AI Note Taker, No Meeting Bot — Free on Android & Mac

Search “AI note taker” right now and you’ll meet the same cast of characters everyone’s ranking in 2026: Otter, Fireflies, tl;dv — apps that send a bot to join your video meetings and take notes for you. There’s even a wave of hardware note-takers that clip to your shirt or sit on the table and record everything.

They’re genuinely useful. But the popular ones share the same architecture: a bot (or a gadget) has to be present at the conversation. If there’s no calendar invite, no bot joins. If you’re on a phone call with your landlord, the bot isn’t there. If you’re sitting in a lecture hall, the bot isn’t there. If the notes you need are sitting on your screen — a webinar, a patient handout, a 60-message WhatsApp thread from your team — no bot can see that either.

I run analytics for Arc, an AI assistant that lives on Android and macOS, and the last 30 days of usage data made the gap obvious to me. Arc just crossed its highest daily-active-user numbers ever — daily actives nearly doubled across September, from 234 to 448 — and one of the features pulling people in is the least “meeting” thing you can imagine: point Arc at a recording you already have, or at anything on your screen, and it writes the note for you. No bot joins anything. No invite. No minutes meter.

Here’s how a note taker without a meeting bot actually works on Android and Mac — and which conversations it can cover that bots can’t reach.

Why the meeting-bot model leaves gaps

Before getting to Arc, it’s worth being precise about what the popular AI note takers actually require — because none of it is a dealbreaker for board meetings, but all of it matters for real life:

• They need a meeting platform to invade. Otter, Fireflies, and tl;dv bots join scheduled video meetings on Meet, Zoom, or Teams. A phone call on your SIM, a voice memo from an interview, a recording of an in-person conversation — none of that reaches them.
• Everyone sees the bot. “Otter.ai is recording this meeting” appears in the participant list. In client calls and interviews, that announcement itself changes the conversation — people ask about it, sometimes object to it.
• Free tiers meter minutes. The free plans of the big bot apps typically cap how many minutes you can transcribe each month. Fair enough — running bots costs money — but “free” can run dry partway through a busy month.
• They only know what the call said. A bot transcribes the meeting — usually only the meeting. It can’t read the brief that was on your screen during the call, or turn what was said into study material you can review on the commute.

Arc attacks this from the opposite direction: instead of sending a bot to capture conversations, it takes the recordings and text you already have and turns them into structured notes. That’s the core of the design — Arc starts from what you already have, which is how it manages to be brand-agnostic, and how it reaches conversations in apps the bot tools weren’t built for.

The Android side: Call Insights turns recordings into notes

Arc’s Call Insights is the engine for that. It doesn’t record calls for you — your phone’s own call recorder or any recording app does that — and that’s precisely the point: it consumes recordings you already possess. Here’s the flow.

Upload a recording, get the full note

1. Open Arc and go to Call Insights (from Settings, or its dedicated tab).
2. Tap Upload Recording. The Android file picker opens — Arc handles MP3, M4A, WAV, AAC, OGG, and FLAC files up to 100 MB.
3. Pick the file. Arc shows the filename, the size, and an estimated processing time before you commit.
4. Tap Analyze Recording. Processing runs at roughly one to two minutes per ten minutes of audio — a 40-minute call is a five-minute wait.
5. The finished note opens automatically and lands in your list as an unread item, with a high-priority notification if you enabling new-insight alerts.

What you get: the four-section note

This is the part that separates an AI note taker from a bare transcription app. The report Arc builds has four sections:

• Transcript — the full conversation with bold speaker labels (“Speaker 1:”, “Speaker 2:”) and gray timestamps at intervals, like [02:15]. Long transcripts scroll smoothly; you can copy the whole thing in one tap.
• Summary — a two-to-four-sentence overview. After a 40-minute supplier call, this is the paragraph you actually read first: what the call was about, what got decided, what happens next.
• Action items — a bulleted checklist the AI extracts from the talk: “Send revised proposal by Friday,” “Confirm delivery slot for Tuesday.” Each item is checkable, so the report doubles as your follow-up task list.
• Key insights — the decisions and facts that were spoken but never written down: budget approved, the deductible you agreed to, the appointment moved to the 20th.

