Knowledge that compounds

Give your AI a
permanent memory

AI forgets everything after each chat. Synapse connects it to your notes so knowledge compounds. Save articles, ask questions, build a brain — from your phone, laptop, anywhere.

The Problem

AI with amnesia

Every chat starts from zero. You explain the same context, re-share the same docs, re-teach the same preferences. Nothing compounds.

Context lost daily

Close a chat, the knowledge disappears. Tomorrow you start over. Weeks of conversations, gone.

Copy-paste loops

Manually pasting articles and notes into every new conversation. Your AI can’t access your files.

Knowledge silos

Research on your laptop. Ideas on your phone. Notes in Obsidian. Your AI can’t see any of it.

How It Works

Four operations, one growing brain

Synapse connects your AI to your notes. Every interaction makes the knowledge base smarter.

01 — Save

Capture anything

Save articles, research, ideas from any device. Share a URL or paste content.

“Save this article to my vault: https://example.com/ai-trends”

02 — Compile

Build the wiki

Raw sources become structured knowledge — summaries, concept pages, entity pages, all cross-linked.

“Compile my knowledge base”

03 — Query

Ask questions

Research across everything you’ve saved. Get cited answers. Every answer feeds back into the wiki.

“What do my notes say about pricing strategy?”

04 — Maintain

Health check

Find contradictions, broken links, orphan pages, stale content. Fix what it can, flag the rest.

“Run a health check on my vault”
