Orchesia
Orchesia is a French web app that structures projects before scheduling them. Its AI builds a work breakdown structure, proposes task dependencies and computes the critical path, then generates a Gantt schedule you review and adjust.
What is Orchesia?
Orchesia is a browser-based project management application published in France by the sole trader Pierre ABOUCAYA, trading as Orchesia and registered with the national business register on 3 April 2025 in Marquette-lez-Lille. Its argument is that the real lever is not going faster but starting better, so the product deliberately targets the framing stage rather than execution, replacing lists and spreadsheets with interactive, AI-assisted diagrams.
The software offers two modes in one subscription. In structured mode you begin from the content of the project: a collaborative mind map breaks the idea into objectives, deliverables and tasks, a dependencies view establishes what blocks what, the critical path is computed, and a schedule is generated that you can then adjust. In simplified mode, meant for a date already imposed, you work backwards from the deadline to place phases and milestones, prioritise each phase's deliverables in a Kanban, then assign people and hours in cycle planning and verify that the load stays within the team's capacity across all projects. Gantt, Kanban, calendar and dashboard views are available on both paid plans.
The AI, which runs on Anthropic's Claude models declared in the sales terms, does four things: it generates a full work breakdown structure from a one-sentence brief, proposes dependencies, computes the critical path, and predicts the tasks missing from a structure you have already started. The vendor is explicit that the assistant only suggests and that the user validates or rejects every step, so nothing about the structure is decided automatically. Assistance is metered in AI credits allocated per workspace rather than per seat: two credits to create a project, one for a subtask suggestion, one for a dependency suggestion, and nothing is charged when an operation fails.
Onboarding is claimed at under fifteen minutes for a first project. The site is fully bilingual French and English, and is organised around eight sector pages, seven role pages, five competitor comparisons and roughly forty methodology articles.
What it does
- Generate a complete work breakdown structure from a one-sentence description of the project
- Propose the logical dependencies between tasks and compute the critical path automatically
- Predict the tasks missing from a structure you have already started building
- Break an idea down into objectives, deliverables and tasks in a collaborative mind map
- Work backwards from an imposed deadline to place phases and milestones
- Assign people and hours by drag and drop, then check workload against team capacity across every project
- Produce and adjust a Gantt schedule derived from the structure rather than typed in by hand
When to use Orchesia / When not to
A quick filter to help you decide if Orchesia is the right fit.
When to use Orchesia
- Project managers and project schedulers who have to commit to a delivery date and then hold it, and who need the dependencies and the critical path settled before the schedule is opened
- PMOs, business analysts and operations managers who arbitrate workload against team capacity across several projects at once
- Small delivery teams of up to twenty people in web and communication agencies, engineering offices, construction, audiovisual production, video game studios and event organisers, all sectors the vendor addresses with dedicated pages
- Founders and independent consultants who need to turn a rough idea into a defensible plan quickly, without buying an enterprise suite
- Teams currently planning in spreadsheets, who lose dependency visibility and real-time collaboration and want a first structure generated from a one-sentence brief
When not to use Orchesia
- Organisations above twenty seats: the top plan caps at twenty users, twenty projects worth of headroom and 150 tasks per project, and no enterprise or quote-based tier exists
- Teams that need the planning tool wired into their stack: no public API is offered and the site names no third-party integration at all, neither chat, ticketing nor calendar
- Anyone who needs to work from a phone or a desktop client: Orchesia is a browser application only, with no mobile or offline version
- Buyers who require a security certification such as ISO 27001, SOC 2 or an audited hosting commitment before signing, since none is claimed
- Heavy AI users: assistance is metered in monthly credits that cannot be topped up, so generation stops until the quota renews
How to use Orchesia
A typical end-to-end flow, from setup to results.
