For professional-exam candidates with a deadline
Tracking ≠ knowing. Bring your exam date, study effort and practice results. Inspect what the evidence supports, see what is missing, and choose one change to test.
The question
You logged the hours. Did your practice results move too? A plan records what you meant to do. Ceresis separates completed work from plans and guesses, so you can inspect the difference.
Full disclosure
How it works
Sunday evening · example week
The same week, finished
This example meets the study-time target. Hours alone cannot tell you whether you are ready to pass. Add practice results to see performance separately.
Tap the week’s figure and Ceresis lists what counted, day by day, in the words you typed. Plans, guesses and to-dos are kept but never added, and it says why. Correct any line and the figure follows.
Illustrative exam-preparation data, computed with the app’s own rules. This is an activity target, not a pass prediction or a customer result. Manual logging works without a Sensor or AI.

The same week, wound in
Each entry arrives in the order it was typed. Plans, guesses and to-dos are filed and kept, and left out of the number.
Example data
Type one line when something happens. Everything after it is automatic: the arithmetic, the plan, the review and the next step. No spreadsheet to keep, no plan to redo by hand.
Each entry updates the week against your target and the hours a week it now takes to your exam date. Plans, guesses and to-dos are kept out of the count for you.
Study logged outside the plan comes off the sessions ahead; delete a log and the session comes back. Your own edits stay.
Every Sunday or Monday: what moved, what fell short and one change to make, on every plan. On Pro, a morning brief names today’s session.
At most three, ranked: today’s open session, a re-plan when the week slips, the review when it’s due.
“Two hours of ethics, then 40 questions at 75%” is split into two entries, filed and its numbers filled in.
On Mac and iPhone, Sensor sees study blocks you didn’t type and asks you to count them. Invitation-only alpha. How it works
Pick what you need and Ceresis builds it from your target, your date and what you’ve logged. Plans stay live: tick a session and it logs itself; log elsewhere and the plan catches up. Pin one to Today, or share a tool with your group.
What’s left this week, spread over the days left in sittings of your usual size, in quarter hours.
The weekly pace from here to the date, with a checkpoint for every week.
Weigh options against what matters, scored 0 to 5. It names a best fit only when one really leads.
The same arithmetic as the app, on demand, for any amount, unit and date.
“Make me a tool that tracks which topics I’ve reviewed twice.” Pro designs a page of checklists, tables and live readings; ticking an item can log to your tracker.
On Pro: your goal, commitment, open to-dos and notes as one map, every leaf tickable or turned into a to-do.
Ceresis Sensor is an app for your Mac and iPhone that notices when you studied and offers it to your week. It is an invitation-only alpha, separate from the Free and Pro plans.
Put in your date and your plan. The weekly number it takes from here is the one Ceresis holds you to. It runs right here, with nothing sent anywhere.
Working it out…
Running in your browser on example numbers — the same code the app runs. Nothing you type here leaves this page.
This is the free plan: no AI, nothing estimated — the number you type, where you put it. On Pro, “chicken bowl, rice, greens” gets its calories and macros filled in too.
Pick a plan, drag the bodies, tilt it. Share it with someone who keeps you honest, then make it real.
Bringing the map up…
Solid bodies are on target this week; hollow ones are short. Make it yours: edit this plan
Start a group with a study partner, a running club or a writing circle. Everyone shares a scorecard (this week’s number against their own target), never their entries. Nobody is ranked. Share a week you’re proud of as a card, straight from your weekly review.

On Free, every number is one you typed. Nothing is guessed, and nothing needs AI to work.
Logging, pace, the weekly review, the map and export run on plain arithmetic. AI on Pro is an extra, never the engine.
Every tracker drawn around the goal it serves, with suggestions for what to cut, merge or pair up. Draw your own, free
Protein is “at least”, calories “at most”, sleep a range. Going over a limit is never drawn as success.
Every Sunday or Monday: what moved, and one change for next week. On Pro, a brief once or twice a day.
/ searches everything, ? asks a question of it, > compiles a date range into a spreadsheet.
Trackers for anything: pages read, cold showers, days since you last called home.
Export everything as JSON or CSVs, on any plan, any time. Delete your account and it’s gone.
$0 forever
$9.99 / month, or $74.99 / year
Founding members. The first 100 people from the waitlist who choose annual Pro pay $59.99 for their first year, then the normal annual price.
AI features have monthly allowances so the price stays flat. They reset on the 1st, and logging never stops. Past an allowance, entries are simply filed without AI.
Ceresis is Personal Objective Intelligence software that helps people understand whether their effort is translating into meaningful progress toward their goals. It is for people working toward a deadline, including exams and substantial writing projects. Tracking records what happened; Ceresis compares it with your chosen target and shows the evidence behind its reading.
The free pace calculator divides the work left by the time left. Pace checks and the Free weekly review use deterministic calculations. Pro adds AI filing, estimates, photo reading, answers and daily briefs. Access is by invitation while the waitlist is open. Sensor, for Mac and iPhone, is an invitation-only alpha and isn’t part of the Free or Pro plans.
On every plan: your pace after each log, a week plan that adjusts to what you logged, the weekly review every Sunday or Monday and up to three next steps for today. Pro also files what you type and fills in its numbers. Sensor, an invitation-only alpha for Mac and iPhone, notices study blocks and counts them once you confirm.
Yes. Install it from your browser to your home screen on iPhone or Android. It opens full-screen with its own layout, and can send your briefs as notifications.
No. Free covers logging, trackers, the dashboard, pace checks, the weekly review, search and export. Pro adds the parts that use AI: filing and estimates, photo reading, answers, daily briefs, and a weekly review written in your assistant’s voice.
No. Setup lets you fill in today and the two weeks before it, tracker by tracker, so your first pace check and weekly review compare against your real routine. Only numbers you type are saved, nothing is guessed, and you can correct them later from Settings.
Study hours, gym sessions, sleep and food come built in; switch off any you don’t want. Add up to eight of your own: a counter (glasses of water), an amount with a unit (miles, pages, dollars), a yes/no habit (no alcohol), or days since something last happened.
Yes. The demos above run the real code in your browser. The goal map and the pace calculator are free tools with no account, and nothing you type in them is sent anywhere.
You keep everything on Free. Export it or delete your account whenever you like.
