JUPUS
JUPUS is a German AI secretariat for law firms, combining a phone assistant, digital client intake and document AI. It answers calls, opens case files and drafts pleadings from over a million court rulings.
What is JUPUS?
JUPUS is an AI secretariat built for German law firms. It comes from JUPUS GmbH in Cologne, founded in 2022 by lawyer René Fergen and engineer Jannis Gebauer and now more than eighty people, and exists to absorb the administrative work that used to fall to Rechtsanwaltsfachangestellte, a profession disappearing fast from the German market.
The platform holds three modules, sold together or separately. Telefon-KI Marie answers the phone day and night, works out the area of law and whether the caller is a prospective client, an existing one or the opposing side, documents the conversation and forwards important calls according to rules the firm sets; a structured summary follows by email. The KI-Sekretariat gathers six building blocks around client intake: a website chatbot, online appointment booking, electronic signature, area-specific questionnaires, a searchable overview of every enquiry and one-click file creation. The Dokumenten-KI does the legal work itself, reading contracts, decisions and case bundles, searching more than a million German court rulings and drafting pleadings from the firm's own templates. A standalone AI Chat is sold separately, offering managed access to OpenAI and Anthropic models with document upload, folders and multi-seat administration.
What sets JUPUS apart is less the AI than the compliance envelope around it. Data is processed and stored in the EU, the subprocessors are published by name, and training the underlying models on client data is contractually excluded in three separate documents. The vendor claims conformity with the GDPR, with the professional rules binding German lawyers (BRAO §43a and §43e, §203 StGB on professional secrecy) and with the EU AI Act. It plugs into the case-management systems firms already run, among them DATEV, RA-Micro, ACTAPORT, advoware, Kleos and ADVOLUX, rather than replacing them.
JUPUS claims more than 2,000 lawyers using it daily, over a million matters processed and 53% less manual work. Answers come with their sources, but the legal judgement and the final decision stay with the lawyer: JUPUS provides no legal advice.
What it does
- Answer the firm's phone around the clock, identify the caller and the area of law, and route the calls that matter
- Capture case facts through area-specific digital questionnaires that clients fill in themselves, phone included
- Open a complete case file in the firm's existing software in one click, with no retyping
- Analyse contracts, decisions and case bundles running to hundreds of pages
- Search more than one million German court rulings and return authorities with their sources
- Draft pleadings, claims and letters from the firm's own templates
- Collect digital signatures on powers of attorney and engagement letters
When to use JUPUS / When not to
A quick filter to help you decide if JUPUS is the right fit.
When to use JUPUS
- German law firms of any size that lose billable hours to phone calls, retyping and file creation
- Sole practitioners and small practices with no secretarial support, as the Rechtsanwaltsfachangestellte profession thins out
- Firms working in employment, family, tenancy, traffic, criminal, inheritance, contract, social, medical or insolvency law
- Practices committed to a case-management system such as DATEV, RA-Micro, advoware or ADVOLUX and unwilling to migrate away from it
- Teams with little appetite for technology, since setup, integration and staff training are handled by JUPUS at no charge
When not to use JUPUS
- Private individuals and consumers, who are excluded by contract: the terms serve businesses and public-law bodies only
- Lawyers practising outside Germany, since the interface, the procedure and the case-law corpus behind the research are all German
- Anyone expecting legal advice from the tool itself, which explicitly provides none under the Rechtsdienstleistungsgesetz
- Developers wanting to build on top of it: there is no public API, no developer documentation and no mobile application
- Firms looking for a permanently free option, since access simply stops once the trial period ends
How to use JUPUS
A typical end-to-end flow, from setup to results.
