Comparison
Schedull vs Tiza
Tiza is a web timetable generator with a genuinely usable free plan, spreadsheet import, room assignment and collaboration on a project, priced per month or per year in three tiers it publishes in full. Schedull is a web timetable generator with no free plan, a six-level availability scale, a feasibility check before generation, and a substitutions workspace for the rest of the school year. Tiza is the easier product to evaluate for nothing; Schedull covers more of what happens once the timetable is in use.

Best fit
Both are worth evaluating if your school wants online timetable generation. The split is between Tiza's free-tier model and shared projects, and Schedull's availability model and the work that comes after generation.
| Need | Better fit | Why |
|---|---|---|
| Evaluating a real timetable for nothing | Tiza | Tiza's free plan allows 3 projects of up to 30 classes, 10 generations a month and 10 AI prompts a month. Schedull has no free plan. |
| Colleagues entering and validating data together | Tiza | Tiza describes collaboration on a project for data input and validation. In Schedull a project has one owner and cannot be shared. |
| Absences and cover once the year has started | Schedull | Schedull publishes a timetable to a shared calendar and runs a substitutions workspace on top of it. Tiza does not describe absence or substitution management. |
| Availability that is a matter of degree, not a yes or no | Schedull | Schedull grades every period on six levels from unavailable to strongly preferred, for teachers and for rooms. |

| Area | Schedull | Tiza |
|---|---|---|
| Deployment | Web app in the browser. Nothing to install and nothing to keep in sync between machines. | Web app in the browser, no installation. |
| Interface languages | English and Spanish. | Not stated on the public pages. |
| Setup and data entry | Guided setup with four starting points: from scratch, from a template, from a spreadsheet, or from last year's project. | Web setup with hundreds of customisable requirements and constraint types. |
| Imports | Excel, OpenDocument, CSV and zip files, plus reverse import that rebuilds classes, subjects and teachers from a finished timetable grid. | Upload existing information from spreadsheet software instead of typing it in. |
| Teacher availability | Six levels per period, from unavailable through neutral to strongly preferred, so part-time patterns and mere preferences are not the same input. | Covered by its requirements model. Detail is not published as a separate availability scale. |
| Mandatory rules and preferences | Mandatory rules and weighted preferences at subject, class and teacher level: avoid a period, avoid a day, cap lessons per day in periods or minutes, keep lessons consecutive, same break for every class, tutor obligations, reduce teacher gaps. | Hundreds of customisable requirements and constraint types, with priorities. |
| Split groups and co-teaching | Split groups run in parallel with their own teacher and their own allowed rooms; a lesson can also require two or more teachers at once. | Not described as separate concepts on the public pages. |
| Classrooms and buildings | Allowed rooms per subject and per split group, room availability on the same six-level scale, and movement penalties between buildings. Professional and Premium. | Automatic room assignment based on the options given and the fit with the timetable. |
| Before generation | A feasibility check runs first and blocks a run that cannot succeed, naming the class, teacher or room that makes it impossible. | Not described as a separate pre-generation check. |
| After generation | A run report lists every preference the timetable had to break, so the result can be judged instead of just accepted. | Generation history is a Premium feature; the AI assistant answers questions about the result. |
| Manual editing | Conflict-checked drag and drop, with edit sessions you can leave and resume before committing. | Timetables can be adjusted in the browser after generation. |
| Daily substitutions | Absence workspace on top of the published timetable: record an absence over a date range, see the lessons it hits day by day, and resolve each one with cover, supervision, a merged class, a cancellation, or no action. Cover suggestions are ranked and say why. No notifications yet. | Not described on the public pages. No absence or substitution management. |
| Sharing and publishing | Publish a timetable to a shared day, week and month calendar inside the app. There are no public links and no student or family portal. | Collaboration on a project for data input and validation. No shared operational calendar described. |
| Exports | Excel, OpenDocument, PowerPoint, PDF, PNG zip and CSV zip, by class and by teacher. Professional and Premium; Basic cannot export. | Exports are excluded from the free plan and included on Pro and Premium. |
| AI assistance | An assistant that turns a plain description into draft setup and rules, always as a change set you apply or discard. Metered at 5, 20 or unlimited messages a day by plan. | AI timetable generation, plus a metered AI assistant: 10, 50 or 100 prompts a month by plan. |

Strengths and limitations
Where Tiza is stronger: its free plan is generous enough to build a real timetable for a small school before paying anything; colleagues can collaborate on a project to enter and validate data, which Schedull cannot do; monthly billing means a school can pay for the months it plans in and stop; and it advertises hundreds of customisable requirements.
Where Schedull is stronger: teacher and room availability is graded on six levels rather than set once; a feasibility check refuses an impossible run and names the cause instead of leaving it to a generation attempt; a run report lists every preference the timetable broke; a project can be rebuilt from a finished timetable grid, not only from a spreadsheet; the timetable can be published to a shared calendar and absences covered from it; and exports run to six formats rather than an unspecified set.
Which should you choose?
Choose Tiza if you want to build a real timetable before spending anything, if more than one person will enter and validate the data, if you would rather pay monthly than commit to a year, or if your school is small enough to live inside the free plan's 30 classes.
Choose Schedull if teacher availability in your centre is a matter of degree, if you want to be told a timetable is impossible before waiting for a run, if you need to import last year's finished timetable rather than a clean spreadsheet, or if the timetable is only the start and you also have to publish it and cover daily absences.
FAQ
Does Tiza have a free plan?
Yes. Tiza's free plan allows 3 projects with up to 30 classes, 10 generations a month and 10 AI prompts a month, with exports excluded. Check those limits against your class count and export workflow: a school past 30 classes or one that has to hand out PDFs will need the Pro tier. Schedull has no free plan; it offers a free week of Premium with a card. Checked 25 August 2026.
Does Tiza handle teacher absences and cover?
Not as far as its public pages describe. Tiza documents timetable generation, import, room assignment, collaboration and export. Schedull publishes a timetable to a shared calendar and runs a substitutions workspace on top of it, with ranked cover suggestions that say why each teacher is proposed. If daily cover is part of your job, verify this directly with Tiza before deciding.
Can colleagues work on the same timetable?
In Tiza, yes: it describes collaboration on a project for data input and validation. In Schedull, no: a project has a single owner and there is no way to invite anyone. If your school splits timetable work across a department, this is a real advantage for Tiza.
Which should I test first?
Test the one that matches your current data and export needs, then compare the results using the same school scenario in both. Include teacher availability, shared specialist rooms and at least a few real mandatory rules, so the trial reflects the conflicts your team actually handles rather than a clean sample.
