FusionLayer is the layer above every AI you use. It remembers across ChatGPT, Claude, Gemini, Cursor, and more; strips API keys and secrets before they leave your machine; and picks the cheapest model that can actually answer — so your cloud AI bill goes down, not up.
Works with 20+ AI tools • Zero-knowledge encryption • Cheaper than using AIs alone
Works with all your AI tools
Three steps. No workflow changes. FusionLayer does the rest in the background.
Browser extension, desktop app, or CLI. Works with Chrome, Firefox, Edge, VS Code, Cursor, and the command line.
Guided setup wizard. Plug in the AIs you use — Claude, ChatGPT, Gemini, Grok, DeepSeek, or local Ollama. Keep your existing subscriptions; FL uses what you already pay for.
Every question gets routed to the cheapest model that can actually answer. Secrets stripped on the way out. Cross-vendor memory on the way in. Fully encrypted throughout.
Every design decision starts with privacy. Every feature ships only when it's secure.
AES-256-GCM encrypted on your device. Keys derived via Argon2id — never transmitted. We cannot read your data even if we wanted to.
Chrome, Firefox, Edge, VS Code, Cursor, Windsurf, and CLI. One unified history regardless of which tool you used or which device you were on.
Analyze your AI usage patterns with Ollama running locally. Usage insights, topic trends, productivity metrics — all processed on your machine.
Point FusionLayer at your own S3, Cloudflare R2, Backblaze B2, or MinIO. Your encrypted blobs, your bucket, your cloud account. Pro plan.
Free tier keeps 90 days of conversations — enough for most users. Pro keeps everything, forever. No surprise deletions, no data hostage games.
UACP (Universal AI Context Protocol) — an open standard for AI conversations. Export anytime. Your data is portable forever, not locked in our format.
FusionLayer scans every message for API keys, JWTs, SSH keys, credit cards, IBANs, SSNs, and high-entropy secrets — and strips them before anything is stored, synced, or sent to a cloud AI. Mandatory baseline. Learn more →
Already have years of ChatGPT or Claude conversations? Point fl import at your official export and everything normalizes, redacts, and syncs. Start with a full library on day one. Learn more →
Bring your own keys for Claude, OpenAI, Gemini, Grok, and DeepSeek. FusionLayer picks the cheapest model that can actually answer and falls back instantly if a vendor is down — and routing runs after redaction, so secrets never decide where your traffic goes.
An API key in a prompt becomes a row in a vendor database. FusionLayer stops that — before capture and before injection into any cloud AI.
[REDACTED:<kind>] placeholdersYour AI history lives in vendor silos. Request your official export, point FusionLayer at it, and everything becomes searchable, encrypted, and yours — with secrets stripped on the way in.
