ON-DEVICE LOCAL AI OR CLOUD BY CHOICE · YOU CONTROL THE ROUTE

Gestu v2.1 · The ChatGPT & Gemini alternative

ChatGPT and Gemini answer.
Gestu acts.
On your phone.

Ask ChatGPT or Gemini a question and you get an answer. Ask Gestu and it answers, then does the work: reads your inbox, runs your calendar, drives your apps, and opens a Debian Linux workshop with coding agents — on your phone. One flat yearly price for Gestu Pro, not another ~US$20/month chat subscription. No account required.

Where does my data go? On-device local models (Gemma / LiteRT): your prompts stay on your phone; turn on Total Privacy Mode and all cloud connections are blocked (0 bytes sent to cloud AI). Gestu Pro (managed AI): requests you send to DeepSeek V4.1 Flash are processed by DeepSeek via pro.gestu.ca. Bring Your Own Key (BYOK): requests go directly from your phone to the provider you configured and follow that provider's retention and training policies. Licence activation and periodic refresh connect to entitlements.gestu.ca, and payments/emails are handled by Stripe (Link) and Resend.

02 — What it does for you

Three very different days.
One assistant for all of them.

Pick the life closest to yours and watch a real day with Gestu. Everything below is live — go on, touch it.

01 · Your local file cabinet

Keep sensitive client documents on your phone with Total Privacy Mode.

Drop in a client NDA, a rate card, or a 40-page statement of work. When you run an on-device model with Total Privacy Mode enabled, Gestu reads and answers questions locally on your handset — blocking cloud connections completely. When you switch Total Privacy off to use cloud AI, Gestu Pro sends requests to DeepSeek, or your BYOK key connects directly to your chosen provider.

  • App-private local storage — conversations and local memories stay in your app's private storage directory
  • API keys sealed in hardware — provider keys are encrypted via Android Keystore (AES256_GCM)
  • Total Privacy Mode — flip it on to block all cloud traffic and run strictly on-device

Total Privacy Mode is ON. Cloud connections are blocked — only on-device local models run, and 0 bytes are sent to cloud providers.

03 — Why Gestu

Two kinds of assistant.
Only one works for you.

One locks you into a single cloud and profiles your habits. Gestu gives you on-device local models, 30+ BYOK providers, or Gestu Pro processed by DeepSeek.

The usual suspects

Mandatory accounts, single-cloud lock-in, and opaque data rules.

  • Mandatory sign-in & profilingEvery conversation tied to a permanent cloud account and behavioural profile.
  • One vendor's cloud or nothingYou cannot bring your own API keys or switch to a local on-device model.
  • Chat-only sandboxCan draft snippets in a browser box, but cannot run a real Linux environment on your phone.
  • Support is a bot mazeA loop of help articles and automated replies when billing or setup goes wrong.
  • Useless without internetNo connection, no assistant. Your phone is just a thin client for their servers.

The verdict: tied to an account, locked to one cloud.

The Gestu way

You choose where every prompt runs.

  • Local storage & hardware KeystoreConversations live in app-private storage on your device; API keys are encrypted with Android Keystore (AES256_GCM).
  • Gestu Pro: US$99/yr Founders (US$149/yr standard)Zero-setup managed DeepSeek V4.1 Flash processed by DeepSeek, on one device, with a 14-day money-back guarantee.
  • Gestu Build Linux workshop built inA proot Debian or Alpine sandbox with coding agents running directly on your phone.
  • A human on the other endEmail support@gestu.ca — replies within 2 business days (24-hour priority response for Business licences).
  • On-device, BYOK, or Pro cloudRun local Gemma/LiteRT models offline with Total Privacy Mode, use your own key across 30+ providers, or use Gestu Pro.

The verdict: no user account required · transparent routing.

04 — How it works

Three layers.
Complete control.

Scroll down — each layer, explained in plain English.

Layer 01 · On-device local inference

Run Gemma & LiteRT models directly on your phone.

Download an on-device model and run inference on your phone's own processor. When you use a local model with Total Privacy Mode enabled, all cloud traffic is blocked and 0 bytes of your prompts leave the device — even in airplane mode.

TOTAL PRIVACY MODE0 bytes sent to cloud AI
COSTIncluded in Free & Gestu Pro

Layer 02 · Gestu Pro & 30+ BYOK Providers

Managed DeepSeek V4.1 Flash — or 30+ providers with your own key.

Don't want to manage API keys or top up balances? Gestu Pro gives you zero-setup access to DeepSeek V4.1 Flash processed by DeepSeek. Prefer to bring your own key? Both Free and Pro support 30+ AI providers with your own API key (Anthropic, OpenAI, Gemini, DeepSeek, Groq, Mistral, OpenRouter, and more).

