The phone's next
interface layer.
StareBrain turns plain language into confirmed, on-device action — whole jobs done, like a cancelled flight rebooked or a dispute filed. We're raising a pre-seed to take a nearly finished product through security review and into a 20-person beta.
Every phone already has hundreds of apps on it.
None of them talk to each other, and all of them cost taps.
StareBrain replaces the tapping with one sentence.
One interface, confirmed before it acts, sitting on top of everything else.
Same phone. Different interface.
The wedge
Command interfaces (Rabbit R1, Humane) tried to sell new hardware. StareBrain skips the hardware problem — it's software on the phone people already carry.
The timing
On-device and API LLMs are finally fast and cheap enough to sit in the critical path of a phone action without breaking the UX.
The wedge user
Power users and busy professionals first — the segment that already strings together Shortcuts, Tasker, and third-party automation to save minutes.
Free to prove it works. Paid once it's indispensable.
Free
Launch ships free to build usage data and a beta cohort of ~20 power users.
Freemium
Core workflows stay free; advanced multi-step agentic workflows and integrations become the paid tier.
Platform
Third-party app integrations (Canva, CapCut, email) open a distribution channel other apps pay to be inside.
Not an idea on a slide. A build in progress.
Agentic workflows
Multi-step jobs that chain actions across messaging, calendar, apps and device — not single commands.
Stack chosen
Kotlin + Compose on Android with an accessibility-based agent, FastAPI + SQLAlchemy backend (PostgreSQL-ready), multi-provider LLM reasoning (Groq, NVIDIA NIM, Gemini, OpenRouter).
Security-first design
Plan confirmation (texts always ask), pause before irreversible taps, a built-in block list for photos and files, and history kept on the phone.
Almost done
Working Android app and backend. Remaining: personal accounts, security hardening (including certificate pinning), and beta onboarding.
The ask — pre-seed, currently open
Almost all of it goes into the build.
Engineering
Personal accounts, backend + Android hardening ahead of launch.
LLM & infra
LLM API usage (Groq, NVIDIA NIM, Gemini, OpenRouter), hosting, database, monitoring.
Security review
Third-party audit before public beta.
Beta & GTM
Recruiting and running the first 20-user beta.
Let's talk before the beta fills up.
