The Upgrade

Your AI history deserves
better than a chat sidebar.

Every brilliant prompt you've ever typed is disappearing into the void. Mento changes that permanently.

The Default Experience
Trapped Chats Conversations disappear the moment you close a tab or start a new session.
Siloed Knowledge Every project starts from scratch — no context, no memory, no connection.
Flat Chaos No tags, no folders, no way to find that one prompt from last Tuesday.
Manual Grind Constant copy-pasting between AI tools, documents, and Notion pages.
The Mento Advantage
Unified Brain One-click archiving — every question saved, tagged, and searchable forever.
Global Context Connect dots across projects — keyword & tag search finds related ideas instantly.
Deep Organization Auto-tagged by topic — #coding, #writing, #finance — plus custom folders.
Bulk Power Export everything at once — clean CSV or printable PDF, ready to share.

FAQ

Questions answered.

Does Mento send my questions to a server?+
No. Free tier data stays 100% on your device using Chrome's local storage. Pro Cloud Sync uses end-to-end encrypted storage — your prompts are never readable by us.
Which AI platforms does Mento support?+
Free plan covers ChatGPT and Gemini. Pro unlocks Claude, Perplexity, and Microsoft Copilot — all 5 major platforms in one unified vault.
Can I restore my questions on a new device?+
Yes — Mento Pro automatically backs up your questions to an encrypted cloud vault. If you switch browsers or get a new device, simply install Mento, go to Settings, enter your license key and click "Restore from Cloud." All your questions are restored instantly. Everything is encrypted with AES-256 so only you can read your data.
Is Mento Pro a subscription or a one-time purchase?+
Mento Pro is a one-time license key purchase — no monthly fees, no recurring charges, ever. You pay once and get lifetime Pro access. Your license key works on any browser and can be used to restore your questions on a new device at any time.
What happens when I hit the free limit?+
When you reach 20 saved prompts on the free plan, Mento shows a warning. New questions won't be saved until you upgrade or clear older ones. Your existing data is always preserved.
Is the Lifetime deal really lifetime?+
Yes. One payment of $40 gives you permanent access to all Pro features and every future update at no additional cost. We stand behind this commitment.

Your AI conversations
deserve to be remembered.
