You subscribe to newsletters for a reason. Curated insights, expert analysis, industry news. But how often can you actually find that article you read three weeks ago?

Newsletter-to-knowledge conversion solves this. Your subscriptions become a searchable archive.

Feature Overview

Newsletter-to-knowledge converts your email newsletter subscriptions into a searchable knowledge base. Set up auto-forwarding and each newsletter issue is processed, indexed, and made retrievable by keyword, semantic search, or Q&A. Never lose a newsletter insight again.

The Newsletter Problem

Valuable but Ephemeral

Newsletters contain curated insights from experts you trust. But in email form, they're ephemeral. Read once, buried forever.

Impossible to Search

You remember reading something relevant. But which newsletter? Which issue? Email search can't help if you don't remember exact words.

No Cross-Source Queries

You subscribe to five newsletters on the same topic. Searching across all of them for related insights? Not possible in email.

The Solution: Auto-Archive