Everything above lives on your device. Arc references the original audio file rather than storing it, the transcript and analysis are saved locally in the app, and Google Drive backup stays optional and off unless you turn it on.

Auto Analysis: set it up once

Manual upload is great for one-off calls. But the feature people tend to stick with is Auto Analysis:

1. In Call Insights, switch the toggle from Manual Upload to Auto Analysis.
2. Tap Add Folder — Android’s document picker grants Arc scoped access to only that folder (your recorder app’s output folder, or your phone’s default /Recordings/Calls/ directory). Arc never gets broad storage access.
3. In Auto Analysis settings, choose how often Arc checks the folder — the dropdown gives you 6-hour, 12-hour, or 24-hour intervals — and set an optional cutoff date so older recordings get skipped.
4. Done. From then on, Arc checks the folder on the schedule you picked (its background worker respects Android’s battery optimization), and when it finds a new recording, it processes it and posts a high-priority notification with a deep link straight into the fresh note.

I set mine to watch my recorder’s folder every 12 hours. Recruiter screening calls, the dentist’s office, that contractor quote — each one becomes a speaker-labeled transcript with action items before I’ve opened my laptop for the day. If the network flakes mid-processing, Arc retries with exponential backoff (up to three attempts) instead of silently losing the note.

And the privacy detail I keep coming back to: the audio goes to Google’s AI for processing and is not stored on Arc’s servers, transcripts stay on-device, and Arc can’t read a single file outside the folders you granted. You can search your past insights, mark them read or unread, and clear your insight history with a single confirmation dialog whenever you want a clean slate.

The Mac side: take notes from anything on your screen

Calls are half the story, and Call Insights is Android-side — call recordings live on phones. What about the notes you need from stuff that isn’t audio at all? That’s where macOS comes in, and it’s one of Arc’s two live platforms.

On Mac, press ⌃ Space (the default hotkey, rebindable in Settings) and Arc’s menu appears as a dark, non-activating panel over whatever app you’re using — the same Spotlight-style behavior you’d expect from your OS, except the menu is full of AI actions:

• AI Summary — Arc reads the text of the frontmost window on demand and returns numbered key points in a floating result panel, with the source app shown on a chip. A 30-page RFP PDF, a webinar you paused, a documentation page — summarized into a scannable list in seconds. Save, Share, or Copy from the same panel.
• Save Content — one tap parks the full on-screen text into your searchable library, with the source attached. That’s your raw note, no retyping.
• Chat Screen — ask questions about what’s on screen (“what are the risks listed here?”) and chat with the page as context.

Because the panel is non-activating and everything is keyboard-driven (arrow keys to move, Return to run, Esc to dismiss), taking the note never interrupts the thing you were doing. The workflow is: see something you need to remember → ⌃ Space → Save or Summarize → back to work.

Arc is live on Android and macOS today. Windows and iOS versions are in development — all four platforms are the goal, and the note-taking workflow (screen capture → summary → saved note) is the same product logic on each.

Notes that go somewhere: search, flashcards, and listening back

A note you can’t find later is just a transcript-shaped memory leak. Arc’s notes feed into the parts of the app that make them actionable:

• A searchable home. Every summary and saved screen sits in a library grouped by Today / Yesterday / Last Week, with category badges (Article, Email, Social…), source app icons, and unread indicators. The search bar runs the full text, and Call Insights search runs through transcripts — search “deposit” and find the phone call where it was mentioned.
• Flashcards from study notes. For lectures, Arc can turn the note into question/hint/answer flashcard decks — flip with a tap, track how many you’ve reviewed. I’ve watched students make this their entire revision loop: record class → auto-note → deck → test yourself.
• Listen instead of re-read. AI Read plays any note back as audio. Reviewing last week’s action items on the commute costs nothing; the reading never has to happen again.
• An Unread Queue. New notes and insights arrive as unread items, so “I’ll process that call later” becomes a queue instead of a folder of guilt.

