This reference lists everything AI Text to Speech 3.2.0 stores: WordPress options, post meta keys, files on disk, and the AJAX and admin-post actions it registers. Use it for migrations, custom queries, debugging or cleaning up after removing the plugin. The plugin doesn’t create custom database tables and has no uninstall routine, so this data stays until you remove it.

Options

Option	Contents
ai_tts_settings	Array of all settings (voice model, player label, storage location, content, automation, player and permission options, Dropbox token expiry, error log).
ai_tts_api_key	OpenAI API secret key.
ai_tts_custom_pronunciations	Array of word / pronunciation pairs (PRO).
ai_tts_api_request_log	Last 50 API request log entries, newest first.
ai_tts_admin_generated_files	Last 50 Generator page files: id, URL, file name, storage, date, model, voice, style.
ai_tts_dropbox_access_token, ai_tts_dropbox_refresh_token	Dropbox OAuth tokens (PRO).
ai_tts_do_activation_redirect	Temporary flag for the redirect after activation.

A transient named ai_tts_dropbox_oauth_state_{user_id} is set for 10 minutes while connecting Dropbox.

Post meta

Meta key	Contents
ai_tts_file_url	URL of the post’s audio file. Its presence is what shows the player.
ai_tts_location	local, dropbox, wp_media or external.
ai_tts_generated_at	Generation date and time (site time, MySQL format).
ai_tts_file_name	File name, stored for non-local storage.
ai_tts_attachment_id	Media Library attachment ID when a file was chosen from the Media Library.
ai_tts_dropbox_file_path	Path of the file in Dropbox (PRO).
ai_tts_stats	JSON: date, view_count, play_count, play_time (PRO).
ai_tts_stats_daily	JSON keyed by Y-m-d for the last 7 days, each with view, play and play time counts (PRO).

Deleting a post’s audio removes the file meta but keeps ai_tts_stats and ai_tts_stats_daily.

Files

Local audio is saved to WP_CONTENT_DIR . '/uploads/ai-text-to-speech/' (the constant AI_TTS_UPLOAD_DIR). This path is fixed and doesn’t follow a custom uploads location set with UPLOADS or the upload_dir filter. File names are:

• Posts: post-{ID}-{2 random characters}-{first 10 words of the title slug}.mp3
• Generator page: admin-{10 random characters}.mp3

AJAX and admin-post actions

Action	Access	Purpose
generate_tts	Logged in, nonce ai_tts_nonce	Generate audio for a post or Generator text.
delete_tts	Logged in, nonce ai_tts_nonce	Delete a post’s audio.
set_tts_file	Logged in, nonce ai_tts_nonce	Attach a Media Library or external audio URL.
increment_play_count	Public, nonce ai-tts-nonce	Record a play (PRO).
refresh_stats	Logged in, nonce ai-tts-nonce	Delete a post’s statistics (PRO).
start_dropbox_oauth_process, aitts_dropbox_callback, disconnect_dropbox	Administrators (admin-post.php)	Dropbox connection flow (PRO).

Remove all plugin data

Back up your database first. With WP-CLI:

wp option delete ai_tts_settings ai_tts_api_key ai_tts_custom_pronunciations ai_tts_api_request_log ai_tts_admin_generated_files ai_tts_dropbox_access_token ai_tts_dropbox_refresh_token
wp db query "DELETE FROM $(wp db prefix)postmeta WHERE meta_key LIKE 'ai_tts_%'"
rm -rf wp-content/uploads/ai-text-to-speech

Delete audio stored in Dropbox from your Dropbox app folder separately.
