ThinkWell - Offline Companion

SeMo Lab

About this app

ThinkWell runs real AI language models directly on your phone. No cloud, no account, no subscription. Once a model is downloaded, everything happens on your device — even in airplane mode.

WHAT YOU CAN DO
• Chat with a local AI, streamed word by word
• Ask about images — photos, screenshots, documents, charts
• Speak to it — record a voice note or attach an audio clip
• Write and edit — summarize, rewrite, draft replies, translate
• Code — syntax-highlighted answers, copy any block with one tap
• Math — real formula rendering, not raw LaTeX symbols
• Tables — export any table the model produces to Markdown or CSV

12 GUIDED WORKFLOWS
Decide · Plan · Debug · Brainstorm · Pros & Cons · Explain · Summarize · Rewrite · Reply · Review code · Critique · Translate

Each one steers the model through a clear, sectioned answer instead of a wall of text.

CURATED MODELS
Gemma · Qwen · Llama · Phi · Mistral · DeepSeek · SmolLM · LFM · IBM Granite · GLM-Edge · Nous Hermes

You can also import any GGUF file you already have.

What’s new

• Play your recordings: tap play on an audio clip, before or after sending it.
• Time on every message: messages, replies and the conversation list show dates and times.
• Sharper memory: it keeps what you say about yourself and recalls it only when relevant.
• More room to type: on narrow screens, attachment buttons fold into one while typing.
• Large photos now work with models that read images.
