Lay the pencil down.
The tip still leads. Pressure rises away from it across the exposed core, creating the long side-contact gradient an artist expects from real graphite or colored pencil.
An Android drawing studio
Haneハネ
Made for the hand.
The paper pushes back. Graphite turns on its side. Water moves pigment. A brush remembers the color it picked up. Hane is a stylus-first drawing studio powered by Tiltmark, Sloom’s physical-media engine.

01 · drawing feel
Not a stamp.A contact.
Tiltmark follows the chain from hand to implement to paper. The footprint, carried material and surface state persist together, so the mark changes for a physical reason—not because a texture was swapped behind the scenes.
The brush keeps what it carries.
Pigment, vehicle, contamination and wetness continue across strokes until you load, wipe, rinse or choose a different reset policy.
See the contact before it lands.
The hover cursor uses the same authored geometry as the stroke: footprint, azimuth, side contact and active-layer transform.
Your session is a working state, not a fragile moment.
A bounded recovery journal runs away from the input task and preserves acknowledged work through interruption. Files stay local and remain yours.
02 · material studies
Every medium hasits own contract.
Solids deposit. Liquids can mix. Pickup-only tools begin empty. Hane does not force every implement through one generic “paint brush” behavior.
Graphite
Point and shoulder are one continuous contact. Lower the pencil and pressure rises from the point across the side, leaving a tooth-broken gradient instead of a larger round stamp.

03 · the instrument
Quiet UI. Deep material.
Hane keeps the canvas central. The active implement itself becomes the status display and the place to adjust what matters.
The implement is the interface.
A pencil shows point, grade and remaining core. A wet brush shows carried color, concentration and vehicle. Controls live in the implement body, not behind a generic settings button.
Clean tools start clean.
Stumps, swabs, colorless blenders and solvent tools begin without pigment. They can lift and carry color from the artwork, but they never invent a dark fallback color.
Physics belongs to the artwork.
Stroke geometry, reservoirs, pigment and vehicle mixing, solid-media wear, substrate contact and compatibility live in one deterministic Rust engine. The interface presents that state; it does not reinterpret it.
Performance cannot buy lower fidelity.
Hane may coalesce disposable presentation work, but it does not throw away source samples, lower the physical detail grid or simplify the final artwork to make a benchmark look better.
Local files. No model prompts.
Hane is a focused drawing product, not a generative-AI surface. Your artwork and recovery state remain on your device unless you choose to export or connect to Sloom Studio.
Digital drawing should feel less like choosing an effect—and more like handling a material.

Asked by artists.
Is Hane available now?
Hane is in active development and device qualification. We are not
announcing a public release date until drawing feel, memory, recovery and
sustained stylus use meet the release gates. Join the release list below for
the real announcement.
Is Hane an AI drawing app?
No. Hane is for drawing and painting by hand. It has no prompt box,
generative model or included AI service. Sloom Studio can provide optional
connected workflows elsewhere, but they are not Hane’s identity.
What hardware is it designed for?
Hane is designed first for stylus-capable Android devices, including
pressure- and tilt-aware S Pen hardware. It uses the axes a device truly
provides and offers compensation for directional tools when barrel rotation
is unavailable.
How are Hane, Tiltmark and Sloom Studio related?
Hane is the focused Android drawing app. Tiltmark is the physical-media
engine inside it. Sloom Studio is the larger creative environment—Image,
Paper, Flow and Video—and is gaining the same Tiltmark engine for connected
desktop and publication workflows.
Will Hane use ads or a subscription?
Hane is being built without ads and around ownership rather than recurring
rent. Final availability and pricing will be published when release
qualification is complete; we will not reduce brush fidelity to create a
permanently crippled edition.
