A FIELD NOTE · WHO WE ARE · WHAT WE'RE BUILDING

Not another inbox.
One that reads with you.

VectorMail is a thin intelligence layer over the Gmail account you already have. It sits next to your inbox and helps you decide what to read, what to reply to, and what to ignore.

PRODUCT

What VectorMail is - an intelligence layer, not a replacement.

VectorMail sits next to the Gmail account you already use. It reads with you, drafts in your voice, and finds the thread you half-remember.

  • An intelligence layer that sits on top of Gmail through Aurinko
  • Threads sync into PostgreSQL with embeddings stored in pgvector
  • AI summaries, drafts, and search run against your own indexed mail
  • Works alongside Gmail; we don't replace your underlying account

MOTIVATION

Why we built it - search is still keyword. AI is still over-eager.

Most email clients pretend it's 2008. Most AI features pretend you wanted them to send the email for you. We wanted neither.

  • Most email clients still treat search as keyword lookup
  • Most AI features replace the user instead of helping them decide
  • Sending and reading remain separate from organizing and finding
  • We wanted one workspace where all four happen at the same desk

How it's built - small surface area, durable parts.

Next.js on the front. Postgres + pgvector for storage and recall. Aurinko for sync. Inngest for jobs. OpenRouter and Gemini for the AI. That's the whole picture.

  • Next.js 15, React 19, and Tailwind on the front end
  • tRPC and Prisma against PostgreSQL with pgvector for search
  • Aurinko for Gmail sync, Inngest for background jobs
  • OpenRouter for chat completions, Gemini for embeddings

DATA POLICY

How we handle your data - account-scoped, encrypted, deletable.

Your mail is yours. Nothing crosses accounts, nothing trains shared models, and hard-deletes are real.

  • Mail is account-scoped; nothing crosses between users
  • Tokens are stored encrypted and revocable from Google
  • Embeddings and summaries are deleted when the account is removed
  • We do not use your mail to train shared or public models

LETTER FROM THE WORKBENCH · MAY 2026

Where we are - honestly.

ectorMail is in active beta. The core sync, search, and reply pipelines are stable; the daily brief and intent classifier are still maturing.

We ship behind a small, vetted user list while the product hardens. If you want access, send a note. We'll get back the same week.

Updates land in the changelog. Material changes to data handling go in the privacy policy with the date of the change.
