Week one is the landing page. Week two is validation. Nothing ships before the reading view feels right.

Every one of these is a real file on your Mac, rendered locally, still a .md you can hand back to AI.

Find it. Read it.
Send it back.

Machines write Markdown. Humans read it. Here are the three moments in between, and what they feel like now.

Where did it even save this?

Claude says /tmp/. Claude Code says ~/.claude/plans. Five minutes in Finder, every time.

1FIND IT

Type part of the name. Or paste the messy path.

Quotes, ~/ and :142 on the end are fine. The file your AI just made is already waiting in Latest from your AI.

Is this a table or a fence?

Pipes and dashes are not a table. Your eyes know it, and they check out halfway across the row.

2READ IT

It opens as a clear page. Tables and all.

Real headings, tables that line up and diagrams in colour. Pick a reading profile, or press Read aloud and just listen.

I just need to change one line.

Copy it into Notion, fix the date, copy it back, hope nothing broke. For one date.

3SEND IT BACK

Fix it right here. Or send your notes to your AI.

Change a line and it saves to the same file. Leave notes as you read, then send them all in one message. See what changed, then save it as Word or PDF.

Everything stays on your Mac. No account, nothing uploaded.works with Claude, ChatGPT, Cursor and Codex
your eyes, your rules

Every heading, styled the way you read.

Pick a reading profile and a look. Neuro-friendly, Large Print, Compact and Paragraph Focus are all free.

MAKE THE PAGE FIT YOU
Reading profile

The standard page: lighter headings and generous spacing.

Colours

Every theme styles the title, headings, lists and tables for you. Pro adds 27 more themes and your own.

Priorities

Ship name search first, then reading profiles. Keep the reader fast on big files, and check the launch notes before Friday.

  • Search by part of a file name
  • Readable tables with status colours
  • Profiles people can name and share
Risks

Notarising can take a day. Book it early, and keep a build ready for review.

a confession, from the person who built this

I can’t read markdown.
There, I said it.

I’m a visual person. I love AI (mostly), and every day it hands me a mountain of documents I need to read and decide on, fast. But when that mountain is a wall of asterisks and pound signs, my brain just… slides right off it.

Read the rest of the letterShow less

Raw markdown looks like code soup to me. I need to see the headings. I need the table to be a table. And for a long time I was too embarrassed to admit that, because everyone around me seemed fine.

Then I lost a client presentation. Four minutes hunting for the file, pasting it into a Google Doc, then fixing the formatting by hand, while they watched. That was the day I stopped pretending and built the thing I needed.

It started as a simple markdown reader. It didn’t stay one. I wanted to edit, not just read. I wanted to move between .md, .txt, .docx and PDF without thinking about it. I wanted to open a whole folder, type half a filename and land on the right doc, then breeze through a 300-page file without losing my place.

I wanted One Clear Reader. I hope you enjoy using it as much as I’ve enjoyed making it.

Tell us what you love and what drives you mad. We read every note, and we’re building this to be exceptional.

Frequently asked questions

(the ones we all ask!)
How do I open a .md file on a Mac so it's readable?

Open the .md file in One Clear Reader and it shows as a formatted page: real headings, tables that line up, and no # or ** symbols. Double-click it, drag it onto the app, or paste its path. The file stays a .md file on your Mac.

To make every .md file open this way, click Make this my default .md reader on the welcome screen.

What files does One Clear Reader open?

One Clear Reader opens Markdown (.md), plain text (.txt), Word (.docx), PDF, EPUB, web pages (.html) and spreadsheets (.csv and .tsv). Markdown and text files can be edited. Pro can also edit the words in Word files.

Is One Clear Reader good for ADHD or dyslexia?

One Clear Reader has free reading profiles made for this: Neuro-friendly uses the Atkinson Hyperlegible font with extra letter, word and line spacing and a soft cream page. Paragraph Focus shows one paragraph at a time. Large Print makes everything bigger. Pro adds a Custom profile with your own font and spacing.

Does One Clear Reader upload my documents?

No. One Clear Reader reads, converts and saves your files on your Mac. It has no account and never uploads document contents. It only goes online to check a licence key and to check once a day for updates, which you can turn off.

Is One Clear Reader free?

Yes, there is a free version with no time limit: reading, search, paste a path, Latest from your AI and Markdown editing. Every Pro feature is free for 30 days, no card needed.

Pro is $19.99 a year, or $59 once for lifetime. At launch, lifetime is $29 for the first 500 buyers. One personal licence covers 3 of your Apple devices, like your laptop and your desktop. It all runs on your own devices, so your files stay yours. Mac today; iPhone and iPad are coming soon.

Which Macs does One Clear Reader run on?

One Clear Reader needs macOS 13 or later on a Mac with Apple silicon (M1 or newer).
