How it works

Three steps,
zero context lost.

No manual copy-pasting, no summaries. SessionPort reads, formats, and injects — you just pick the platform.

01 / CAPTURE
⚡
One click, full snapshot
Open the side panel on any supported platform. Click Capture — SessionPort reads the full conversation and saves a structured JSON snapshot: decisions made, approaches rejected, open questions, history.
02 / TRANSFER
↗
Switch platform, click Paste
Open the target AI platform. Click Paste in the panel — SessionPort formats the snapshot and injects it directly into the input field. Works with ProseMirror, Quill, and contenteditable editors.
03 / CONTINUE
⟳
The new AI just continues
The target AI receives the full context — history, what was decided, what was rejected — and continues naturally. Switch platforms as many times as you need. Every state is saved in history.

U
I want to build a reading tracker app — books, pages per day, streaks. What's the right tech stack for a solo developer?
C
For a solo dev I'd go with React Native + Expo — one codebase for iOS and Android. Backend: Supabase for auth + Postgres + realtime. Streaks: store reading_date as DATE in user's local timezone — never derive from UTC server-side, that's the classic edge case...
U
Decided on React Native + Expo + Supabase. DATE-based streaks. What's the book data model?
C
Table books: id, user_id, title, author, total_pages, status. Table sessions: id, book_id, reading_date, pages_read. Streak is computed from sessions grouped by date...

Prompt Library

Write once,
insert everywhere.

Build your personal library of reusable prompts. Insert any prompt into any of the 7 supported AI platforms in one click — with variable substitution and file attachments.

🔤
Variables {{name}}
Add placeholders to any prompt. Before inserting, SessionPort asks you to fill them in — the final text is assembled and injected instantly.
🏷️
Tags & search
Organize prompts with custom tags. Filter by tag or search by title — find what you need without scrolling through the whole library.
📎
Attach files
Link a file to a prompt — it gets attached to the AI input automatically when you insert. Perfect for code reviews, templates, or reference docs.
☁️
Sync via Google Drive
Prompts sync automatically to your Google Drive alongside snapshot backups. Switch devices without losing your library.
Prompt Library 12 prompts
★ Code review
Review {{language}} code in {{file}}. Focus on: security, performance, readability.
devreview
Explain like I'm 5
Explain {{concept}} in simple terms, no jargon.
learning
Refactor for readability
Refactor the following code. Keep behaviour identical. Improve naming, reduce nesting.

Visual history

Sessions mapped
like a git tree.

Every capture, fork, and platform switch is visualized as an interactive graph. Click any node to restore that exact snapshot.
