How ThreadCrunch works — from forwarded email to shareable link

ThreadCrunch turns email threads into clean, readable URLs. Here's the full flow:

Sharing a thread:

1. Forward any email thread to share@threadcrunch.io

2. Our email worker receives it, parses the MIME, and splits it into individual messages

3. You get an email back with a clean URL — share it with anyone

AI analysis:

1. Forward to process@threadcrunch.io instead

2. Same parsing, but then the thread goes through Claude Sonnet for analysis

3. You get back: tone and intent per participant, key points, agreements, disputes, action items, and a draft reply

written from your perspective

4. Analysis costs $0.20 per thread on top of the $5/month base

Updating a thread:

Every thread comes with a unique update address. Forward a new reply to that address and the thread gets updated in place — same URL, new messages appended. If you've enabled AI analysis for this thread, analysis reruns automatically.

Export:

Every thread URL has .json and .md endpoints. Feed them straight into your own LLM tooling, documentation, or whateveryou need.

Threads auto-delete after 7 days. No accounts to manage, no browser extensions, no integrations to configure.
