How HosTalky Uses PowerSync as the Sync Layer for Its AI-Powered Healthcare Platform
I first met the HosTalky team in March of 2025 when they were looking for a Realm replacement. We’ve had a long working relationship and they’ve helped us make various product improvements during that time. In this post I chat to them about their healthcare platform.

We’ve added an India region to PowerSync Cloud (ap-south-1) If you’re building for users in India, you can now host PowerSync closer to them. We already work with great customers in India, and there’s good time zone overlap with our engineering teams based in Europe and Asia.

Reflecting on the past year we observe that Sync Streams are bigger and better, and don't remove any existing functionality that users love. Therefore we're comfortable to announce that in T+15 months, legacy Sync Rules will be phased out entirely. releases.powersync.com/announcemen...

Our Plan for Phasing Out Sync Rules
We're phasing out Sync Rules in favor of Sync Streams over the next 15 months. From 15 March 2027, new PowerSync Cloud instances can only use Sync Streams. From 15 December 2027, you can no longer deploy Sync Rules and support for them ends.

Compaction logs are now visible in the PowerSync Dashboard! PowerSync keeps a history of relevant source database changes so reconnecting clients can efficiently catch up. This operation history can become large, so compaction is required. It runs automatically on PowerSync Cloud, now with logs

If your AI app needs durable runs, resumable streams, background jobs, and shared history to be reliable, you're already partway to multiplayer. The next step is making that state collaborative so that your agents can align with not just a single user, but an entire team.

Most AI apps still package the experience as a private session: one user, one thread, one hidden context window. But real work is collaborative. If AI is going to participate in real workflows, its output needs to become shared state. Learn the why and the how in this post by @devagrawal09

Most AI chat apps are built like demos. 📉 If you refresh the page or lose connection mid-generation, the response is gone. Why? Because we're treating LLM outputs as fragile streams instead of synced state. Learn how to fix your broken AI apps in this latest blog post by @devagrawal09.

"How much of this can be local" should be the default question every dev asks. Most have gotten too comfortable with defaulting to remote hosting even the tiniest services. Glad to see a growing pushback for local-first. A nice mini-doc from @cultrepo.bsky.social www.youtube.com/watch?v=10d8...

If you're building this weekend for the PowerSync AI Hackathon, resist the urge to keep expanding the project. Get the core flow working. Make the value obvious. Make sure someone can understand the product quickly.

PowerSync @powersync.com · 19/03/2026
You can still start a PowerSync AI Hackathon project this week and submit something strong by Sunday. Keep the scope tight. Pick one user, one workflow, and one place where sync, offline support, or durable local state makes the product noticeably better.

PowerSync @powersync.com · 18/03/2026
With the deadline now on Sunday, this is a good time to simplify. The strongest submissions usually have: - a clear use case - a focused demo - an obvious reason PowerSync matters A smaller project that is easy to understand will go further than a bigger one that tries to do everything.

PowerSync @powersync.com · 18/03/2026
Update: we're extending the PowerSync AI Hackathon submission deadline to Sunday, March 22 at 11:59 PM CT. More time to finish strong, polish demos, and get submissions into good shape. If you're already building, keep going. If you haven't submitted yet, you've got the weekend.

A good PowerSync AI Hackathon project usually starts with a simple question: What AI product becomes much more useful when it keeps working across devices, handles weak connectivity well, or keeps state locally? That’s where the most interesting ideas tend to come from.

Looking for a PowerSync AI Hackathon idea? Ask your coding agent: "Give me 5 ideas for the PowerSync AI Hackathon. Focus on AI apps where offline support, cross-device sync, or durable local state clearly improves the product." Choose one and start building. Deadline: Friday, March 20.
