English from shows and news — with an AI conversation partner
An English app where AI generates almost all the learning content on LangGraph — words in context, stories, exercises — plus a voice partner.
The context
Words from shows and videos are forgotten by the next day, and textbooks are cut off from real speech. Ordinary apps drill through lists with no context — dull, and nothing sticks.
The idea
We built an app where AI is the engine: almost all the learning content is generated on LangGraph for the user’s level. Words are shown in two contexts — “in the show” and “in life” — daily stories and exercises assemble automatically, and an ElevenLabs voice partner lets you speak out loud. Spaced repetition brings words back in time so they stick.
What we built
A multi-agent graph on LangGraph
Content is built not by a single prompt but by a graph of agents: an architect plans, a generator writes, a critic checks the content, a translator translates, a second critic proofreads the translation, and if phrases are missing from the dictionary, a separate step fills it in.
A dictionary from content
Save a word and AI explains it in two contexts — “in the show” and “in life.” Alongside are ready Oxford 5000 lists by level, A1–C1.
AI conversation partner
Speak English out loud: a LangGraph agent leads the dialogue and ElevenLabs voices it — real speaking practice without a teacher.
Smart practice
Spaced repetition and reminders bring words back at the right moment so your vocabulary doesn’t fade.
Daily Drops
AI generates short stories from fresh news at the user’s level — daily reading practice you actually want to open.
Screens
Tessera didn’t build “yet another vocabulary app” — they built an engine that explains a word through content and lets you talk to AI. That’s what keeps people in the app.
In Wispy, AI is the engine: almost all the learning content is generated on LangGraph for the user’s level, and an ElevenLabs voice partner gives real speaking practice. English is built into what people already watch and read.
