The Claude build specification is at encrier.com/spec.html

encrier
The inkwell for your AI conversations. One URL saves your entire Claude chat as a portable file.
encrier.com type this in any Claude chat

How it works

Three steps. No install.

1
Chat with Claude

Strategy, code, writing, research — whatever you're working on.

2
Type encrier.com

Claude reads this page, gets the instructions, and builds your save file.

3
Download the HTML file

Open it in any browser to read the conversation, or upload it to a future Claude chat to pick up where you left off.

Your conversation becomes a portable save state — a checkpoint you can fork, share with teammates, or load six months later with full context.


Use cases

What you can do with a save state

→ Continue later

Upload the HTML to a new Claude chat and say "read this and pick up where we left off."

→ Share with anyone

Email the file to a colleague. They upload it to their own Claude session and have full context instantly.

→ Fork into branches

Upload the same save state to multiple chats, each exploring a different direction.

→ Version your thinking

Save at the end of each session. Build a chain of checkpoints you can go back to anytime.


Tips

Getting the most out of encrier

※ File creation must be enabled in your Claude chat for this to work. If Claude says it can't create files, check your settings.
※ For the most reliable trigger, type read encrier.com rather than just the bare URL. The word "read" ensures Claude fetches the page.
※ Best used as your last message in a session. The save state generation takes up context space, so treat it as a closing step.
※ Name your files with versions: project-v1-pricing.html, project-v2-corporate.html, etc.
※ Uploading back to Claude works best if you rename the file to .txt before uploading, as some upload pipelines handle HTML files inconsistently.