- Open the free trial from the website: registration on app.orchesia.com starts a thirty-day trial with every feature unlocked and no card required
- Describe your project in one sentence and let the AI produce a first structure, or start from a blank mind map if you prefer
- In structured mode, clarify the scope by breaking the project into objectives, deliverables and tasks in the mind map
- Move to the dependencies view to establish what blocks what and let Orchesia compute the end date and the critical path
- Review the generated schedule, adjust it, and use it to steer the project once it launches
- In simplified mode, start from your fixed deadline and work backwards to define the major work phases and milestones
- Prioritise each phase's deliverables in the prioritisation Kanban so you can see at a glance what to drop if time runs short
- Assign people and their hours in cycle planning by drag and drop, then check workload against capacity across all your projects
- Invite stakeholders on visitor seats, which allow reading and commenting but no editing
- At the end of the trial, choose Standard or Premium inside the application, or let the workspace fall back to the free tier
Pros & Cons
Pros
- An unusual position: the AI is put to work on upstream framing, producing a work breakdown structure, dependencies and a critical path rather than yet another checklist
- The assistant suggests and the user validates step by step, an explicit guardrail against structures nobody checked
- Two complementary planning modes in a single subscription, whether the deadline still has to be calculated or is already imposed
- Contractual documentation is precise for a vendor of this size: a per-operation AI credit tariff, a plan comparison table and eight named subprocessors with their roles and policies
- Thirty-day trial on every feature with no card, followed by a permanent free tier with no time limit
- No commitment at all: monthly billing, cancel at any time, and you pay only for the period used
- Real per-seat degressivity, free visitor seats up to the included quota, and an entry price confirmed on two independent first-party pages
Cons
- A very young and very small publisher: a sole proprietorship registered on 3 April 2025 with two to ten people declared, which is a continuity risk worth weighing
- No public API, no named third-party integration, and no mobile or desktop application: the product is a browser tool that stands alone
- AI assistance is rationed by non-rechargeable credits, so once the monthly quota is spent the assistant is unavailable until it renews
- Tight ceilings: fifty tasks per project on Standard, 150 on Premium, twenty users maximum and 5 MB per attachment
- No security certification is claimed, and no hosting country or region is published, only a clause allowing some providers to process data outside the EEA
- Whether customer content is used to train AI models is never addressed anywhere on the site, and no opt-out is documented
- The free tier is not a sign-up path: it only applies if you let the trial lapse, and it excludes the structured mode entirely
Pricing & Plans
A permanent free tier is available, but it is not something you subscribe to: it applies automatically inside the application at the end of the thirty-day trial if no paid plan is chosen, and it is limited to one project in simplified mode. The trial itself lasts thirty days, covers every feature and requires no payment card. The cheapest paid entry point is the Standard plan at 15 EUR per user per month, quoted inclusive of tax and billed monthly with no commitment. Per-seat pricing is degressive above the second seat, and the Premium plan starts at 25 EUR per user per month. The vendor describes these amounts as indicative and reserves the right to adjust them with prior notice.

Data, GDPR & hosting
A consolidated view of how Orchesia handles your data.
GDPR overview
Implementation is concrete and unusually detailed for a vendor this small. The privacy policy, version 1.1.0 effective 13 August 2026, names the controller, claims compliance with Regulation (EU) 2016/679 in as many words, and sets out purposes, legal bases, retention periods and data subject rights, including the right to complain to the French CNIL. Answers are promised within one month, extendable by two. Article 6.4 names eight subprocessors and independent controllers with their role and privacy policy: Stripe, Vercel, Render, MongoDB Atlas, AWS S3, Google Analytics 4 with Tag Manager, Ahrefs Web Analytics and Brevo. A DPA is available on request and forms part of the contract. Transfers outside the EEA are covered by Article 46 safeguards. No DPO has been appointed, which the vendor states it is not required to do. No Article 27 representative is named, and none is needed since the controller is established in France.
Who owns the data?
Customers keep full ownership of everything they create, import or store in Orchesia, including projects, tasks, documents and files. The vendor takes only a limited, non-exclusive licence, restricted to hosting, storing, backing up, displaying and technically duplicating that content so the service can run, be maintained and stay secure. The terms state plainly that Orchesia claims no ownership over user content and never exploits it commercially. Under the GDPR the roles are split: Orchesia is the controller for account, billing, customer-relationship, security and website data, and acts as a processor towards the customer for the project content itself. The Orchesia name, source code, design and logo remain the vendor's, and the trademark is registered with the INPI.
