Doesn’t work for me, unfortunately. I use Chromium.
Firefox worked. However, I see a few UX issues there. First, I couldn’t sign up until I checked the box, which is all the way down, and IMO it should be located before the Sign Up button. Second, when I finally signed up, nothing happened, so I had to click Sign In to get something happen.
Still not sure why Chromium (or possibly Chrome) won’t work.
It opens in Chrome.
I ticked the box, used “sign-up with google”
and accessed the platform.
generated an API Key as a plus..
maybe others can still try Chrome/Chromium
Following Mike’s note it appears the link may be unable to open when using Chromium and Chrome, so I will flag this for your reviewer that potentially only select browsers will be successful.
I have to take it back, the demo just worked on Chrome on another PC.
The UX issues I mentioned are still there, though.
Hi @Princess - your technical reviewer has noted the following items that will need to be fixed before we can mark this grant ‘Complete’:

Chi Voice is a community-driven language preservation platform enabling speakers of indigenous and global languages to record AI-generated prompts, with all audio archived to decentralized storage.
The platform uses a structured task progression system — Words → Phrases → Sentences — with 1,000 recordings per section, giving contributors clear milestones and measurable progress.
During this grant, the following was delivered:
Sia/S5 Decentralized Storage Integration:
Integrated S5 (the decentralized storage protocol built on Sia) as the archival layer for all recordings. Every recording is asynchronously archived to Sia mainnet, receiving a sia:// content identifier (CID) that can be resolved by any S5-compatible node.
Public REST API:
Launched a freemium public REST API, giving researchers, linguists, and developers programmatic access to the recorded corpus. The API supports filtering by language code, recording type, and pagination. Each response includes the sia:// CID alongside a signed, time-limited HTTPS audio_url for direct audio playback — making the data accessible without requiring S5 infrastructure. API access is governed by key-based authentication with a free usage tier.
Decentralized protocols are not very hard to work with
Building a public API before there is a large corpus of data, forced clarity around data structure and schema decisions that would have been painful to fix later. Designing for external consumers early was the right call.
My support in protecting endangered and under-represented languages with the use of decentralized storage.
Hello @mecsbecs
I’ve made all required fixes
Hi @Princess - your reviewer has noted the PR is not merged yet and even if it was it does not actually remove .s5data/auth.json, it only adds that path to .gitignore which will prevent it from being commited in the future but does not delete the file that is already in the repository. They recommend you look here to learn how to completely remove a file from Git history: https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/removing-sensitive-da…
And then you can revoke and regenerate your s5 credentials used on the production server.
Let me know when this has been completed.
I appreciate this @mecsbecs
I have been able to implement the requested changes,
Thanks again.
Great! Your technical review is a success and this grant can now be marked as complete.
