Memory Sync is a Chrome extension that helps you keep one portable memory layer across AI assistants. It lets you pull memory from one platform, refine it in a single editable Memory.md, and push it into another without reteaching your preferences, background, project context, and working style from scratch.
It currently supports ChatGPT, Claude, Gemini, Grok, Kimi, Mistral, and Copilot. The workflow is intentionally human-in-the-loop, so memory stays visible, reviewable, and under your control instead of becoming a black-box feature locked inside one platform.

Memory Sync's answer:
Memory Sync treats AI memory as a portable asset instead of something locked inside one assistant. Instead of asking users to rebuild their preferences and context from scratch in every tool, it gives them one editable Memory.md they can review, refine, and sync across assistants.
The other important difference is the workflow itself: it is intentionally human-in-the-loop. Users can see what is being preserved, edit it directly, and stay in control rather than relying on a black-box memory feature they cannot inspect.
Memory Sync's answer:
A person should choose Memory Sync if they use more than one AI assistant and want continuity without vendor lock-in. It is especially useful for people who already have valuable context stored in one platform and do not want to lose it when they switch tools or experiment with new ones.
Compared with products that keep memory hidden inside a single system, Memory Sync makes the memory layer visible and editable. That means users can carry forward their preferences, project context, and working style with more transparency and control.
Memory Sync's answer:
Memory Sync is built for people who actively use AI tools for real work and want their context to travel with them.
That includes founders, operators, developers, researchers, writers, and power users who move between assistants like ChatGPT, Claude, Gemini, and others. In general, the audience values speed, continuity, and control, and does not want to repeat the same preferences and background information in every new AI workspace.
Memory Sync's answer:
Memory Sync came from a simple frustration: people are starting to build real working relationships with AI assistants, but the memory they create is usually trapped inside each platform.
As more users switch between tools for different strengths, they lose preferences, project context, and accumulated background every time they move. Memory Sync was created to make that memory portable, editable, and user-controlled so people can keep continuity across assistants instead of starting over each time.
I've started with Simplenote years ago, at the time I was happy but it became clear pretty quickly that it was too basic. But to be fair, it's basic and free. Keep in mind it's unencrypted.
Was looking for an alternative for OneNote, so I found it here. I like how simple the interface is and the UI is very simple. It's good for what it is, but there is no sorting/topic system which makes it difficult to find specific notes for specific topics. Other than that, it's a good note system.
Based on our record, Simplenote seems to be more popular. It has been mentiond 83 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
I've been looking to migrate away from https://simplenote.com to something else and I've been dragging my feet. However, what's happened in the past 2 weeks with the CEO was the push I needed to resume looking for another solution. I've landed on Obsidian.md. I actually prefer Simplenote over Obisidian, because Simplenote feels smoother and the online web app is great, but I've decided that having more control... - Source: Hacker News / almost 2 years ago
I use https://simplenote.com - Syncs across multiple platforms. - Plaintext based (with MD support). - Search + edit UI similar to https://notational.net and https://brettterpstra.com/projects/nvalt - Simple to publish/share notes - Free (as in beer and speech) --- If I used MacOS or there were web versions, I would love to use the following (they are all better at plaintext than SimpleNote): -... - Source: Hacker News / almost 2 years ago
Bookmarks serve two purposes: - Quick access to commonly used links. For this, I built https://multi-launch.leftium.com - Saving a link for future reference. Often I want to also save plain text notes for future reference, so find myself using https://simplenote.com I have also used https://www.bkmks.com to save links. I'm working on an app that will help save and organize everything: bookmarks, notes, and tasks. - Source: Hacker News / about 2 years ago
It doesn't meet the poster's needs, but Simplenote is still a thing for people who want text-only notes, Markdown, and easy access to plain text files. It got acquired by Automattic a few years back. https://simplenote.com/. - Source: Hacker News / about 2 years ago
Https://noteplan.co is a very similar app. Unfortunately I couldn't use it because it was limited to iOS devices (a web version is in development). - One thing missing in craftnote is search. That is a must-have feature for me. - I also like being able to publicly share notes with a (short) URL. See https://simplenote.com for an example of how this is done. Nice job with allowing your app to be usable without... - Source: Hacker News / about 2 years ago