- Book the free 45-minute demo on the JUPUS website, held on Microsoft Teams and tailored to your practice areas
- Or skip the sales route and start a trial directly: seven days on the AI Chat, fourteen days on Telefon-KI Marie
- Register with an email address, your firm's name and confirmation that you are contracting professionally; no card details are needed for the trial
- For Marie, receive your number and set the greeting, the transfer rules and the opening hours, and she is live in roughly ten minutes
- For the KI-Sekretariat, work through the dedicated onboarding programme with a named contact, at no charge
- Have JUPUS connect the platform to your existing case-management software
- Take the team training, spread over several sessions if needed, and keep working in the tools your staff already know
- Day to day, let Marie take the calls and let clients complete the digital questionnaires themselves
- Forward emails and upload scans or documents, then let JUPUS extract the facts and open the file
- Review every draft before it leaves the office, and reach support by email or through the help centre
Pros & Cons
Pros
- Genuine legal specialisation: trained on German case law and firm workflows, not a general assistant in legal clothing
- A compliance envelope rare at this depth, covering the GDPR, BRAO §43a(2) and §43e, §203 StGB and the EU AI Act
- Processing and storage in the EU, subprocessors published by name, and no third-country transfer for the AI Chat
- Training of the language models on client data is contractually excluded, and stated in three separate documents
- The client keeps every right in both the input and the generated output
- Setup, connection to your case-management software and team training are included at no extra cost
- Trials without a card, seven days on the AI Chat and fourteen on Marie, with monthly cancellation on the phone AI
Cons
- A single market: the interface, the procedure and the case-law corpus are German, which makes the tool unusable elsewhere
- No public API, no developer documentation and no mobile application
- No permanently free plan; once the trial ends, access stops
- Pricing is hard to read: the KI-Sekretariat charges 97 EUR per user plus a further 97 EUR platform fee, both net of VAT, at the annual rate
- The standalone AI Chat prices appear only in the terms of use, never on the pricing page, and the KI-Sekretariat cannot be bought online at all
- Monthly token quotas on the AI Chat lock the account until the next period, with no top-up and no carry-over of what went unused
- No independent certification such as SOC 2 or ISO 27001, and several product screenshots still read "Mockup folgt"
Pricing & Plans
There is no permanently free plan. Free trials are offered, seven days on the AI Chat without payment details and fourteen days on Telefon-KI Marie, but access ends when they expire. The lowest paid entry point is 29.90 EUR net per user per month, for the AI Chat Beginner package published in the terms of use. On the pricing page itself the range starts higher, at 97 EUR per user per month for the KI-Sekretariat at the annual rate plus a 97 EUR platform fee, and at 99 EUR per month for Telefon-KI Marie. All amounts are quoted net of VAT, and no setup fee is charged.

Data, GDPR & hosting
A consolidated view of how JUPUS handles your data.
GDPR overview
GDPR implementation is documented rather than merely claimed. JUPUS GmbH names itself controller for the website and processor under Article 28 for everything entered in the product, on the basis of a data processing agreement published at jupus.de/avv and signable digitally in the customer cockpit. The privacy notice, drafted by an outside law firm, sets out access, rectification, erasure, restriction, withdrawal, objection, portability and the right to complain to a supervisory authority, all exercisable at hello@jupus.de. No data protection officer is named and no Article 27 representative exists, which is consistent for a controller established in Germany. Beyond the GDPR the vendor claims conformity with BRAO §43a(2) and §43e, with §203 StGB on professional secrecy, and with the EU AI Act. No independent certification such as SOC 2 or ISO 27001 is published.
Who owns the data?
All rights in both the input and the generated output stay with the client. JUPUS receives only a simple licence, limited to the term and the purpose of the contract, allowing it to use that material to deliver the service, run quality control, keep the system working and improve the product on anonymised data. Legally JUPUS acts as a processor under Article 28 GDPR while the firm remains the controller, and the professional-secrecy duties of §43e BRAO, §26a BNotO and §203 StGB are expressly preserved. Users and administrators may delete content at any time, and an administrator can purge an entire account irreversibly.
Reuse rights
The client keeps every right in what it uploads and in what the AI produces, so an output can be reused, edited, filed with a court or handed to a client without asking JUPUS for permission. The only stated condition is professional: a lawyer must check the result first, because AI output is not legal advice and does not replace legal assessment. JUPUS's own use of the material is narrow. Customer data never trains the third-party language models, an exclusion written into the general terms, the AI Chat terms and the security page alike, and product improvement is permitted only on anonymised data. The subprocessors are named outright: Amazon Web Services EMEA and Microsoft Ireland for hosting, OpenAI Ireland for the ChatGPT models and AWS EMEA again for Anthropic's Claude, all processing inside the EU with no third-country transfer.
