Free EMDR Tool for Online Bilateral Stimulation

Test the full bilateral stimulation engine in your browser without an account, then run a real client session on the Free plan. This page explains exactly what is free and what is not.

DEFINITION

BilateralSync is a browser-based EMDR tool that delivers therapist-controlled visual and auditory bilateral stimulation to a client's own screen. It can be tried free without an account through the public demo, and the registered Free plan includes one real client session per calendar month.

What the tool is

BilateralSync renders the moving visual target and alternating stereo audio used for bilateral stimulation (BLS) during EMDR therapy. The therapist operates the controls on their own screen; the client sees only a clean fullscreen stimulation view on theirs, kept in step in real time.

Who it is for

Licensed EMDR therapists, psychologists and psychotherapists who run sessions online, in the room, or both. It is a clinician tool: it is not a self-help application and is not intended for unguided reprocessing.

Demo, Free plan and Professional — what is actually free

Three levels exist, and they are deliberately distinct:

  • Demo — open the live demo and use the real stimulation engine immediately. No account, no card, no client link. Use it to evaluate patterns, speed and audio before you commit anything.
  • Free plan — create a therapist account and run 1 real client session per calendar month at no cost, with the full stimulation engine and the full client view. No card required.
  • Professional — unlimited sessions, saved presets and session history for €12/month or €120/year, cancellable at any time. See pricing.

The Free plan is not unlimited. It exists so you can run a genuine session with a real client before deciding whether the tool belongs in your practice.

Visual bilateral stimulation

Seven visual patterns — horizontal, vertical, diagonal, circular, infinity, pendulum and smooth random — with live speed, size and colour control. Horizontal remains the standard default; the rest accommodate visual comfort and clinical preference. More detail on visual BLS and on the virtual EMDR light bar approach.

Auditory bilateral stimulation

Stereo-panned tones alternate between the left and right channel, with adjustable frequency, panning depth, volume and speed. Headphones are required — laptop speakers collapse stereo panning to mono. See auditory BLS.

Therapist-controlled client view and real-time sync

Every adjustment the therapist makes is applied to the client's view in real time, so pattern, speed and audio changes land without asking the client to do anything. The client's screen shows the stimulation only — no controls, no chrome. See synchronization and therapist controls.

Browser-based delivery, supported devices

The tool runs in any current version of Chrome, Edge, Safari or Firefox on Windows, macOS, ChromeOS, iOS and Android. Nothing is installed on either side and the client never creates an account, which removes the most common setup failure in online sessions. Background on browser-based EMDR.

How to start

Open the demo and try the engine. If it fits your workflow, create a free therapist account, start a session, and send the generated link to your client alongside your usual video platform — Zoom, Teams, Doxy.me or Google Meet. See remote EMDR for the full session workflow.

Frequently asked questions

Is BilateralSync a free EMDR tool?

Partly. The live demo runs in your browser with no account, and the Free plan includes one real therapist-led client session per calendar month at no cost. Unlimited sessions require the Professional plan.

What can I test without signing up?

The public demo gives you the actual bilateral stimulation engine: all 7 visual patterns, speed, size and colour controls, and stereo auditory BLS. It does not create a client session link.

How many free sessions do I get?

The registered Free plan includes 1 real client session per calendar month, resetting at the start of each month. Professional removes the limit for €12/month or €120/year.

Do clients need an account or a download?

No. The client opens a session link in any modern browser. There is no client account, no app store and no installation.

Is a free EMDR tool suitable for clinical work?

The stimulation engine is the same on Free and Professional, so the clinical experience is identical. The Free plan differs only in session volume, saved presets and session history.
