Sifta is an AI agent that automates your inbox so you never have to open it again.

Most people spend hours every week managing email scanning through spam, searching for what matters, worrying about what they missed. Sifta handles all of that for you. It connects to your Gmail or Outlook, stops the noise automatically, and texts you only the messages that need your attention.

When Sifta texts you, you can reply to take action. Tell it what you want in plain English and it handles it. No commands to learn. No app to download. No dashboard to figure out. Just a text back and it's done.

Your inbox runs in the background, fully automated. You stay focused on your actual work instead of living inside your email.

Works with Gmail and Outlook. Setup takes 2 minutes. $49/month.

s3-lambda features and specs

  • Batch processing of S3 objects
    s3-lambda provides a straightforward way to perform batch operations on large numbers of S3 objects, enabling map, filter, and reduce-style processing over entire S3 buckets or prefixes without writing boilerplate code.
  • Familiar functional API
    The library uses a functional programming paradigm with operations like map, filter, and reduce, making it intuitive for JavaScript developers to process S3 objects using patterns they already know.
  • Built-in concurrency control
    s3-lambda handles parallel processing of S3 objects with configurable concurrency, allowing users to control how many operations run simultaneously and avoid overwhelming AWS resources or hitting rate limits.
  • Context-aware operations
    The library provides a context object within each operation that includes useful metadata about the current object being processed, simplifying access to S3 object properties during transformations.
  • Easy integration with Lambda
    Designed to work seamlessly within AWS Lambda functions, making it straightforward to set up event-driven, serverless pipelines for processing large volumes of S3 data without managing infrastructure.

Possible disadvantages of s3-lambda

  • Unmaintained project
    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK versions.
  • Limited documentation
    The project's documentation is relatively sparse, lacking comprehensive examples, edge case handling guidance, and detailed API references, which can make it challenging for new users to adopt effectively.
  • AWS SDK version dependency
    The library depends on an older version of the AWS SDK for JavaScript, which may conflict with projects using the newer AWS SDK v3 and could miss out on performance improvements and features in updated SDKs.
  • Limited error handling flexibility
    The built-in error handling mechanisms are relatively basic, and handling partial failures or implementing sophisticated retry logic for individual object operations requires additional custom code from the developer.
  • Narrow scope of functionality
    The library is tightly focused on S3 object processing and does not integrate with other AWS services or provide utilities beyond basic map/filter/reduce operations, limiting its usefulness in more complex data pipeline scenarios.

Who are some of the biggest customers of your product?

Sifta's answer

What makes your product unique?

Sifta's answer

Every other email tool still requires you to open something. A new inbox, a new app, a new dashboard. Sifta is the only email product that removes your inbox from your daily routine entirely. It automates the whole thing in the background and gives you full control through iMessage. You never have to open Gmail again.

Why should a person choose your product over its competitors?

Sifta's answer

Superhuman makes your inbox prettier. SaneBox sorts email into folders. Fyxer summarizes what's in your inbox. All of them still require you to open something and do something. Sifta doesn't. You connect your Gmail or Outlook, and Sifta runs your inbox from that point forward. Spam stops. Important emails get texted to you. You reply to take action in plain English. No new behavior. No new interface. No new habit to build.

If you want a better inbox, use something else. If you want to stop living inside your inbox entirely, Sifta is the only product that actually does that.

How would you describe the primary audience of your product?

Sifta's answer

Founders, executives, lawyers, or any professionals who get 50 or more emails a day and can't afford to miss what matters. People whose time is worth more than their inbox management. They've tried other tools and still find themselves stuck inside their email.

What's the story behind your product?

Sifta's answer

Sifta was built around one idea: email should be completely automated. You shouldn't have to open it, sort it, or manage it. It should just run. And when something actually needs you, it should come find you not the other way around. That's what Sifta does.
