You became an SLP for the therapy. Not the paperwork. SLPcentral is the app for speech-language pathologists, built by an SLP. Your caseload, your session data and your paperwork in one place, and now Ollie, your personal SLP agent. MEET OLLIE Ollie is an otter who works for one SLP: you. Text him the way you'd text a coworker. "Draft my notes from today's group." "What does my week look like?" "Help me prep for Jonah's IEP." He already knows your caseload, goals and calendar, so there's nothing to paste in. - Drafts one note per student from your own data, in the format you actually use - Asks you a quick question when something's missing, so a guess never ends up in a note - Preps IEP meetings, session plans, word lists and printable handouts - Adds calendar events and logs hours, one tap to confirm Ollie drafts and suggests. You review, edit and save. Nothing goes into a record without you. COLLECT DATA WITH ONE THUMB Big correct / incorrect targets, cue levels and frequency counts, trial by trial. Swipe between students in a group. Built to use in the room with a student in front of you. THE PROGRESS GRAPH BUILDS ITSELF Every tap becomes a graph per goal, with your baseline and target, ready for progress reports. NEVER START FROM A BLANK PAGE SOAP notes and progress reports drafted from the data you already collected, or from a quick Brain Dump after the session. Every AI draft is marked DRAFT until you review it. PRIVATE BY DESIGN Client names stay on your device unless you turn on name sync, which keeps an encrypted copy in our HIPAA-covered clinical storage. Ollie never receives your client name fields; he works with a random code like CLT_X92J. Your clinical records are stored in HIPAA-covered Google Cloud storage, and Ollie runs on Anthropic's Claude, each under a signed Business Associate Agreement, in the US only. The app auto-locks and supports Face ID and Touch ID. SLPcentral helps you meet your obligations; you remain responsible for compliance in your setting. FROM FIRST OBSERVATION HOUR TO FULL CASELOAD Observation hours for undergraduates, the 400 clinical hours for graduate students, Clinical Fellowship hours with the ASHA breakdowns. PRICING Free for students. Licensed SLPs can start free with up to 5 clients and 3 AI drafts a day, no card needed. SLPcentral Pro unlocks unlimited clients, 50 AI drafts a day and more time with Ollie. - $14.99 per month, or $149.99 per year - 7-day free trial, then $14.99/month or $149.99/year unless you cancel Payment is charged to your Apple Account at confirmation of purchase.
