Changelog
PDF highlights, export menu and sign-in
Features
- PDF materials switch between "original PDF" and "parsed text": click a citation and it jumps to the right place in the PDF and highlights the passage.
- The workspace "···" menu was tidied up: a leaner view menu, plus a new export-by-type entry (sharing and exporting covers every material type).
- The library gained system folders for LLM conversations and agent sessions, with a "usage guide" shortcut.
- Google sign-in works end to end and WeChat QR sign-in is back; if an email already exists, you can sign in with the password you just typed.
- A bilingual Terms of Service page, plus machine-readable /llms.txt and /pricing.md.
- A product overview plus four new articles; article bodies now render tables, figures and code blocks, with a copy button.
Improvements
- Organize plans show progress (create folders, move files) and keep their state across refresh and history.
- The English site shows the local amount PayPal actually charges; upload progress shows a real percentage instead of stalling at 10%.
- Material titles in import notices are now links that open the material in the workspace.
Fixes
- Citation numbers out of range, silent tool failures, and original files stuck on a spinner.
A new deck engine, graphs, and the blog
Features
- Deck generation moved to a new pipeline, ppt-master: pages render in parallel, and an 8-page deck went from 649s to about 200s with the same quality gate.
- Decks can be edited by hand, or revised one page at a time with one sentence — every other page is preserved word for word.
- Knowledge graph: cross-material linking can be re-run per material with visible progress, backfills a folder or everything at once, and clicking a node highlights its immediate neighbourhood.
- A new "LLM chat" tab in the sidebar and a calendar view; conversation search now covers message bodies and highlights keywords.
- The blog shipped: article list, article pages and this changelog.
Improvements
- Graph extraction got more than twice as fast (a 20k-character material went from 31s to 9s).
- Collapsing the left pane keeps the icon rail; a refresh restores where you were (conversation, calendar month, graph range).
- Fonts load locally so the first screen no longer waits on a font served from abroad; the PDF icon shrank from 28KB to 7.1KB.
Fixes
- One material failing to parse no longer takes the whole graph down; failed turns are not shown as completed.
Deck templates, more formats, steadier parsing
Features
- Deck templates: upload your own pptx and generation reuses its colours and fonts; when a template lacks a layout it degrades instead of failing.
- Steadier uploads and parsing: several materials parse at once, stuck jobs are reclaimed, and scanned PDFs are recognised in parallel shards with page-level progress and pages filled in.
- Drag to reorder the library (folders and materials alike) or drag materials into folders, and the order sticks.
- Imported conversations render as rich-text bubbles on the note page, with 13 display bugs fixed; code blocks are light background, dark text, with syntax highlighting.
- Save icons added for Zhipu Qingyan, Tencent Yuanbao and Grok.
Improvements
- Very long materials are stored in partitions instead of being truncated away.
- Answers follow the language you write in, not the interface language.
- Upload and preview progress bars show real progress and no longer fake a fill when the total is unknown.
Fixes
- Decks with a swapped template lost their layout; switching materials could corrupt the body; large files timed out while parsing.
Deck style families, editable export, sharing
Features
- Deck generation gained "style families": pick a family, then swap themes within it.
- Exported HTML copies can be edited in the browser and saved back to the original file (one authorisation on first save).
- Public sharing now covers every material type — conversations, agent sessions, notes, files, audio and video; data backs up to a ZIP.
- Archives expand on upload and backups restore in one click; mind maps run end to end from generation to a library material you can edit.
- Membership expiry reminders by email.
Improvements
- Exports follow the interface language; deck export matches what you see on screen (fonts, line height, layout).
- Deleting a material or folder no longer leaves stray files taking up space.
- Brand name spelling and CJK/Latin spacing unified across the site.
Fixes
- Share links occasionally 404ed; mind maps failed on long materials; exported SVGs would not open and nodes would not collapse.
English added, PayPal, and free credit
Features
- A bilingual site shipped (Simplified Chinese / English) with a language switcher.
- PayPal payments alongside WeChat, and members can top up extra credit.
- New users get bilingual welcome documents on their first visit.
Improvements
- Pricing set to ¥15 / ¥40 / ¥132, with a 14-day trial and ¥5 of credit; the member page shows credit and expiry.
- The workspace opens faster (editor and graph load on demand).
- Deck and PDF previews moved to pdf.js, fixing black and blank screens; scrollbars hide until you scroll.
- Uploads are capped at 128MB with an early warning when you pick a file.
Fixes
- Uploads over 2MB failed on mobile networks; home page copy and footer wording disagreed.
Native agent actions, and mobile
Features
- Native agent actions: ask in plain language to save an answer as a note or to organise files; tool calls get their own cards with per-tool icons.
- AI messages can be edited in place or regenerated; conversation history pages in, and a saved-note card survives when you look back.
- WeChat sign-in and sign-up shipped; @-mentioning a material no longer needs a leading space; microphone failures explain themselves and can be re-authorised from the icon.
- Account usage breaks down tokens by model and by day; external agents (an AI inside your editor, a command-line tool) can read and write your library, with install scripts for Windows, macOS and Linux.
- The library supports dragging materials into folders, nested folders and pinning; the workspace gained micro-interactions (pane collapse, message entry, button feedback).
Improvements
- Thinking traces render as Markdown with an animation while you wait; reply font size, block spacing and tool-card density were redone.
- Fixed a lag in the input box that re-rendered the whole chat pane on every keystroke.
Fixes
- Follow-up questions are no longer injected as a repeat of the previous turn; read-only views stopped showing a pointless notice.
The library, and editing in place
Features
- The library became one tree: folders and materials together, with nested folders, pinning (remembered on the server), tags and drag-to-file.
- Edit a material inside the conversation: per-block suggestions you can accept or reject, each with its reason; paired quote marks merge into one revision, halving the clicks.
- Materials and folders use model logos and file-type icons; folder rows gained a "···" menu and a context menu (new file, new subfolder, rename, pin, delete).
- A ⌘K command palette; ⌘⇧F / Ctrl⇧F focuses the search box.
- The home page was rewritten around three pillars with interactive demos (ask about a file, revise suggestions in place).
Improvements
- Very large materials open in milliseconds instead of seconds; list and detail split with skeletons.
- Pane corners and collapse animations tightened up; reply font size and spacing unified.
Fixes
- Pinned order was overwritten by the sort rule, the list flickered on refresh, and edit-suggestion bubbles could not be clicked.
Parsing, citations and search
Features
- Web link import: titles and bodies are fetched, images render, and the dialog closes itself when the import finishes.
- Parsing expanded a lot: Word, Excel, image OCR, PDF layout reconstruction and scanned pages; decks parse into structured HTML with slide previews.
- Cited answers: markers are clickable, ranges like [A-B] expand, and clicking jumps to the matching spot in the material.
- Search overhauled: live dropdown, bodies included, multiple snippets with highlighting and jump-to.
- The first layer of the knowledge network (automatic linking plus a full-screen graph), and quick capture notes.
Improvements
- Q&A moved to a new model engine, on by default, with an automatic fallback when it fails.
- Switching materials no longer blocks saving and shows loading feedback; search requests gained a timeout so they cannot spin forever.
Fixes
- Titles and bodies could get out of sync when switching materials; search could hang on "searching" indefinitely.
Materials, and a new workspace
Features
- Import PDF, Word, Excel, PowerPoint and web links.
- Selected passages join the conversation as context; paragraph-level AI suggestions can be accepted or rejected in place.
- Voice input; "/" shortcut menus in both the editor and the chat box.
Improvements
- A new AI chat pane: tool-call cards, copy and stats, with browsable history.
- Overall layout and interaction polish.
A new workspace skeleton
Features
- The workspace moved to a new three-pane skeleton: materials on the left, content in the middle, AI on the right.
- Uploaded materials parse automatically, and you can ask about a single selected material.
Improvements
- Note folder collapse state is remembered.
Fixes
- Occasional false "you are signed out" prompts.
v1 released
Features
- Notes gained nested folders; conversation titles can be renamed, and the layout is more flexible.
- Compare two notes line by line.
Improvements
- Markdown preview background set to white.
- Switched to the release version and went public (v1).
Filling in the site
Improvements
- The home page and its hero were redone.
- Company, business and product pages filled in; the footer tidied up.
- The site moved to a light theme; the company logo appears in the browser tab.

