Before you install

iPhone and iPad. Install the free TestFlight app from the App Store, then open the invitation link in the release below. Updates arrive through TestFlight.
Mac. macOS 26 or later, Apple silicon or Intel. Open the DMG and drag E1pi to Applications. On first launch macOS asks for microphone and folder access; those prompts belong to the pipe-shell feature. The first time the AI controls your Mac it also asks for Screen Recording and Accessibility.
Windows. Windows 10 (build 19041) or later, 64-bit. The installer is not yet code-signed, so SmartScreen shows "Windows protected your PC": choose More info, then Run anyway.

Build 87

The start-up screen names the build. While the app loads and syncs your data, the full build name now appears under the logo, for example E1pi for Mac 1.0 (87) or E1pi for iPhone 1.0 (87), so you can tell at every start which build you are running.

Grok Voice is removed. Grok Voice, the voice-to-voice conversation feature, is no longer part of E1pi, so it has been taken out of the Mac, iPhone and iPad apps. Voice mode is unchanged: your speech is still turned into text and replies are still read aloud, with Grok or your device's own speech engines, as chosen in the voice settings.

Voice mode can use your Mac's own speech engines. Until now Voice mode always sent your speech to Grok to be turned into text, and Grok read the answers back. The Mac app can now do both on the Mac itself. Open the voice settings (the speed chip on the voice pill) and choose Grok or Mac for Speech to text and for Reply voice — each on its own, so you can mix the two and compare. Grok stays the default and nothing is removed. iPhone and iPad have the same choice since build 83.

The app opens the page your company is assigned to. Instead of a fixed address, every app now asks the E1pi server where your company's workspace lives the moment you sign in, and opens that page. Moving a company to another E1pi server is a one-line change on the server — no app update, nothing to reinstall. Same change on iPhone, iPad, Mac and Windows.

The Mac app asks for its own permissions. When the AI controls your Mac for the first time, the app now brings up the standard macOS dialogs for Screen Recording and Accessibility, each with an Open System Settings button, instead of leaving you to find the switches yourself. If Screen Recording is still off, the AI is told exactly which setting to turn on rather than failing silently. In the chat, every screenshot the AI takes now appears in one live screen panel that updates as it works, with the cursor marked, and screenshots are no longer kept on the server.

Sign-in no longer loops. On a flaky connection the iPhone app could ask you to confirm or sign in again and again and finally stop at "Native sign-in failed" with Microsoft error AADSTS50196. Every reconnect of the live data socket made the app ask Microsoft for new tokens, and after a burst of such requests Microsoft blocks the app for a few minutes. The app now keeps its tokens for their lifetime, asks Microsoft only when they are about to expire, and never opens the sign-in sheet because of a temporary network or Microsoft error.

Two side windows now stack. Add 2 windows on side used to open two full-size pages next to the main one, tripling the window width. They now share a single column as wide as the main page, one above the other at half height each, so the window grows by one page instead of two. Hover a stacked page and it smoothly grows to 80 percent of the column while the other shrinks to 20 percent; move to the other page and they swap. The layout stays where you left it when the mouse returns to the main page.

The Transporter truck now lives in the page header. Build 71 drew it as a native button over the top-right corner, exactly where the page shows the date and the instance chip, so it looked lost as soon as the page painted. It is now part of the header itself, left of the date, with its own space — same tap, same Transporter Mode.

Transporter Mode for road transporters in India. A truck icon at the top-right opens the transporter's own screens: the jobs assigned to them, every document for the trip, pickup and delivery addresses with navigation, the e-Way Bill and its validity. The driver accepts the job with the vehicle number, starts the trip, photographs the loading, and at delivery takes photos while the receiver and the driver sign on the phone. Starting a trip asks for Always location so the phone can report route checkpoints about every 30 minutes of driving — overnight and with the phone locked — which gives the office an ETA without live tracking.

Grok Voice works on the Mac. On macOS 26 the Mac app's audio engine refused to start the moment echo cancellation was switched on (CoreAudio error -10875), so the Grok panel showed Connecting… and closed. The app now creates its audio output path before enabling voice processing, and Grok Voice starts with echo cancellation on — speakers or headphones. The web page changed too: when Grok Voice cannot start, the panel shows the reason for a few seconds instead of just closing, on every platform.

The iOS ✓ is back, and the row sits right above it. The standard iOS 26 bar above the keyboard (↑ ↓ ✓) shows again, so ✓ closes the keyboard as on any web page. Instead of guessing the bar's size, the app now tells the page exactly where the bar's top edge is each time the keyboard opens, and the page places the icon bar and the model chip 7 px above that edge — the same small margin they have always kept above the keys. No bar covering them (Build 59), no empty strip (Builds 66 and 67).

