Common questions, fixes for known issues, and instructions for power users.
Android — fully supported, available on the Play Store now. Requires Android 10+ with at least 4 GB RAM for on-device AI.
iOS & macOS — in development. Join the waitlist via the landing page to be notified at launch.
Windows, Linux, and Web — planned for a future release.
No. There is no Mindverse account, no Mindverse backend, and no Mindverse server. Your notes never touch our infrastructure.
The only external connection the app makes is to your own Google Drive when sync is enabled — using your Google account, not ours.
Yes — fully. Notes, AI, transcription, tag generation, and Skills all work with no internet connection. Everything runs on-device.
Google Drive sync queues changes and uploads when connectivity is restored. YouTube and web link capture require internet at capture time.
Notes live in the app's private documents directory as plain .md files with YAML frontmatter. Images go in an images/ subfolder; audio recordings go in audio/.
A lightweight SQLite index powers fast search and sorting — but the Markdown files are the source of truth. The index can always be rebuilt from them.
Mindverse creates a mindverse/ folder in your Google Drive and syncs all notes, images, and audio there as plain files. Notes are stored as .md files — readable directly in Google Drive without any app.
Sync is ID-based: each note has a stable Drive file ID, so renames do not create duplicates. Sync runs automatically in the background after any change.
Yes — with a few requirements:
.md file inside the mindverse/notes/ folder in your Google Drive.YYYY-MM-DD-HH-mm-title.md format (e.g. 2026-05-01-12-00-my-note.md). Files with different names still import but may sort incorrectly.tags, category, created_at) will have their metadata preserved. Plain Markdown without frontmatter also imports fine — Mindverse will generate metadata on first sync.Deleting a note moves it to the in-app Trash. Notes in Trash are not immediately removed from Drive. They are deleted from Drive only when you permanently empty the Trash.
To keep a note in Drive but hide it from the app, archive it instead of deleting it.
No data is sent to any external AI service. All inference runs locally.
AI tasks have a built-in 2-minute timeout — after which the task is marked failed and the queue moves on.
Open the note, tap the three-dot menu, and select Reprocess. This re-runs tag generation and categorization via Gemini Nano.
To regenerate tags across all notes at once, enable Developer Mode and use Reprocess All Notes.
Transcription runs fully on-device. On a modern flagship phone, a 5-minute recording typically transcribes in 30–90 seconds.
Image paths in the index are absolute. After reinstalling, the app's documents directory path changes, breaking those references.
mindverse/images/ in your Drive.Deleted notes go to Trash first — they are not permanently removed immediately.
If the note was already permanently deleted from Trash, check your Google Drive — the .md file lives in Drive's own Trash for 30 days before Drive removes it permanently.
Yes. Every note is a plain .md file. Open the mindverse/notes/ folder in your Google Drive as a vault in Obsidian, or any other editor. Edits made outside the app sync back in on the next sync cycle.
Duplicates can appear if the same note was created on multiple devices before sync was enabled, or if the index lost track of Drive file IDs.
Usually an OAuth token expiry issue.
If the issue recurs, check whether Android's battery or data settings have restricted background network activity for Mindverse.
Auto-trigger skills join the background processing queue after save — they will not fire instantly if the queue is busy.
The notes are almost certainly still on disk — the index likely got out of sync during the crash.
Relationships are built incrementally as notes are processed. After a bulk import or index rebuild, they may not yet be computed.
Enable Developer Mode and tap Rebuild Relationships. This runs across your full library and can take a few minutes. Once complete, related notes will appear on each note's detail view.
v1.0.0) 5 times rapidly.iddqd (alternate: idkfa).v1.0.0 (dev) and new options appear in the menu..md files on disk and rebuilds the SQLite index from scratch. Fixes missing notes, broken image paths, and duplicate entries.Rebuild Index is a structural fix. Use it when notes are missing from the list, images are broken, or the database is out of sync with files on disk. It reads existing Markdown files and rebuilds the SQLite index — fast (seconds), non-destructive, no AI involved.
Reprocess All Notes re-runs AI on every note — tags, categories, relationship mapping. Use it when metadata is stale, you switched Gemini Nano models, or you imported notes without metadata. This takes significant time on a large library and consumes Gemini Nano's rate limit, so avoid running it casually.
