ChatNest by Idzi

ChatNest lets you organize conversations from your favorite AI assistants into folders — directly inside the chat interface, without switching to any external app.

Supported platforms:
•Claude (claude.ai)
•Gemini (gemini.google.com)
•ChatGPT (chatgpt.com)
•Perplexity (perplexity.ai)
•Mistral / Le Chat (chat.mistral.ai)
•DeepSeek (chat.deepseek.com)

Key features:
•Nested folders with drag & drop — organize conversations into any folder structure you need
•Conversations moved to folders are hidden from the main list, keeping your sidebar clean
•Notes — add a short note to any conversation so you remember what it was about
•Unread markers — mark conversations to review later
•Pinned conversations — keep important chats at the top regardless of folder
•Color-coded folders — assign a color to each folder for quick visual identification
•Sort conversations — alphabetically (A–Z or Z–A) inside each folder
•Breadcrumb — see which folder the current conversation belongs to
•Archive — hide folders you no longer need without deleting them
•Export folder as Markdown — get a neat list of links with notes
•Export / Import — back up your folder structure as a JSON file
•Undo (Ctrl+Z) — reverse the last action
•Resize the panel — drag the left edge to your preferred width
•Light and dark theme
•English and Polish interface

Sync: All folder data is stored via Firefox Sync (browser.storage.sync), so your folder structure is automatically available on every device where you're signed in to your Firefox account.

What's new in 1.4.0
New features

Rename conversations directly in the panel — independent of the platform's own title (inline edit via button or double-click, undoable with Ctrl+Z)
Unread badge on collapsed folders — shows count of unread conversations including subfolders
Drag conversations between folders inside the panel — not just from the sidebar
Auto-sync conversation titles — panel titles update automatically when renamed on the platform; manually renamed titles are protected
Storage usage warning — yellow toast at 80KB, save blocked with error toast at 100KB (Firefox Sync limit)
Version number displayed in Settings tab

Improvements

Full English/Polish i18n with auto-detection from browser language; language can be changed in Settings
Default theme changed to light, default language to English
Toast notifications replace blocking browser alerts for storage warnings
URL validation before navigation — protects against malicious URLs in imported JSON files
Code fully refactored into modules (CN.i18n, CN.platform, CN.state, CN.ops, CN.render) — no functional changes, better maintainability

Bug fixes

Enter key handler now correctly resets between panel rebuilds — no more cases where the setting silently stopped working
Pinned-only conversations (not assigned to any folder) are no longer incorrectly hidden from the sidebar
