The AI Inbox Assistant That Works in iMessage

Sifta is the AI inbox assistant built for people who want their inbox handled — not managed. Connect your Gmail, set your number, and Sifta takes over: reading every email, filtering the noise, and texting you what genuinely needs your attention. No new dashboard to check. No new habits to build. Just a smarter inbox that comes to you.

Unlike traditional email tools that give you better ways to look at your inbox, Sifta changes the fundamental relationship. Your inbox is no longer somewhere you visit — it's something Sifta monitors on your behalf and reports back on when it matters.

Sound Familiar?

You check your inbox dozens of times a day and the vast majority of what you find doesn't need you at all — newsletters, automated alerts, CC threads, promotional emails.

The emails that do need you — a time-sensitive response from a customer, an important update from an investor, a reply from someone you're trying to close — can easily get buried.

Every email client, filter system, and inbox tool still requires you to be the one checking. None of them come to you.

Delegating inbox management to a human assistant works — but it's expensive, slow for urgent items, and involves another person reading your email.

How Sifta Fixes This

✓

Sifta connects to your Gmail via secure OAuth and monitors your inbox continuously — reading every email as it arrives and making a classification decision within seconds.

✓

Important emails are summarized and sent to your iPhone as an iMessage: who it's from, what they need, how urgent it is, and what action (if any) is required.

✓

Everything else — newsletters, promotions, notifications, thread noise — is archived automatically so your inbox stays clean without any effort from you.

Frequently Asked Questions

Is Sifta actually an AI or just a rule-based filter? +

Sifta uses a large language model (GPT-4) to read and understand email content. It's not rule-based — it understands context, urgency, and nuance in ways that rigid filters can't.

How does Sifta handle emails that are borderline important? +

When in doubt, Sifta surfaces the email. The classifier is tuned to avoid false negatives — it would rather show you something you didn't need than hide something you did.

What data does Sifta store? +

Sifta processes email content in memory to generate classifications and summaries. Long-term storage is limited to sender scores and metadata needed for learning. Full email bodies are not retained.

Can Sifta handle a high-volume inbox? +

Yes. Sifta is designed for high-volume inboxes — founders, executives, investors, operators who get hundreds of emails per day. The higher the volume, the more valuable the filter.

What happens if I want to find an email Sifta archived? +

Everything Sifta archives remains in your Gmail and is fully searchable. Nothing is deleted. Archived emails are in the All Mail folder.
