Thanks for sending the details over. The role sounds great, and I can start on 3 October if the timing works for them.
Kepler vs Tracker: the AI-first choice. Ask Kepler’s AI Chat in plain English and it finds, ranks and updates for you.
Kepler is a recruitment CRM you can talk to. Ask AI Chat a question and it searches your CVs, notes, emails and call transcripts, scores candidates for a job and suggests updates you approve. Tracker is sold in four plans, and its API, Sequencer and automations are only on the Professional plan, which is priced on request.
The short answer
The difference is how you work.
Kepler is a simple, modern CRM where you ask AI Chat in plain English instead of searching by hand. AI Chat is included on every plan, monthly and annual, with no add-on or upgrade needed.
Tracker is searched with Boolean and semantic queries, and it does not have a chat assistant across your records yet.
- Choose Kepler if
- You want a simple, modern CRM with the AI included. You would rather ask a question than build a search string, see a 0 to 100 score with the reason behind it, and approve updates instead of typing them in. You want one published price of USD 99 per user per month billed annually, with the API, campaigns, automations and client portal in it and the migration done for you.
- Tracker is built for
- An all-in-one staffing system sold in four plans, two of them priced on request.

The difference in practice
Ask about the conversations, not only the fields.
Kepler’s AI Chat sits on every page. Ask in plain English and it searches CVs, notes, emails and call transcripts together, so a match can come from something a candidate said on a call. Tracker searches with Boolean and semantic queries over its fields and parsed résumés, and it does not have a chat assistant across your records yet.

Kepler scores every candidate from 0 to 100 against the job. The criteria come from the job description and you can edit them. Each criterion shows the line from the CV, call or email behind it, so a consultant can see why. Tracker’s AI ranking learns from candidate engagement, past success in similar roles and recruiter feedback.

Assessment
A strong fit for the brief. Sophia has run a production Spark platform on AWS and has managed a team through a migration. Financial services exposure is via a payments client rather than a bank.

Nothing lands on its own
A call changes a record. You still get the last word.
Kepler reads the email, the call and the message and comes back with the change already written. Each one is a suggested update or task with its source attached, and you accept or reject it. Tracker’s Outlook and Gmail add-ins show a summary of the sender, and you create the record, note or task yourself.

Where the engine comes from
Not a first attempt at parsing CVs.
Kepler's CV parsing and formatting come from RemakeCV, built by the same team and used by 300+ recruitment agencies. The migration that fills your database on day one runs on an engine that has been reading real agency CVs for years, not on something written for this launch.
The 300+ figure is RemakeCV's agency count. The parser reading your archive is the one those agencies already run.
Migration
Get migrated in days.
Get migrated in days.
We handle the whole move.
-
1. Send us the export
Whatever your current system gives you, plus loose CVs and spreadsheets sitting in folders. Not sure how to export? We will walk you through it.
-
2. We build the migration
Extraction, mapping, de-duplication and validation, the unglamorous half most vendors leave on your desk. Your custom fields are recreated rather than flattened into notes.
-
3. You look at a sample
Fifty of your own records, fully parsed. Your people, not a demo set. Tell us what we got wrong and we re-run.
-
4. Everything loads
The full database goes in, mailboxes and calendars connect, and history backfills onto the right records. We stay on it until your team is working.

Questions, answered.
Is Tracker better than Kepler?
It depends on how you want to work. If you want a simple, modern CRM with the AI included, where you ask AI Chat in plain English and it finds candidates, ranks them for a job and updates records for you, choose Kepler. It is one plan at USD 99 per user per month billed annually, with the API, campaigns, automations and client portal in the price and a free migration. If you want an all-in-one staffing system sold in four plans, Tracker is built for that.
How much does Tracker cost compared to Kepler?
Kepler is USD 99 per user per month billed annually (USD 129 monthly), one plan with every feature included. The Tracker plan to compare is Professional, the first with the Sequencer, AutoAction, Watchdogs and the REST API, and as of 13 Sep 2026 it is priced “Contact Sales”. Tracker’s Core plan is USD 99 and Launch is USD 79 per user per month billed monthly, neither includes those features, and Tracker asks for a six-month minimum.
Does Tracker have an AI chat assistant?
Not yet. Kepler’s AI Chat sits on every page, searches CVs, notes, emails and call transcripts, returns lists you can save and asks for your approval before it changes anything. Tracker does not have a chat assistant across your records yet. TrackerAI today writes job descriptions, summaries, screening questions and outreach, and ranks résumés against a job.
Does Kepler write emails for me like TrackerAI does?
Yes. In any Kepler composer you say what the email should cover, and Kepler drafts it from the thread, the recipient’s record, recent notes and the job. You edit it and press Send. Tracker’s AI Content Suite writes emails, texts and job posts, from the Core plan up.
What does Kepler have that Tracker does not?
Kepler has AI Chat on every page, which answers across the whole database and acts after you approve. Tracker does not have a chat assistant across your records yet. Kepler has a meeting notetaker for Teams, Zoom and Google Meet, and Tracker does not have one of its own. Kepler also gives every candidate a 0 to 100 score with the reason behind it, suggests updates from emails and calls, and keeps history and undo on every field. The API, campaigns and automations are on Kepler’s one plan, where Tracker keeps them on Professional.
Can you migrate from Tracker to Kepler?
Yes, free on every Kepler plan. You send an export from Tracker plus any loose CVs and spreadsheets, and Kepler does the mapping, clean-up and checks. Custom fields are rebuilt as real fields, and activity, stages and history come across. You review fifty of your own records before the full load, and you can export your whole workspace at any time with no exit fee.
