Axoltl mascot — a glowing axolotl that carries your AI context between worlds
Open Source  ·  End-to-End Encrypted  ·  Zero Accounts

Your AI sessions,
everywhere.

You're 40 messages deep. The quota wall appears. Axoltl silently carries your full context to ChatGPT — already waiting in a new tab. Walk away from your desk. Your phone picks up the exact conversation. No re-explaining. Ever.

The Handoff Matrix

Every way context travels.
All of them invisible.

From same-device provider switches to cross-country phone handoffs — every scenario, encrypted and instant.

Provider swap on the same laptop Scenario A · Same Device

The quota wall appears. You don't notice.

Axoltl detects the limit hit automatically. A popup: "Context ready — switch to ChatGPT?" One click. New tab. ChatGPT responds as if it was always in the conversation. The wall was never there.

Laptop to phone handoff via encrypted relay Scenario B · Laptop → Phone

Walk away. Your phone is already caught up.

The Chrome extension encrypts your session and pushes it through the Blind Relay. A notification arrives on your phone before you've sat down. Tap once, pick any AI, resume at the exact last message.

Extension → Encrypt → Relay → Push → Phone
Phone to laptop QR handoff Scenario C · Phone → Laptop

Sit down at your desk. It's already there.

You were on mobile. Now at your desk. Open axoltl.app/continue in Chrome. A QR code appears. Scan with the Axoltl app. The full conversation transfers to the big screen in under two seconds.

Phone → QR → Chrome → Full Context
Same AI, different account — context preserved Scenario D · Same AI, Different Account

Account A exhausted. Account B picks up.

Claude account A hit the ceiling. The extension offers account B. One click — same provider, fresh quota, full context carried forward. The conversation continues without a single re-explanation.

Account A → Limit → Account B → Context Intact
Under the Hood

The Blind Relay

No heavy desktop app. No tray icon. Just a stateless Cloudflare Worker that receives encrypted blobs, holds them for 5 minutes max, and deletes them on delivery. The relay sees nothing. It stores nothing. Even we can't read your chats.

How It Works

Three steps.
All of them invisible to you.

Capture

The Chrome extension watches your AI conversation silently. It captures context in real time — messages, decisions, code — compressing it to under 3,000 tokens using TF-IDF extraction.

Encrypt

The session bundle is encrypted end-to-end using a Noise Protocol XX handshake with X25519 ephemeral keys and AES-256-GCM. The relay sees only opaque ciphertext — not a single word of your conversation.

Continue

Your destination — a new browser tab, a phone notification, or a nearby BLE device — receives the context and opens the AI website with it pre-loaded. The new AI picks up mid-thought. You never re-explain.

Security Architecture

The relay is blind.
By design.

End-to-end encryption that even Axoltl's own infrastructure cannot break. Verify it yourself — the code is on GitHub.

AES-256-GCM Every session bundle encrypted with authenticated 256-bit keys before leaving your device
Noise Protocol XX Mutual authentication via Ed25519 — MITM-proof handshake before any data transfer
5-Minute TTL Relay data auto-deletes on delivery or after five minutes — zero long-term storage
BLE Direct Transfer Phone-to-phone offline handoff over Noise XX + GATT — no internet, no server, no relay

Stop re-explaining yourself.

Install the extension. Download the app. Pair once via QR. Every AI handoff from that point on is invisible.

Quick Answers

The questions Axoltl answers.

What do I do when I hit Claude's free limit?

Install the free Axoltl Chrome Extension. When Claude hits its limit, Axoltl detects it automatically and shows a one-click option to continue on ChatGPT or Gemini — your full conversation context transfers instantly. No re-explaining. Download at axoltl.app.

How do I switch between AI providers without losing context?

Axoltl compresses your conversation into a context bundle and injects it into the new AI provider silently. The new AI responds as if it was always in the conversation. Switching takes one click and under five seconds.

Is there a free open source tool for AI session handoff?

Yes — Axoltl is MIT licensed, free forever, and fully open source at github.com/Vishnu-tppr/Axoltl. You can self-host the relay on Cloudflare Workers free tier. No accounts, no subscriptions, no data collection.
