Animated preview of the BentoMind chat: reading an attached PDF offline, summarizing a chat shared from WhatsApp, an offline question, a nearby places search using OpenStreetMap, and a calculator tool call, each with live speed, CPU, memory and temperature readings.

Screen recordings of BentoMind running Qwen3.5 2B on an iQOO Z10 (8 GB RAM). No cloud, no mock-ups.
Type a question and the answer streams in, generated by the phone's own processor.
Real speed, not edited.
Attach a PDF and ask about it. The text is read on the phone and never uploaded.
About 47 s of thinking trimmed.
Speak your question; it's transcribed on the device, then answered like any chat.
A pause before sending trimmed.
New · Attach & share
Attach files from the + button, or share them from any app. Documents are read on your phone, so with an on-device model your lease never leaves it.
BentoMind pulls the text out of a PDF, a .txt, a CSV or code right on the device, so even an offline model can summarize a lease, a bill or a report.
Offline · any model “What's the notice period, and when is rent due?”
Tap Share → Ask BentoMind in WhatsApp, Gallery, Files or Chrome, or select text anywhere. Then one tap: Summarize, Draft a reply, Dates & tasks, Explain or Translate.
No SMS or storage permission “Summarize this group chat. Anything for me?”
Ask about a screenshot, a menu or a whiteboard with a vision model you connect (Ollama, LM Studio or any OpenAI-compatible API). On-device models say honestly when they can't see.
Remote vision model “What does this sign say in English?”
Features
Everything you expect from a modern AI chat, plus the one thing cloud assistants can't offer: it works with your phone's data right on your phone.
"Am I free at 4?" "Pharmacy near me." "Add Rahul's new number." "Summarise this chat." BentoMind uses typed tools for contacts, calendar, location and notifications, and you can share any text or chat to it from other apps.
No account, no analytics, no cloud chat. What you ask stays on your phone unless you choose to send it.
Honest performance: live tokens/s, CPU, RAM and temperature while you chat, plus a benchmark lab to find the model that suits your phone. Export results as CSV or JSON.
On a flight, in the mountains, or on a patchy connection. Once a model is downloaded, chat, local voice input and on-phone tools like contacts and calendar work in airplane mode. No per-query cost, ever.
Speak instead of typing. Use Google's on-device recognizer, or a fully local Moonshine or Whisper model.
speech → text on your phone · from 28.5 MB
Auto thinking reasons only when it helps (math, code, planning). A budget and loop detection stop small models from going in circles.
Off until you turn it on. Then ask it to remember something and it saves a short, editable note on your phone. View, edit or delete any memory at any time.
Pick from 20 open-weight models sized for your phone, from 292 MB to 3.1 GB, with a device-fit badge on each. Paste any GGUF link from Hugging Face. Or connect an OpenAI-compatible server you trust, such as Ollama on your laptop; API keys are encrypted on the device.

Privacy
The model runs on your phone's CPU, so your questions, chats and personal data are processed in your pocket. Data only crosses the line for things that need the internet, and you control each one.
No account, no chat server
There is nothing to sign up for and no BentoMind backend that sees your chats. We only receive a reply you choose to report.
No ads, analytics or trackers
No tracking SDKs in the app. Your data is never the business model.
Only the minimum, under your control
Web search sends just the query and can be switched off. Nearby places sends an area rounded to about 100 m.
Delete anything
Clear chats, memories and models in the app. Uninstalling removes everything.

Models & performance
No cherry-picked flagship. Every figure below was measured with BentoMind's llama.cpp engine on an iQOO Z10 (Snapdragon 7s Gen 3, 8 GB RAM).
Decode speed, higher is better Prompt processing, higher is better Time to first token, lower is better
Q4_K_M / Q8_0 GGUF. MiniCPM5 and LFM2.5: benchmark lab, 4 threads, 4 Oct 2026. Qwen3.5: llama-bench with the app's 4 prompt / 3 decode threads, 10 Oct 2026. *In a real chat, Qwen3.5 2B (the default on 6 GB+ phones) streams at about 7.6 tok/s. Decode speed is limited by memory bandwidth, so smaller files are faster.
