Changelog

[3.3.3] - 2026-07-22 (versionCode 21)

Added

• Summarize a scan: a Summary chip next to Translate condenses an AI scan into Short, Medium or Detailed form. Summaries stay in the document's own language, keep numbers and dates exactly as written, and are cached per length — switching between the summary and the full text is instant and costs nothing. Copy, export, print and edit all follow whichever view is on screen

[3.3.2] - 2026-07-22 (versionCode 20)

Added

• Export filenames suggested from the text: exports are named after what the page actually says instead of always being Scanned Document, and the name stays editable before saving. Works offline, for both OCR and AI results
• Arabic word spacing: the Arabic model emits a space at only some word boundaries, so clean paragraphs came back with words merged. Spaces are now rebuilt from the gaps between recognized letters

Fixed

• Arabic pages read as gibberish: a photographed Arabic page could be read as confident Latin or CJK nonsense, and the old retry only triggered when most lines failed outright — so a confidently-wrong page was never retried. Verified on 28 real documents: 6 broken pages recovered, 21 byte-identical
• Sideways and upside-down pages: the first pack to clear the score floor decided the flip, so a pack scoring its own nonsense could turn a page over before the pack that actually reads that script got a vote. Every pack votes now
• Doubled letters in mixed Arabic/Latin text: "Repost" no longer comes back as "RRepost"
• Location barcodes: a geo: barcode opened a browser error page instead of a map
• Permanent AI cooldown: leaving the screen mid-cooldown froze the countdown forever, and the rate-limit sheet kept appearing until the app was force-stopped
• Product lookup when offline: every source failing now reads as an error instead of claiming the barcode is in no database
• Scan history saves moved off the main thread — they stalled the results screen and crashed outright on a full disk
• Launcher icon: showed a plain white tile instead of the pink gradient

Changed

• Settings rebuilt on M3 Expressive groups: connected rows 2dp apart, large radii on the group ends and small ones at the joins, with a spring corner morph while pressed. Settings, Look & Feel and Text Recognition now share one primitive. AI Providers collapses each provider to a row that expands into its form on tap
• Denser script picker: single-line subtitles, an aligned right edge, and a much quieter selection tint — the list was reading as a stack of tall, heavy cards
• Kotlin 2.4.10, up from 2.3.21
• CodeQL now scans for vulnerabilities on its own workflow, separate from the Quality Gate

[3.3.1] - 2026-07-16 (versionCode 19)

Added

• Longer PDF scans: AI Scan now reads up to 20 pages of a PDF, up from 3

Fixed

• Product lookup: a product missing from Open Food Facts now reads "not found" instead of "Errors: HTTP 404" — v3 answers an absent barcode with a 404, which was being treated as a failure

Changed

• One request per scan: up to 5 images now travel in a single request instead of one request each, and a PDF goes to Mistral OCR whole rather than a request per page — several times less free-tier quota per scan
• Per-provider page limits: a scan is trimmed to what the provider documents (5 on Groq and Cerebras, 1 where the cap is undocumented) and the result says so, rather than being split across requests or rejected outright
• AI Scan picks one PDF at a time; the image picker now takes 5

[3.3.0] - 2026-07-14 (versionCode 18)

Added

• Barcode scanner controls: pinch-to-zoom and tap-to-focus, with the scan box lifted clear of the controls
• WYSIWYE exports: exports now match the preview you see on screen
• New launcher icon and a full-resolution splash logo

Fixed

• Scan history: a corrupt scan_history.json no longer wipes every saved scan
• Custom AI endpoints: no longer crash the app or leak API keys
• Arabic OCR: pages are read the right way up and embedded Latin words are preserved
• AI Scan: stopped requesting camera permission it never needed
• Model downloads: continue when you leave the Settings screen
• AI providers: the required fields for each provider are now stated up front

Changed

• Open Food Facts: migrated to API v3
• Startup and packaging: single-ABI packaging, lazier startup, LUT tensor normalization

[3.2.0] - 2026-07-12 (versionCode 17)

Added

• Offline OCR engine: PaddleOCR PP-OCRv6 via ONNX Runtime (detection, recognition, classification, layout) — pure Kotlin, no key, no network
• Markdown results view: Original/Markdown chips and a Compose renderer for tables, headings, emphasis, lists, checkboxes, code and quotes; printing via the system dialog
• Exports: Word (.docx), Markdown and JSON alongside PDF and CSV, saved to Downloads/Scanly
• ZXing barcode engine and content parser
• New launcher branding, provider logos, and a NOTICE file for attribution

Fixed

• Provenance-gated markdown detection; copy/export/print/edit now consistent with the visible view
• WebView print leak; print rendering moved off the main thread
• Escaped-pipe and unmatched-marker parsing in the Markdown renderer

[3.1.3] - 2026-07-09 (versionCode 16)

Added

• Real provider logos in the AI Providers screen — brand wordmarks tinted in each provider's color, replacing the generic Material glyphs

Security

• Personal API keys are now encrypted at rest. Keys you type in (OpenRouter, Gemini, OpenAI, Claude, Mistral, Hugging Face, NVIDIA, Groq, Cerebras, Cloudflare, custom) were stored as plain text in the settings DataStore and were eligible for Android Auto Backup. They are now encrypted with AES-256-GCM backed by the hardware Keystore, and the settings file is excluded from cloud backup and device transfer. Keys saved before this change still work and are upgraded to ciphertext on next save.
