Changelog

✨ New features

• Authorship Certificate — Open the Process Timeline panel in the editor (⌘⇧P) to see your verdict (Green / Yellow / Red) and behavioral metrics. Generate a signed PDF with QR code and a public verification URL anyone can open in any browser.
• Plagiarism inline actions — Highlight any matched passage to Rewrite (academic paraphrase via diff-overlay), Cite (prefills the citation picker with the source URL or DOI), or Exclude (dismiss for this session).
• AI Check inline highlights — Severity underlines on AI-detected regions; opt-in auto-humanize for Red verdicts; score-improved compare banner after a Humanize → re-scan loop.
• Citation hover preview & drag-and-drop — Drag any URL or DOI into your document to open the citation picker; hover any citation to preview metadata without breaking flow.
• Cowriter Plan mode — Ask the agent to plan an edit; approve the steps; then Pause / Resume during execution. Each step's diff lands one at a time.
• Get Started checklist — Track your first document, first Cowriter session, first grammar check, first citation, first referral — auto-hides when complete.

🛠 Improvements

• Settings, simplified — Unified into a single modal with 8 tabs: Account, Editor, Invite, Interface, Hotkeys, Security, Billing, Notifications.
• Notification bell — Tabs / archive / snooze; inline action buttons (e.g. Snooze 1 day / Snooze 1 week) handled server-side.
• Sidebar credit badges — Tier Boost pill with days-left countdown + bonus-words counter; click → Billing.
• Toast priority pipeline — Critical toasts stick until acknowledged; high-priority TTL doubles; low-priority floods coalesce.

🐛 Fixes

• Authorship verdict no longer penalises short, hand-typed sessions with no adverse signals.
• Cite-from-plagiarism now correctly prefills the picker with the source URL.
• Document autosave no longer flags an empty new doc as "title too long".

• Breadcrumbs — navigate nested folder structure with clarity

🛠 Improvements

• Document load time — faster opening for large documents
• Editor shortcuts — new keyboard shortcuts in the writing surface

✨ New features

• Quality tiers — Choose Fluent ⚡ (fast, free), Smart ✦ (balanced, Spark), or Native 🎯 (top quality, Pro) per task. Translate, paraphrase, grammar, plagiarism, and Cowriter all respect your choice.
• Provider transparency — A small "via vendor · model · ms" pill on every AI panel shows which model handled your request, so you always know what you're getting.
• Auto-failover — If your primary AI vendor degrades, Diglot quietly retries through your tier's backup chain. You'll never see a half-broken response.
• Health probes — Every model is auto-tested every 5 minutes; deprecated models are disabled automatically.

🛠 Improvements

• Faster cold-start — Route resolution now hits a Redis cache; first AI call after page load is noticeably snappier.
• Cleaner error envelopes — When a tier isn't available on your plan, the upgrade prompt explains exactly what's locked and what unlocks it.
• Better prompt management — Per-tier system prompts mean Smart and Native genuinely behave differently, not just route to a different model.

🐛 Fixes

• Resolved a race where two parallel requests could compete for the same routing rule.
• Fixed a fallback loop that occasionally picked the same broken vendor twice.

✨ New features

• Cowriter chat panel — Multi-turn conversation that reads your document and proposes edits via a green/red diff overlay. Accept, reject, or auto-accept each change.
• Agent tool registry — Cowriter can translate, scan grammar, paraphrase, humanize, check plagiarism, find citations, and apply edits — all from inside the chat, no panel-switching.
• Inline composer (⌘K) — Press ⌘K anywhere in the editor to ask for a change at the cursor or on a selection. Pasted external text triggers an "Integrate" chip so Cowriter can blend it in for you.
• Sessions sidebar — Search past Cowriter conversations with full-text search; pin, archive, duplicate, or rename sessions; group by Today / Yesterday / This week / Earlier.
• Auto-titles — New sessions get a sensible 3–7-word title generated automatically (no more "New conversation").

🛠 Improvements

• Anchor-drift recovery — Cowriter edits still resolve even if you keep typing while the agent is thinking (up to ±200 chars of drift).
• Tool-event chips — A small running/✓/✕ indicator strip shows you what the agent is doing in real time.
• Better paste detection — Cowriter notices when you paste a chunk of external text (≥100 chars) and offers to integrate it.

🐛 Fixes

• Diff overlay no longer leaves stale decorations after rapid Accept/Reject.
• Fixed a session-list flicker when switching documents.

✨ New features

• Plagiarism preview — Sample-based originality check that returns in seconds. Full async scans available on demand for larger documents.
• AI Check — Detect likely AI-generated regions in your document, with per-region severity scoring and a clear verdict.
• Humanize — Rewrite AI-flagged passages to sound more natural; side-by-side compare shows exactly what changed.
• Cowriter agent tools — Plagiarism check and AI detection are now first-class agent tools, so you can ask "is this passage original?" right in chat.

🛠 Improvements

• Smarter language detection — Three-tier strategy (Unicode script → curated short-word dictionary → franc-min for longer text) means short greetings like "Hola" / "Bonjour" / "Hallo" finally classify correctly.
• Faster paraphrase — Academic mode response time cut roughly in half.
• Grammar suggestions tuned for ESL writers (less false-positive on bilingual phrasings).

🐛 Fixes

• AI Check now reacts to live editor updates (was previously stuck on the document state at panel-open).
• Resolved an edge case where Humanize would lose paragraph breaks on very long passages.

✨ New features

• Citations from URL or DOI — Paste a link or DOI; Diglot fetches metadata across Crossref + Semantic Scholar (deduplicated) and inserts a properly formatted citation.
• Auto-rendered bibliography — Insert the BibliographyNode block once; it stays in sync with your inline citations as you add or remove them.
• Template catalog — Pre-built templates for academic essays, cover letters, statements of purpose, business emails, research summaries, and more.
• Slash menu — Type / anywhere in the editor to insert headings, lists, citations, templates, or AI commands without taking your hands off the keyboard.
• Citation styles — Switch between APA 7, Chicago 17, Harvard, and MLA 9 with one dropdown — your whole document reformats.

🛠 Improvements

• Cleaner editor surface — New decoration stack ordering means highlights from Plagiarism, Grammar, and Cowriter no longer overlap visually.
• Faster federated lookup — Citation search now hits Crossref and Semantic Scholar in parallel, deduping by DOI / normalised title.

🐛 Fixes

• Resolved a layout glitch in the Templates panel on tablet-width screens.
• Citation popovers no longer trap focus on dismissal.

✨ New features

• Bilingual editor — Type in your strongest language or in English; Diglot translates as you go and keeps both sides in sync.
• Translator panel — Word, sentence, and paragraph translation with a reverse-check that warns you when the output drifts in meaning.
• Grammar checker — ESL-tuned grammar that understands the patterns non-native English writers actually fall into (article omission, false friends, register slips).
• Paraphrase — 10 modes: academic, business, simple, formal, casual, expand, shorten, persuasive, friendly, neutral. One-click rewrite of any selection.
• Translation memory — Diglot remembers your past translations and reuses them automatically across documents.
• Glossary — Curate domain terms once; Diglot honours them in every future translation, paraphrase, and grammar suggestion.
• Documents — Local-first editing surface backed by autosave; documents survive accidental browser closes.
