Silagora — Re-enchanting Reality, One Breath at a Time
Silagora is a mobile app that lets users leave anonymous, ephemeral, and geolocated messages — called breaths — in real-world places. No profiles, no likes, no followers. Just the magic of discovering words that exist only here, for a fleeting moment. It’s a calm, humane alternative to traditional social networks, designed to reduce anxiety, encourage presence, and forge a poetic connection with our surroundings.
📱 How to Test the App
Optimized for iOS.
🔗 Live App: Expo Link
🔐 A Silagora account is required to fully experience premium features, suspended tickets, and see your own breaths. This minimal authentication applies to hackathon jurors and testers.
⚠️ Transparency & Eligibility
Silagora was structured and prototyped on Bolt in full respect of hackathon rules. As a first-time, non-technical developer, I faced a persistent runtime error on Bolt that I could not resolve despite multiple attempts. After exporting the code and running it locally, the problem disappeared, confirming the app’s stability. Rather than submit an incomplete prototype, I finalized the version locally with help from GPT, Gemini, and VS Code. I am fully transparent about this, and present the working Expo version as the best reflection of my vision.
🌬️ Core Concept & Impact
Silagora enables people to leave breaths — short, anonymous, ephemeral messages visible only within a 15 m radius, disappearing after 24–48 hours.
No algorithms, no profiles, no data trails.
Its mission is to reduce digital overload and encourage quiet, place-based expression.
🧠 Safety & Moderation
- Privacy-first: no profiles, no tracking, no retention
- Automated pre-filtering to block personal data or offensive language
- Text normalization to catch masked offenses (e.g., repeated letters, caps)
- User reporting to flag inappropriate breaths
- Future roadmap: community validation and a dynamic rules engine for evolving slang
🧭 Context & Vision
Modern platforms saturate our attention and reward performance over sincerity. Silagora was designed as a radical alternative — a space for silent voices, authentic presence, and ephemeral expression. Coming from a social and cultural background rather than engineering, I wanted to build a peaceful, human-centered experience.
🧪 Development Journey
Started on Bolt.new with no prior coding experience. When credits ran out, I exported and continued in local development, supported by GPT and Gemini. Step by step, I learned to code, manage deployments, and deliver a stable product, transforming from a passive observer to an active builder.
🧾 Economic & Social Impact
Silagora rejects ads and subscriptions. Revenue comes from optional purchases:
- premium backgrounds
- premium tickets (extended radius)
- suspended tickets (gift access)
Future B2B/B2G partnerships could license anonymized, aggregated data for civic research, participatory mapping, and emotional analysis of urban spaces, under strict privacy guarantees.
📊 Research, Social Impact, and B2G Data Valorization
Beyond the individual experience, Silagora's strength lies in its ability to generate a novel, qualitative understanding of urban dynamics. By aggregating thousands of anonymous "breaths," Silagora becomes a social macroscope, offering invaluable data for research and public policy, while fully respecting privacy.
Our B2G/B2R (Business-to-Government/Research) valorization model will allow institutional partners to access, through licensing, dashboards and extractions of 100% anonymized data for in-depth studies.
Potential Use Cases:
Urbanism and City Planning:
Emotional Mapping of Neighborhoods:
A municipality could visualize the "emotional pulse" of a district. For instance, they could analyze sentiment density (joy, stress, melancholy...) before and after pedestrianizing a street or creating a new public park. It serves as a public policy evaluation tool based on direct, non-intrusive citizen feedback.Identifying "Echo Places":
Automatically detect the squares, parks, or even streets that generate the most poetic and social interactions, in order to better understand what makes a public space "alive" and draw inspiration for future developments.
Sociology and Urban Anthropology:
Analysis of Micro-Mobility and Subtle Exoduses:
Without ever tracking an individual, the analysis of "Echo Trails" (the succession of anonymous breaths in space) can reveal movement patterns and shifts in habits. A drop in activity in a business district combined with a rise in a residential area can be an early qualitative indicator of new remote work dynamics.Anthropology of Digital Anonymity:
For researchers, Silagora is a unique field of study. What stories do people tell when no one is judging them? What themes emerge in transient spaces (train stations, airports) versus leisure spaces (parks, riverbanks)? It is an open window into the collective unconscious of a city.
Opt-in Citizen Science:
- Invite users, on a purely voluntary basis, to focus their breaths on specific themes (e.g., "What is your feeling about the cleanliness of this neighborhood?") to co-create real-time local diagnostics.
Our Commitment:
All data will be systematically aggregated and anonymized, with no possibility of tracing back to an individual. Transparency on the methodologies used will be absolute. The goal is to provide the keys to building more humane cities, based on the silent voices of those who inhabit them.

🎯 Conclusion: From Concept to Delivery
This journey was more than a technical challenge. With no coding background, I jumped in to create a calm, welcoming space in a noisy world. Step by step, I learned, adapted, and brought Silagora to life. Regardless of the outcome, the project proves that a clear vision, perseverance, and the right tools can turn an idea into a working product — a success I’ll carry far beyond this hackathon.
