Your inbox organizes itself.
Every system you set up dies the day you stop maintaining it. This one has nothing to maintain.
You maintain it
Back where you started.
Ada maintains it
Digest at 8:00. Nothing to catch up on.
You approve once and clean up never. When you want something different, you reply to the digest.
Postcards from calmer inboxes.
“As someone with ADHD that tends to worry about missed emails, it has been a tool that has changed my email life. Thanks for making something that helps people like me!”
“I have extremely intense ADHD and MailSynth has been a GIANT breath of fresh air! The price is fair too! I plan on using MailSynth for a long time.”
“So far it’s amazing. The labels make it so much easier to clean out the rubbish!”
“It has been an absolute lifesaver. I no longer feel overwhelmed when viewing my emails.”
“I was about to write a tool similar to this for personal use. But now I don't have to… I love the email conversations with MailSynth, and especially love the focus on ADHDers.”
“I really love how much you have helped my crazy mess of a mailbox. As I live with ADHD this really helps my head focus when checking my mail.”
Designed for the ways ADHD breaks email.
Not a productivity app you have to keep up with. Each part of MailSynth exists because of a specific thing ADHD does to an inbox.
Out of sight, out of existence.
An email you scroll past stops existing until it turns into a late fee.
Priority 1 mail stays in your inbox for 30 days and sits at the top of the digest while it's there.
Open Gmail for one thing. Lose forty minutes.
The inbox is a slot machine. You go in for a tracking number and come out with a new anxiety.
The digest brings the day to you, once, at a time you pick. You open Gmail when there's a reason, not to check.
Set up folders once. Never touch them again.
Sunday afternoon, twelve folders, real optimism. By Wednesday the folders are a museum.
Ada labels, sorts, and archives every day. The system runs whether you look at it or not.
Deciding what matters is the hard part.
Every email arrives at the same volume. Triage is the work, and triage is what's broken.
Ada proposes priorities 1, 2, and 3 for your inbox. You approve, and change any of it by replying in plain English.
4,000 unread and a shame spiral.
The number is so big it stops meaning anything, so you stop looking.
Clutter auto-archives on a schedule you approved. Your inbox goes back to a number you can look at.
You read the newsletter. You did not read the bill.
Interesting beats important every single time.
Bills and doctors rank above newsletters in the digest, and newsletters get a summary so skipping them costs nothing.
No data sharing. No AI training. Yours alone.
MailSynth reads your inbox to organize it. Here is exactly what that means.
Read by AI, never by a person.
The AI that labels your mail is contractually barred from keeping it or training on it. Servers are in the U.S.
Never sold. Never used for anything but your inbox.
You pay for MailSynth, so your data is not the product.
Cancel, and we delete our copy.
Your labels stay in Gmail. Everything we stored is deleted.
One plan. Nine dollars a month.
One inbox is $9 a month. Each extra inbox is $7. The first 30 days are free, no card required.
One inbox, plus tax where it applies.

Things people ask before they sign up.
No. Sign in with Gmail and Ada proposes a system from your inbox. You approve it, and that's the setup. There's no app to install and nothing to configure. When you want something changed later, reply to the digest in plain English.
That's the fear the whole thing is built around. Priority 1 mail stays in your inbox for 30 days and sits at the top of the digest. Nothing is deleted, ever. Archived mail is one search away.
Gmail only, for now.
Sell, never. Store, barely. Your emails stay in Gmail. We don't copy them anywhere. We keep only your preferences, summaries, and labels, and delete them if you cancel. Nothing is used to train AI models.
No. Ada uses ordinary Gmail labels and archives clutter on the schedule you approved. Archived mail is still in Gmail, still searchable, one click away.
Reply to the digest and say so. "Put Boxline Shipping under Deliveries" or "newsletters are priority 3". Ada shows you the exact changes, you say yes, and it's done.
Fine. Ada starts with recent and incoming mail and works back through the rest over time.
Yes, from the Account tab in the web app. No hidden menus, no retention maze. Your labels stay in Gmail, and everything MailSynth changed can be reverted.
$9 a month for one inbox, and $7 a month for each additional inbox. The first 30 days are free, no card required.
It's built for ADHD first. Plenty of people without a diagnosis use it too, because keeping up with email admin isn't a problem exclusive to us.
For us, ADHD was never a focus problem. It was a paperwork problem.
We have ADHD. The three of us who build MailSynth, most of the advisors who shaped it, and the community that tells us when we get it wrong. We built this because the paperwork of adult life kept beating us. Not the big stuff. The bills, the renewals, the forms, the follow-ups. Things that should take ten minutes and instead take three weeks and a late fee.
Most of the world runs on admin, and admin is exactly what our brains refuse to do. So we built something that does it for us.
The goal isn't productivity. It's getting people out of the paperwork prison so their energy goes to the things they're actually good at. Long term, we want to move the numbers that matter: the money ADHD costs people, and the years it costs them.
Gmail, fixed. Thirty days to see for yourself.
Free for 30 days, no card required. Ada builds your system, then keeps it running.
