Captures live audio streams from video conference platforms (Zoom, Teams, Google Meet) and converts speech to text in real-time using cloud-based ASR (automatic speech recognition) with speaker identification. The system maintains a rolling buffer of audio chunks, processes them through a speech recognition API, and tags utterances with speaker identities by analyzing audio characteristics and meeting participant metadata. Transcription is streamed to the UI as it completes, enabling live note-taking without post-call processing delays.
Unique: Implements real-time streaming transcription with speaker diarization directly integrated into video conference UIs (browser extension or native plugin) rather than requiring post-call file uploads, reducing latency from minutes to seconds and enabling live note-taking workflows
vs alternatives: Faster real-time transcription than Otter.ai's post-call processing model, but lower accuracy on technical terminology than Fireflies.io's specialized domain models
Processes completed transcripts through a multi-stage NLP pipeline: first, a summarization model (likely fine-tuned T5 or BART) condenses the full transcript into 2-3 paragraph executive summary; second, a named entity recognition (NER) + dependency parsing layer identifies action items, decisions, and owners by detecting imperative verb phrases and linking them to speaker identities; third, a topic segmentation model breaks the meeting into logical sections (agenda items, discussions, decisions). The system uses extractive + abstractive hybrid summarization to preserve exact quotes while generating coherent prose.
Unique: Combines extractive + abstractive summarization with structured action item extraction via NER and dependency parsing, generating both human-readable prose summaries AND machine-readable decision/action JSON in a single pass, rather than treating summarization and extraction as separate tasks
vs alternatives: More structured output (explicit action items + decision log) than Otter.ai's free-form summaries, but less sophisticated than Fireflies.io's custom summary templates and integration with project management tools
Indexes all meeting transcripts using full-text search (likely Elasticsearch or similar) combined with semantic search via embedding vectors (sentence transformers or OpenAI embeddings). When a user searches, the system performs hybrid retrieval: keyword matching for exact phrase queries (e.g., 'budget approved $50k') and semantic similarity for conceptual queries (e.g., 'what did we decide about pricing?'). Results are ranked by relevance and returned with context snippets showing the speaker, timestamp, and surrounding dialogue. Supports filtering by date range, attendees, and meeting type.
Unique: Implements hybrid full-text + semantic search on meeting transcripts with speaker-aware context windows and temporal filtering, enabling both exact phrase retrieval (for compliance) and conceptual search (for decision discovery) in a single query interface
vs alternatives: More flexible search than Otter.ai's basic keyword matching, but less integrated with CRM/project management systems than Fireflies.io's Salesforce and HubSpot connectors
Stores meeting recordings (audio or video) in cloud object storage (likely AWS S3 or similar) with automatic transcoding to multiple bitrates for adaptive streaming. The playback interface synchronizes the transcript timeline with video/audio playback: clicking a transcript line seeks the recording to that timestamp, and the current playback position highlights the corresponding transcript line in real-time. Supports variable playback speed (0.5x to 2x) and speaker filtering (hide/show specific speakers' audio). Recordings are encrypted at rest and access-controlled via user permissions.
Unique: Implements bidirectional transcript-video synchronization (click transcript to seek video, video position highlights transcript) with speaker-level filtering and adaptive bitrate streaming, enabling non-linear review of meetings without requiring manual timestamp lookup
vs alternatives: More integrated transcript-video experience than Otter.ai's separate transcript and recording views, but less sophisticated than Fireflies.io's clip generation and highlight extraction features
Integrates with calendar systems (Google Calendar, Outlook, Zoom, Teams) via OAuth 2.0 to detect scheduled meetings and automatically join video calls. When a meeting starts, Hedy's bot joins the call (as a participant or via platform API), captures audio, and begins transcription without requiring manual user action. The system extracts meeting metadata (title, attendees, duration) from calendar events and associates it with the transcript. Supports recurring meetings and handles timezone conversions for global teams.
Unique: Implements OAuth-based calendar integration with automatic bot joining and meeting metadata enrichment, eliminating manual capture initiation and associating transcripts with calendar context (attendees, agenda, duration) in a single workflow
vs alternatives: More seamless than Otter.ai's manual meeting start requirement, but less flexible than Fireflies.io's support for multiple calendar systems and custom meeting exclusion rules
Aggregates data across all meetings to generate analytics: meeting frequency trends, average meeting duration, attendee participation rates, decision velocity (time from discussion to decision), and topic frequency analysis. The dashboard uses time-series visualization (line charts for trends), heatmaps for attendee participation patterns, and word clouds for common topics. Data is computed via batch jobs (daily or weekly aggregation) rather than real-time, and results are cached for fast dashboard load times. Supports filtering by date range, attendee, and meeting type.
Unique: Provides team-level meeting analytics (participation patterns, decision velocity, topic trends) via batch-computed dashboards with filtering and time-series visualization, enabling managers to identify communication inefficiencies without manual analysis
vs alternatives: More comprehensive analytics than Otter.ai's basic meeting count, but less actionable than Fireflies.io's integration with CRM systems for sales-specific insights
Provides a web-based editor for users to manually correct transcription errors (typos, misheard words, speaker labels) after the meeting. Changes are tracked with version history: each edit creates a new version with timestamp and user attribution, allowing rollback to previous versions. The editor uses a diff-based approach to highlight changes between versions. Corrections can be applied to individual words, phrases, or entire speaker turns. The system supports bulk find-and-replace for common errors (e.g., correcting a company name misspelled throughout the transcript).
Unique: Implements transcript editing with full version history and user attribution, enabling compliance-grade audit trails of transcript changes while supporting bulk find-and-replace and diff-based review
vs alternatives: More robust version control than Otter.ai's basic editing, but less automated than Fireflies.io's AI-assisted correction suggestions
Exports transcripts in multiple formats: plain text (.txt), Microsoft Word (.docx), PDF, JSON (structured with speaker labels and timestamps), SRT (subtitle format for video sync), and CSV (for spreadsheet analysis). The export pipeline handles format-specific requirements: PDF includes formatting and page breaks, Word documents preserve speaker labels and timestamps in a table, JSON maintains full metadata, and SRT generates subtitle timing for video players. Users can customize export options (include/exclude timestamps, speaker labels, summary, action items) before generation.
Unique: Supports multi-format export (text, Word, PDF, JSON, SRT, CSV) with customizable options for timestamps, speaker labels, and summaries, enabling transcripts to be shared across diverse tools and workflows without manual reformatting
vs alternatives: More export format options than Otter.ai's basic text/PDF, but less integrated with downstream tools than Fireflies.io's direct Slack and email sharing
