MeMex

Verdict: MeMex appears to be a local-first macOS utility that records and indexes recent screen activity into a searchable visual timeline — useful for Mac users who want an on-device way to recall what was on their screen.

What it is

MeMex, as the website describes it, converts recent screen fragments into an organized, sliding timeline you can search or query. The site says captured timeline data is stored on the Mac by default and that you can optionally connect an AI model/provider to generate day recaps.

Who should consider it

• Individual Mac users who want a visual, searchable history of their recent screen activity.
• People who prefer local storage over cloud-first screenshot services and want a timeline view rather than a flat screenshot folder.
• Users willing to enable optional AI integrations for summaries and higher-level queries.

Why it may be useful

• Searchable recall: If you frequently need to find text or UI you saw earlier, a timeline view can speed lookups compared with manual screenshots.
• Contextual review: The sliding timeline UI (as shown on the site) aims to surface a continuous sequence of what you saw, which may help reconstruct tasks or conversations.
• Optional AI recaps: The website describes connecting a model to produce day recaps, which may save time if you want high-level summaries.

Confirmed strengths and trust signals

• Local-first positioning: The website states timeline data is stored locally on the Mac by default.
• Privacy documentation: A privacy policy is published (effective June 26, 2026, per the site) and the developer lists an email for support and privacy requests.

What is unclear or missing (verify these before relying on MeMex)

• Pricing and licensing: the website does not clearly state whether MeMex is free, a one-time purchase, or subscription-based; check the Mac App Store or official site for current terms.
• System requirements: supported macOS versions and hardware requirements are not listed in the reviewed material.
• Capture controls: the site does not clearly state capture frequency, filtering options, or how to pause/exclude apps and sensitive content.
• Encryption and backups: the website does not clearly state whether captured data is encrypted at rest or how backups and any optional sync behave.
• AI processing details: the site does not clearly say which AI providers are supported or whether AI processing occurs locally or is sent to external services.
• Retention and deletion: default retention periods and deletion controls are not described.

Limitations and risks

• macOS only: the site positions MeMex "for Mac" and does not show other platform support.
• Privacy exposure if not configured: because MeMex records screen content, verify capture controls and any off-device transmissions before enabling integrations.
• Incomplete public documentation: several operational and security details are not clearly stated on the site material reviewed here.

What to verify before installing

• Current pricing and trial options on the Mac App Store.
• Exact macOS compatibility and system requirements.
• How to pause, filter, and delete captured content.
• Whether captured data is encrypted at rest and what data, if any, is sent to external AI providers.

Bottom line

MeMex appears to fill a specific niche: a locally stored, searchable visual timeline of recent Mac screen activity with optional AI recaps. That approach may be valuable for users who want searchable recall and prefer on-device storage, but you should confirm pricing, system compatibility, capture controls, and the app's encryption and AI-provider behavior before installing or entrusting sensitive content to it.
