Everything you need, nothing sent away

A full notebook, a private AI, voice and meeting capture, and a vault for your secrets — working together on your device, offline.

Ask your notebook

Chat with your notes

Ask a question in plain English and get an answer built from your own notes — with the exact notes it drew from cited right in the reply. It's like having a second brain that has read everything you ever wrote.

  • 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

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 — API keys, passwords, license codes. Everything's encrypted on your machine using your operating system's secure keychain, searchable by name, and revealed only when you ask.

  • Encrypted with the OS keychain (macOS & Windows)
  • Search by name, reveal or copy in one click
  • Kept out of your notes — never indexed or sent to AI

Recent, last accessed & last edited

Your most recent work is always one click away. Switch between "last accessed" and "last edited," each with its date, so you can get right back to whatever you were just working on.

  • Last accessed — what you opened recently
  • Last edited — what you changed most recently
  • Dates on everything so nothing gets lost

A real notebook, not a toy

Rich notes & tables

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.

A native desktop app on both platforms, with the exact same private, offline experience.
