[Campaign Category] Category Questions

Describe what makes your idea innovative compared to what has been previously funded (whether by you or others).

Our idea was not inspired by any previously funded project. It originated from using Read.ai, which I found useful since people rarely revisit meeting recordings and summaries are more practical.

However, for important meetings, a simple summary is not enough. Our innovation combines AI-generated summaries with participant approval and blockchain anchoring, ensuring both accuracy and immutability - something not previously funded in the ecosystem.

Describe what your prototype or MVP will demonstrate, and where it can be accessed.

Our MVP will demonstrate how meeting recordings can be automatically summarized by AI, reviewed and approved by participants, and then anchored on the Cardano blockchain to ensure immutability and trust. It will include a working bot that joins Zoom meetings, generates summaries, and stores records on IPFS. The MVP will be accessible via a public GitHub repository and a demo landing page that guides how to interact with the bot.

Describe realistic measures of success, ideally with on-chain metrics.

For short term (first month):

1. 100+ meeting sessions that will be create transaction on Cardano and stored on IPFS.
2. 50+ unique wallets interacting with the bot.
3. 10,000+ campaign impressions from launch marketing.

For long term (first year):

1. 1500+ meetings sessions created.
2. 200+ unique wallets interacting with the bot.
3. 20+ regular users who create at least 2 sessions/week.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

Problem We're Solving

We see a big problem with online meetings, there’s often no trustworthy, automatic way to keep records and notes. Traditional minutes can be changed, or even intentionally twisted, which is a real concern for DAOs and communities built on trust. That’s why we’re building a Zoom bot that records in the cloud, turns speech into text with AWS, creates clear summaries with Bedrock, and securely stores everything on the blockchain. With multi-sig, we ensure everyone involved signs off before it’s shared.

Why a Zoom Bot?

Zoom is a reasonable platform to integrate our bot which can join meetings on its own, start recording without anyone lifting a finger, and pull clean audio straight from Zoom’s cloud. It guarantees every meeting is recorded, even if nobody remembers to hit “Record” and it connects directly to AWS and the blockchain so the notes are secure, tamper-proof, and built on trust.

Solution Details

Solution Flow: Cloud Recording →AI summary → Multi-Sig → Blockchain Publish

1. Recording and Retrieval
   1. The bot automatically joins scheduled Zoom meetings or enters on-demand via an invitation link.
   2. Once in the meeting, it triggers Zoom Cloud Recording without requiring manual action from participants.
   3. At the end of the session, Zoom triggers a webhook that alerts our backend.
   4. The backend downloads the audio/video from Zoom Cloud and stores them in AWS S3 for secure, scalable storage.
2. Transcription and Summarization
   1. AWS Transcribe is used to convert speech to text with speaker diarization, ensuring transcripts clearly identify who said what.
   2. Transcript is summarized using an LLM (Claude, Llama) to produce meeting minutes in a PDF file which includes: agenda, meeting information, key decisions, action items,…
   3. The output is structured in a standardized, readable format for later blockchain storage.
3. Multi-Signature Approval
   1. Before publication, the bot hashes the audio, transcript, and summary into a single cryptographic fingerprint.
   2. This hash is sent to all authorized participants via their Cardano-compatible wallets (CIP-30).
   3. Each participant reviews the content and digitally signs the hash.
   4. The is an option for publishing happens only when over 66% of participants approve (if enabled).
4. On-Chain Publishing
   1. The approved files are uploaded to IPFS (InterPlanetary File System) for decentralized storage.
   2. The IPFS CID (Content Identifier) and the hash are embedded in a Cardano NFT CIP-68.
   3. The NFT metadata also contains signer identities and digital signatures for future verification.

This ensures meeting records are always accurate, accessible, and tamper-proof, fostering trust, enhancing collaboration efficiency, and providing long-term value for all participants and stakeholders.

[Your Project and Solution] Impact

Please define the positive impact your project will have on the wider Cardano community

Who Benefits and Why It's Important to Cardano

We’re building this for anyone who needs meeting records they can actually trust from DAOs and Cardano-native projects, to legal teams, governance committees, and remote organizations. These groups often face the same problem: meeting outcomes can be forgotten, misrepresented, or altered after the fact.

For the Cardano ecosystem, this project is more than just recording meetings, it’s turning blockchain into the backbone of real-world governance tools. With verifiable decisions, transparent processes, and proof of consensus, Cardano becomes the platform where what’s agreed in a meeting stays agreed.

Impacts

• Empower DAOs, project teams, and governance groups with immutable meeting records.
• Build trust and strengthen governance through verifiable, multi-signature approved summaries.
• Increase transparency for the Cardano community and external stakeholders.

Value to the Cardano Community

• Reliable, tamper-proof meeting history for governance and voting.
• Publicly verifiable records that demonstrate Cardano’s commitment to transparency and accountability.
• A unique governance tool that other ecosystems lack, showcasing Cardano’s real-world utility beyond finance.

In short, this project transforms Cardano into a trusted record-keeper for human collaboration, proving that blockchain can secure not just transactions, but truth itself.

[Final Pitch] Value for Money

How does the cost of the project represent value for the Cardano ecosystem?

Our project delivers significant value to the Cardano ecosystem at a reasonable cost by solving a real-world need: capturing, summarizing, and verifying online meeting content. The bot automates the process of transcribing and summarizing Zoom meetings (and other platforms in future), then stores the results on IPFS and anchors them on the Cardano blockchain ensuring transparency, accountability, and tamper-proof record-keeping.

The total cost is modest relative to the potential impact, with a clear breakdown of infrastructure, development, QA, documentation, and contingency. With only 78,362 ADA, this project brings blockchain-powered accountability to real-time communication as a scalable utility with many future use cases.

Considering the technical complexity, scope and usefulness, this is a remarkably low cost to build such a comprehensive, production-ready system for the Cardano ecosystem.
