How to sync Context across AI Assistants (ChatGPT, Claude, Perplexity...) in your browser

Anmol Baranwal on June 24, 2025

Most people today use more than one AI assistant such as ChatGPT, Claude, Perplexity. But none of them share context. You end up repeating the sam...

I'm trying to understand the privacy parts. Is this locally hosted on the device or sent off to a server?
In the same line of questioning, is it cross-device accessible? Say from home to work and back.

It's not locally hosted, data is saved in Mem0 cloud server (as I showed in the blog). Yes, it works across multiple devices since everything is stored in the cloud. You can check more in the FAQs. hope this helps!

Context consistency is indeed a pain point!
I solved this with ChatGOT—multiple large models can switch freely within a single conversation (like GPT, DeepSeek, Gemini, etc.), and the AI remembers the previous conversation context, making the transition seamless and much more efficient.

Yes you're right,it's a perfect combo once you know how to navigate 👍🏾

Thanks for checking this out John. I'm using the extension too :)

Being able to sync context across ChatGPT, Claude, and others is honestly such a win. Curious if you noticed any context mix-ups or issues when switching between really different assistants?

So far I haven't noticed any problems (the extension is still very new).

If there could be a way to see which aggregator (ChatGPT, Perplexity, Gemini....) a memory was saved from, that would be useful imo.

how much are you paying for all this if you dont mind me asking?

It's free and open source with no usage limits (and no ads). Even though I love the extension, I doubt I would have used it if it was paid.

This is extremely impressive and honestly solves a real headache. Appreciate how deep you went into both the pain points and the technical side

pretty cool seeing someone actually fixing my context headaches, tbh makes me wonder though - you think folks will stick with something like this for the long haul or just bounce around to new tools all the time?

I think people will stick with this especially because the extension is free & open source. It’s built for the community and already supports major AI assistants (with more coming soon).. so I’m sure this will be useful.

For me the layer that ends up sticking isn't the one with the longest feature list — it's the one with the thinnest API surface. OpenMemory is doing real work as the persistent-context layer; what I've kept reaching for as a complement is a read-only side-panel bridge: select text or annotate a screenshot on any page, dispatch to whichever model fits the task (Claude for nuance, ChatGPT as the default, Gemini for long-context, DeepSeek for cheap bulk). No persistent store, no cross-tab memory, no sync daemon — just a gesture that lets me ask without leaving the page.

The reason I think this kind of split lasts: the two extensions solve different jobs. OpenMemory owns "remember this for next time"; the side-panel bridge owns "get me an answer right now about what I'm already looking at." When you force both jobs into one extension, you end up with permission scope and surface area that nobody wants on a sensitive doc. When you let them stay separate, each one stays small enough to audit and trust.

The stickiness signal I've seen in my own usage: the model choice happens per ask, not per day. On a research day it's Claude 70% of the time. On a code-review day it's Gemini because the free tier covers the long context. The product that lasts is the one that gets out of the way of that per-ask routing.

The idea is good, but not for work. Will not share my memories with memories.

Does it work in PWAs as well?
