Stop rewriting the same email.
InboxOji learns the messages you answer over and over — quotes, scheduling, invoices, the same questions every week — and drafts each reply in your voice, waiting in your inbox. You choose which emails to automate. You approve what gets sent.
Connect in 30 seconds. Cancel anytime. We never sell or train AI on your data.
I get the same fifteen kinds of email all day. InboxOji drafts the replies in my own words — I just skim and send. It's the first AI tool that didn't make me sound like a robot.
Setup took ten minutes. It read my inbox, suggested the rules, and by lunch it was drafting my scheduling replies for me.
What sold me was the control. It only handles the repetitive stuff I told it to — everything else in my inbox is untouched.
Our whole support team now answers in one consistent voice, and I get hours back every week. The drafts are genuinely good.
Not a bot that answers all your email.
Most AI email tools try to reply to everything — which is exactly why people don't trust them. InboxOji is the opposite: controlled automation. You pick the repetitive emails worth handling, and it drafts only those, in your voice. The rest of your inbox stays untouched.
Blanket AI auto-responders
- Try to answer every message
- Generic "AI voice" that sounds nothing like you
- You lose track of what was sent
- One wrong reply and you turn it off for good
InboxOji
- Handles only the repetitive emails you choose
- Writes in your voice, and learns from your edits
- Every reply is a draft you review and approve
- Auto-send only on the rules you've tested and trust
See what your repetitive email really costs.
Most inboxes are full of the same few replies on repeat. Here's a rough idea of what InboxOji could give back.
Estimate only — assumes a $30/hr cost of time and that InboxOji drafts these replies for you to review.
Up and running in three steps.
No new app to learn. InboxOji works inside the inbox you already use.
Connect your inbox
Securely link your inbox in seconds. Your connection is encrypted, we never see your password, and we never store the contents of your mail.
Tell it what you reply to
Set rules for the emails you handle often — or let InboxOji read your recent inbox and suggest a few to start from. It learns your voice as you go.
Approve and send
Drafts wait in your inbox, written in your words. Review and send with a click — or auto-send the rules you've tested and trust.
Built to sound like you — and stay under your control.
In your voice, not "AI voice"
It writes each reply from scratch in your tone — and gets sharper every time you edit a draft.
Smart enough to pick the right reply
One rule can cover many situations — InboxOji reads each email and drafts the response that fits, or nothing if none do.
Set up in minutes, not hours
It reads your recent inbox and suggests ready-made rules — so you're drafting in minutes, not staring at a blank screen.
Replies grounded in your facts PRO+
Attach your pricing, policies, or FAQs and InboxOji pulls in the right details — accurate, not just fluent.
Your engine, your choice PRO+
Starter runs on Claude Sonnet. On Pro and up, pick Claude Opus, Haiku, Fable, or OpenAI's GPT.
See where your time goes
A clear dashboard shows replies handled, hours saved, and cost recovered — by rule and by week.
It works inside your inbox
Drafts land in your normal drafts folder, on every device. Gmail today; Outlook coming soon.
Made for teams ENTERPRISE
Company-wide rules, a shared knowledge base, seats, and an admin console — one consistent voice, centrally controlled.
Encrypted and yours alone
AES-256 encryption, data isolated from every other account, and you can disconnect anytime. More on security.
Security isn't a feature. It's the foundation.
InboxOji connects to one of the most sensitive systems you own. We treat it that way — starting with the things that matter most: you stay in control, and your email is never read, sold, or used to train AI.
You approve every send
Every reply is a draft until you send it. Auto-send only ever applies to rules you've explicitly tested and switched on — and you can pause it instantly.
Never sold, never trains AI
Your email is used to draft your replies and nothing else — never sold, never shared for ads, and never used to train AI models.
Encrypted access, always
Your inbox connection is protected with AES-256-GCM encryption and decrypted only inside our secured backend — never in your browser, never in plain text.
Walled off from everyone else
Every account's data is isolated at the database level. Your rules, inbox, and history are visible only to you — verified, not just promised.
Two-factor authentication
Add TOTP-based 2FA on any plan. Passwords are hashed and screened against known breaches, with security alerts on sensitive changes.
Minimal data by design
We don't store the contents of your emails. Your activity log keeps only metadata — sender, subject, and a one-line reason — so there's less to ever expose.
Simple pricing that scales with you.
Start solo, upgrade when it pays for itself, and bring in your team when you're ready. Every plan is built on the same secure foundation.
