Todas tus IA,
recordando a la misma persona.

Start a project with Grok, continue it with ChatGPT, and keep your knowledge in one private vault. EleSync lets approved assistants read the context you choose — without making you explain yourself again.

Getting started

Three steps, then you forget it's there.

Install it, choose your vault, and start saving. Your information stays local, while approved AI tools use the context you choose.

Step one

Install it

Download for your computer and open it. Your vault opens in your browser — no terminal, no config files, no setup.

Step two

Bring your history

Bring in JSON, CSV, Markdown, ZIP archives, WhatsApp conversations, and AI exports. Review private content before it enters your vault.

Step three

That's it

Create a project or knowledge sheet, connect the AI you choose, and continue your work without repeating the whole story.

The dashboard

You can see everything it remembers.

Your vault opens in the browser — search it, edit it, organize it, and import new knowledge. It runs on your machine; remote access is optional and protected.

One local workspace. Search memories, review imports, organize projects, and manage AI access from the dashboard.
What it does

Small tool. Surprising amount of range.

All of it runs on your machine. None of it phones home.

Remembering

  • Move your history inBring across JSON, CSV, Markdown, ZIP archives, WhatsApp chats, or exports from ChatGPT, Claude, Gemini, Grok, Copilot, and more.
  • Review before savingPrivate conversations such as WhatsApp chats are previewed first, so you decide what enters the vault.
  • Finds what you meantOptional smarter search that turns up the right memory even when you word it completely differently.
  • Catches contradictionsWhen two assistants believe different things about you, EleSync shows you both — with who said what, and when — and you pick.

Staying in control

  • Decide what each AI seesLet one assistant read your writing notes but never your medical ones. You set the boundaries per assistant.
  • Let one look but not touchGive an assistant read-only access. It can use your memory; it can't change it.
  • Keep a recordEvery time an assistant reads, writes, or forgets something, it goes in a log on your disk. You can see exactly who did what.
  • Get the summaryOne view of everything your vault knows about you — handy before you start a new conversation.

Owning it

  • They're just filesNot a database you can't open. Plain text on your own disk, readable without EleSync, yours to take anywhere.
  • Lock it with a passphraseEncrypt the whole vault. Your assistants still read it live, and nothing readable ever touches the disk.
  • Carry it on a USB stickPlug it in on another machine and your memory comes with you.
  • Sync it however you likeIt's a folder — so iCloud, Dropbox, Syncthing, or Git all work. Encrypted vaults are safe to sync through services you don't trust.
  • Back up to the cloudCompressed, optionally encrypted archives push to S3, B2, GCS, Drive or SFTP via rclone — no cloud SDK, no account required.
  • Summarize with an LLMAsk a local Ollama model or OpenAI/Anthropic to digest a slice of your vault. Privacy warning before anything leaves your machine.
  • Leave whenever you wantExport the lot to CSV or JSON in one click. There's no lock-in to escape.

Living with it

  • Works with your AI teamClaude, Gemini, Grok, Perplexity, Copilot, ChatGPT, DeepSeek, and compatible local clients can use the vault you approve.
  • Organizes knowledgeKeep conversations, knowledge sheets, memories, and projects together without forcing everything into one category.
  • Private by designChoose what each assistant can access. Your full vault is never automatically shared with every AI.
  • Reach it from your phoneInstall the dashboard as a PWA and use the same local vault from your phone when your computer is running.
Privacy

Your data is yours. Full stop.

EleSync runs entirely on your computer. We can't see your memories, because they never leave it — that's how it's built, not a promise we're asking you to take on trust.

No accounts No telemetry No analytics No ads

Hardening

ELESYNC_AUDIT=1 turns on the append-only audit trail. ELESYNC_SCOPES=readonly:… makes a client read-only, enforced at the service layer rather than by convention.
