Flashback Labs: Building Private AI Interactions on Oasis
Exploring how personalized AI translates into onchain activity.

Most onchain activity is financial. Flashback Labs is building something entirely different - a platform where people talk to an AI about their lives, preserving memories before they fade or loved ones pass away. Every conversation generates encrypted files and onchain transactions. The result is 1,000+ users driving 700+ daily transactions on Oasis, all with essentially zero marketing spend.
What flashback does
Flashback is a conversational AI app. Users either pick a prompt, "I visited my grandparents", for example, or run stream of consciousness with a voice assistant. The chatbot asks follow-up questions and extracts structured data around the people, places, emotions, and timelines.
From that conversation, the AI generates a "flashback" - a short animated video combining photos, text, and voice narration that brings the memory to life. It also builds a graph of people mentioned across sessions (siblings, grandparents, friends), so the more someone uses it, the richer and more personal the experience becomes.
The main point is preservation. Details fade, people pass away, conditions like Alzheimer's accelerate the loss. Flashback captures what's in someone's head while it's still there.
How flashback leverages oasis
The Flashback app handles some of the most sensitive data imaginable: personal memories, family relationships, health conditions, grief, etc. Whether or not the app works, depends entirely on users trusting that this data is private and verifiable.
In this sense, Oasis provides the encryption layer.
Since the storage networks Flashback integrates with (0G, BNB Greenfield) don't offer their own encryption mechanisms, Oasis’ confidential network fills this critical gap. Every file is encrypted within a confidential smart contract before being committed to storage. Users can verify onchain that their data is encrypted and accounted for.
Traction
The team has spent very little on marketing so far and there are no active token incentives. Yet the numbers are real:
- 1,000+ users
- ~200 encrypted files created per day
- ~700 onchain transactions generated per day
- 29 new users on a single recent day
The team is positioning Flashback as a privacy-first product for a mainstream audience. If adoption continues on this trajectory, transaction volumes will scale naturally with user growth.
What's next
Flashback's near-term applications sit somewhat outside crypto. Currently, the team is orienting the product toward Alzheimer's care. There's also a partnership in development with notable bereavement nonprofits in the US who will offer the product to people processing the loss of a family member. Both efforts are already underway.
An agentic framework is also in development that will let the flashback AI proactively reach out to users across channels to collect memories, rather than waiting for them. The team is also exploring hardware integrations, including robotic companion devices running the AI for hospice and elder care settings.
Every one of these interactions feeds back into the same pipeline: AI analysis, file generation, encryption, and then onchain storage. As Flashback grows its user base into healthcare and grief support, Oasis grows with it.
