In their own words
Sotto
Sotto is open-source, self-hosted language-learning software for structured CEFR courses and private practice. Its course covers grammar, reading, listening, speaking, and writing, with advancement tied to demonstrated mastery; separate practice is not gated by course progression. A vocabulary and grammar memory graph uses SM-2 spaced repetition to schedule reviews and help shape adaptive listening. Learners can build classes from articles, papers, YouTube links, or topics, with material leveled to a CEFR course and citations provided. Configurable AI and speech services include OpenAI, Anthropic, Ollama, faster-whisper, and Kokoro; Gemini Live supports spoken translation. The application, database, and files run on the operator’s own stack, and the maker documents an offline setup using the learner’s hardware. Access options include a browser-installable PWA, a desktop launcher for macOS, Windows, and Linux, a terminal client, and workbook PDFs for iPad annotation. Sotto is free to run under AGPL-3.0, but users pay configured AI and speech providers directly. Content sent to cloud providers is subject to those providers’ terms.
Talkpal

Premium plans are listed for one, 12, and 24 months; each includes unlimited practice with all AI modes, personalized learning, detailed progress tracking, a pronunciation assessment tool, and AI daily feedback. Talkpal also lists a 14-day trial. Lessons are not available offline, so learners should expect to use the service online.

Stated company-size fit ranges from solo users and small organizations to mid-market and enterprise, though the product details focus on language practice.
