ATTACH IMAGES & FILES Pick a photo from your library or attach a text or PDF file directly to your message. Vision-capable models can analyze images; text files are embedded as context so the AI understands your documents. SMART SYSTEM PROMPTS Choose from built-in prompt templates -- General Assistant, Blog Writer, Code Expert, Translator, Academic Editor, Creative Writer -- or craft and save your own. Each conversation can have its own persona. PER-CONVERSATION PARAMETERS Fine-tune Temperature, Max Tokens, Top-P, and streaming mode for every chat independently. Add custom key-value parameters for advanced API features without touching a single line of code. MCP TOOL INTEGRATION Connect external tools and data sources via the Model Context Protocol (MCP).

Dark mode and Dynamic Type are fully supported. YOUR DATA, YOUR CONTROL Thinklet stores everything -- conversations, settings, API keys -- locally on your device using iOS secure storage. No account, no cloud sync, no telemetry. Whether you are a developer experimenting with the latest models, a writer looking for a creative partner, or a professional who needs a capable AI assistant on the go, Thinklet gives you the flexibility and power you need, beautifully packaged for iPhone.

About

SoloNote

Some notes are nobody else's business. SoloNote is the AI notebook that keeps it that way: the model lives inside the app, so the thinking happens on your iPhone โ€” not on somebody's server. No account. No subscription. No cloud copy of your life. Put your phone in aeroplane mode and the AI keeps working. Try that with any other AI app. NEW: A SCREENSHOT BECOMES A PLAN Screenshot a flight, a train ticket, a hotel booking or a clinic appointment โ€” or share it straight from another app โ€” and SoloNote reads it on your iPhone. Times become reminders (for a ticket, the evening before and two hours before departure), places go on a trip, and "payment due" lines become to-dos. One card, one tap to save, one tap to undo. A time SoloNote isn't sure about starts switched off, so nothing rings at the wrong hour. NEW: TODAY, ON ONE PAGE Reminders, to-dos and the trip stops planned for each day, gathered in one place with the next thing on top. Every Sunday evening, a short summary of your week arrives as a note. NEW: RECEIPTS THAT ADD THEMSELVES UP Capture a receipt or a payment screen and it goes straight to Spending, not into your notes โ€” totalled by month and by category, one total per currency. The amount, shop and date are read by rules, never guessed by the AI. SEARCH & ASK, HONESTLY Search finds every note containing the words you type. Ask a question and tap "Answer from your notes": SoloNote answers from your own notes and shows the notes it used. When the answer isn't there, it says so instead of guessing โ€” and when your notes hold two possible answers, it shows you both. NOTES AS RICH AS YOUR THINKING Photos exactly where they belong, bold, headings, lists, checklists that tick with a tap, links. Formatting is a button โ€” you will never see a markup character. TALK FASTER THAN YOU CAN TYPE Tap once and speak. Your words land on the page as you say them. TIDY THE 2 A.M. SCRIBBLE One tap turns a rushed note into a clear one without changing what you meant โ€” and Restore puts the original back. When a note is already fine, SoloNote says so instead of inventing a rewrite. SCAN IT, IMPORT IT, IT'S A NOTE Import a PDF, Word file or photo of a page and SoloNote turns it into an ordinary note โ€” read on your device, tables and all โ€” that you can search and ask about. "DENTIST ON TUESDAY" BECOMES A REMINDER Write a date and SoloNote offers a reminder in one tap โ€” and, if you like, adds it to your calendar too. SCRIBBLED PLACES BECOME A ROUTE List the places you want to visit, or let SoloNote read them from a note, and get a mapped, ordered trip with the walking or driving time between stops. One tap hands the route to Apple Maps or Google Maps. SOME NOTES HIDE Swipe to lock a note and it vanishes from your lists, your search and Today. Face ID โ€” or your passcode โ€” brings it back. FREE MEANS FREE No ads, no paywall, nothing to unlock, nobody to sign in as. The download is large because the AI comes inside the box. PRIVATE BY DESIGN โ€ข Your notes, photos, screenshots and documents are read and kept on your device. โ€ข No account and no sign-in โ€” ever. โ€ข Two features use Apple Maps. Trips sends what you type when adding a stop (that is how places are suggested), plus your location if you add it as a stop. Capture, only if you allow it when it first asks, sends the names and addresses of places it found โ€” never the screenshot or the rest of its text; a receipt with no upcoming date looks nothing up. Opening a trip in Google Maps sends that trip's stops to Google. Your notes never leave. โ€ข Anonymous usage statistics help us improve SoloNote, and can be switched off in Settings. Your thinking deserves a room of its own. This is it. SoloNote is available in English, Japanese, Simplified Chinese and Traditional Chinese.
