Features
Everything you need to capture, connect, search, and protect your knowledge.
Get ideas in fast, sort them later
No decision about where something goes. Just get it in. The AI handles routing.
QuickCapture
Voice Capture
Speak your thought. Whisper transcribes it into a searchable Pearl. No typing required. Just talk and it becomes knowledge you can find later.
Web Clipper
Browser extension that clips any page, including Gemini, Perplexity, and other AI chats that do not have native export. Clean extraction, not a screenshot. Actual content.
Forms
Structured data capture with templates. Define a repeating pattern once, fill it quickly. Each submission creates a Pearl with all the structured metadata intact.
Structure that does not fight you
Three simple building blocks. No folder maze. No complexity tax.
Pearls
The atom of knowledge. A Pearl is one idea: a note, an uploaded file, a web clip, an extracted insight, a voice recording. Searchable, linkable, permanent.
Buoys
Group related Pearls together. Nest them for hierarchy when you need it. Think of Buoys as flexible containers that bend to your mental model, not the other way around.
Nets
Big-picture domains like People, Projects, Ideas, or Signals. Nets give your knowledge a lightweight top-level shape without forcing you to organize before you are ready.
Harbors
Fully isolated workspaces. Keep Work and Personal completely separate. Different themes, different AI contexts, zero data leakage between them.
Landmarks
Visual markers on your Swim. Pin important locations in your knowledge landscape and navigate back to key areas instantly.
Auto-Linking
FlowTether detects connections between your Pearls and suggests links. Ideas find each other. You do not have to remember they exist.
Tags & Metadata
Tag anything. Filter everything. Automatic sentiment classification detects the tone of your content. Custom tags, topic tags, all searchable.
List View
Sometimes you want rows and columns. List view gives you a spreadsheet-style lens on your containers for bulk operations and sorting.
AI that works with your knowledge
Not another chatbot. AI woven into every layer: classifying, connecting, surfacing, and helping you think.
SlipStream
Lumi
Your context-aware AI assistant. Warm, direct, no hedging. Lumi knows where you are in FlowTether and offers help that is actually relevant to what you are doing.
Manifest
Long-form document assembly. Pull together Pearls from across your knowledge base into a structured document. Export as Markdown or HTML, with PDF and DOCX coming soon.
Tides (Calendar)
Time-based view of your knowledge. See upcoming signals, events, and recurring nudges. Your knowledge on a timeline, not just in a list.
Focus Timer
Built-in Pomodoro with Herald Fish companion. Work, rest, drift. An ambient aquarium screensaver for break time. Focus without leaving your workspace.
Find the idea, not the file
Search by meaning or by exact phrase, across every source, every format, in one query.
Semantic Search
Search by meaning, not just keywords. Ask "what did I decide about pricing last month?" and get results across notes, AI conversations, PDFs, and spreadsheets. The search understands what you meant, even if you do not remember the exact words.
Full-Text Search
When you know the exact phrase, full-text search has your back. Both search modes work together, with hybrid results ranked by relevance.
Cross-Source Results
One search spans everything: notes, AI conversations, imported documents, web clips, voice recordings, spreadsheet rows. No more searching five different apps to find one idea.
Import from the tools you actually use
12+ sources and growing. Your scattered data, unified and searchable the moment it arrives.
ChatGPT Import
Import your entire ChatGPT conversation history. Every chat becomes searchable in seconds. Extract key insights into permanent Pearls instead of losing them in a scroll.
Claude Import
Bring in your Claude conversations. Months of AI dialogue, finally searchable and connected to the rest of your knowledge instead of trapped in a separate tool.
Notion Import
Pages and databases from Notion. Your content preserved and enhanced with semantic search you never had in Notion. A real alternative for people who outgrew it.
Obsidian Import
Full vault import. Your markdown files, wikilinks, and folder structure all preserved, and now searchable by meaning, not just filename.
Roam Research Import
Pages and blocks with references. Your knowledge graph, now part of a bigger picture with AI that actually understands the connections.
Evernote Import
Bring your years of collected notebooks and notes with you. Your old archive, finally searchable again and connected to everything else.
PDF, DOCX & Markdown
Drop in documents. Full text extraction, searchable immediately. The three formats that hold most of the world's knowledge, all welcome here.
Excel & CSV
Turn spreadsheets of ideas, contacts, research data, or project lists into searchable knowledge. Column-aware import that preserves your structure.
Web Clipper
Browser extension that clips any webpage, AI chat, article, or reference. Clean extraction of actual content, not a screenshot.
Voice (Whisper)
Speak and it becomes searchable text. Whisper transcription means your spoken thoughts are first-class knowledge, not ephemeral audio files.
Confluence Import
Bring your team's institutional knowledge out of the Atlassian walled garden and into a system where you actually own it. Full space and page hierarchy preserved.
Your data is never trapped
Data portability is a right, not a premium feature. Export anything, anytime, in formats that make sense.
Real Export
Export your entire knowledge base or just the pieces you need. JSON, Markdown, PDF, or DOCX. No complicated export levers. No hoops. Formats that actually make sense outside FlowTether.
Manifest Export
Assemble Pearls into long-form documents and export as Markdown or HTML. PDF and DOCX export coming soon. From fragments to finished product.
Your knowledge, programmable
FlowTether is not just an app. It is infrastructure you can build on.
API Keys
Generate personal API keys for programmatic access. Build custom integrations, automate imports, or connect your own tools to your knowledge base.
MCP Server
Model Context Protocol lets AI tools like Claude and Cursor search and write to your FlowTether knowledge base directly. Your knowledge becomes your agent's persistent memory.
Privacy is not a setting. It is the architecture.
Most apps promise not to look at your data. FlowTether is built so we structurally cannot.
Harbor Isolation
Every workspace has full data isolation at the database level. There is no admin panel where anyone browses your knowledge. Your Harbor is yours alone.
AI Security Layer
Input sanitization, output scanning, injection defense, and prompt leak detection. The AI layer is locked down so your knowledge stays safe even when agents connect to it.
The Membrane
When AI tools connect via MCP or API, writes are rate-limited, quota-controlled, and security-scanned. Nothing crosses the boundary without proper authorization. Full approval queues are in development.
