I built an AI roleplay partner for rehearsing hard conversations. Where does it fall short?
I'm Anton, founder of Talkasu (https://talkasu.com).
It's for the conversations people avoid or blow: asking for a raise, saying no to a boss, setting boundaries with family, getting a kid to listen without yelling, repairing after a fight. There are 13 short trainings. You practise against an AI counterpart that stalls, deflects or gets defensive, and you get clearer wording to try next.
It works on the web and on Android, and it's free to start with free daily credits (there's an optional subscription).
Sending a certificate batch? Free roster-check help or one software comparison
If you run workshops or training courses, I can help you check a PDF batch or compare two software options for free.
Sending certificates?
RosterSplit splits a text PDF by recipient, names the files from your CSV roster, and flags missing recipients, possible duplicates and unclear matches. Your files stay in your browser.
FxMap: an open-source .NET library that fills DTO fields from other services
Sharing a free, open-source library I maintain for .NET microservices.
The problem: an order DTO has a UserId, and you end up calling the user service, batching the ids and copying Name and Email back by hand, again and again.
How FxMap does it: the service that owns the data says how an entity is exposed. In the DTO you write a profile: this key fills these fields, optionally with a small expression such as Country.Name. Then one call to MapDataAsync on a list sends one request per key, not one per object. It works over gRPC, NATS, RabbitMQ, Kafka, Azure Service Bus and AWS SQS, reads from EF Core or MongoDB, and has a HotChocolate (GraphQL) integration.
Honest limits: .NET only (8, 9 and 10), gRPC calls have a fixed 3 second timeout in the current version, and the test suite is 826 tests with about 62% line coverage. Load test numbers and a benchmark are on the Testing page of the docs.
I built APILens to show where a slow Node.js request spends its time
Hey Product Hunt,
I'm building APILens, a Node.js API observability tool.
Jeenly - make your personal mobile app in minutes
I m building Jeenly, an iPhone app that creates small personal tools from the prompt.
For example, you might describe a tracker designed around your routine, a calculator for a decision you make repeatedly, recipe generator tailored for your preferences, or a simple planner that works exactly the way you want. Jeenly creates the tool, lets you use it immediately, and lets you improve it by describing changes.
To start with, tools have capabilities of using ai and calling public apis, more capabilities (like notifications, image generations) yet to come!
Record screen and edit in same app — or let your AI do it: product demos, tutorials and lessons
Hey, I am a solo maker of Screen Records Mac app.
If you need to record your screen often you know the problems: heavy recorders, monthly subscriptions, need to edit everything separately for each social, then generate captions in another app.
Many recorders are just inconvenient. I tried 9 and bought 1, because I thought making own one is not worth it.
But I had to do it anyway, since app I bought just didn't work right.
So now I'm building a lightweight native MacOS screen recorder with built in editor. One-time purchase. Nothing extra for captions and MCP for your favorite AI subscription to open projects, edit and export them in front of you. Plus a lot more nice convenient features you may expect from screen recorder.
Every change can be undone, app never spoils original footage. Every track can be edited separately (mic, video, voiceover, system sound, camera).
Zooms and background changes are in too. You can even paste media into recording, change places of video parts.
Give it a try: free version available and lifetime deal now is only $29.
Please share, what would make demo recording effortless for you?

How should a cost-planning app communicate uncertainty before a manufacturing quote?
Hi everyone, I m Bruce, the maker of RecipeCat. I m building a tool to help people work through the steps between a recipe and a packaged food-product plan.
I d like feedback on a specific product-design question: how should an app present an early cost estimate when some inputs are still assumptions?
In our recorded example, a proposed 227 g sauce bottle has an estimated unit cost of $5.42. That provides a starting point for exploring pricing, but supplier prices, packaging, actual yield and production quantity can change the result. Manufacturing partners still need to confirm feasibility and final pricing.
My view is that a single total is easy to understand, but it can hide uncertainty. I d favor an itemized estimate with editable assumptions and a clear distinction between estimated costs and confirmed quotes. Showing a range is another option, though that range also needs a defensible basis.
Inquir Compute is live today: apps, databases and background jobs
I m launching the new version of Inquir Compute on Product Hunt today.
It started as a serverless runtime. This release adds container apps and databases, so a web app, its database and background work can live in one workspace.
Deploy from GitHub, a Dockerfile or a container image.
Connect Postgres or Redis over a private network.
Run functions and scheduled workflows alongside your app.
Check releases and logs from the console or CLI.
I d like feedback on the first deployment. What would you need to see before trusting a new platform with a small project? A working example, clearer pricing, migration docs, or something else?
Is "Local-First" software making a comeback? Why we stopped linking bank accounts for budgeting.
For years, the gold standard in personal finance apps has been linking your bank account, storing data in the cloud, and paying $10/month for a subscription.
But lately, there seems to be a major shift. Many users are experiencing payday friction with traditional apps:
Privacy Concerns: Sharing bank credentials with third-party aggregators feels increasingly risky.
Over-Engineering: Having a simple payday budget turned into complex setups with forced account creation and endless ads.
Data Ownership: If a cloud service shuts down or changes its pricing, your entire history is locked in.
We decided to test a different approach: building a 100% offline, privacy-first mobile budget tracker (Jetpack Compose, native CSV/JSON export, zero cloud tracking).
Free printable worksheet makers with answer keys: what would you add?
Hi everyone. I run PrintSheetLab, a free site for teachers and parents.
It has 1,300+ printable worksheets with answer keys, plus makers for math worksheets, bingo cards, word searches, flash cards, graph paper and calendars. No sign-up and no ads.
https://printsheetlab.com/
Most worksheet sites give you a fixed PDF. Here you pick the number range, print several versions of the same sheet, and the answer key is on page 2.
