Description
What began as “Thought Log,” a simple archive for ChatGPT, has evolved into Idevo — a beautifully crafted, privacy-first knowledge companion for the AI age.
Idevo helps you preserve your most valuable conversations and ideas by importing your ChatGPT history and turning it into a permanent, organized record.
Save important answers, revisit insights from months ago, and trace how your thoughts evolve over time.
Idevo now supports a freemium model.
The Basic plan (free) includes all core features—PDF export, Favorites, Timeline view, and more.
The only limitation is an import window of up to 3 months of chat history.
There are no ads, no tracking, and Idevo works entirely offline to protect your privacy.
