Free online tools
Privacy-first tools for neurodivergent minds — sensory and regulation support, communication boards, honest self-understanding tests — plus the developer utilities the site is built with. Nearly everything runs in your browser and your data stays on your device; the two kinds of scoring tools send answers once, server-side, for interpretation and store nothing (spelled out in /cookies/).
Sensory & Regulation — for neurodivergent minds
Free, no-signup, local-first tools for autistic and neurodivergent people. Research-cited, honest about limits — and your data (mic audio, check-ins, history) never leaves your device. Every tool has one-click export and delete.
Sound Level Meter
Live loudness + the frequency bands research links to auditory overload (250 Hz, 8 kHz). Mic audio never leaves the page.
Rests on: Antecedent-based intervention — 49 studies: measuring the environment in order to change it.
Noise Mask (white / pink / brown)
Free, offline noise generation with an honest tolerance check — masking helps many, not everyone.
Rests on: Antecedent-based intervention — 49 studies, changing what comes before rather than what follows.
Sensory Overload Meter
One visible number for sensory load that learns YOUR personal threshold from feedback. Local-only history.
Rests on: Self-management — 26 studies, as a noticing aid. It rates how things feel; it does not diagnose anything.
Breathing Pacer
Visual coherent / box / 4-7-8 pacer with a reduced-motion fallback. No streaks, no notifications.
Rests on: Exercise and movement — 17 studies, which covers paced breathing and mindful movement.
Stress Check-In
60-second check-in that turns vague stress into a visible gauge + your own coping list. SAM-mechanism, RCT-cited.
Rests on: Self-management — 26 studies: noticing your own state, then recording it.
Recovery Mode
A deliberately near-empty page for meltdowns and shutdowns: dim, one line at a time, safe stops.
Rests on: Antecedent-based intervention — 49 studies: arranging the environment so a hard moment is less likely to build.
Calm Corner
Feeling-first regulation for kids and grown-ups: pick a feeling, get a matched calming activity. Web edition of the Neuro-M app experience.
Rests on: Cognitive behavioural/instructional strategies — 50 studies: name what you feel, then use a step-by-step response.
Heartbeat Anchor
A slow synthesized heartbeat to ground on — visual pulse, optional sound, color you can change.
Rests on: Exercise and movement — 17 studies, for mindful movement. Deliberately not an interoception-accuracy claim: a 2025 meta-analysis of 31 studies found no such difference in autistic adults.
Busy Board
Nine fidgets in one board; every sound synthesized live. From the Neuro-M app family.
Rests on: Visual supports — 65 studies, for a visual display that carries a routine without extra prompts.
Sensory Canvas
Sand, water, slime, glow, sparks, fireworks — a canvas that answers your hands.
Rests on: Not built on a named evidence-based practice.
Sensory Gravity
A tiny physics world: balls, confetti, snow, bubbles. Tilt to steer.
Rests on: Exercise and movement — 17 studies, for movement-based regulation.
Flow & Create
Ten gentle brushes from pen to galaxy. Saves stay on your device only.
Rests on: Not built on a named evidence-based practice.
Communication & Needs — say it, choose it
Boards that speak for the person tapping them — needs, core words, phrases, choices. Everything runs in your browser, every photo and choice stays on this device, and the voice is your browser's own. From the Neuro-M app's communication family.
My Board
Tap-to-speak needs & core-words board with a gentle wait timer and room for your own photos. From the Neuro-M app family.
Rests on: Augmentative and alternative communication — 44 studies, which includes speech-generating boards and the coaching that teaches their use.
Yes & No
Two giant buttons for the hardest moments — tap and the device says it. No setup, bookmarkable, nothing stored.
Rests on: Augmentative and alternative communication — 44 studies: a yes or a no is the smallest possible utterance a board can support, and often the first one.
Visual Schedule & Routine Builder
Step-by-step visual routine builder & First/Then board with voice prompts and printable layouts. 100% browser-based.
Rests on: Visual supports — 65 studies; visual schedules are named in the practice description. Task analysis (13 studies) also applies.
