Footnote turns spoken content into live context — generating instant knowledge cards for every key person, place, and concept as it’s mentioned.

The Idea

SUMMARY: Footnote is a real-time context companion that turns spoken content — podcasts, talks, and conversations — into interactive knowledge cards, helping listeners instantly understand people, places, terms, and references as they appear.

Problem.Audio and spoken content move fast. Podcasts, interviews, and technical discussions often reference people, companies, events, and concepts without explanation. Listeners must pause, search manually, or ignore unfamiliar references — breaking flow and reducing comprehension.

Traditional show notes are static and incomplete. Search engines are separate from the listening experience. Context is fragmented.

Insight. When context appears at the moment of mention, comprehension rises and engagement deepens. Listeners don’t want to leave the experience — they want the experience to become richer in place.

A lightweight, real-time context layer can transform passive listening into active understanding.

Solution. Footnote is a context engine that detects referenced entities in spoken content and generates live, structured context cards. These cards provide instant background — who, what, where, and why it matters — without interrupting playback.

Instead of stopping to look things up, listeners stay immersed while the knowledge layer unfolds alongside the audio.

Footnote functions as a “second mind” for spoken content — ambient, supportive, and on-demand.

Proof of Work

A live prototype is currently available demonstrating:

• Real-time entity detection from spoken content
• Automatic generation of structured context cards
• Card-based UI for quick scanning
• Multi-entity extraction from continuous dialogue
• Working Base44 implementation and demo flow
• The prototype validates the core interaction model: listen → detect → enrich → display.

Roadmap

Phase 1 — Core Context Engine

• Improve entity detection accuracy
• Expand card types (people, companies, places, terms)
• Faster extraction and rendering pipeline

Phase 2 — Experience Layer

• Browser companion mode
• Podcast player integrations
• Timestamp-anchored cards
• Save & revisit context trails

Phase 3 — Intelligence Layer

• Personalized knowledge profiles
• Topic clustering across episodes
• Cross-episode concept linking
• Research and study modes

Phase 4 — Platform API

• Creator embedding tools
• SDK for podcast platforms
• Context-as-a-service API

Use of Funds

Funds support:

• Model tuning and entity extraction accuracy
• Real-time processing infrastructure
• UX refinement and card interaction design
• Integration tooling for podcast and audio platforms
• Performance scaling for live streams and long-form content

Risks, Contraints & Disclaimer

Risks & Constraints

Real-time language processing and entity resolution remain probabilistic and may produce incomplete or incorrect context cards. Accuracy improves with model refinement and feedback loops but cannot be guaranteed in all cases.

Footnote is an informational enrichment tool and should not be relied upon as a sole source of truth. Users should verify critical facts through primary sources.
