ChatADV — #3 in AI for lawyers

## Alternatives in AI for lawyers

- #1 **Jus IA** — Jusbrasil · Has a free plan
   Why it ranks here: Brazil's largest legal database, with validated case-law citations, a model specialized in Brazilian law, free experimental access and prices published in reais; the entry plans cap the number of messages.
   Official site: https://ia.jusbrasil.com.br

- #2 **Jurídico AI** — Jurídico AI · Has a free plan
   Why it ranks here: It covers the main legal tasks under Brazilian law, has a permanent free plan with no card and a price published in reais, but the free plan is quite limited and the official site doesn't detail the price of each paid plan.
   Official site: https://juridico.ai

- #4 **Lexter** — Juristech Inteligência Artificial · No free plan
   Why it ranks here: It covers real legal tasks in Portuguese and publishes a single price in reais, but it offers no free plan or advertised trial on its site and costs more than the options above.
   Official site: https://lexter.ai

- #5 **Turivius** — Turivius · No free plan
   Why it ranks here: It has the largest decision database among the Brazilian tools in the group and answers with sources, but the official site doesn't publish prices and the free trial is mentioned without duration or terms, so it sits behind the options with published prices.
   Official site: https://turivius.com

- #6 **CoCounsel** — Thomson Reuters · No free plan
   Why it ranks here: It covers research, drafting and review with curated Brazilian legal content in Portuguese, but the official site doesn't publish prices or offer a free trial, only a demo; it ranks above Spellbook because it covers Brazilian law.
   Official site: https://www.thomsonreuters.com.br/pt/produtos/cocounsel.html

- #7 **Spellbook** — Spellbook · No free plan
   Why it ranks here: Strong at contract review and drafting, but the site doesn't mention Brazilian law or Portuguese, the price isn't published and there's only a 7-day free trial.
   Official site: https://spellbook.com