The numbers say the no-bot gap is real

Some fresh usage data from the last 30 days (through October 3), since I think products should show their work:

• Daily active users nearly doubled during September: 234 on Sep 11 → 448 on Sep 22, holding around 420/day into October (424 on Oct 3).
• Arc generated 187,163 feature impressions and counted 24,137 sidebar opens in 30 days — the floating sidebar is how most people summon Arc on Android.
• 17,981 core-value actions were used in the month — summaries, extracts, notes, and chats doing real jobs daily.
• 6,243 explicit feature uses and 5,708 action taps — deliberate taps on AI actions, not drive-by opens.

Two-thirds of the “AI note taker” market is currently fighting over bot slots in calendar meetings. The other two-thirds of conversations — phone calls, voice memos, lectures, everything on a screen — is where Arc plays, and the growth curve suggests people were waiting for exactly that.

How Arc compares to the familiar options

• Otter / Fireflies / tl;dv: excellent inside the video-meeting box they were built for, but a bot must join the call, free tiers meter minutes, and phone calls, lectures, and screen content are out of scope. Arc asks for no seat at the table — the recording already exists.
• Hardware note-takers (the clip-on recorder gadgets): a couple hundred dollars for transcription-plus-summary of conversations. Arc does the same job with the recordings any Android phone already produces, for free.
• Recorder apps with built-in AI (Samsung, Pixel): tied to specific hardware and usually transcription-only. Arc works across any recorder’s files and adds summary, action items, key insights, search, flashcards, and playback.
• Notes apps: wonderful places to store notes — but you still write them. Arc writes them, then hands off.
• Copy-pasting into ChatGPT or Claude: works in a pinch, but you’re shuttling text by hand, every time, with no library or follow-up structure. Arc captures in place and routes results into surfaces you can search, study, and act on.

Getting started in two minutes

1. Install Arc on your Android phone — it’s free on Google Play.
2. Open Call Insights and upload any recording you already have — your last meeting recorded on your phone counts.
3. Flip on Auto Analysis and grant Arc access to your recordings folder so future calls become notes automatically.
4. Want the same notes-from-anything on your desktop? Arc for Mac is live — grab it from www.appsrethink.com and press ⌃ Space in any app. (Windows and iOS are coming soon.)

FAQ

What is an AI note taker without a meeting bot?

It’s a note taker that works on recordings and text you already have instead of sending a bot to join live meetings. Arc analyzes phone-call recordings, voice memos, and anything on your screen — producing a transcript, summary, action items, and key insights — without joining any meeting platform and without announcing itself to participants.

Does Arc’s AI note-taking work on any Android phone?

Yes. Call Insights is brand-agnostic — it processes standard audio files (MP3, M4A, WAV, AAC, OGG, FLAC) from any call recording app or voice recorder, on Android 10 and above. Your phone brand doesn’t matter, and neither does your recorder app.

Is Arc’s AI note taker free?

Yes. Call transcription, summaries, action-items extraction, on-screen AI summaries, and the saved-content library are included at no cost. Arc offers an optional premium tier for advanced features, but the core note-taking workflow is free — no monthly minute meter on the core features.

Where are my transcripts and notes stored?

On your device. Arc references your original audio files rather than storing copies, transcripts and generated notes are saved locally in the app, and audio is processed for analysis rather than kept on Arc’s servers. Optional encrypted Google Drive backup is available if you want cloud copies — it’s off unless you enable it.

Can I use Arc as an AI note taker on Mac?

Yes — Arc is live on macOS today. Press ⌃ Space over any app to summon the Arc menu, then use AI Summary for numbered key points of what’s on screen, Save Content to store the full text, or Chat Screen to ask about it. The same note-taking workflow extends your saved library from desktop to phone. Windows and iOS are in development.
