Limitless

Captures audio and conversation data from multiple input sources including native app integrations (Zoom, Teams, Google Meet), optional wearable device streaming, and direct application APIs. Uses background audio processing with automatic source detection to route conversations to appropriate transcription pipelines based on platform-specific metadata and codec support.

Converts captured audio to text using streaming transcription APIs with automatic speaker identification and turn-taking detection. Processes audio chunks in real-time or near-real-time, maintaining speaker context across conversation segments and handling overlapping speech through diarization models that identify distinct speakers without explicit labeling.

Generates abstractive summaries of recorded conversations using large language models with access to full transcripts, speaker metadata, and optional meeting context (calendar title, attendees, agenda). Applies prompt engineering and few-shot examples to extract key decisions, action items, and discussion topics while preserving speaker attribution and temporal structure.

Indexes transcribed conversations using vector embeddings (semantic search) and traditional full-text search, enabling users to find past discussions by meaning rather than exact keyword matching. Stores embeddings in a vector database with metadata (speaker, timestamp, meeting context) and supports hybrid search combining semantic similarity with keyword filtering for precise retrieval.

Aggregates recorded conversations from multiple sources (Zoom, Teams, Slack, email, wearable) into a unified timeline indexed by timestamp and participant. Deduplicates overlapping recordings (e.g., same meeting captured from multiple devices) and correlates related conversations across platforms using participant matching and temporal proximity heuristics.

Parses transcripts and summaries to identify action items, commitments, and decisions using NLP pattern matching and LLM-based extraction. Extracts task description, implied owner (speaker who committed), deadline (if mentioned), and priority, then optionally integrates with task management systems (Notion, Asana, Linear) to create actionable items without manual entry.

Offers on-device recording and transcription options that keep sensitive audio and transcripts local rather than sending to cloud APIs. Uses local speech-to-text models (Whisper, etc.) and optional end-to-end encryption for cloud storage, with user control over which conversations are processed locally vs. cloud-based for performance tradeoffs.

Integrates with compatible wearable devices (smartwatches, AI pins, glasses) to capture ambient conversations and background audio without explicit app activation. Handles battery optimization through intelligent recording scheduling, audio compression, and periodic syncing to phone/cloud, with user controls for when recording is active (e.g., during work hours only).

Automatically enriches recorded meetings with metadata from calendar systems (meeting title, attendees, agenda) and optional CRM integration (customer name, account, deal stage). Uses this context to improve summarization, action item extraction, and search by understanding meeting purpose and participant roles without manual annotation.

Analyzes aggregated conversation history to identify frequently discussed topics, common questions, and recurring explanations, then automatically generates knowledge base articles and FAQ entries. Uses clustering and topic modeling to group related conversations, extracts representative answers from transcripts, and creates searchable documentation without manual authoring.