- Password reset; the email field fills itself in after verification.
- Body font is configurable; rich text became the default editor.
Improvements

- Invitations, and annotations on selected passages.
Improvements
- Privacy and about pages; a proper tab title and icon; payments went live.
Fixes
- The word cloud stopped rendering.
Membership, payments and a data panel
Features
- A member page (two columns), plan and order modules, QR payment and automatic navigation after paying.
- Order history and subscription expiry management; email verification on signup.
- A data panel: conversation and note counts, a word cloud, word counts, unread badges.
Improvements
- Saving a note is faster; feedback can be sent straight to our inbox.
Fixes
- Broken export and sharing, note dragging, search still filtering after clearing the box.
Rich text, and the first launch
Features
- Rich-text notes, and rich text became the default editor; columns move, items get context menus.
- Right-click a conversation to create a note from it.
- Qwen and Hunyuan added to collection.
Improvements
- Notes save automatically; the site went live publicly for the first time.
Page skeleton and dragging
Features
- Pages link to each other directly, with a shared top bar; the login page was rebuilt.
- Notes pin and drag to reorder; a link can open a specific conversation.
Improvements
- Lists show placeholder skeletons while loading; your conversation grouping preference is remembered.
Fixes
- Markdown rendering, and the note rename field.
Notes get their own column
Features
- Notes split out of the workspace (new, save, rename, menu) with search.
- Conversations can be grouped by criteria.
Improvements
- The divider between notes and workspace drags to resize; empty lists explain themselves.
Fixes
- Duplicate notes, content scrambling on refresh, messages lingering when switching conversations.
Six platforms, one library
Features
- Collection covers six platforms: DeepSeek, Doubao, Wenxin, OpenAI, Gemini and Kimi.
- Collected pages lay out as AI left, user right, preserving the original formatting; the note column splits into collected and notes.
Improvements
- Platform icons in lists and previews, with links back to the original chat.
The first version
Features
- The three-pane workspace took shape: list left, notes middle, chat right.
- The browser extension was built alongside the web app, uploading collected chats straight into your library.
Improvements
- Markdown preview and editing, click-and-drag text reorganisation, export and download, autosave.
- Search worked — being able to find things came first; sharing and sign-up shipped alongside.

AskLLM-notebook: turn a YouTube video into material you can question
YouTube has whole courses on it, but video is linear: to find the sentence the instructor said ten minutes ago you drag the scrubber and hope, and there is nowhere to ask about the part you did not follow. LLM-notebook turns a YouTube link into material you can question — the video plays in the workspace, the subtitles are laid out by paragraph, and anything you do not understand you select and ask about. Answers cite the exact passage, and one click jumps back to that moment.
Read postCollectLLM-notebook: turning flowing LLM conversations into knowledge assets
A sharp answer in ChatGPT, a workable engineering practice in Gemini, reusable reference material in Qwen — and a week later it is scattered across four chat histories, impossible to search and impossible to edit. LLM-notebook collects LLM conversations into one library and settles them into notes you can read, export and share.
