Update on Claude Artifacts Import

Claude has modified how Artifacts are handled in their latest version.

I’m currently investigating to understand exactly what changed.

Unfortunately, version 1.3.0 of the plugin cannot properly import artifacts from the latest Claude archives: imported notes come through empty.

I’m working on a fix and will release version 1.3.2 ASAP. Stay tuned!

Nexus AI Chat Importer v1.3.2 Released - Critical Bug Fixes

Hi everyone! :waving_hand:

I just released v1.3.2 which fixes critical issues with Claude imports.

:counterclockwise_arrows_button: What Happened

Anthropic changed Claude’s export format without warning. The old format used tool_use blocks with name: 'artifacts', but the new format uses create_file and str_replace tool calls. This caused all Claude artifacts (code files, markdown, etc.) to be completely ignored in recent imports.

:bug: What’s Fixed

Critical Fixes

  • Claude artifacts now work with the new export format
    • All text-based artifacts (code, markdown, etc.) are now properly extracted
    • Binary files show as attachment callouts with proper links
  • Fixed crashes during import (missing logger errors in 9 files)
    • Prevents ReferenceError: logger is not defined crashes

Other Fixes

  • Fixed weird formatting in conversations with multiple attachments
  • Removed orphaned separators between messages
  • Fixed nested callout quote breaking
  • Better messages when re-importing conversations
  • Fixed ChatGPT research prompts incorrectly detected as DALL-E prompts

:inbox_tray: How to Get Your Missing Files Back

If you imported Claude conversations recently and noticed missing code files:

  1. Delete the affected conversations from your vault
  2. Re-import the same ZIP file
  3. Everything will be there now! :white_check_mark:

Nexus AI Chat Importer v1.4.0 Released - Le Chat, CLI, & Claude Improvements

Hi everyone! :waving_hand:

I’m excited to release v1.4.0 — a big update with a new provider, a CLI tool, and important Claude improvements.

:rocket: What’s New

:robot: Le Chat (Mistral AI) Support

You can now import your Mistral AI Le Chat conversations! The plugin handles attachments, references, and citations. Since Le Chat exports don’t include conversation titles, the plugin auto-generates one from your first message.

:desktop_computer: Command-Line Interface (CLI)

A standalone CLI tool lets you import conversations without opening Obsidian — useful for automation, large archives, or headless setups.

  • All providers supported: --provider chatgpt, --provider claude, or --provider lechat

  • Preview with --dry-run

  • Full feature parity with the plugin

Contributed by @caseyg via PR #33 :tada:

:file_folder: Human-Readable Artifact Folders

Claude artifacts are now stored in folders that match the conversation name instead of cryptic UUIDs.

  • Before: artifacts/a3663666-58a8-4835-bef1-308fb59c8609/

  • After: artifacts/2026-02-10 - My Conversation/

Existing UUID-based folders are renamed automatically on first launch, and all wikilinks are updated.

:triangular_ruler: LaTeX Math Conversion

\[...\] and \(...\) math delimiters are now automatically converted to Obsidian’s $$...$$ and $...$ syntax. Code blocks are left untouched.

:counterclockwise_arrows_button: Migration: Artifact Callout Restoration

Anthropic changed the structure of their Claude export format. Conversations imported with v1.3.x may be missing inline artifact callouts — even though the artifact files themselves were correctly extracted to disk. This is not a plugin bug, but a consequence of Anthropic’s export format change.

The v1.4.0 migration automatically detects affected notes and restores artifact links at the end of each note. To get artifacts positioned inline within messages, delete the affected note and re-import from your Claude export ZIP.

:bug: Bug Fixes

  • Multiple attachments in a single message no longer break out of the parent callout

  • Claude artifacts now render correctly for both old and new export formats

  • Conversations on mobile no longer show raw placeholder text instead of artifact links

  • Binary files referenced by Claude scripts are no longer saved as empty artifacts

Nexus AI Chat Importer v1.5.4 Released — Full UI Localization & Bug Fixes

Hi everyone! :waving_hand:

I’m happy to release v1.5.4, which bundles the headline feature from v1.5.0 — complete UI localization — with a series of bug fixes and polish updates.