GESTU PRO CLOUDProcessed by DeepSeek
MANAGED MODELDeepSeek V4.1 Flash
BYOK SUPPORT30+ AI providers with your own key
SEAT LIMITOne device per Pro licence

Plainly When you use Gestu Pro, your prompts are sent through pro.gestu.ca and processed by DeepSeek. When you use your own API key (BYOK), your prompts go directly from your phone to that provider and are governed by their privacy and training policies. Either way, your files, sandbox work, conversations and memories stay on your phone — a cloud model only ever sees what you put in the message: the text you send, or a file you choose to attach. Want no cloud traffic at all? Turn on Total Privacy Mode to restrict Gestu strictly to on-device local models.

CLOUD ROUTING · 30+ BYOK SUPPORTED · PRO MANAGED AI

Layer 03 · Gestu Build Linux Sandbox

A real Linux environment, isolated inside your phone.

With Gestu Pro, the assistant gets Gestu Build — a proot Debian or Alpine Linux sandbox inside app storage where coding agents can write, test, and run real software right on your handset.

Apps you can install

Finished apps come straight out of the workshop, ready to install.

06 — Straight answers

The questions you're about to ask.
Answered.

Why Gestu instead of ChatGPT or Gemini?

ChatGPT and Gemini are excellent at answering. Gestu is built to act: it reads your inbox, runs your calendar, stages messages, drives other apps, and opens a Debian Linux terminal with coding agents on the phone you already carry. It is one flat yearly price — US$99 Founders, then US$149 — not a ~US$20/month chat subscription.

Where does my data go? Does Gestu Pro send it to DeepSeek?

On-device models never leave your phone, and BYOK requests go straight from your phone to the provider you chose — Gestu's servers are not in that path. Managed Gestu Pro requests go through pro.gestu.ca to DeepSeek, which processes them under Gestu's account: you need no DeepSeek account or key, and no country of processing is promised. Total Privacy Mode blocks all cloud routing.

What happens if I cancel, or hit the monthly allowance?

Nothing on your phone is deleted or locked. Chats, memories, projects and any installed Linux environment stay. At the fair-use ceiling a dialog keeps you working with your own key or an on-device model until the meter resets on the 1st. Cancel anytime; access runs to the end of the paid year.

How many devices can I use?

One device per licence. A seat can be released in the app. If a new phone claims it after the old device has been idle for 14 days, it replaces it; otherwise release the old device first.

Why is the app not on Google Play?

The FOSS build ships SMS, notification and accessibility tools that Play restricts. Releases are signed, and every build publishes its SHA-256 checksum so you can verify exactly what you install. The Play build, when it ships, omits those permissions.

Do I need an account?

No. Checkout emails you an activation code; paste it into Settings → Gestu Pro. The licence binds to your device, and there is no Gestu account or password to manage.

07 — One subscription, not another chat app

The assistant that acts.
One flat yearly price.

ChatGPT Plus and Gemini Advanced are roughly US$20 a month for chat. Gestu Pro is US$99 a year (Founders price for the first 500) for an assistant that runs your phone, plus the Gestu Build Linux workshop and zero-setup managed DeepSeek V4.1 Flash.

ChatGPT Plus / Gemini Advanced

~US$20/month · chat-first

~US$20/ month

Excellent chat apps. They answer questions; they don't run your phone.

  • Chat, search, images, and voice
  • Your conversations are processed in their cloud
  • No phone-wide tool control — inbox, calendar, SMS, apps
  • No Debian Linux workshop or coding agents
  • Billed monthly, indefinitely

Plainly Instant Demo opens every world’s first scene offline, straight from the app. A live story — where every turn is new — is written by a cloud brain: the one included with your Pass, or your own key on the free version. Scene art is painted by an online image service from a one-line description of the scene. Neither is given your name or a profile. Turn on Total Privacy mode and live stories pause along with every cloud brain; the demos still play.

09 — Make it yours

Your hero. Your look. Your voice.
Your rules.

Nothing in Gestu arrives one-size-fits-all. Tailor the story before it starts, then dress the whole app and give it a voice of its own.

01 · The story customizer

Five choices before the first scene. Or none — roll the dice.

Every world opens a Customize sheet with five groups to set: in Arcane Chronicles that is your hero class, the dungeon, your starting relic, who rides with you and how the campaign plays. Add a name or a twist of your own, read the exact prompt that will run, and change any word of it before you start.

  • Surprise Me — rolls all five choices at once
  • Protagonist or custom twist — “Captain Vance, carrying a cursed compass…”
  • The prompt is yours — edit it, or reset it to your picks
  • Three ways in — Instant Demo (offline), Generate AI, or Adapt with AI Whiteboard
