The thesis

The right AI changes per task.

Different frontier models genuinely lead at different things. The gaps are large enough to matter — and large enough to be the reason you switch tabs all day.

Claude

Real coding & long-form writing

Leads SWE-bench Verified for real-world repo-level coding and tops LMArena's creative-writing leaderboard.

ChatGPT

Hard reasoning & math

GPT-5 and o3 lead GPQA Diamond (~88%) and competition math (AIME ~95%). Also tops MMMU for multimodal understanding.

Gemini

Long context & visual reasoning

1M+ token window, with the best retention past 128K on RULER. Leads MathVista for charts and visual math.

Perplexity

Cited web research

Industry-leading citation density and source transparency for live web queries — every claim linked inline.

Generative-search audits

You shouldn't have to choose one. SessionBridge moves your conversation across them in one click — so you stop copy-pasting between four tabs. Scores current as of early 2026 and shift every few months.

How it works

Three steps. Two seconds.

  1. 01

    Compress

    SessionBridge reads the open conversation and distills it into a structured handoff — goal, decisions, current problem, next step. Not just the text. The thinking.

  2. 02

    Carry

    One click sends the compressed context to your chosen AI. New tab opens with the handoff prefilled — ready to send, or edit first.

  3. 03

    Continue

    The next model picks up exactly where the last one stopped. No re-explaining. No wall of pasted history. Just the thread, restored.

More than transfers

A full toolkit for working across AIs.

Hear every reply

Toggle voice on per AI. Natural neural voices read replies aloud the moment the model finishes — even when the tab is in the background.

Multi-phase projects

Plan a workflow across the right AIs — research with Perplexity, architecture with Claude, polish with ChatGPT. Each phase carries the previous output forward automatically.

Export your work