:globe_showing_europe_africa: Full UI Localization (10 Languages)

The plugin UI is now fully internationalized and automatically matches your Obsidian interface language — no configuration required.

Supported languages: English · French · German · Spanish · Italian · Russian · Chinese (Simplified) · Japanese · Portuguese · Korean

Every dialog, settings panel, progress modal, and import notice is translated. Import reports and conversation note content remain in English to keep your vault content consistent regardless of language.

:bug: Bug Fixes (v1.5.4)

Le Chat — Generated Images
Assistant-generated images now display a clean “Not included in export” callout with a proper filename (generated-image.jpg) and a direct link to the original conversation, instead of a raw UUID path.

Missing Attachment Callouts — All Providers
All missing attachment callouts are now a single clean line across Le Chat, ChatGPT, and Claude:

:warning: Not included in export. Open original conversation

ChatGPT — Multi-ZIP Regression Fix
User-uploaded images were incorrectly marked as “Not included in export” when importing multiple ZIP archives simultaneously — even when the images existed in older archives. This regression is now fixed, restoring the behavior from v1.2.x.

Support Links & Branding
Support links updated to nexus-prod.dev, support box and donation messaging fully localized across all 10 languages.

Nexus AI Chat Importer v1.5.5

This is an important maintenance update for OpenAI users and anyone importing large archives.

1. OpenAI export structure change

OpenAI recently modified the structure of its conversation exports.
Conversation files are now split differently, and new exports are no longer compatible with plugin versions earlier than 1.5.5.

If you import recent OpenAI archives, updating to v1.5.5 is required.

2. Memory usage improvement for large archives

Until v1.5.4, archives were fully loaded into memory during import.
With very large exports, this created a potential risk of high RAM usage and possible crashes.

Version 1.5.5 improves the import process to significantly reduce memory pressure and eliminate that risk.

    • import summary

    • index heavy

    • index mobile

:wrench: Improved

  • Unified ZIP processing model on desktop and mobile (scan first, then targeted reads only)

  • Better handling for already-imported archives on mobile:

    • reprocess/recreate all notes

    • add/update missing or changed notes

  • First-install UX: Get Started now opens plugin settings directly

:bug: Bug Fixes

If you test this release, feedback is very welcome, especially for large ZIP imports and mobile behavior.

I’m building and maintaining this plugin without stable income, and currently dealing with health issues.
If the plugin helps you, support really makes a difference:

Hi Superkikim,
Thank you for the effort building this plugin. I am trying to use it but it was not working . I don’t really understand where (or If) I should initiated it.

I just set up the files and folders, as you mentioned in your guide but nothing happened afterwards. Is there any logs or any way for me to know what I’ve done wrong?
Thanks,
Nio

Hi,
I managed to find “+” icon button on the left to start the import. but Once I clicked it I got this error: “No supported archive was detected in the selected ZIP files”…

39

Hi @asets

What kind of zip file are you trying to import ?

This error messages is usually related to an unsupported provider or archive format.

Can you give a bit more context ?

40

Thanks Superkikim,
The file is a a Chat GPT back up created. I added a video so that you can watch and better understand why I am getting error: “No supported archive was detected in the selected ZIP files”…

42

Hey @asets

Thank you for the video. It’s a great way to share feedback. Very insightful, and it gave me ideas for new features.

I just hit the 1000+ bar for downloads of this release. Time to release a new one :wink:

Currently, from OpenAI, only ChatGPT exports are supported in the plug-in. I didn’t know yet OpenAI released an export feature as you showed. That’s great news.

Bear with me.

I’m currently working on 1.6.0, which will bring Perplexity support and some improvements. After that, I plan to work on additional features, and handling OpenAI exports is definitely something I want to implement. However, I can’t commit to a timeline. Sometimes things move quite fast; sometimes they take much longer. It all depends on my availability and on the complexity of the exercise.

Version 1.5.7, for example, was complex and long to release. Still I’m very proud of the memory-handling improvement I made. It was 100% worth it.