My Choices
A first-then choice board: build a 2-4 step path, tap to hear it spoken, show it big for a grown-up.
Rests on: Antecedent-based intervention — 49 studies. Learner choice is named directly in the practice definition.
Ask & Wonder
Phrase board - 'I'm hungry', 'More please' - plus gentle facts for curious kids. Speaks with your browser's voice.
Rests on: Augmentative and alternative communication — 44 studies. A phrase board with spoken output is the aided-communication practice the review describes.
Video Board
A 'what to watch' choice board: plain labels you replace with your own photos; taps speak the pick.
Rests on: Visual supports — 65 studies: concrete cues for choosing an activity.
Voice Notes to Text
Speak a note and get editable text you can keep. For when talking is easier than typing — and for catching a thought before it goes. Nothing stored by us.
Rests on: Not built on a named evidence-based practice.
Play & Cause-Effect — tap, watch, giggle
Gentle play for little hands and busy minds: cause-and-effect games, music you can't play wrong, and toys that answer your touch. No fail states, no timers pressuring anyone, every sound synthesized live in your browser. From the Neuro-M app's play family.
Tap Pop
Tap the critters before they hide — a gentle reaction game. All sounds synthesized live. From the Neuro-M app family.
Rests on: Not built on a named evidence-based practice.
Pattern Follow
Watch the pattern light up, tap it back — musical Simon-style play with no fail states.
Rests on: Modelling — 28 studies: a demonstration, then the learner performs it.
Worm Maze
Guide the worm to the fruit with a finger — a gentle canvas motion game that grows with every bite.
Rests on: Not built on a named evidence-based practice.
Music & Sounds
A tap-to-play xylophone with five gentle instrument voices and a bubble mode. No wrong notes.
Rests on: Music-mediated intervention — 7 studies.
Melody Bubbles
Tap rising bubbles to play melodies — five instrument timbres, endless gentle play.

Harmony
Touch and move to create symmetrical magic on a canvas — mirrored strokes that glow and bloom.
Rests on: Music-mediated intervention — 7 studies, the thinnest evidence base of the practices cited on this site.
The Unmasking Suite — competence, cost, and coming back to yourself
Seven tools for the slow work of taking the mask off: see your camouflage pattern, see where you bend, read stress as competence, catch burnout early, budget your energy, and climb back toward your own preferences — one safe step at a time. Self-authored, research-cited, never a diagnosis; interpretation is computed server-side, everything you track stays on your device. Read the companion essay →
Camouflage Profile
Self-authored masking-effort assessment (Compensating / Concealing / Conforming) with a named profile — grounded in published research, not any copyrighted questionnaire. Server-side scoring.
Rests on: Not built on a named evidence-based practice.
Preference Map
Maps natural preferences against performed ones across five axes; the gap is the Bend — where masking spends you. Type-curious readers recognize the shapes; no branded type anywhere.
Rests on: Antecedent-based intervention — 49 studies, for incorporating learner choice into what happens next.
Signal Decoder
Stress-as-competence reframing: describe a response (frozen, blue screen, long crash) and read what the system was competently doing and what it needs now. Cited, safety-railed.
Rests on: Self-management — 26 studies, for discriminating between states and recording them accurately.
Early-Warning Tracker
A weekly check-in against the published autistic-burnout early signs, with a local trend and honest banding. Not a screener — a self-knowledge tool with crisis signposting.
Rests on: Self-management — 26 studies, which is exactly this: noticing and recording your own signals.
Energy Ledger
Budget the charge: log drains and recharges, tag the masking costs, get an honest reading. Spoon-theory lineage credited, own units.
Rests on: Self-management — 26 studies, for self-monitoring and self-recording over time.
Unmasking Ladder
Gradual, safety-first micro-practices ordered by stakes for the contexts you pick. Unmasking is not disclosure everywhere; every rung is opt-in.

Interest & Flow Map
Monotropism-informed recharge mapper: name your attention tunnels, get a flow profile and a recharge menu. Deep interests are legitimate needs.
