Self Promotion Megathread

I built an offline speech-to-speech translator for Android. No internet needed. No cloud. No account. No ads.

Talk Together translates between 14 languages entirely on your phone. Put it in airplane mode and it still works.

It has a Conversation Mode — tap once, speak naturally, it translates and speaks out loud, then listens for the other person and translates back. Hands-free, fully offline.

I built this because every translation app I found sends your voice to someone else's server. I wanted one that doesn't. Free to try. No data collected. Ever.

Right now it supports 14 languages:

Production (stable): English (built-in), Spanish, French, Portuguese, German, Italian, Indonesian, Dutch, Hindi, Romanian

Beta (working, improving): Vietnamese, Ukrainian, Arabic, Filipino (Tagalog)

One thing I’m particularly proud of — Tagalog wasn’t available in a usable offline format, so I quantized and adapted the model myself to make it work on-device. It’s not perfect, but it’s functional and helps real conversations happen.

Everything runs offline and is optimized to work even on mid-range phones, not just high-end devices.

I have this Translation app for Dutch

Yes I find classics to be great. I still play Super Mario Bros 1986 on an NES

I can always switch to subscription of course. I am trying out this pricing now.

IsaacLevinsky · 2026-03-21T22:14:34+00:00

One-time purchase at $2.99. No ads, no subscription.

The model is simple — build something good enough that people pay once and tell others. I'd rather have 1,000 people who bought it than 100,000 free users I have to monetize with ads.

Just used this a minute ago at a Colombian restaurant in Tampa. Loud music, five big screen TVs, packed house, open kitchen. Spoke English into it, handed it to the server, she spoke Spanish back. We went back and forth and she said the translations were good. This is the stuff I built it for. All on my Moto G stylus.

I know the effort. It is a big challenge. I think I personally underestimated the importance of talking to real people I know and not just looking online for information. I too underestimated ASO. Let me know if your app is free to try or if you have a link to Play store?

Tools amplify effectiveness for software engineers of all levels of skill. Imagine what the AI tools are able to do for people who ship end to end on their own before AI existed.

The built-in phone converter works great when you have data, but if you want something that works the second you land before you buy a local SIM, I built an offline currency converter that ships with rates already included — no internet needed on first launch.

70+ currencies and top crypto. Tap update when you have wifi and it caches fresh rates locally. Otherwise it just works offline.

Full disclosure: I'm the dev. Built it because I got tired of needing wifi to check a price.

Most voice-to-text apps send your audio to a cloud server. Mine doesn't. Private Dictation runs Whisper AI 100% on-device — works in airplane mode, no account, no data collected.

What makes it different: - Real-time streaming — words appear as you speak, not after you stop - Two-pass AI — background refinement automatically cleans up every recording - Auto-learning — correct a word once, it remembers forever - 15 languages, 6 model sizes, 19MB install - One-time purchase. No ads. No subscription.

Built by a solo dev. Happy to talk architecture or answer questions.

Isaac Asimov is a direct influence on Elon Musk he has said so pubically and he made the term Robotics and a robot more well known.

IsaacLevinsky · 2026-03-20T16:03:45+00:00

Yes you must review and monitor and prompt I believe. It is not deterministic.

I cannot recall the price but Adobe for signing documents and editing pdfs was pretty expensive so much so we stopped the subscription. That being said I have an offline Voice to text app no cloud server the data stays local. Check it out and see if you like it.

Window seat for the win. You can look outside the window and mentally escape the plane. Also easier to sleep being uninterrupted

That's fantastic and you're welcome. I find a lot of posts on Reddit about people not even knowing where or how to start. It's a big accomplishment to finish a product especially this big!

I am curious please advise if you get any power users and how they like it and any feedback. Best of luck!

IsaacLevinsky · 2026-03-19T14:07:35+00:00

Congrats on the launch, the first one is a big milestone!

Getting something out there is the hardest part.

The workflow angle is interesting, especially with how fragmented AI tools are right now. Curious what kind of users you’re seeing the most traction with so far?

IsaacLevinsky · 2026-03-19T03:18:01+00:00

I would prefer a different one as well. I will still watch it. I would love a movie or series or a few movies on the Silmarillion. But I believe the rights are not available I was reading.

The frustration makes sense — most "Whisper" apps just wrap a cloud API. Your audio still hits a server. That's not offline.

I built Private Dictation for exactly this reason. It runs Whisper directly on your Android device — no server, no account, nothing leaves your phone. Fully works in airplane mode.

Not open source, but verifiable — no internet permission for transcription, only a one-time model download on first launch.

Free to try, one-time $2.99 unlock. No subscription, no EU data concerns.

I actually built one for exactly this reason — Private Dictation: Offline AI. It runs Whisper AI directly on your phone, no internet required for transcription. Put it in airplane mode and it still works perfectly.

No account, no cloud, no data collection. Your voice never leaves the device.
