ShareBolt is the world's first agent-to-agent file sharing platform. Send files from your phone to a Linux server, between two AI agents, or across enterprise pipelines — zero-knowledge encrypted, with no file size ceiling and no middleman storing your data.
Every competitor stores your files on their servers. ShareBolt encrypts before upload — your files never exist in plaintext outside your device.
iOS, Android, Windows, macOS, Linux, and Web — every platform can send and receive. No local network or OS-specific limitations. No ecosystem lock-in. One transfer protocol, every device.
See all platforms →Autonomous AI agents (Claude, GPT, Gemini, custom LLMs) can securely exchange files using Ed25519 DID identities, directory sandboxing, and cryptographic audit trails. The only protocol purpose-built for LLM pipelines.
See agent protocol →Connect your own S3, R2, or GCS bucket via Bring Your Own Storage (BYOS). ShareBolt encrypts before writing — your 500GB RAW footage and 40GB model weights transfer identically to a 10KB text file.
How BYOS works →AES-256-GCM encryption runs entirely on your device. Encryption keys are derived locally using HKDF-SHA256 and never transmitted to our servers — not even in transit. We literally cannot read your files.
Read the crypto spec →Files route through Cloudflare's global edge network — no central server, no VPN required. Send from a hotel WiFi in Tokyo to an agent running in Frankfurt, with GDPR edge residency respected automatically.
How routing works →Every transfer is recorded in a tamper-evident chain ledger (SHA-256 block hashes). Compliance teams get a complete, uneditable record of who transferred what, to whom, and when — for SOC2, HIPAA, and GDPR audits.
Inspect live ledger →From autonomous AI pipelines to enterprise legal teams to indie developers — one platform handles every file sharing need.
LLM agents (Claude computer-use, GPT Code Interpreter, custom pipeline workers) exchange model outputs, datasets, and audit logs using cryptographic DID identities and sandbox quotas.
AI agent solutions →Legal and HR teams transfer discovery documents, employee records, and financial exports under GDPR, HIPAA, and SOC2 requirements — with automatic edge residency routing.
Enterprise solutions →Video studios sending 400GB RAW cuts, ML teams shipping 40GB model weights, and genomics labs moving terabyte sequencing data — all with no size cap via BYOS storage backends.
How unlimited BYOS works →Drag any file to see client-side AES-256-GCM encryption, HKDF key derivation, and the transfer pipeline — live in your browser.
No other file sharing service offers zero-knowledge encryption AND unlimited file sizes AND agent-to-agent protocol support.

A full technical breakdown of how ShareBolt's Ed25519 DID system enables autonomous agents to securely exchange files with sandbox quotas and audit trails.
Why legacy OS-specific and cloud storage solutions fail the cross-platform test — and how ShareBolt's edge-native architecture solves every device combination.
How connecting your own S3, R2, or GCS bucket gives you unlimited file transfers while ShareBolt handles encryption — without ever seeing your data.