Reuse rights
Customers may reuse their own content freely: they never transfer ownership, and the licence granted to Orchesia is limited to what running the service requires. On the vendor's side, the privacy policy enumerates the purposes and their legal bases: performing the contract for accounts, seats, billing and support; legitimate interest for security, fraud detection, service improvement, non-profiling internal statistics and legal defence; legal obligation for accounting records; and consent for optional marketing and non-essential cookies. No automated decision produces legal effects. Administrators may access customer content only in exceptional, justified cases, under authorisation, minimisation and logging, and support access requires the customer's explicit prior agreement. Data is neither sold nor rented. AI assistance runs on Anthropic's Claude models, declared as a subcontractor. One point is simply not addressed anywhere on the site: whether customer content is used to train AI models, and whether any opt-out exists.
Data retention & training
Hosting summary
The publisher names four hosting providers and their roles in the terms and the privacy policy: Vercel for the front end, Render for the API and backend, MongoDB Atlas for the database, and AWS S3 for files and backups. The legal notice gives Vercel Inc. in Walnut, California, and Render, Inc. care of an Irish compliance address in Dublin. No hosting country or region for customer data is declared anywhere on the site. The privacy policy states only that no transfer outside the EU or EEA takes place without safeguards meeting Article 46 of the GDPR, and that some providers may process data outside the EEA, for example in the United States, under standard contractual clauses, transfer assessments, encryption and minimisation. On security, data is encrypted in transit over HTTPS and at rest in the database, attachments and backups, but the service is explicitly not end-to-end encrypted: the keys are held by the vendor's servers. Passwords are hashed and salted, sensitive administrative access is logged for twelve months, and breaches are notified to the French CNIL within seventy-two hours.
Things to keep in mind
Risks and trade-offs to weigh before adopting Orchesia.
- The publisher is a sole proprietorship, not a company: there is no share capital and no legal person separate from the individual, so continuity and liability rest on one person, even though the terms occasionally speak of "the company Orchesia"
- The site names its hosting providers but publishes no hosting country or region; three of the four named providers are US companies, and the only statement on the subject is a transfer clause, which is not a hosting commitment
- Whether project content is used to train AI models is never addressed, and no opt-out is documented: assume nothing either way before putting sensitive project data into the tool
- No security certification such as ISO 27001 or SOC 2 is claimed, so any assurance you draw from the hosting providers' own certifications is theirs, not the publisher's
- AI-generated structures are persuasive precisely because they look complete; a plan you accepted without challenging its dependencies is a plan nobody has actually thought through, and the vendor itself insists that you validate each suggestion
- Prices are described as indicative in the sales terms and can be adjusted with prior notice, and downgrading from Premium to Standard requires the publisher's written agreement
- The free tier cannot be chosen on the website: it only applies if the trial is allowed to lapse, and it drops the structured mode, so plan the transition before day thirty
Setup & Integrations
Technical difficulty
Very low. There is nothing to install and nothing to configure: you register on app.orchesia.com, the thirty-day trial starts immediately and no payment card is asked for. No integration, API key or technical setting is documented, and the AI produces a first structure from a single sentence. The only administration is managing user and visitor seats. The real learning curve is methodological rather than technical, since the tool assumes you are willing to work with a work breakdown structure, dependencies and a critical path; the publisher sells its own training courses for exactly that.

Should you pick Orchesia?
Orchesia occupies a narrow slot on purpose. Most project tools help you run work that has already been framed; this one attacks the framing itself, and its AI is aimed at the work breakdown structure, the dependencies and the critical path rather than at spitting out another checklist. That focus is genuine and it is the main reason to look at the product: the assistant proposes, you validate every step, and the schedule comes out of the structure instead of being typed into an empty grid.
The reservations are those of a very young, very small vendor. The publisher is a French sole proprietorship registered on 3 April 2025, with two to ten people declared, and there is neither a public API nor a single named integration, nor a mobile application. Ceilings are tight — fifty tasks per project on Standard, twenty users at most on Premium — and AI assistance stops once the monthly credits run out, since none can be bought. No security certification is claimed, no hosting country is published, and the question of whether customer content trains AI models is simply never raised. Against that, the contractual documentation is more precise than most vendors of this size manage, down to a per-operation credit tariff and eight named subprocessors.
The natural audience is a small delivery team, up to twenty people, in an agency, an engineering office, construction, audiovisual production, a game studio, an event organiser or a training provider, that has to commit to a date and hold it. The cost of finding out is nil: thirty days with every feature and no card, then a permanent free tier if you decide against it. What deserves a second look before committing is hosting location and the silence on model training.
