Invisible memory drift
AI tools quietly accumulate outdated facts, fuzzy preferences, and duplicated context that starts to hurt response quality.

Why MemSync
AI assistants get more useful when memory stays intentional.
MemSync is a free, open-source web app for people who already rely on AI daily. Nothing to install, no software to download. Paste your memory, the audit runs in your browser, and you get a cleanup plan you can act on right away.
Privacy uncertainty
You can't easily see which details feel too personal, too stale, or no longer useful across different assistants.
Manual cleanup is messy
Each platform handles memory differently, so reviewing and rewriting it becomes repetitive and easy to avoid.
How it works
- 1. Paste your AI memory into the web app. Copy it from ChatGPT, Claude, or Gemini settings. No upload, no account needed.
- 2. Get a cleanup plan. MemSync labels what to keep, rewrite, delete, or double-check.
- 3. Apply a cleaner profile. Walk away with a concise memory profile and a per-platform checklist you can act on.
Built on trust
- Privacy-first: your memory never leaves your browser.
- Free for everyone. No strings attached.
- Open source: you can read every line of code.
- Plain-language recommendations instead of generic AI advice.