Back to the keyboard layout of Build 60. The iOS 26 bar above the keyboard is hidden again inside E1pi, so the icon bar and the model chip sit directly above the keys — no bar covering them (Build 59), no empty strip above the bar (Builds 66 and 67). The bar had only been brought back for the developer key row, which is gone; nothing else depended on it. Close the keyboard by sending the message or tapping outside the input, as before.

The gap above the keyboard bar is closed. iOS 26 keeps a tall, mostly transparent band above the keyboard for its floating ↑ ↓ ✓ bar — in Safari that band also holds the address pill. Build 66 measured the whole band, so the icon bar and the model chip were lifted far above the bar with an empty strip between them. The app now measures the visible bar itself, so the row sits just above the ↑ ↓ ✓ pill, and it remembers the measurement so the very first lift is right as well.

8 October 2026 Released by Vinit D Gandhi iPhone and iPad 1.0 (66) on TestFlight · Mac 1.0 (64) · Windows 1.0.17

The iOS keyboard bar is back, and nothing hides behind it. Build 60 switched off the system bar above the keyboard because, on iOS 26, its floating ↑ ↓ ✓ pill landed on top of the icon bar and the model chip. That also took away the tick that puts the keyboard down, and the replacements since — a developer key row, a tick drawn by the page — added things nobody needed. This build lets iOS do its job again: the standard bar is back with its ✓ to close the keyboard, and the app now tells the page how tall that bar is, so the icon bar and the model chip rise above it instead of sitting under it. The developer keys row and its @devkeys entry are gone.

Work on the website and talk to the AI at the same time. On the Mac the web drawer (@teams, @website, @outlook) no longer covers the whole window: it opens as a top pane above the E1pi page, exactly as on the iPhone, with the browser bar on top and a grabber to drag the split between a quarter and 85 % of the window. The page below keeps its message input, so you can read Teams or the public website while you ask the AI for changes. And on every platform, when the drawer shows the E1pi website, you can select any text or image on it and tap the model chip: the selection is pasted into your message together with the file path (www/websitev4.html) and where on the page it sits, so the AI knows exactly which part to change, no screenshot needed. A second tap sends as usual.

Scan a UPI or PayNow QR code and pay it from the company Wise balance. A rupee icon in the bottom bar (iPhone and iPad only) opens a scan-to-pay sheet styled like the activity sheet: the rear camera reads the merchant's code, and the app works out on its own whether it is an Indian UPI code or a Singapore PayNow code. You see the payee, the UPI ID or PayNow mobile / UEN, the amount (locked when the QR fixes it, otherwise you type it), a purpose for Indian payments and a reference. Confirm with Face ID, the same passkey check used for approvals, and the payment goes through the Wise API as a transfer from the SGD balance to the payee's UPI ID or PayNow proxy. The receipt shows what was paid, what was debited including the Wise fee, the exchange rate and the Wise transfer number, and every payment is recorded in the activity feed with the name of the person who signed it. It is a Wise transfer into the merchant's UPI- or PayNow-linked bank account, not an instant UPI checkout, so the merchant sees a bank credit rather than a UPI app notification.

A developer key row above the keyboard, on request. Typing code or terminal commands on an iPhone means hunting through the 123 and #+= layers for brackets, pipes and backticks. Type @devkeys in the input to switch on a single row of keys above the keyboard: scroll it sideways, tap a key and it goes in at the cursor. Tab, paste, the four arrows, brackets and braces, quotes and backtick, slashes, pipe, tilde, the operator symbols and combos such as =>, &&, ===, ../ and ~/. It is laid out like the Termius terminal app's key bar: plain white keys on the page background, with a button at the right that hides the keyboard. Select @devkeys again to switch it off; the choice is remembered. It takes the place of the system bar that Build 60 removed, so nothing covers the icon bar or the model chip.

The keyboard no longer hides the model chip and the icon bar on iOS 26. iOS 26 draws its own small bar above the keyboard — up and down arrows and a checkmark — as a floating pill. That pill sits outside the keyboard area a web page can measure, so it landed exactly on top of E1pi's bottom bar: the icons and the model chip were covered while you typed. The app now switches that system bar off. The page's own close button already does what the checkmark did, and the icon bar and model chip stay in view with the keyboard open.