Data retention & training
Hosting summary
Customer data is processed and stored in the European Union. The AI Chat terms state this twice, the security page speaks of certified European data centres, and the processing agreement adds encryption in transit and at rest, regular backups, access controls and audit logs. Annex A of the AI Chat terms goes further than most vendors and names the subprocessors outright: Amazon Web Services EMEA for hosting and storage, Microsoft Ireland likewise, OpenAI Ireland for the ChatGPT models and AWS EMEA again for Anthropic's Claude. Every line carries the same note, processing in the EU with no third-country transfer. No individual hosting country is named. The site stops at the EU, and the addresses given in Annex A are corporate seats rather than data centre locations, so they should not be read as hosting jurisdictions. One qualification applies to the marketing site alone and not to the product: Amazon CloudFront distributes its content through a global network, and the privacy notice concedes that transfers to third countries may occur there under standard safeguards. The server answering jupus.de is a CloudFront node in Frankfurt.
Things to keep in mind
Risks and trade-offs to weigh before adopting JUPUS.
- The headline price hides the shape of the bill: 97 EUR per user assumes an annual commitment and sits on top of a separate 97 EUR platform fee, both before VAT
- Over-reliance is the real professional risk, because the tool drafts confidently and cites its sources, which makes a cursory review feel sufficient while the lawyer remains fully liable for whatever leaves the office
- Liability for the inherent failures of the third-party models, hallucinations and bias included, is contractually disclaimed by the vendor
- You are not entitled to any particular model or provider: JUPUS may replace one with an equivalent at its own discretion
- Token quotas on the AI Chat can lock an account in the middle of a matter until the next billing period, with no top-up and no carry-over
- Compliance is declarative, with no SOC 2, no ISO 27001 and no published external audit, so a firm bound by professional secrecy is trusting the vendor's own statements
- Three separate contractual documents govern the service, two of them hosted on a third-party domain, which makes it easy to sign without having read the terms that actually apply
Setup & Integrations
Technical difficulty
Low, and deliberately so. Telefon-KI Marie is live in about ten minutes: you register, receive a number and set the rules, with no installation and no technical prerequisites. The AI Chat is pure self-service. The KI-Sekretariat is the only part that needs help, and JUPUS supplies it free, through a dedicated onboarding programme with a named contact, connection to your case-management software, and training for the whole team over several sessions if wanted, followed by a permanently reachable Customer Success Manager. All the firm provides is an internet connection, a current browser and its own devices.

Should you pick JUPUS?
JUPUS is a vertical tool, very deep on a deliberately narrow market: the German law firm. That focus is its whole argument. The AI itself is not exotic, since it leans on OpenAI and Anthropic models like everyone else, but the envelope around it is unusually thorough and it addresses precisely what stops the profession from adopting these tools at all. Professional secrecy, BRAO obligations and the GDPR are not footnotes here; they are the opening pitch, backed by a published processing agreement, named subprocessors, EU-only processing and a contractual ban on training the models with client data.
The second strength is coverage. Most legal AI tools take one link in the chain. JUPUS takes the whole thing, from the phone ringing to a draft pleading, and does so without asking the firm to abandon the case-management software it already pays for.
The weaknesses are real too. This is a one-market product: outside Germany the language, the procedure and the million rulings behind the research are simply the wrong ones. There is no API and no mobile app. Nothing is independently certified, so the compliance claims remain the vendor's own. And the pricing is scattered across three documents, with a headline figure that quietly assumes an annual commitment and omits a second 97 EUR platform fee.
The traction is documented rather than asserted: more than 2,000 lawyers, over a million matters processed, some eighty staff and more than 20 million EUR raised across a seed round and a Series A.
The verdict is easy to state. For a German practice trying to absorb administrative load without changing its core software, JUPUS is a serious candidate. Anywhere else, it is beside the point.
