Compress massive AI sessions into portable memory capsules. 100% client-side.
VantaCore turns long chats, dev logs, research notes, and knowledge-base material into LLM-ready memory capsules that preserve final state, decisions, open loops, commands, artifacts, and do-not-repeat constraints.
Same merged multi-session AI export, now compressed into a structured Memory Capsule.

VantaCore is a client-side compression and Memory Capsule engine for LLM continuity. It is built for:
- AI chat continuation
- RAG / Knowledge Base preparation
- Dev logs and coding-agent sessions
- Research notes
- API/token cost reduction
- MCP and agent workflows
It is not a generic summarizer or text shortener. The goal is continuity: help the next model know what happened, what was completed, what remains open, what decisions were made, and where to continue.
- 100% client-side browser processing
- Paste text or upload
.txt,.md,.json,.csv,.log - Memory Capsule output with session map, final state, open loops, decision log, reference dictionary, and compressed detail stream
- Approximate token estimates
- Code block protection
- Clusters / refs / folds metrics
- 5 local compressions per day
- Last 20 local history entries stored only in browser storage
- Branded free exports for TXT/MD/JSON
VantaCore does not claim ownership of your input or output content. Free exports include VantaCore attribution as the generator of the memory-capsule format.
Core principle:
Free core. Paid power.
The free web demo stays useful, private, and client-side. Future Pro tracks are planned for power users and developers:
- CLI workflows
- MCP server tools
- batch/folder compression
- compression profiles
- advanced export formats
- project/workspace history
- no-branding exports
- API later, after CLI/MCP validation
No signup, backend, cloud sync, payment, or API is required for the current free demo.
