Ask your notebook

Chat with your notes

  • Grounded in your real notes, with citations
  • Searches across every folder for you
  • Can even draft and edit notes on request

Summaries & organizing

Drowning in a long note or a rambling meeting transcript? Ask for a summary, a bullet list of action items, or a cleaner structure. SemantiNote turns your raw thoughts into something you'd actually re-read.

  • One-click summaries of any note
  • Pull out action items and decisions
  • Reorganize messy notes into a clean outline
  • Turn any note or spreadsheet into a polished PDF — tables included

Voice transcription

Some thoughts are faster spoken than typed. Hit dictate and just talk — SemantiNote writes it down for you, live, and completely offline. No transcription service, no upload.

  • Live dictation straight into your note
  • Runs on-device — your voice never leaves

Never miss a detail

Meeting capture

Record your Teams, Zoom, Slack or Discord meetings directly into a note. SemantiNote mixes your microphone with your computer's audio, so it hears both you and everyone else on the call — then you can ask the AI what happened.

  • Captures both sides of the conversation
  • Live transcript you can watch fill in
  • Summarize & extract action items afterward

Encrypted secret safe

A built-in vault for the things you shouldn't paste into a plain note — logins, API keys, license codes. Save a name, username and password together; everything's encrypted on your machine with your operating system's secure keychain, and revealed only when you ask. Free for everyone.

  • Encrypted with the OS keychain (macOS & Windows)
  • Name, username & password — reveal or copy each in one click
  • Optional PIN lock on top of the encryption
  • Kept out of your notes — never indexed or sent to AI

Sign & fill in PDFs

Someone sends you a contract or a form? Open it in SemantiNote, add your signature, type the date or any text, fill in the form's boxes — and save. No printing, scanning, or extra app.

  • Draw your signature, or type it in a script, handwritten or classic style
  • Add text anywhere — pick the size, color or a highlight
  • Fill in a PDF's own form fields, checkboxes and dropdowns
  • Save a copy or save over the original — opens anywhere

Calendar & reminders

A simple calendar built right in. Add a reminder for an appointment, a bill or a birthday — it pops up with the sound you pick, even when SemantiNote is minimized. Missed one while the app was closed? You'll see it next time you open it.

  • One-time or repeating reminders (every weekday, every Monday…)
  • Snooze for 10 minutes, an hour, or until tomorrow
  • Month, year and "next 7 days" views
  • Choose a sound: chime, bell, alarm, gentle or silent

A real notebook, not a toy

Rich notes & tables

Formatting, highlights, colors, images you can resize, and tables — write real documents, not just plain text.

Any file type

Notes, code, JSON, markdown, plain text — create a file, name it anything, and get the right editor automatically.

Multiple tabs

Open several notes at once in browser-style tabs and flip between them as you work.

Pins & colors

Pin the notes you use most and color-code your folders so your notebook stays organized at a glance.

Password-protect a note

Lock any single note with a password — it's encrypted on disk and only you can open it.

Recent & last edited

Jump straight back to what you just opened or changed — every note shows its date.

Works with Excel

Open and edit CSV spreadsheets in a familiar grid — accents, € signs and Excel's formats are kept exactly, so they open right back in Excel.

Keyboard shortcuts

Browser-style shortcuts on Mac and Windows — switch tabs with Ctrl+Tab, jump with ⌘1–9, reopen a closed tab with ⌘⇧T.

Light on your computer

Nothing runs when SemantiNote is closed, the AI frees its memory when idle, and you pick how much memory it can use.

Free to download. Private from the first keystroke.
