, and Bosworth-Toller, with per-source attribution and graceful degradation.
• Translation tracker — confirm word links across witnesses and see every rendering of a term at once.
• Notes at four levels — project, witness, anchor, and word, in Markdown.
• Editorial conjectures and section divisions — record conjectures and structure the edition into chapters and sections with a sigla legend.
• Stemma codicum — neighbour-joining over cluster signatures, exportable as Newick and print-ready SVG.
• Publication-grade export — TEI Parallel Segmentation, LaTeX with reledmac, plaintext apparatus, JSON, CSV, sigla legend, stemma SVG, and Newick.
• Sample projects and onboarding — curated starter editions (including a four-witness John 1:1–5) and a first-run tour.
• Search and analytical tools — cross-witness search, frequency analysis, and collation summaries, plus a dedicated workspace for authoring the critical introduction.
• Gothenburg-model auto-alignment — sub-line span alignment that propagates across line breaks, computed in a Web Worker so the editor stays responsive.
• AI image enhancement (Pro) — Real-ESRGAN super-resolution for damaged regions of a scan.
• Accounts and billing — Clerk sign-in, a Free tier you can do real work on, and a single $12/month Pro plan via Stripe.
• Accessibility — keyboard navigation, focus management, and a WCAG pass across the marketing site and workspace.
