Limitless

Interact with Limitless API

Actions3

Overview

The node interacts with the Limitless API to manage and summarize lifelog data. Specifically, the Summarize Day operation fetches lifelogs for a specified date and timezone, then uses an AI chat model to generate a concise summary of the day's events, activities, and key topics discussed based on those lifelogs.

This node is beneficial in scenarios where users want to automatically generate daily summaries from detailed lifelog transcripts, such as personal journaling, productivity tracking, or meeting notes summarization.

Example use case:
A user records various lifelog entries throughout the day (meetings, tasks, conversations). At the end of the day, this node fetches all those entries and produces a brief overview highlighting important points, saving time on manual review.

Properties

Name Meaning
Timezone IANA timezone specifier used to interpret the date parameter. Defaults to "UTC" if not provided.
Date The specific date (YYYY-MM-DD) for which lifelogs will be fetched and summarized.
Lifelog Limit Maximum number of lifelog entries to retrieve for summarization (default 100).
Prompt Custom prompt template for the AI summarization. Use {{$json.lifelogsText}} as placeholder for lifelog text.
Chat Model The AI chat model credential to use for generating the summary.

Output

The output JSON contains a single field:

  • summary: A string containing the AI-generated concise summary of the day's lifelogs.

No binary data is produced by this operation.

Example output JSON:

{
  "summary": "Today included meetings about project X, a brainstorming session on marketing strategies, and follow-ups on client feedback."
}

Dependencies

  • Requires access to the Limitless API via an API key credential.
  • Requires an AI chat model credential configured in n8n for summarization.
  • The node makes authenticated HTTP requests to the Limitless API to fetch lifelog data.
  • The AI summarization uses Langchain's LLMChain with a prompt template.

Troubleshooting

  • Missing Date Parameter:
    Error: "Date parameter is required for Summarize Day operation."
    Resolution: Ensure the "Date" property is set to a valid date before execution.

  • Missing Chat Model Credential:
    Error: "Chat Model credential name is required for Summarize Day operation."
    Resolution: Configure and select a valid AI chat model credential in the node properties.

  • API Request Failures:
    Errors during fetching lifelogs may occur due to invalid API credentials, network issues, or incorrect parameters.
    Resolution: Verify API key validity, network connectivity, and correct input parameters.

  • Unexpected Response Format:
    If the response from the API does not contain expected lifelog data, the node logs a warning and returns an empty summary.
    Resolution: Check the API endpoint and ensure lifelogs exist for the requested date.
