Solva — why not just ChatGPT?
Free tax AI is already everywhere. The honest question: why Solva? Three differences a general-purpose AI can't hold.
Sourced & dated
Every answer cites the Légifrance article / the BOFiP guidance, dated to the tax year. No « in general »: the applicable rule, with a verifiable source.
Your situation
Solva starts from your calculation and your form — your regime, your figures — not a question asked cold into the void.
Wired to action
The answer leads to the right calculator, the right filing, the form to prepare. Understand then act, in one place.
5 free messages/day, no card — the entry wedge.
Solva & the Workshop — the real difference
Beyond the tools: a tax AI that cites its sources, and a virtual company where you learn by doing.
An answer in 30 seconds with cited sources — Légifrance, BOFiP, impots.gouv. Verifiable line by line, 15 countries.
Run a real simulated company: accounting, VAT, decisions — with Solva as your tutor. The only accounting “flight simulator”.

The director who handles their own admin.
- Solo director, SASU / EURL under corporate tax (beachhead)
- Freelancer / self-employed professional on the real regime
- Small business without a full-time accountant

vs Pennylane / Sage / Compta-online
Nous ne tenons pas votre comptabilite
Pennylane est un logiciel de tenue de compta pour cabinets ou PME integrees. ActioFin est une boite a outils de pilotage complementaire, pas un substitut.

Nous ne sommes pas une banque
Qonto et consorts sont des comptes pros bancaires (IBAN, carte, virements). ActioFin est complementaire : zero banque, juste les outils finance autour.
Qonto = payment institution authorised by ACPR (Banque de France) · ActioFin is not a bank or payment service provider

Nous ne remplacons pas votre expert-comptable
L'expert-comptable est un professionnel reglemente (art. 2 ord. 1945) qui tient votre compta et depose vos liasses. Nous vous faisons gagner du temps sur les taches repetitives en amont et en aval.

14-day trial — no cardFrequently asked questions
Is it really free?
Yes: calculators, form guides and articles are unlimited and card-free. You only pay if you want a finished deliverable (a filled form, per unit) or the unlimited plan (Pass Pro).
Does ActioFin e-file my returns?
No. ActioFin prepares and checks; you validate and file yourself. No transmission to the tax authority or social bodies from our servers.
How is Solva better than a free AI?
Solva cites its dated official sources, starts from YOUR calculation/form, and leads to concrete action — where a general AI answers out of context and without a verifiable source.
Do I need an accountant?
ActioFin is a copilot, not a firm. You can file yourself, hand off to your accountant, or use a partner accountant — you choose the ramp.
