Group SynthesisBeta
Give several AIs different jobs on the same task, then merge their work into one deliverable.
This page is the public explain. After you sign in, the Beta workspace is at /group-synthesis. The feature is shipped, still settling, and marked Beta in the app.
How Group Synthesis works
Write one brief
Describe the task once. You are not pasting the same prompt into six tabs.
Give each model a job
Roles such as lead, researcher, builder, analyst, QA, and reviewer can run on different models. You choose which roles are active.
Merge into one deliverable
The reviewer role merges the other outputs into a single piece of work you can refine or export.
Different jobs, same task
Each role gets its own job on the brief. That is the point: not six copies of one answer, but complementary work that can be merged.
One deliverable
The merge step produces a single output you can refine, export, or send to Me-Mic so the finished piece sounds like you.
Alongside compare, not instead
Need the same prompt on many models? Use Compare, then Synthesis. Need roles on one task? Use Group Synthesis. Both live in the same workspace.
Not a compare-only tab farm
LettiB is built as a multi-AI workspace with projects, memory, and a merge step. Group Synthesis is the role-based path: several models, distinct jobs, one deliverable. It is not a single assistant chat, and it is not a leaderboard of identical prompts.
Group Synthesis FAQ
What is Group Synthesis?+
Group Synthesis is a LettiB workspace that gives several AIs different jobs on the same task, then merges their work into one deliverable. It is in Beta. You assign roles — such as lead, researcher, builder, analyst, QA, and reviewer — pick a model for each role, and LettiB merges the role outputs into a single result you can refine or hand off.
Who is Group Synthesis for?+
It is for people who already use more than one model and want a finished piece of work, not a pile of parallel answers. Typical jobs are a spec, a research memo, a plan, or a review pass where each role has a distinct job on the same brief.
How is Group Synthesis different from compare-only tools?+
Compare-only tools send the same prompt to many models and stop at a side-by-side readout. Group Synthesis assigns different jobs, then merges those contributions into one deliverable. LettiB still has side-by-side compare and a separate Synthesis step for one-prompt, many-model runs. Ask once. Get one best answer.
