One workspace per student

A student’s session list in Sightline: four observations grouped by month, each tagged with the method that produced it, its duration, and the behaviors recorded.

The second observation of a student shouldn’t start from scratch. Every session, result, comparison, and draft for one student stays in a single workspace, so a case builds instead of scattering.

One session. Eight ways to score it.

Every method is a different reading of the same ten minutes. Choose one and Sightline changes the clock, the scoring controls, the event record, and the results around it. No rebuilt spreadsheet for every referral.

The same ten minutes, eight different results. Choosing the method is choosing what the record can say.

All eight methods are included in Free.

One tool, from the first interval to the write-up.

Standard practice runs a single observation through a paper sheet, a timer app, a spreadsheet, and a word processor. Every handoff is a chance to mistype a number or lose the context that explained it. Sightline keeps the session, its results, and the write-up in one place, entered once.

  1. Observe

    The record is finished when the session is.

    Score by keystroke while the clock runs. The activity, the session notes, and the timestamped log stay on one screen.

    The Sightline recording screen during a partial-interval session: a running interval clock, the current activity, scoring controls for two behaviors with their interval grids, and session notes and a timestamped observation log beside them.

  2. Analyze

    See whether the pattern holds.

    Place sessions on one chart, keep their settings and activities attached, and inspect the change without flattening separate observations into one blob of data.

    Sightline’s cross-session comparison for one student: fifteen observations plotted across a baseline phase and a self-monitoring phase, separated by a phase line, with off-task at 59.3 percent during baseline and 23.0 percent afterward.

  3. Report

    The draft opens beside its evidence.

    Pro drafts the write-up locally from the data you coded, and the draft sits next to that data. Every figure in the prose can be checked against the session that produced it before you revise and sign.

    The Sightline write-up workspace: an editable draft describing the observation on the left, with the session’s notes, per-behavior percentages, and occurrence chart on the right.

iPhone companion

Continue recording, untethered.

Need to move around the room, record outside, or step away from the computer? Use your iPhone to score behaviors, mark activity changes, and capture notes.

Paired live
Scores, activity changes, and notes land in the desktop session while you move around the room.
Untethered
Step away from the computer and the observation stays on the iPhone, transferring when your devices reconnect.
Voice notes
Capture a note mid-session. Audio follows the same local path and is transcribed on the desktop, not by a cloud service.
Silent haptics
Every score you enter is confirmed by a tap you can feel, so the phone stays quiet in the room.

Apple Watch coming this fall.

Explore Companion

The AI that drafts your write-up runs on your computer.

It works from the record you coded: a write-up drafted for you to edit, session summaries, and function hypotheses, with every figure traceable to the session that produced it.

Anything that sends student records to a company carries a data-sharing agreement your district has to put in place first. Sightline never sends student data anywhere, so there is nothing to put in place.

Download it and start. Sightline never sends a student’s record anywhere, on the trial or ever after.

Why we built it this way
Your computer
  1. Observation record
  2. Structured analysis
  3. Local model
  4. Draft for review
The internet

The app, the model, updates

Student data: nothing, ever

The practitioner stays responsible. Sightline drafts and analyzes; reviewing the language against the record, and signing what you send, remain professional judgment.

No FERPA disclosure to manage

Sensitive work belongs on devices you control.

Student information, observations, notes, recordings, analyses, and reports stay on your devices. Sightline runs AI locally and doesn’t operate a cloud for your records.

Buying your own tool? This difference is most of what you are buying. There is no data-sharing agreement to chase and nothing lands on someone else’s servers, on the trial or ever after.

Sightline’s automatic internet connections are limited to licensing, updates, and model downloads. They are designed not to include student-record content. District policy still governs approval, access, consent, retention, exports, and disclosures.