Side windows are easier to tell apart. With two or three identical E1pi pages next to each other, nothing said which was which. Every page now shows its name in the thin strip along its top: Window 1 on the main page while side windows are open, Window 2 and Window 3 on the side pages. A side page closes with a round button at its top-left, where the main page has its traffic lights. The divider between pages is a visible hairline with a handle that lights up when you point at it, and the e1pi and tunnel icons stay at the main page's top-right instead of drifting to the far corner over the last pane. Mac users on build 19 or later receive this through the in-app update banner.

Side windows: the grabber now follows your pointer. In build 57, dragging the vertical grabber between side pages lagged well behind the mouse, because every pixel of movement re-laid out two complete E1pi pages. The grabber now moves with the pointer on every event as a thin divider, the pages behind it re-flow at a steady 30 frames per second and settle exactly where you let go, and the resize cursor stays for the whole drag. Everything else from build 57 is unchanged. Mac users on build 19 or later receive this through the in-app update banner.

Side windows — several E1pi conversations side by side in one Mac window. Type @side1 or @side2 in the chat box and the app lays out one or two more E1pi pages to the right of the one you are in. Each is a complete E1pi with its own conversation, so you can ask the AI several things at once without switching windows. The window widens to fit (when the screen is too narrow every page gets an equal share), the vertical grabber between pages drags left and right to resize them, the × at the top-left of a side page closes it, and @sideclose closes them all. Up to three side pages. Mac users on build 19 or later receive this through the in-app update banner.

Grok Voice keeps talking when your iPhone screen is locked. Until now the Grok conversation lived inside the web page, and iOS pauses web pages the moment the screen locks, so listening stopped and the connection dropped. From this build the microphone, the playback and the connection to Grok run natively in the app, the same way dictation already does, so you can lock the phone, put it in your pocket and carry on the conversation. The Mac app gets the same native audio path.

E1pi one keystroke away, from anywhere on the Mac. Press Option + Space while you are in Safari, Mail, Excel or any other app and E1pi comes to the front with a fresh window cascaded over the last one — no need to click E1pi first. A small E1pi icon now sits in the menu bar: click it for New Window, and for a checkbox that decides whether Option + Space belongs to E1pi everywhere or only while E1pi is the front app. Untick it and other apps get the key back, for example to type a non-breaking space. The choice is remembered. Mac users on build 19 or later receive this through the in-app update banner.

Build 25

14 September 2026 Released by Vinit D Gandhi Mac 1.0 (25) · Windows 1.0.17 · iPhone and iPad 1.0 (24) on TestFlight

More than one E1pi at a time, without losing any of them. Press Option + Space on the Mac or Alt + Space on Windows and a second E1pi window opens at exactly the size of the one you are in, a little down and to the right of it, the way Finder and Explorer stack their windows. Keep pressing and the windows fan out across the screen; when the next one would fall off the edge it starts again from the top-left corner. Each window is its own chat, so you can run a report in one while you type in another. Mac users on build 19 or later and Windows users on 1.0.16 receive this through the in-app update banner.

Build 20

12 September 2026 Released by Vinit D Gandhi Mac and iPhone/iPad 1.0 (20) · Windows 1.0.16

Voice commands, done properly. Tap the microphone and just say what you want — "show me profit and loss for SG for the last six months", "open my sessions", "switch to light mode", "read the last answer". Apple's on-device model hears you and acts inside the app itself; it hands data questions to the E1pi AI and reads the answer back. Nothing you say is typed into the input box any more. Mac users on build 19 receive this build through the new in-app update banner.

Build 19

12 September 2026 Released by Vinit D Gandhi Mac 1.0 (19) · Windows 1.0.16 · iPhone and iPad 1.0 (18) on TestFlight

The Mac and Windows apps now update themselves. When a new build is published, a banner appears inside the app: Update now downloads it, installs it and restarts the app; Later hides the banner for a day. No update framework is involved: the app reads release announcements from the same activity feed it already keeps in sync. This is the last build you install by hand.

12 September 2026 Released by Vinit D Gandhi Mac 1.0 (18) · iPhone and iPad stay on 1.0 (17) · Windows 1.0.13

Mac-only release. Voice mode arrives: talk to E1pi hands-free. Your words are understood on the Mac itself by Apple's on-device model, the request runs, and the answer is read back to you. The Mac window is now portrait-only.

Build 17

9 September 2026 Released by Vinit D Gandhi iOS and Mac 1.0 (17) · Windows 1.0.13

The app now opens ai.e1pi.com. The public website moved to e1pi.com on Azure Front Door and old app links redirect, so earlier builds keep working, but this build talks to the app host directly.
