OpenBookLM

OpenBookLM is an AI knowledge workspace for iPad that connects to an Obsidian Vault or document folder so you can search, ask questions, read, and translate your notes.

Gather your notes, study materials, research documents, meeting records, drafts, and personal archives in one place, then ask questions. OpenBookLM finds relevant documents in your connected Vault and shows supporting references with its answers. You can go beyond the answer and open cited documents directly to review the original context.

This update adds a consistency review feature to help you find conflicting content inside your Vault. You can choose a basis file or folder, check for opposing settings and content, save review results, and clear them when needed. Vault-based answers can also warn you when conflicting information is detected in the referenced materials.

Key features:
- Connect an Obsidian Vault or document folder
- Vault-based search and AI Q&A
- View references and citations for each answer
- Open cited source documents from answers
- Vault consistency review and conflict history management
- Basis file/folder-based conflict review
- Search by document title, path, tag, or folder
- View document outlines and original text
- Edit Markdown and text documents
- Translate documents and create new translated files
- Save translations as Markdown or text
- UI support for Korean, English, Japanese, Spanish, German, and French
- AI answers matched to your selected language
- Supports Apple on-device Foundation Models, OpenAI-compatible API, Local API, and ChatGPT Browser connections
- Try quickly with the Demo Vault
- Layout optimized for iPad portrait, landscape, and split view
- Improved external Vault folder access when using the iPad app in Mac compatibility mode

Supported file formats:
Markdown(.md, .markdown), Text(.txt), PDF(.pdf), RTF(.rtf), Word(.docx), EPUB(.epub), HWPX(.hwpx)

Markdown and text files can be edited in the app. PDF, RTF, DOCX, EPUB, and HWPX files are used by extracting text for search, references, questions, and translation workflows.

OpenBookLM works around the Vaults and document folders you explicitly select. When using external folders such as iCloud Drive or Desktop, the app checks whether the selected folder can be accessed and guides you to reconnect if permissions are unavailable.

If you experience any issues or have improvement ideas, please let me know. I will review them carefully and reflect them as quickly as possible.
