Conversation Threads

Just reply to keep the conversation going. Byte remembers context for 30 days per thread.

Works Everywhere

Phone, laptop, tablet, smartwatch — if it sends email, it works with Byte. Zero setup required.

Why Is This Free?

Byte is a community service project. Not a product. Not a startup. We built this because AI should be accessible to everyone — not locked behind apps, accounts, and paywalls.

“If you can send an email, you can use AI. That's the whole point.”

No data selling. Your emails are processed and forgotten. Conversations auto-delete after 30 days.

No hidden costs. No premium tier, no “upgrade to unlock” tricks. What you see is what you get.

Transparent about the future. We may introduce helpful, relevant suggestions down the road to keep the lights on — but they won't be the spammy kind, and we'll let everyone know well in advance.

This is built for the community, by the community. Your feedback shapes what Byte becomes.
