How Lynse works
Your recording, your workflow
AI builds the summary structure
Start with a recording. Lynse analyzes that conversation and writes a structure suited to what was actually discussed. You can also type the points you care about and have AI create a template, without browsing a template library first.
Free access through Lynse Skills
Authorize an AI assistant to use your recording-related data: recordings, transcripts, summaries, folders, to-dos and devices. The access interface is permanently free without a subscription. New transcription and generation follow their normal quota and billing rules.
FAQ
Things You Might Want to Know
SparkCard combines recording and transcription with LynClaw, an AI agent for your recording library. It can help turn a conversation into meeting minutes, task lists and other outputs, then answer follow-up questions about the recording.
LynClaw is built into the Lynse recording workflow. It can work with your authorized recordings, transcripts and summaries, help analyze multiple recordings, and create notes or tasks. Lynse Skills also lets you connect your recording-related data to other AI assistants, subject to your authorization.
Yes. SparkCard uses bank-level end-to-end encryption, and your recordings are never used for AI model training. Our parent company Century Huatong operates its own supercomputing center, with data stored on compliant domestic servers that meet data-security regulations.
SparkCard uses a MagSafe magnetic design and is compatible with iPhone 12 and later. Android users can use the included magnetic adapter sticker. See the product guide for the full list of compatible models.
We support automatic recognition and transcription for 120+ languages, including Mandarin, Cantonese, English, Japanese, Korean, and other major languages. No manual switching is needed, as the system detects the language automatically.
Files generated by the app can be pushed directly to WeChat, Feishu, and DingTalk. By connecting general AI agents like OpenClaw, you can also process your recording assets directly within WeChat or Feishu without switching apps.
No. After binding SparkCard, you receive 1000 free transcription minutes per month. Standard members can buy a one-time credit pack for extra transcription in the app without subscribing. One credit covers one minute; packs remain valid for 365 days. Pack prices and sizes appear in the app before purchase.
No. Lynse AI can analyze the conversation and create a structure tailored to that recording. You can also enter key points and ask AI to create a template. Selecting an existing template is optional.
The Lynse Skills access interface is permanently free and does not require a subscription. With your authorization, an AI assistant can access recording-related data such as recordings, transcripts, summaries, folders, to-dos and devices. New transcription or AI generation still follows applicable allowance and billing rules.
