A desktop email client for autistic and ADHD professionals

Every answer shows its source.

What they want. By when. Whether to reply. Simply states it and highlights the exact words it came from. Before you send, it shows how your reply will likely read.

From the email

The deck is due to Priya on Friday, so ideally I'd have them by Thursday.

Simply says

Deadline

Thursday Stated 6

"Ideally" is politeness. The deck is due Friday, so treat Thursday as the deadline.

What it does

Three things, done carefully.

01

Decode

Every email opens already decoded: what they are asking, the deadline, whether a reply is needed, and how the tone reads. Each line points to the words it came from. When Simply is unsure, it says so.

02

Tone Check

Before you send, see how your reply will likely read. Phrases that may be misread are flagged, each with the reason. Suggested edits appear as a diff you accept or reject. Direct is a setting, not a fault.

03

An inbox that waits for you

No unread counts, no red badges, nothing that moves. The Simply app connects to the Gmail or Microsoft 365 account you already have. Your address stays the same and there is nothing to migrate.

One email, read line by line.

    "Just a thought" may mean a recommendation she expects you to consider. The email does not say. When Simply is unsure, it says so.

Tone Check

Check a reply before it goes.

Write the reply your way, then check it. Simply explains and suggests. It does not rewrite anything unless you accept the edit, and it confirms that the facts and commitments stay the same.

No, I can't do Thursday. The data won't be ready until Monday. I can send it Monday afternoon.

Notes, not errors

Likely reading

Clear and accurate. Starting with "No" and having no greeting may read as abrupt to some managers.

Flags

  • No, I can't A flat refusal as the opening can feel like pushback. Optional.
  • No greeting or sign-off Fine for quick threads. With a manager it can read as rushed.

Suggested version

Hi Dana, No, I can't do Thursday. The Thursday won't work, since the data won't be ready until Monday. I can send it Monday afternoon. Thanks, Sam

  • Add a greeting AcceptReject
  • Lead with the reason AcceptReject
  • Add a sign-off AcceptReject

Meaning unchanged Thursday is still declined. Monday afternoon is still the commitment.

Privacy

Private by default.

Email is sensitive. So is the fact that someone uses this tool.

Your email is never stored on Simply's servers. Text is sent for analysis only when needed, and it is not kept.

  • Your mail stays on your own computer, in an encrypted database.
  • Nothing in the mail you send shows that you use Simply.
  • This site has no tracking, no analytics and no third-party fonts.

Founder

Built by an autistic and ADHD founder.

Darren, the founder of Simply

I'm a software engineer, and I overthink every email I send. People have still told me my short replies come across as cold or careless. I'd been careful; the care just didn't make it into the words.

Reading is hard too. A crowded inbox overwhelms me. I miss cues other people seem to catch, and I can spend far too long working out what someone actually meant.

Simply is the tool I wanted. It says what an email means and shows the evidence. It checks how my reply will land before I send it. The decision stays with me.

I'd rather build it with people who have the same problem than guess.

Darren, founder

Join

Join as a design partner or the waitlist.

Design partners try early versions and say what is wrong with them. In return, they use the Simply app free during the beta and for the first year after launch. After that, they keep a lower founding price for as long as they stay subscribed. The waitlist gets one email when Simply is ready to try.

  1. You get one email with a link to confirm. The link works for 7 days.
  2. Design partners: I write to you myself before the first round of sessions. No date is set yet.
  3. Waitlist: you get one email when there is a version to try.
  4. Every email has a link that removes your entry.

How many email accounts you check

Work and personal both count.

How you want to take part
Design partners: how you want to give feedback

Both count equally. Questions are sent in advance either way.

Neurotype (optional)

Optional. It is stored encrypted and separately from your email address. It is used only to invite a mix of testers. It is deleted when your entry is deleted.

Next, you get one email with a link to confirm. Entries that are not confirmed are deleted after 30 days. Privacy
